[0004] An embodiment of the present disclosure may provide glasses.
The glasses may include a glasses frame and two speakers. The
glasses frame may include a glasses rim and two glasses temples.
The two glasses temples may be rotatably connected to the glasses
rim, respectively. The two speakers may include an earphone core.
The two speakers may be connected to the two glasses temples via
hinge components of the two glasses temples, respectively. Each
hinge component may be rotatable to change a position of its
connected speaker relative to one of the two glasses temples. The
glasses temple may include a control circuit or a battery. The
control circuit or the battery may drive the earphone core to
vibrate to generate a sound. The sound may include at least two
resonance peaks.

DETAILED DESCRIPTION
[0035] In order to illustrate the technical solutions related to
the embodiments of the present disclosure, the drawings used to
describe the embodiments are briefly introduced below. Obviously,
drawings described below are only some examples or embodiments of
the present disclosure. Those skilled in the art, without further
creative efforts, may apply the present disclosure to other similar
scenarios according to these drawings. It should be understood that
the purposes of these illustrated embodiments are only provided to
those skilled in the art to practice the application, and not
intended to limit the scope of the present disclosure. Unless
obviously obtained from the context or the context illustrates
otherwise, the same numeral in the drawings refers to the same
structure or operation.
[0036] As used in the disclosure and the appended claims, the
singular forms "a," "an," and "the" may include plural referents
unless the content clearly dictates otherwise. In general, the
terms "comprise" and "include" merely prompt to include steps and
elements that have been clearly identified, and these steps and
elements do not constitute an exclusive listing. The methods or
devices may also include other steps or elements. The term "based
on" is "based at least in part on," The term "one embodiment" means
"at least one embodiment;" the term "another embodiment" means "at
least one other embodiment." Related definitions of other terms
will be given in the description below. In the following, without
loss of generality, the "glasses" or "sunglasses" may be used when
describing the sound conduction related technology in the present
disclosure. The description is only a form of conduction
application. For those skilled in the art, "glasses" or
"sunglasses" may also be replaced with other similar words, such as
"eye protection device," "eye wearable device," or the like. In
fact, the various implementations in the present disclosure may be
easily applied to hearing devices other than the speaker. For
example, for those skilled in the art, after understanding the
basic principles of glasses, it may be possible to make various
modifications and changes in the form and details of the specific
methods and operations of implementing glasses without departing
from the principles. In particular, an environmental sound
collection and processing function may be added to the glasses to
enable the glasses to implement the function of a hearing aid. For
example, a microphone may collect environmental sounds of a
user/wearer, process the sounds using an algorithm and transmit the
processed sound (or generated electrical signal) to a speaker of
glasses. That is, the glasses may be modified to include the
function of collecting the environmental sounds, and after a signal
processing, the sound may be transmitted to the user/wearer via the
speaker, thereby implementing the function of the hearing aid. As
an example, the algorithm mentioned herein may include noise
cancellation, automatic gain control, acoustic feedback
suppression, wide dynamic range compression, active environment
recognition, active noise reduction, directional processing,
tinnitus processing, multi-channel wide dynamic range compression,
active howling suppression, volume control, or the like, or any
combination thereof.
[0037] Referring to FIG. 1, FIG. 1 is a schematic structural
diagram illustrating glasses according to an embodiment of the
present disclosure. In the embodiment, the glasses may include a
glasses frame 10 and a function member 20.
[0038] In some embodiments, the glasses frame 10 in the present
disclosure may include glasses frames of various glasses such as
short-sighted glasses, far-sighted glasses, sunglasses, 3D glasses,
etc., and be not limited herein.
[0039] The function member 20 may be connected to the glasses frame
10 so that the glasses may further have some other functional
modules or components. For example, the function member 20 may
include a speaker including a bone conduction speaker, an air
conduction speaker, or the like. Of course, the function member 20
may also include other components, such as a positioning device,
and be not limited herein.
[0040] In some embodiments, the glasses frame 10 may include a
glasses rim 11 and two glasses temples 12. The glasses temple 12
may include a main body 121 of the glasses temple and a hinge
component 122. The main body 121 may be rotatably connected to the
glasses rim 11. A speaker 21 may be connected to the glasses temple
12 via the hinge component 122.
[0041] FIG. 2 is a schematic structural diagram illustrating a
hinge component according to an embodiment of the present
disclosure. FIG. 3 is an exploded structural schematic diagram
illustrating a hinge component according to an embodiment of the
present disclosure. In some embodiments, the hinge component 122 of
the present disclosure may be used in glasses in some embodiment of
the present disclosure.
[0042] In the present disclosure, the hinge component 122 may
include a hinge 30. The hinge 30 may be a structure used to connect
two solids and allow a relative rotation between the two
solids.
[0043] Specifically, when the hinge component 122 in the embodiment
is used in the embodiment of the glasses described above, the hinge
component 122 may be disposed at an end of the main body 121 of the
glasses temple away from the glasses rim 11. The function member 20
may further be connected to the end of the main body 121 of the
glasses temple away from the glasses rim 11 via the hinge 30.
[0044] In some embodiments, the hinge component 122 may also
include a rod-shaped member 40 and a fixing member 50. In some
embodiments, the hinge 30 may include a hinge mount 31 and a hinge
arm 32. In some embodiments, the hinge arm 32 may be rotatably
connected to the hinge mount 31 via a rotating shaft 33. It is
easily understood that the hinge mount 31 and the hinge arm 32 may
be respectively connected to two members that need to be rotatably
connected. Therefore, the two members may be rotatably connected
together via the rotating shaft 33 of the hinge 30.
[0045] In some embodiments, the hinge mount 31 of the hinge 30 may
be connected to the rod-shaped member 40. In some embodiments, the
rod-shaped member 40 may be a partial structure or an integral
structure of one of the two members that are rotatably connected
via the hinge 30. Alternatively, the rod-shaped member 40 may be a
connection structure that connects one of the two members that need
to be rotatably connected to the hinge 30. When the hinge component
122 in the embodiment is used for the glasses, the rod-shaped
member 40 may be at least a portion of the main body 121 of the
glasses temple of the glasses. For example, the rod-shaped member
40 may be the entirety of the main body 121 of the glasses temple.
Alternatively, the rod-shaped member 40 may be a portion of an end
of the main body 121 of the glasses temple away from the glasses
rim 11. The hinge 30 may be disposed at the end of the main body
121 of the glasses temple away from the glasses rim 11 via the
portion of the main body 121 of the glasses temple.
[0046] Specifically, the rod-shaped member 40 may be provided with
a hinge chamber 41 connected to an end surface of the rod-shaped
member 40 along the length direction. A side wall of the rod-shaped
member 40 may be provided with a first insertion hole 42
communicating with the hinge chamber 41. The end of the hinge mount
31 away from the hinge arm 32 may be inserted into the hinge
chamber 41 from the end surface of the rod-shaped member 40, and
fixed in the hinge chamber 41 via a fixing member 50 inserted in
the first insertion hole 42.
[0047] In the embodiment, the hinge chamber 41 may communicate with
the end surface of the main body 121 of the glasses temple away
from the end of the glasses rim 11. Therefore, the hinge mount 31
is inserted into the hinge chamber 41 and the hinge 30 is connected
to the main body 121 of the glasses temple.
[0048] In some embodiments, the hinge chamber 41 may be formed
during a molding process of the rod-shaped member 40. For example,
the material of the rod-shaped member 40 may be rubber or plastic.
At this time, the hinge chamber 41 may be formed by injection
molding. The shape of the hinge chamber 41 may match the hinge
mount 31 so that the hinge mount 31 may be accommodated inside the
hinge chamber 41. In the embodiment, the main body 121 of the
glasses temple may have the shape of a long straight rod along the
length direction. Correspondingly, the rod-shaped member 40 may be
a straight rod along the length direction, and the hinge chamber 41
may be disposed inside the straight rod. Further, the hinge mount
31 may match the hinge chamber 41 to be accommodated inside the
hinge chamber 41 to implement the installation of the hinge 30. Of
course, in other embodiments, the rod-shaped member 40 may also
have other shapes such as an arc-shaped rod.
[0049] In addition, the first insertion hole 42 may be formed
during the molding process of the rod-shaped member 40, or may be
further formed on a side wall of the rod-shaped member by a manner
such as drilling after the molding process. Specifically, in the
embodiment, the shape of the first insertion hole 42 may be a
circle, and may be other shapes such as a square or a triangle in
other embodiments. The shape of the fixing member 50 may match the
first insertion hole 42 so that the fixing member 50 may be
inserted into the first insertion hole 42 from the outside of the
rod 40. Further, the hinge mount 31 may be fixed inside the hinge
chamber 41 by abutting the side wall of the hinge mount 31 or
further penetrating the outer wall of the hinge mount 31 in a
plugging manner. Specifically, a matching thread may be provided on
the inner wall of the first insertion hole 42 and the outer wall of
the fixing member 50. Therefore, the fixing member 50 may be
connected to the first insertion hole 42 in a screwing manner to
further fix the hinge mount 31 inside the hinge chamber 41. Of
course, other manners may also be used, such as connecting the
first insertion hole 42 and the fixing member 50 in an interference
fit manner.
[0050] Further, the hinge arm 32 may also be connected to other
components.
[0051] Therefore, after the other components are connected to the
hinge arm 32, the other components and the rod-shaped member 40 or
other components connected to the rod-shaped member 40 may further
rotate around the rotating shaft 33 by mounting the hinge mount 31
inside the hinge chamber 41. For example, when the hinge component
122 is used in the glasses, the function member 20 (e.g., the
speaker 21) may be connected to the end of the hinge arm 32 away
from the hinge mount 31. Therefore, the function member 20 may be
connected to the end of the main body 121 of the glasses temple
away from the glasses rim 11 via the hinge 30.
[0052] In the above manner, the rod-shaped member 40 may be
provided with the hinge chamber 41 communicating with the end
surface of the rod-shaped member 40. The hinge 30 may be
accommodated inside the hinge chamber 41 via the hinge mount 31.
The fixing member 50 may further penetrate the side wall of the rod
40 via the first insertion hole 42. Therefore, the hinge mount 31
accommodated inside the hinge chamber 41 may be fixed inside the
hinge chamber 41. Therefore, the hinge 30 may be detached relative
to the rod-shaped member 40 to facilitate the replacement of the
hinge 30 or the rod-shaped member 40. When applied to the glasses
in the embodiment of the present disclosure described above, the
hinge 30 and the function member 20 may be detachable relative to
the main body 121 of the glasses temple. Therefore, it may be easy
to replace when the function member 20, the glasses rim 11, or the
main body 121 of the glasses temple is damaged.
[0053] Further referring to FIG. 3, in one embodiment, the hinge
mount 31 may be provided with a second insertion hole 311
corresponding to the first insertion hole 42. The fixing member 50
may be further inserted into the second insertion hole 311.
[0054] Specifically, the shape of the second insertion hole 311 may
match the fixing member 50, so that the fixing member 50 may be
further inserted into the second insertion hole 311 to fix the
hinge mount 31 after passing through the first insertion hole 42.
Therefore, the shaking of the hinge mount 31 inside the hinge
chamber 41 may be reduced and the hinge 30 may be fixed more
firmly. Specifically, similar to the connection manner of the first
insertion hole 42 and the fixing member 50, the inner wall of the
second insertion hole 311 may be provided with a matching thread
corresponding to the outer wall of the fixing member 50. Therefore,
the fixing member 50 and the hinge mount 31 may be screwed
together. Alternatively, the inner wall of the second insertion
hole 311 and the outer wall of a corresponding contact position of
the fixing member 50 may be smooth surfaces. Therefore, the fixing
member 50 and the second insertion hole 311 may be in an
interference fit, and be not specifically limited herein.
[0055] Further, the second insertion hole 311 may penetrate both
sides of the hinge mount 31, so that the fixing member 50 may
further penetrate the entire hinge mount 31. The hinge mount 31 may
be more firmly fixed inside the hinge chamber 41.
[0056] Further referring to FIG. 4, FIG. 4 is a sectional view of
the hinge component 122 in FIG. 2 along an A-A axis according to
some embodiments of the present disclosure. In the embodiment, a
cross-sectional shape of the hinge mount 31 may match a
cross-sectional shape of the hinge chamber 41 in a section
perpendicular to the longitudinal direction of the rod-shaped
member 40. Therefore, the hinge mount 31 and the rod-shaped member
40 may form a tight fit after the insertion.
[0057] In some embodiments, the cross-sectional shape of the hinge
mount 31 and the cross-sectional shape of the hinge chamber 41 may
include any shape in the section shown in FIG. 4, as long as the
hinge mount 31 is inserted into the hinge chamber 41 from an end
surface of the rod-shaped member 40 away from the hinge arm 32.
Further, the first insertion hole 42 may be disposed on a side wall
of the hinge chamber 41, and pass through the side wall of the
hinge chamber 41 and communicate with the hinge chamber 41.
[0058] In an application scenario, the cross-sectional shape of the
hinge mount 31 and the cross-sectional shape of the hinge chamber
41 may have a rectangular shape. The first insertion hole 42 may be
perpendicular to one side of the rectangle.
[0059] Specifically, in the application scenario, a corner angle of
the outer wall of the hinge mount 31 or an angle of the inner wall
of the hinge chamber 41 may be further in a fillet set to make
contact between the hinge mount 31 and the hinge chamber 41
smoother. Therefore, the hinge mount 31 may be smoothly inserted
into the hinge chamber 41.
[0060] It should be further pointed out that an amount of gas may
be stored in the hinge chamber 41 before the hinge 30 is assembled.
Therefore, if the hinge chamber 41 is a chamber with an open at
only one end, the assembly of the hinge mount 31 may not be
facilitated due to the difficulty in exhausting the gas inside the
hinge chamber 41 during the assembly process. In the embodiment,
the first insertion hole 42 may penetrate the side wall of the
hinge chamber 41 and communicate with the hinge chamber 41 which
may assist in exhausting the inner gas from the first insertion
hole 42 through the hinge chamber 41 during the assembly, thereby
facilitating the normal assembly of the hinge 30.
[0061] Further referring to FIG. 5, FIG. 5 is a schematic
structural diagram illustrating a hinge component according to an
embodiment of the present disclosure. In the embodiment of the
present disclosure, the hinge component 122 may further include a
connection wire 60 disposed outside the hinge 30.
[0062] In some embodiments, the connection wire 60 may be a
connection wire 60 having an electrical connection function and/or
a mechanical connection function. When applied to the glasses in
the embodiment of the present disclosure described above, the hinge
component 122 may be used to connect the function member 20 to the
end of the main body 121 of the glasses temple away from the
glasses rim 11. A control circuit and the like related to the
function member 20 may be disposed on the main body 121 of the
glasses temple. At this time, the connection wire 60 may be
required to electrically connect the function member 20 to the
control circuit and the like of the main body 121 of the glasses
temple. Specifically, the connection wire 60 may be located at one
side of the hinge mount 31 and the hinge arm 32, and disposed in
the same accommodation space with the hinge 30.
[0063] Further, the hinge mount 31 may include a first end surface
312. The hinge arm 32 may have a second end surface 321 disposed
opposite the first end surface 312. It is easily understood that
there is a gap between the first end surface 312 and the second end
surface 321. Therefore, the hinge mount 31 and the hinge arm 32 may
be relatively rotated around the rotating shaft 33. In the
embodiment, during the relative rotation of the hinge arm 32 and
the hinge mount 31, relative positions between the first end
surface 312 and the second end surface 321 may also change.
Therefore, the gap between thereof may become larger or
smaller.
[0064] In the embodiment, the gap between the first end surface 312
and the second end surface 321 may always be kept larger than or
less than the diameter of the connection wire 60. Therefore, the
connection wire 60 located outside the hinge 30 may not be inserted
into the gap between the first end surface 312 and the second end
surface 321 during the relative rotation of the hinge mount 31 and
the hinge arm 32, thereby reducing the damage to the connection
wire 60 by the hinge. Specifically, during the relative rotation of
the hinge arm 32 and the hinge mount 31, the ratio of the gap
between the first end surface 312 and the second end surface 321 to
the diameter of the connection wire 60 may always be kept greater
than 1.5 or less than 0.8, for example, greater than 1.5, 1.7, 1.9,
2.0, etc., or less than 0.8, 0.6, 0.4, 0.2, etc., and be not
specifically limited herein.
[0065] Further referring to FIG. 2, and FIG. 6 to FIG. 9, FIG. 6 is
a diagram illustrating an original state of a protective sleeve of
a hinge component according to one embodiment of the present
disclosure. FIG. 7 is a partial sectional view illustrating an
original state of a protective sleeve of a hinge component
according to an embodiment of the present disclosure. FIG. 8 is a
diagram illustrating a bent state of a protective sleeve of a hinge
component according to an embodiment of the present disclosure.
FIG. 9 is a partial sectional view illustrating a folded state of a
protective sleeve of a hinge component according to one embodiment
of the present disclosure. In the embodiment, the hinge component
122 may also include a protective sleeve 70.
[0066] Specifically, the protective sleeve 70 may be disposed on
the periphery of the hinge 30 and bent along with the hinge 30. In
some embodiments, the protective sleeve 70 may include a plurality
of annular ridge portions 71 spaced apart along the length
direction of the protective sleeve 70 and annular connection
portions 72 disposed between the annular ridge portions 71 and used
to connect each two adjacent annular ridge portions. In some
embodiments, the tube wall thickness of the annular ridge portion
71 may be greater than the tube wall thickness of the annular
connection portion 72.
[0067] In some embodiments, the length direction of the protection
sleeve 70 may be consistent with the length direction of the hinge
30. The protection sleeve 70 may be disposed along the length
direction of the hinge mount 31 and the hinge arm 32. The
protective sleeve 70 may be made of a soft material, such as soft
silicone, rubber, etc.
[0068] The outer sidewall of the protective sleeve 70 may protrude
outwardly to form the annular ridge portion 71. The shape of the
inner sidewall of the protective sleeve 70 corresponding to the
annular ridge portion 71 may not be specifically limited herein.
For example, the inner wall may be smooth, or a recession may be
disposed on the position of the inner wall corresponding to the
annular ridge portion 71.
[0069] The annular connection portion 72 may be used to connect the
adjacent annular ridge portions 71, specifically connected to an
edge region of the annular ridge portion 71 near the inside of the
protective sleeve 70. Therefore, the annular connection portion 72
may recess relative to the annular ridge portion 71 at a side of
the outer wall of the protective sleeve 70.
[0070] Specifically, the count of the annular ridge portions 71 and
the count of the annular connection portions 72 may be determined
according to actual use conditions, for example, according to the
length of the protective sleeve 70, the width of the annular ridge
71 and the width of the annular connection portion 72 in the
longitudinal direction of the protective sleeve 70, or the
like.
[0071] Further, the tube wall thickness of the annular ridge
portion 71 and the tube wall thickness of the annular connection
portion 72 refer to the thickness between the inner wall and the
outer wall of the protective sleeve 70 corresponding to the annular
ridge portion 71 and the annular connection portion 72,
respectively. In the embodiment, the tube wall thickness of the
annular ridge portion 71 may be greater than the tube wall
thickness of the annular connection portion 72.
[0072] It should be easily understood when the hinge mount 31 and
the hinge arm 32 of the hinge 30 are relatively rotated around the
rotating shaft 33, the angle between the hinge mount 31 and the
hinge arm 32 may change so that the protective sleeve 70 is bent as
shown in FIGS. 8 and 9. Specifically, when the protective sleeve 70
is bent with the hinge 30, the annular ridge portion 71 and the
annular connection portion 72 located in an outer region of the
bent shape formed by the protective sleeve 70 may be in a stretched
state, while the annular ridge portion 71 and the annular
connection portion 72 located in an inner region of the bent shape
may be in a compressed state.
[0073] In the embodiment, the tube wall thickness of the annular
ridge portion 71 may be greater than the tube wall thickness of the
annular connection portion 72. Therefore, the annular ridge portion
71 may be more rigid than the annular connection portion 72.
Therefore, when the protective sleeve 70 is in the bent state, the
protective sleeve 70 at the outer side of the bent shape may be in
the stretched state. The annular ridge portion 71 may provide a
strength support for the protective sleeve 70. At the same time, a
region of the protective sleeve 70 at the inner side in the bent
state may be compressed. The annular ridge portion 71 may also
withstand a compression force, thereby protecting the protective
sleeve 70, improving the stability of the protective sleeve 70, and
extending the life of the protective sleeve 70.
[0074] Further, it should be noted that the shape of the protective
sleeve 70 may be consistent with the state of the hinge 30. In one
application scenario, both sides of the protective sleeve 70 along
the length direction and rotating around the rotating shaft may be
stretched or compressed. In another application scenario, the hinge
mount 31 and the hinge arm 32 of the hinge 30 may rotate around the
rotating shaft 33 only within a range less than or equal to 180
degree. That is, the protective sleeve 70 may only be bent toward
one side. One side of the two sides of the protective sleeve 70 in
the length direction may be compressed, and the other side may be
stretched. At this time, according to different forces on the two
sides of the protective sleeve 70, the two sides of the protective
sleeve 70 under the different forces may have different
structures.
[0075] In one embodiment, when the protective sleeve 70 is in the
bent state, the width of the annular ridge portion 71 along the
longitudinal direction of the protective sleeve 70 toward the outer
side of the bent shape formed by the protective sleeve 70 may be
greater than the width along the length of the protective sleeve 70
towards the inside of the bent shape.
[0076] In some embodiments, an increment of the width of the
annular ridge portion 71 along the length direction of the
protective sleeve 70 may further increase the strength of the
protective sleeve. Meanwhile, in the embodiment, an original
included angle between the hinge mount 31 and the hinge arm 32 may
be less than 180 degree. At this time, if the annular ridge
portions 71 of the protective sleeve 70 are uniformly disposed, the
protective sleeve 70 may be compressed in the original state. In
the embodiment, the width of the annular ridge portion 71
corresponding to one side of the outer region of the bent shape in
the bent state may be relatively large, so that the length of the
side of the protective sleeve 70 may increase. Therefore, during
the increment of the strength of the protective sleeve 70, a
stretching degree of the stretching side may be reduced when the
protective sleeve 70 is bent. At the same time, the width of the
annular ridge portion 71 along the longitudinal direction of the
protective sleeve 70 toward the side of the inner region of the
bent shape may be relatively small when the protective sleeve 70 is
in the bent state, which may increase a space of the compressed
annular connection portion 72 in the length direction of the
protective sleeve 70, and alleviate the compression of the
compressed side.
[0077] Further, in an application scenario, the width of the
annular ridge portion 71 may gradually decrease from the side of
the outer region towards the bent shape to the side of the inner
region towards the bent shape. Therefore, the width toward the side
of the outer region of the bent shape formed by the protective
sleeve 70 may be greater than the width toward the side of the
inner region of the bent shape when the protective sleeve 70 is in
the bent state.
[0078] It should be easily understood that the annular ridge
portions 71 are disposed around the periphery of the protective
sleeve 70. In the length direction of the protective sleeve 70, one
side may correspond to the stretched side, and the other side may
correspond to the compressed side. In the embodiment, the width of
the annular ridge portion 71 may gradually decrease from the side
of the outer region towards the bent shape to the side of the inner
region towards the bent shape, so that the width may be more
uniform, which may improve the stability of the protective sleeve
70.
[0079] In one embodiment, the annular ridge portion 71 may be
disposed with a groove 711 on an inner ring surface inside the
protective sleeve 70 at the side of the outer region of the bent
shape formed by the protective sleeve 70 when the protective sleeve
70 is in the bent state.
[0080] Specifically, the groove 711 in the embodiment may be
disposed along a direction perpendicular to the length direction of
the protective sleeve 70. Therefore, the corresponding annular
ridge portion 71 may be appropriately extended in the length
direction when the protective sleeve 70 is stretched.
[0081] As described above, when the protective sleeve 70 is in the
bent state, the protective sleeve 70 towards the outer side of the
bent shape formed by the protective sleeve 70 may be in the
stretched state. In the embodiment, the groove 711 may be further
disposed on the inner ring surface inside the protective sleeve 70
corresponding to the corresponding annular ridge portion 71,
Therefore, the annular ridge portion 71 corresponding to the groove
711 may be appropriately extended to bear a portion of the stretch
when the protective sleeve is stretched at the side, thereby
reducing a tensile force experienced by the protective sleeve at
the side, and protecting the protective sleeve 70.
[0082] It should be noted that the inner wall of the protective
sleeve 70 corresponding to the annular ridge portion 71 at the side
towards the inner region of the bent shape may not be disposed with
the groove 711 when the protective sleeve 70 is in the bent state.
In an embodiment, the width of the groove 71 along the length of
the protective sleeve 70 may gradually decrease from the side of
the outer region towards the bent shape to the side of the inner
region towards the bent shape. Therefore, no groove 711 may be
disposed on the inner side wall of the protective sleeve 70
corresponding to the annular ridge portion 71 towards the inner
region side of the bent shape.
[0083] Specifically, when the hinge component 122 in the embodiment
is applied to the glasses in the embodiment of the present
disclosure described above, the protective sleeve 70 may be
disposed on the main bodies 121 of the glasses temples at both
sides in the length direction of the protective sleeve 70,
respectively, and connected to the function member 20. In an
application scenario, the protective sleeve 70 may also be
integrally formed as other structures of the glasses, such as
protective covers of some components, so that the glasses may be
more sealed and integrated.
[0084] It should be noted that the hinge component 122 in the
embodiment of the present disclosure may not only be used in the
glasses in the embodiment of the present disclosure, but also be
used in other devices. Moreover, the hinge component 122 may also
include other components related to the hinge 30 other than the
rod-shaped member 40, the fixing member 50, the connection wire 60,
the protective sleeve 70, etc. to achieve corresponding
functions.
[0085] Specifically, referring to FIG. 10 to FIG. 14 together, FIG.
10 is a partial sectional view illustrating a hinge according to an
embodiment of the present disclosure. FIG. 11 is an enlarged view
illustrating part A in FIG. 10 according to some embodiments of the
present disclosure. FIG. 12 is an enlarged view illustrating part B
in FIG. 11 according to some embodiments of the present disclosure.
Specifically, FIG. 12 shows an enlarged view illustrating part B in
FIG. 11 when the abutting between a first support surface and a
third support surface is changed to the abutting between a second
support surface and the third support surface, Therefore, a
connection between the first support surface and the second support
surface initially touches the third support surface. FIG. 13 is a
partial sectional view illustrating a hinge according to an
embodiment of the present disclosure. FIG. 14 is an enlarged view
illustrating part C in FIG. 13 according to some embodiments of the
present disclosure. It should be noted that the hinge 30 in the
embodiment of the present disclosure may be used in the glasses in
the embodiment of the present disclosure. The hinge 30 may be used
in the hinge component 122 in the embodiments of the present
disclosure, or used in other devices, and be not specifically
limited herein.
[0086] In the embodiment, the hinge arm 32 of the hinge 30 may have
a first support surface 322 and a second support surface 323
connected to each other.
[0087] The hinge 30 may also include a support member 34 and an
elastic member 35. The support member 34 may be flexibly disposed
on the hinge mount 31 and have a third support surface 341. The
elastic member 35 may be used to elastically offset the support
member 34 toward the hinge arm 32, so that the third support
surface 341 may elastically abut on the first support surface 322
and the second support surface 323, respectively.
[0088] In some embodiments, when the hinge arm 32 is rotated
relative to the hinge mount 31 under an external force, a
connection 324 of the first support surface 322 and the second
support surface 323 may drive the support member 34 against the
elastic offset of the elastic member 35 to move in the opposite
direction. Therefore, the third support surface 341 may be switched
from elastically abutting on one of the first support surface 322
and the second support surface 323 to elastically abutting on the
other of the first support surface 322 and the second support
surface 323.
[0089] In an application scenario, the support member 34 may be
connected to an end of the elastic member 35 towards the hinge arm
32. The third support surface 341 may face the side toward the
hinge arm 32. In the process that the hinge arm 32 is rotated
relative to the hinge mount 31 around the rotating shaft 33 under
the external force, the third support surface 341 may be pushed so
that the support member 34 may compress the elastic member 35.
Further, the elastic offset may occur under the action of the
elastic member 35. Of course, the elastic member 35 may be
disconnected to the support member 34, and only abut on one side of
the support member 34 as long as the support member 34 implements
the elastic offset.
[0090] In some embodiments, the first support surface 322 and the
second support surface 323 may be two side surfaces adjacent to the
hinge arm 32 and at least partially parallel to the central axis of
the rotating shaft 33, or a portion of the two side surfaces. When
the hinge arm 32 rotates relative to the hinge mount 31, the first
support surface 322 and the second support surface 323 may rotate
with the hinge arm 32 around the rotating shaft 33. Therefore,
different side surfaces of the hinge arm 32 may face the hinge
mount 31. Thus, the hinge arm 32 may have different positions
relative to the hinge mount 31.
[0091] In addition, the elastic member 35 may be a member that may
provide an elastic force and be compressed in an elastic direction
to provide a compression space. For example, the elastic member 35
may include a spring. One end of the spring may abut on the support
member 34. When the third support surface 341 of support member 34
is pushed toward the elastic member 35, the elastic member 35 may
be against the support member 34 and be compressed to provide a
space in a direction that the third support surface 341 of the
support member 34 faces. Therefore, when a relative position of the
rotating shaft 33 is unchanged, there may be still enough space for
different sides of the hinge arm 32 to rotate between the rotating
shaft 33 and the third support surface 341.
[0092] Specifically, when the hinge arm 32 rotates relative to the
hinge mount 31, the relative position of the rotating shaft 33 may
be unchanged, A contact position of the hinge arm 32 and the third
support surface 341 of the hinge mount 31 may change. Since
distances between different positions of the hinge arm 32 and the
rotating shaft 33 are different, the required space between the
rotating shaft 33 and the contact position of the hinge arm 32 and
the third support surface 341 may be different when different
positions of the hinge arm 32 (e.g., different positions of the
first support surface 322 and the second support surface 323)
contact the third support surface 341. Due to the limitation of the
elastic force and the space, the space provided by the compression
of the elastic member 35 may be limited. Therefore, during the
rotation of the hinge arm 32 relative to the hinge mount 31, if a
distance between a position of the hinge arm 32 and the rotating
shaft 33 is too large in a section perpendicular to the central
axis of the rotating shaft 33, the position may be locked at
another position of the third support surface during the rotation
process, so that the hinge arm 32 may not continue to rotate.
Therefore, the hinge arm 32 and the hinge mount 31 only rotates
relatively within a range. In an application scenario, during the
relative rotation between the hinge arm 32 and the hinge mount 31
around the rotating shaft 33, only the first support surface 322,
the second support surface 323, and a region corresponding to the
connection 324 between the first support surface 322 and the second
support surface 323 may abut on the third support surface 341.
[0093] Further, in the embodiment, the first support surface 322
and the second support surface 323 may both be planes. A distance
from the rotating shaft 33 to the connection 324 of the two support
surfaces may be greater than a distance from the rotating shaft 33
to the first support surface 322 and a distance to the second
support surface 323. The hinge 30 may have two relatively stable
states that the third support surface 341 abuts on the first
support surface 322 and the third support surface 341 abuts on the
second support surface 323.
[0094] Of course, in the embodiment, the first support surface 322
and the second support surface 323 may also be curved surfaces with
a radian or even include different sub-support surfaces, as long as
a positional relationship between the hinge arm 32 and the hinge
mount 31 may have at least two corresponding relatively stable
states, and be not specifically limited herein. In addition, the
hinge arm 32 may be disposed with more support surfaces. The hinge
arm 32 and the hinge mount 31 may have various relative positional
relationships by the different support surfaces elastically
abutting on the third support surface 341 when the hinge arm 32
rotates relative to the hinge mount 31 around the rotating shaft 33
under an external force, and be not specifically limited
herein.
[0095] Specifically, as shown in FIG. 11 and FIG. 12, an original
state that the first support surface 322 abuts on the third support
surface 341 of the support member 34 may be taken as an example. At
this time, the elastic member 35 may have an elastic compression
deformation, or be in an original natural state, and be not limited
herein. When the hinge arm 32 rotates relative to the hinge mount
31 around the rotating shaft 33 under an external force of the
hinge 30. Therefore, the second support surface 323 gradually
approaches the third support surface 341, the connection 324
between the first support surface 322 and the second support
surface 323 may touch the third support surface 341. Since the
distance from the connection 324 to the rotating shaft 33 may be
greater than the distance from the first support surface 322 to the
rotating shaft 33, the connection 324 may abut on the support
member 34 and push the support member 34 move toward the elastic
member 35, thereby allowing the elastic member 35 against the pull
to compress. When the hinge arm 32 is further stressed, the
connection 324 may gradually approach a region between the rotating
shaft 33 and the third support surface 341. In the process, the
distance between the rotating shaft 33 and the third support
surface 341 may gradually increase. It should be easily understood
when a connection line between the connection 324 and the rotating
shaft 33 is perpendicular to the third support surface 341, the
distance from the rotating shaft 33 to the third support surface
341 may be equal to the distance from the rotating shaft 33 to the
connection 324 in a section perpendicular to the central axis of
the rotating shaft 33. At this time, the rotating shaft 33 may be
farthest from the third support surface 341. At this time, if the
force is continuously applied to the hinge 30, the distance from
the rotating shaft 33 to the third support surface 341 may
gradually become smaller, so that the required compression space of
the elastic member 35 may be reduced. Then the elastic member 35
may gradually release the elastic force and recover until the
connection 324 leaves the third support surface 341 and the second
support surface 323 abuts on the third support surface 341, thereby
switching from abutting the first support surface 322 on the third
support surface 341 to abutting the second support surface 323 on
the third support surface 341.
[0096] Similarly, the process (as shown in FIG. 13 and FIG. 14) for
switching from an original state that the second support surface
323 abuts on the third support surface 341 of the support member 34
to a state that the first support surface 322 abuts on the third
support surface 341 of the support member 34 may be similar to the
above process.
[0097] It should be noted that the hinge 30 in the embodiment may
be applied to the hinge component 122 of the glasses in the
embodiment of the present disclosure. When the third support
surface 341 is switched from elastically abutting on one of the
first support surface 322 and the second support surface 323 to
elastically abutting on the other of the first support surface 322
and the second support surface 323, the hinge component 122 may
drive the speaker 21 to switch between a first relatively fixing
position and a second relatively fixing position relative to the
main body 121 of the glasses temple. The hinge component 122 may
fit on the back of an auricle of the user when the speaker 21 is in
the first relatively fixing position. As used herein, the auricle
may be a portion of an external ear and mainly composed of
cartilage. In some embodiments, the speaker 21 may include a bone
conduction speaker. By fitting the speaker to the back of the
auricle, the cartilage of the auricle may be used to transmit bone
conduction sound/vibration. The bone conduction speaker may be
fitted to the back of the auricle, thereby improving the sound
quality and reducing the impact on an ear canal during the sound
transmission.
[0098] It should be noted that the distance from the rotating shaft
33 to the connection 324 may be greater than a vertical distance
from the first support surface 322 and the second support surface
323. Therefore, in the process that the third support surface 341
is switched from elastically abutting on one of the first support
surface 322 and the second support surface 323 to elastically
abutting on the other of the first support surface 322 and the
second support surface 323, the state of the hinge 30 may change
abruptly.
[0099] The switch from elastically abutting between the first
support surface 322 and the third support surface 341 to
elastically abutting between the second support surface 323 and the
third support surface 341 may be taken as an example. When a ratio
between the maximum distance h.sub.1 from the rotating shaft 33 to
the connection 324 and the shortest distance h.sub.2 from the
rotating shaft 33 to the first support surface 322 is different,
the change during the switching process may be different.
[0100] In one embodiment, the ratio between the maximum distance h1
from the rotating shaft 33 to the connection 324 and the shortest
distance h.sub.2 from the rotating shaft 33 to the first support
surface 322 may be between 1.1 and 1.5 in the section perpendicular
to the central axis of the rotating shaft 33.
[0101] Specifically, the maximum distance h.sub.1 from the rotating
shaft 33 to the connection 324 may be larger than the shortest
distance h.sub.2 of the rotating shaft 33 to the first support
surface 322 by disposing the rotating shaft 33 away from the second
support surface 323 and close to the side of the hinge arm 32
opposite to the second support surface 323, thereby satisfying the
ratio described above.
[0102] It should be noted that the change may become obvious when
the ratio between h.sub.1 and h.sub.2 is too large. However, a
large force may be needed to switch from elastically abutting
between the first support surface 322 and the third support surface
341 to elastically abutting between the second support surface 323
and the third support surface 341, thereby causing inconvenience.
If the ratio between h.sub.1 and h.sub.2 is too small, although it
is easier to switch the state, the change may be small. For
example, when the user pulls the hinge 30, there may be no obvious
handle sense, causing inconvenience. In the embodiment, the ratio
of h.sub.1 to h.sub.2 may be set between 1.1 and 1.5, and the hinge
30 may have a more obvious change when the third support surface
341 is switched from elastically abutting on the first support
surface 322 to elastically abutting on the second support surface
323. Thus, during use, the user may have a relatively obvious
handle sense of pulling the hinge 30. At the same time, the change
may not be too abrupt to making it difficult for the user to switch
the state of the hinge 30.
[0103] In an application scenario, the ratio of h.sub.1 to h.sub.2
may also be between 1.2 and 1.4. Specifically, the ratio of h.sub.1
to h.sub.2 may also be 1.1, 1.2, 1.3, 1.4, 1.5, etc., and be not
specifically limited herein.
[0104] In addition, the positions of the first support surface 322
and the second support surface 323 set on the hinge arm 32 may
affect the included angle between the hinge arm 32 and the hinge
mount 31 when the third support surface 341 abuts on one of the
first support surface 322 and the second support surface 323.
Therefore, the positions of the first support surface 322 and the
second support surface 323 on the hinge arm 32 may be set
differently according to specific user requirements. In some
embodiments, the included angle between the hinge arm 32 and the
hinge mount 31 may be specifically shown in FIG. 9 and FIG. 12.
.omega.1 may be the included angle between the hinge arm 32 and the
hinge mount 31 when the third support surface 341 abuts on the
first support surface 322. .omega.2 may be the included angle
between the hinge arm 32 and the hinge mount 31 when the third
support surface 341 abuts on the second support surface 323, In one
embodiment, each of the hinge arm 32 and the hinge mount 31 may
have a length. The hinge arm 32 may be disposed on one end side of
the hinge mount 31 in the length direction. The first support
surface 322 may be disposed at the end of the hinge arm 32 near the
hinge mount 31 in the length direction. The second support surface
323 may be disposed at one end in the width direction of the hinge
arm 32 and parallel to the central axis of the rotating shaft 33.
At this time, when the third support surface 341 elastically abuts
on the first support surface 322, the included angle between the
hinge arm 32 and the hinge mount 31 may be the largest. When the
third support surface 341 elastically abuts on the second support
surface 323, the included angle between the hinge arm 32 and the
hinge mount 31 may be the smallest. Therefore, the included angle
between the hinge mount 31 and the hinge arm 32 may be changed from
.omega.1 to .omega.2 and become smaller when the third support
surface 341 is switched from elastically abutting on the first
support surface 322 to elastically abutting on the second support
surface 323.
[0105] It should to be further noted if the direction of the force
applied to the hinge arm 32 is the same as the direction of the
gravity of the hinge arm 32 when the third support surface 341 is
switched from elastically abutting on the first support surface 322
to elastically abutting on the second support surface 323, the
switching in this state may make the included angle between the
hinge mount 31 and the hinge arm 32 smaller. The setting of the
ratio between the h.sub.1 and h.sub.2 in the embodiment may also
make the hinge arm 32 not or hardly reduce the angle between the
hinge arm 32 and the hinge mount 31 spontaneously due to the own
gravity when the third support surface 341 elastically abut on the
first support surface 322.
[0106] In an embodiment of a hinge in the present disclosure,
referring to FIG. 12, the included angle .omega..sub.3 between the
first support surface 322 and the second support surface 323 may be
an obtuse angle in a section perpendicular to the central axis of
the rotating shaft 33.
[0107] In some embodiments, when the hinge 30 switches from the
state of elastically abutting between the first support surface 322
and the third support surface 341 to the state of elastically
abutting between the second support surface 323 and the third
support surface 341, the smaller the included angle .omega..sub.3
between the first support surface 322 and the second support
surface 323, the larger the relative rotation angle between the
hinge mount 31 and the hinge arm 32 may be when the state is
switched. That is, when the hinge mount 31 is fixed, the user may
need to move the hinge arm 32 to a larger angle to switch the state
of the hinge 30, so that the user may be laborious and it may bring
inconvenience to the user.
[0108] Since the hinge arm 32 has a length, and the first support
surface 322 is disposed at one end in the length direction of the
hinge arm 32, the second support surface 323 may be disposed
adjacent to the first support surface 322 in the width direction of
the hinge arm 32, Normally, the first support surface 322 and the
second support surface 323 may be arranged vertically. At this
time, when the hinge 30 is switched between the two states, the
hinge arm 32 and the hinge mount 31 may need to be moved relative
to each other by 90 degree.
[0109] In the embodiment, in the section perpendicular to the
central axis of the rotating shaft 33, the included angle
.omega..sub.3 between the first support surface 322 and the second
support surface 323 may be an obtuse angle. Thus, the angle
required for the relative movement of the hinge arm 32 and the
hinge mount 31 may be less than 90 degree when the hinge 30
switches between the two states, which may facilitate the user.
[0110] Specifically, when the hinge 30 in the embodiment is used in
the embodiment of the glasses in the present disclosure, the hinge
30 may be used to connect the main body 121 of the glasses temple
and the speaker 21. In some embodiments, the speaker 21 may be a
bone conduction speaker. For example, when the hinge 30 is in a
second state of elastically abutting between the second support
surface 323 and the third support surface 341, the speaker 21 may
be in the first relatively fixing position to fit the back of the
auricle of the user. Therefore, when the user needs to use the
function of the speaker 21 of the glasses, the user may only need
to rotate the speaker 21 by an angle less than 90 degree to fit it
to the back of the auricle of the user. In addition, when the hinge
30 is in a first state of elastically abutting between the first
support surface 322 and the third support surface 341, the hinge
arm 32 and the connected speaker 21 may form an angle. Therefore,
the hinge arm 32 and the connected speaker 21 may be located behind
an ear of the user and face the direction of the ear of the user
when the user wears the glasses. Therefore, the glasses may be
blocked and fixed, and prevented from falling off the head of the
user.
[0111] It should be noted that the included angle .omega..sub.3
between the first support surface 322 and the second support
surface 323 may be set according to actual requirements. If the
included angle is too large, the included angle between the hinge
arm 32 and the hinge mount 31 and the angle between the function
member 20 connected to the end of the hinge arm 32 away from the
hinge mount 31 and the hinge mount 31 may be smaller. Therefore,
the hinge arm 32 and the function member 20 may be too close to the
ears of the user to compress the ears when the user wears it,
reducing the comfort of the user. If the included angle is too
small, on the one hand, the required angle may be too large, which
is inconvenient for the user when the user moves the speaker 21 to
switch between the first relative position and the second relative
position. On the other hand, the included angle between the main
body 121 of the glasses temple and the hinge 30 and the included
angle between the main body 121 of the glasses temple and the
speaker 21 may be too small to play a role in blocking and fixing
the glasses. Therefore, the glasses may be easily dropped from the
front side of the head of the user when the user wears the glasses.
Specifically, the included angle between the first support surface
322 and the second support surface 323 may be set according to the
shape of the head of the user.
[0112] Specifically, in an application scenario, in the section
perpendicular to the central axis of the rotating shaft 33, the
included angle .omega..sub.3 between the first support surface 322
and the second support surface 323 may be between 100 degree and
120 degree, and specifically be 100 degree, 110 degree, 120 degree,
or the like. The setting of the angle may enable the user to wear
the glasses, and the speaker 21 may not be too close to the ears of
the user to cause discomfort to the ears of the user when the
speaker 21 is in the first relatively fixing position. It may be
unnecessary to rotate the hinge by an excessive angle upon
switching between the two relative positions of the speaker 21,
which is convenient for users.
[0113] In some embodiments, in the process that the third support
surface 341 is switched from elastically abutting on one of the
first support surface 322 and the second support surface 323 to
elastically abutting on the other of the first support surface 322
and the second support surface 323, the connection 324 between the
first support surface 322 and the second support surface 323 may
abut on the third support surface 341, and drive the support member
34 against the elastic offset of the elastic member 35 to move in
the opposite direction. Elastically abutting between the third
support surface 341 and the first support surface 322 before the
switching may be taken as an example. At the start of the
switching, while the first support surface 322 gradually moves away
from the third support surface 341, the connection 324 may
gradually abut on the third support surface 341 and slide from one
side of the third support surface 341 to another side of the third
support surface 341 during the switching process. Finally, the
second support surface 323 and the third support surface 341 may
further turn to elastically abut. During the state switching
process, the connection 324 may always abut on and interact with
the third support surface 341. The shape of the connection 324 may
have an effect on the state switching process. For example, if the
first support surface 322 and the second support surface 323 are
line-connected, the connection 324 may have a relatively sharp
angle. Therefore, during the user pulls the hinge mount 31 and/or
the hinge arm 32 to switch the state of the hinge 30, on the one
hand, the buffer may be small and the switching may be abrupt upon
switching from abutting between the connection 324 and the third
support surface 341 to abutting between the connection 324 and the
first support surface 322 and the second support surface 323. Thus
the handle sense of moving the hinge 30 may be poor. On the other
hand, the connection 324 may be relatively sharp, which may cause
wear to the third support surface 341 during repeated switching
processes.
[0114] In one embodiment of the present disclosure, in a section
perpendicular to the central axis of the rotating shaft 33, the
connection 324 may have a shape of an arc. As a result, the
connection between the first support surface 322 and the second
support surface 323 may be a connection with an arc surface. During
the state switching process of the hinge 30, the connection 324
abutting on the third support surface 341 may be relatively smooth,
so that the user may have a better handle sense of pulling the
hinge 30. The damage to the third support surface 341 may be
reduced during repeated switching processes.
[0115] Specifically, in one embodiment, the connection 324 may have
a shape of a circular arc. If a curvature of the arc is different,
effects brought by the curvatures may be different. The curvature
may be set in combination with actual use situations. The curvature
of the arc in the embodiment may be between 5 and 30, and
specifically 5, 10, 15, 20, 25, 30, etc., and be not limited
herein.
[0116] It should be noted when the hinge 30 in the embodiment is
applied to the glasses in the embodiment described above, the
circular arc shape of the curvature of the connection 324 may
enable the user to have a better feel when the hinge 30 is pulled
to drive the speaker to switch between the first relatively fixing
position and the second relatively fixing position.
[0117] In one embodiment, the third support surface 341 may be set
so that the external force required when the third support surface
341 is switched from elastically abutting on the first support
surface 322 to elastically abutting on the second support surface
323 may be different from the external force required when the
third support surface 341 is switched from elastically abutting on
the second support surface 323 to elastically abutting on the first
support surface 322.
[0118] It should be noted that, in a specific use scenario,
different states of the hinge 30 may correspond to different
functions of the hinge 30 or structures connected to the hinge 30.
Alternatively, due to a setting problem of the position of the
hinge 30, it may not be convenient for the user to exert a force to
switch from one state to another. When the user switches the state
of the hinge 30, it may be necessary to distinguish the strength of
pulling the hinge 30 to facilitate the user to exert the force, or
to provide the user with an intuitive experience to distinguish the
two hinge states.
[0119] Specifically, when the hinge 30 in the embodiment is applied
to the glasses, the state switching of the hinge 30 may drive the
speaker 21 to switch between the first relatively fixing position
and the second relatively fixing position relative to the main body
121 of the glasses temple. Correspondingly, the two relatively
fixing positions may correspond to two situations where the user
uses the speaker 21 and where the user does not use the speaker 21.
When the user wears the glasses, difficulty of applying forces to
the back of the head to switch between the two states may be
different. Therefore, the design of applying different external
forces to correspondingly switching between different states may
facilitate the usage of the user.
[0120] Specifically, in an embodiment, when the third support
surface 341 is switched from elastically abutting on the first
support surface 322 to elastically abutting on the second support
surface 323, the speaker 21 may move from the second relatively
fixing position to the first relatively fixing position so as to
fit the back of the auricle of the user.
[0121] Further, in the embodiment, the third support surface 341
may be set such that the external force required when the third
support surface 341 is switched from elastically abutting on the
first support surface 322 to elastically abutting on the second
support surface 323 may be less than the external force required
when the third support surface 341 is switched from elastically
abutting on the second support surface 323 to elastically abutting
on the first support surface 322.
[0122] It should be noted when the speaker 21 is used, the third
support surface 341 may need to be switched from elastically
abutting on the first support surface 322 to elastically abutting
on the second support surface 323 upon being applied to the
glasses. When the speaker 21 is not used, the third support surface
341 may need to be switched from elastically abutting on the second
support surface 323 to elastically abutting on the third support
surface 341. According to the embodiment, the force required when
the user uses the speaker 21 may be less than the force required
when the speaker 21 is not used. Therefore, it may be convenient
for the user to use the function of the speaker 21 of the
glasses.
[0123] Specifically, referring to FIG. 12 and FIG. 14 together, in
an application scenario, when the third support surface 341 is
switched from elastically abutting on the first support surface 322
to elastically abutting on the second support surface 323, the
connection 324 may initially contact a first position 3411 of the
third support surface 341. When the third support surface 341 is
switched from t elastically abutting on the second support surface
323 to elastically abutting on the first support surface 322, the
connection 324 may initially contact a second position 3412 of the
third support surface 341. In some embodiments, in a section
perpendicular to the central axis of the rotating shaft 33, a
distance d1 between the first position 3411 and a contact point of
the elastic member 35 and the support member 34 along the direction
of the elastic offset of the elastic member 35 may be less than a
distance d2 between the second position 3412 and the contact point
in the direction of the elastic offset.
[0124] It should be noted when the third support surface 341
elastically abuts on the first support surface 322, the connection
324 may be located near a position of one end of the third support
surface 341. When the third support surface 341 elastically abuts
on the second support surface 323, the connection 324 may be
located near a position of another end of the third support surface
341. Therefore, the first position 3411 and the second position
3412 may be located near the two ends of the third support surface
341, respectively. That is, in the embodiment, a distance between
the positions of the third support surface 341 of the support
member 34 near the two ends may be different from a distance
between the elastic member 35 and the contact point of the support
member 34 in the direction of the elastic offset of the elastic
member 35. The distance corresponding to the second position 3412
may be less than the distance corresponding to the first position
3411. At this time, when the third support surface 341 is switched
from elastically abutting on the first support surface 322 to
elastically abutting on the second support surface 323, the
connection 324 may not immediately abut on the third support
surface 341 and receive a reaction force of the elastic member 35,
but gradually abut on the third support surface 341 and receive the
reaction force of the elastic member 35 during the switching
process. When the third support surface 341 is switched from
elastically abutting on the first support surface 322 to
elastically abutting on the second support surface 323, the
connection 324 may initially abut on the third support surface 341
and receive the reaction force of elastic member 35, or at least
receive the reaction force of elastic member 35 earlier than that
the third support surface 341 is switched from elastically abutting
on the second support surface 323 to elastically abutting on the
first support surface 322. Therefore, in this case, the hinge 30
may need a smaller force to switch from elastically abutting on the
first support surface 322 to elastically abutting on the second
support surface 323. Therefore, the force required to move the
speaker 21 may be small when the user uses the speaker 21, which is
convenient for the user.
[0125] Further, the third support surface 341 may include a first
sub-support surface 3413 and a second sub-support surface 3414. In
some embodiments, the first position 3411 may be disposed on the
first sub-support surface 3413. The second position 3412 may be
disposed on the second sub-support surface 3414. That is, the first
sub-support surface 3413 and the second sub-support surface 3414
may be disposed near the two ends of the third support surface 341,
respectively.
[0126] In some embodiments, the second sub-support surface 3414 may
be a plane. Specifically, when the first support surface 322 or the
second support surface 323 elastically abuts on the third support
surface 341, the second sub-support surface 3414 may be parallel to
the first support surface 322 or the second support surface 323.
The first sub-support surface 3413 may be a flat surface or a
curved surface, and be not limited herein.
[0127] Further, the first sub-support surface 3413 and the second
sub-support surface 3414 may not be located in the same plane. The
first sub-support surface 3413 may be inclined relative to the
second sub-support surface 3414. An included angle between the two
sub-support surfaces may be no greater than 10 degree, for example,
no greater than 2 degrees, 4 degrees, 6 degrees, 8 degrees, 10
degrees, etc. Specifically, the first sub-support surface 3413 may
be disposed in a direction away from the hinge arm 32. Therefore,
in the section perpendicular to the central axis of the rotating
shaft 33, the distance between the first position 3411 and the
elastic member 35 and the distance between the first position 3411
and the contact point of the elastic member 35 in the direction of
the elastic offset of the elastic member 35 may be less than the
distance between the second position 3412 and the contact point in
the direction of the elastic offset. In some embodiments, when the
first sub-support surface 3413 is a curved surface and the second
sub-support surface 3414 is a flat surface, the included angle
between the first sub support surface 3413 and the second
sub-support surface 3414 may be an included angle between a plane
tangent to the first sub support surface 3413 and the second sub
support surface 3414 at the intersection of the two sub-support
surfaces.
[0128] Referring to FIG. 15, FIG. 15 is an exploded structural
diagram illustrating a hinge according to an embodiment of the
present disclosure. In the embodiment, the hinge mount 31 may
include a mount body 313, and a first lug 314 and a second lug 315
protruding from the mount body 313 and spaced from each other. The
hinge arm 32 may include an arm body 325 and a third lug 326
protruding from the arm body 325. The third lug 326 may be inserted
into an interval region between the first lug 314 and the second
lug 315, and rotatably connected to the first lug 314 and the
second lug 315 via the rotating shaft 33. The first support surface
322 and the second support surface 323 may be disposed on the third
lug 326. The support member 34 may be at least partially disposed
in the interval region and located at the side of the third lug 326
towards the mount body 313. The mount body 313 may be disposed with
an accommodation chamber 3121 communicating with the interval
region. The elastic member 35 may be disposed inside the
accommodation chamber 3121, and allow the support member 34
elastically offset towards the third lug 326.
[0129] Specifically, corresponding positions of the first lug 314,
the second lug 315, and the third lug 326 may be respectively
disposed with a first through-hole, a second through-hole, and a
third through-hole located in a same axial direction. Inner
diameters of the three through-holes may be no less than the outer
diameter of the rotating shaft 33. Thus, when the rotating shaft 33
passes through a corresponding through-hole, the hinge mount 31
where the first lug 314 and the second lug 315 are located may be
rotatably connected to the hinge arm 32 where the third lug 326 is
located.
[0130] In some embodiments, the first support surface 322 and the
second support surface 323 may be both disposed on the third lug
326 and parallel to the central axis of the rotating shaft 33.
Therefore, the first support surface 322 and the second support
surface 323 may enter the interval region between the first lug 314
and the second lug 315 when the hinge arm 32 rotates around the
rotating shaft 33 relative to the hinge mount 31.
[0131] Further, the support member 34 may be located between the
first lug 314 and the second lug 315 of the mount body 313. The
third support surface 341 of the support member 34 may be disposed
toward the third lug 326. In one application scenario, the elastic
member 35 may be completely set inside the accommodation chamber
3121, and touch the support member 34 at the side towards the
interval region between the first lug 314 and the second lug 315.
When the elastic member 35 is in a natural state, a region of the
support member 34 near the elastic member 35 may be at least
partially located inside the accommodation chamber 3121. It should
be noted that the shape of the portion of the support member 34
inside the accommodation chamber 3121 may match the shape of the
accommodation chamber 3121. Therefore, the portion of the support
member 34 located inside the accommodation chamber 3121 may stably
slide inside the accommodation chamber 3121 when the support member
34 is elastically offset via the elastic member 35.
[0132] In an application scenario, a sectional area of the
accommodation chamber 3121 may be less than a sectional area of the
interval region between the first lug 314 and the second lug 315 in
a section perpendicular to the length direction of the hinge mount
31. The shape of the support member 34 region outside the
accommodation chamber 3121 may match the interval region.
Therefore, the support member 34 may not all enter the
accommodation chamber 3121 upon moving toward a side of the elastic
member 35.
[0133] Of course, in other embodiments, the sectional shape of the
accommodation chamber 3121 may be the same as the interval region
between the first lug 314 and the second lug 315 in the section
perpendicular to the length direction of the hinge mount 31. At
this time, the support member 34 may completely enter the
accommodation chamber 3121. Therefore, the support member 34 may
slide inside the entire accommodation chamber 3121 upon receiving a
pushing force.
[0134] Further, when the hinge 30 in the embodiment is applied to
the hinge component 122 in the embodiment of the hinge component in
present disclosure, the first end surface 312 of the hinge mount 31
may be an end surface of the first lug 314 and the second lug 315
toward the hinge arm 32. The third lug 326 facing a protrusion
toward the arm body 325 may be located inside the interval region
between the first lug 314 and the second lug 315. Therefore, the
first end surface 312 of the first lug 314 and the second lug 315
may be disposed toward the arm body 325. In a section of the
central axis direction of the rotating shaft 33, the arm body 325
may be further protruded from the third lug 326 to form a second
end surface 321 of the first lug 314 and the second lug 315 toward
the hinge mount 31.
[0135] In the embodiment, during the relative rotation of the hinge
arm 32 and the hinge mount 31, a gap between the first end surface
312 of the first lug 314 and the second lug 315 and the second end
surface 321 of the arm body 325 may always be larger or smaller
than the diameter of the connection wire 60, Therefore, the
connection wire 60 may not be sandwiched between the first lug 314
and the second lug 315 and the arm body 325 during the relative
rotation of the hinge mount 31 and the hinge arm 32, thereby
reducing the damage of the connection wire 60 by the hinge 30.
[0136] In an application scenario, the gap between the second end
surface 321 of the first lug 314 and the second lug 315 and the
first end surface 312 of the arm body 325 may always be kept much
larger or smaller than the diameter of the connection wire 60
during the relative rotation of the hinge arm 32 and the hinge
mount 31, thereby further reducing the damage of the connection
wire 60 by the hinge 30.
[0137] It should be noted that, in the embodiment, the gap between
the first end surface 312 and the second end surface 321 may be a
gap with even size, thereby satisfying the above condition of being
greater than or less than the diameter of the connection wire 60.
Alternatively, in another embodiment, only gaps of positions at
both end surfaces dose to the connection wire 60 may be greater
than or less than the diameter of the connection wire 60. Gaps of
other positions at both end surfaces may not need to satisfy the
condition.
[0138] Specifically, in an application scenario, in a section
perpendicular to the central axis of the rotating shaft 33, at
least one of an end surface of the first lug 314 and the second lug
315 towards the hinge arm 32 and an end surface of the arm body 325
towards the hinge mount 31 may be in a chamfer setting. Therefore,
during the relative rotation of the hinge arm 32 and the hinge
mount 31, the positions close to the connection wire 60 may always
be kept larger than the diameter of the connection wire 60.
[0139] In some embodiments, the chamfer setting may be filleted, or
directly chamfered.
[0140] In the application scenario, it may be only necessary to
chamfer at least one of the end surface of the first lug 314 and
the second lug 315 near the connection wire 60 towards the hinge
arm 32 and the end surface of the arm body 325 towards the hinge
mount 31. Therefore, during the relative rotation of the hinge arm
32 and the hinge mount 31, the connection wire 60 may not be
clamped into the gap between the two end surfaces.
[0141] The hinge in the embodiment of the present disclosure may be
applied to the embodiment of the hinge component in the present
disclosure, and not be limited herein. In other embodiments, it may
also be applied to other hinge components, or a direct connection
of two components that need to be rotatably connected.
[0142] It should be noted that the above description of the hinge
component of the glasses is only a specific example, and should not
be regarded as the only feasible implementation solution.
Obviously, for those skilled in the art, after understanding the
basic principle of the hinge component of glasses, it may be
possible to make various modifications and changes in the form and
details of the specific method and operation of implementing the
hinge component of the glasses without departing from these
principles, but these modifications and changes are still within
the scope described above. For example, the sectional shape of the
hinge mount 31 and the hinge chamber 41 may be circular, oval,
trapezoidal, or the like. AH such variations may be within the
protection scope of the present disclosure.
[0143] In some embodiments, the glasses may also include a key
module. In some embodiments, the key module may include a power
switch key, a function shortcut key, and a menu shortcut key. In
some embodiments, the functional shortcut key may include a volume
plus key and a volume minus key for adjusting a sound volume, a
fast forward key and a fast back key for adjusting a progress of a
sound file, and a key for controlling a connection (e.g., Bluetooth
connection) between the glasses and an external device. In some
embodiments, the key module may include both physical and virtual
keys. For example, when the key module is in a form of a physical
key, the key may be disposed on a glasses leg 12, the glasses frame
11, or the main body 121. When a user wears the glasses in the
embodiment, the key module may not be in contact with human skin
and exposed outside, so as to facilitate the user to wear the
glasses and operate the key. In some embodiments, an end surface of
each key in the key module may be provided with a mark
corresponding to a function of the key. The mark may specifically
include texts (e.g., Chinese and English), symbols (e.g., the
volume plus key is marked with "+", the volume minus key is marked
with "-"). In some embodiments, the mark may be placed on the key
by means of laser printing, screen printing, pad printing, laser
packing, thermal sublimation, hollow-out writing, etc. In some
embodiments, the mark on the key may also be disposed on a surface
of the housing surrounding the key, which may also play a role of
identification. In some embodiments, a touch screen may be selected
for the glasses. A control program installed in the glasses may
generate the virtual key on the touch screen with an interactive
function. The virtual key may be used to select functions, volume,
and files of the glasses. In addition, the glasses may also be a
combination of a physical display and a physical key.
[0144] In some embodiments, the function member of the glasses may
be a speaker 21. At least one key module 4d may be disposed on the
speaker 21. In some embodiments, the key module 4d may be used for
human-computer interaction. For example, the key module 4d may be
used for implementing a pause/start function, a recording function,
a call answering function, etc. It should be noted that the key
module 4d is only for illustrative purposes, those skilled in the
art may adjust parameters such as a position, a count, a shape,
etc. of the key module on the basis of fully understanding the
function of the key module.
[0145] In some embodiments, the key module 4d may implement
different interaction functions based on operation instructions of
the user. For example, clicking the key module 4d once may
implement the pause/start (e.g., music, recording, etc.) function.
As another example, quickly double-clicking the key module 4d may
implement the call answering function. As a further example,
regularly choking (e.g., for a total of twice clicks, clicking
every other second) the key module 4d may implement the recording
function. In some embodiments, the operation instructions of the
user may include clicking, sliding, scrolling, or the like, or any
combination thereof. For example, sliding up and down on a surface
of the key module 4d may implement the function of turning the
volume up/down.
[0146] In some other embodiments, there may be at least two key
modules 4d, which respectively correspond to the left and right ear
hooks. The user may use the left and right hands to operate the two
key modules 4d respectively to improve user experience.
[0147] In some embodiments, in order to further improve the
human-computer interaction experience of the user, the functions of
the human-computer interaction may be assigned to the two key
modules 4d on the left and right, and the user may operate the key
modules 4d according to different functions of the key modules 4d.
For example, for the key module 4d on the left, clicking once may
turn on the recording function; clicking again may turn off the
recording function; quickly clicking twice may implement the
pause/play function. As another example, for the key module 4d on
the right, quickly clicking twice may implement the call answering
function (if music is playing at this time and there is no phone
call, quickly clicking twice may implement the function of
switching to the next/previous song).
[0148] In some embodiments, the functions corresponding to the left
and right key modules 4d may be user-defined. For example, the user
may assign, via an application software, the pause/play function
performed by the left key module 4d to the right key module 4d. As
another example, the call answering function performed by the right
key module 4d may be assigned to the left key module 4d. Further,
for operating instructions (e.g., clicking times, sliding gestures)
to implement corresponding functions may be set by the user through
the application software. For example, the operation instruction
corresponding to the call answering function may be set from
clicking once to clicking twice, and the operation instruction
corresponding to the function of switching to the next/previous
song may be set from clicking twice to clicking three times.
User-definition may be in accordance with operation habits of the
user, to a certain extent, to avoid operation errors and improve
the user experience.
[0149] In some embodiments, the functions of the human-computer
interaction may not be unique, but may be set according to
functions commonly used by the user. For example, the key module 4d
may also implement functions such as rejecting calls and reading
voice messages, and the user may customize the functions and
operation instructions corresponding to the functions to meet
different needs.
[0150] In some embodiments, the glasses may be connected to an
external device through at least one key module. For example, the
glasses may be connected to a mobile phone through a key on the
glasses that controls a wireless connection (e.g., a key that
controls a Bluetooth connection). Optionally, when a connection is
established, the user may operate the glasses directly on the
external device (e.g., a mobile phone) to perform one or more of
the functions mentioned above.
[0151] It should be noted that the above description of the glasses
may be only specific examples, and should be not considered as the
only feasible implementation. Obviously, for those skilled in the
art, after understanding the basic principle of the glasses, it may
be possible to make various modifications and changes in the form
and details of the specific manner and operation of implementing
the glasses without departing from these principles, these
modifications and changes are still within the scope described
above. For example, the shape of the key may have a regular shape
such as a rectangle, a circle, an ellipse and a triangle, or may
have an irregular shape. As another example, the shape of each key
may be the same or different. All such variations may be within the
protection scope of the present disclosure.
[0152] In some embodiments, the glasses may further include a voice
control function. FIG. 16 is a block diagram illustrating voice
control modules of glasses according to some embodiments of the
present disclosure. The voice control system may be a portion of
the auxiliary key module, or may be served as a separate model
integrated in the speaker. In some embodiments, the voice control
system may include a receiving module 601, a processing module 603,
an identification module 605, and a control module 607.
[0153] The receiving module 601 may be configured to receive a
voice control instruction and send the voice control instruction to
the processing module 603. In some embodiments, the receiving
module 601 may include one or more microphones. In some
embodiments, when the receiving module 601 receives the voice
control instruction inputted by a user, (e.g., the receiving module
601 receives a voice control instruction of "start playing"), the
receiving module 601 may then send the voice control instruction to
the processing module 606.
[0154] The processing module 603 may be in communication with the
receiving module 601, generate an instruction signal according to
the voice control instruction, and send the instruction signal to
the identification module 605.
[0155] In some embodiments, when the processing module 603 receives
the voice control instruction inputted by the user from the
receiving module 601 through the communication connection, the
processing module 603 may generate an instruction signal according
to the voice control instruction.
[0156] In some embodiments, the identification module 605 may be in
communication with the processing module 603 and the control module
607, identify whether the instruction signal matches a preset
signal, and send a matching result to the control module 607.
[0157] In some embodiments, when the identification module 605
determines that the instruction signal matches the preset signal,
the identification module 605 may send the matching result to the
control module 607. The control module 607 may control the
operation of the speaker according to the instruction signal. For
example, when the receiving module 601 receives a voice control
instruction of "start playing", and when the identification module
605 determines that the instruction signal corresponding to the
voice control instruction matches the preset signal, the control
module 607 may automatically perform the voice control instruction,
that is, immediately start playing audio data. When the instruction
signal does not match the preset signal, the control module 607 may
not perform the control instruction.
[0158] In some embodiments, the voice control system may further
include a storage module, which is in communication with the
receiving module 601, the processing module 603, and the
identification module 605. The receiving module 601 may receive and
send a preset voice control instruction to the processing module
603. The processing module 603 may generate a preset signal
according to the preset voice control instruction, and send the
preset signal to the storage module.
[0159] When the identification module 605 needs to match the
instruction signal received from the processing module 603 by the
receiving module 601 with the preset signal, the storage module may
send the preset signal to the identification module 605 through the
communication connection.
[0160] In some embodiments, the processing module 603 may further
include removing environmental sound contained in the voice control
instruction.
[0161] In some embodiments, the processing module 603 in the voice
control system may further include performing denoising processing
on the voice control instruction. The denoising processing may
refer to removing the environmental sound contained in the voice
control instruction. In some embodiments, for example, when in a
complex environment, the receiving module 601 may receive and send
the voice control instruction to the processing module 603. Before
the processing module 603 generates the corresponding instruction
signal according to the voice control instruction, in order to
prevent the environmental sound from interfering with the
recognition process of the identification module 605, the voice
control instruction may first be denoised. For example, when the
receiving module 601 receives a voice control instruction inputted
by the user when the user is in an outdoor environment, the voice
control instruction may include environmental sound such as vehicle
driving on the road, whistle, and the processing module 602 may
perform the denoising processing to reduce the influence of the
environmental sound on the voice control instruction.
[0162] It should be noted that the above description of the voice
control system is only a specific example and should not be
considered as the only feasible implementation solution. Obviously,
for persons having ordinary skills in the art, after understanding
the basic principle of the voice control system, various
modifications and changes may be made in the form and details of
the specific ways and steps of implementing the voice control
system without departing from the principle, but these
modifications and changes are still within the scope of the present
disclosure. For example, the receiving module 601 and the
processing module 603 may be combined into one single module. All
such variations are within the protection scope of the present
disclosure.
[0163] In some embodiments, the speaker may also include an
indicator lamp module (not shown in the figure) to display the
working status of the speaker. Specifically, the indicator lamp
module (also referred to as indicator lamp) may emit a light
signal, and the working status of the speaker may be known by
observing the light signal.
[0164] In some embodiments, the indicator lamp may show the power
of the speaker. For example, when the indicating lamp is red, it
means that the power of the speaker is insufficient (for example,
the power is less than 5%, 10%, etc.), As another example, when the
speaker is charging, the indicator lamp may blink. As a further
example, when the indicating lamp is green, it means that the
speaker may have sufficient power (for example, the power is above
50%, 80%, etc.). In some embodiments, the color of the indicator
lamp may be adjusted as needed, which is not limited herein.
[0165] Of course, it can be understood that the indicator lamp may
indicate the power of the speaker in other ways. In some
embodiments, there may be multiple indicator lamps, and the current
power of the speaker may be represented by the number of indicator
lamps that are luminous. Specifically, in an application scenario,
there may be three indicator lamps. When only one indicator lamp is
luminous, it may indicate that the power of the speaker is
insufficient, and the power may be turned off at any time (e.g.,
the power is between 1% to 20%). When only two indicator lamps are
luminous, it may indicate that the power of the speaker may be in a
normal use state and can be charged (e.g., the power is between 21%
to 70%, etc.). When the three indicator lamps are luminous, it may
indicate that the power of the speaker may be in a full state, no
charging is required, and the standby time is long (e.g., the power
is at 71%.about.100%, etc.).
[0166] In some embodiments, the indicator lamp may indicate the
current communication status of the speaker. For example, when the
speaker is in communication with other devices (e.g., via Wi-Fi
connection, Bluetooth connection, etc.), the indicator lamp may
remain blinking, or may be displayed as other colors (e.g.,
blue).
[0167] It should be noted that the above description of the speaker
is only a specific example, and should not be regarded as the only
feasible implementation solution. Obviously, for persons having
ordinary skills in the art, after understanding the basic principle
of the speaker, various modifications and changes may be made in
form and detail of the specific ways and steps of implementing the
speaker without departing from the principle, but these
modifications and changes are still within the scope of the present
disclosure. For example, when the speaker is in a charging state,
the indicator lamp may be displayed as another color (e.g.,
purple). All such variations are within the protection scope of the
present disclosure.
[0168] In typical cases, the sound quality of the speaker may be
affected by various factors such as the physical properties of
components of the speaker, vibration transmission relationship(s)
between the components, a vibration transmission relationship
between the speaker and the outside, and the efficiency of a
vibration transmission system when vibration is transmitted. The
components of the speaker may include a component that generates
the vibration (e.g., but is not limited to a transducing device), a
component that fixes the speaker (e.g., but is not limited to an
ear hook), and a component that transmits the vibration (e.g., but
is not limited to a panel, a vibration transmission layer, etc.).
The vibration transmission relationship(s) between the components
and the vibration transmission relationship between the speaker and
the outside may be determined by a contact mode (e.g., but is not
limited to, a clamping force, a contact area, a contact shape,
etc.) between the speaker and the user.
[0169] For the purpose of illustration only, relationship(s)
between the sound quality and the components of the speaker may be
further described below based on the speaker. It may need to be
known that the contents described below may also be applied to an
air conduction speaker without violating the principle.
[0170] FIG. 17 is an equivalent model illustrating a vibration
generation and transmission system of a speaker according to some
embodiments of the present disclosure. As shown in FIG. 17, it may
include a fixed end 1101, a sensing terminal 1102, a vibration unit
1103, and a transducing device 1104. As used herein, the fixed end
1101 may be connected to the vibration unit 1103 based on a
transmission relationship K1 (k.sub.4 in FIG. 17). The sensing
terminal 1102 may be connected to the vibration unit 1103 based on
a transmission relationship K2 (R.sub.3, k.sub.3 in FIG. 17). The
vibration unit 1103 may be connected to the transducing device 1104
based on a transmission relationship K3 (R.sub.4, k.sub.5 in FIG.
17).
[0171] The vibration unit mentioned herein may be a vibrating body
including a panel and a transducing device. The transmission
relationships K1, K2, and K3 may be descriptions of functional
relationships between corresponding portions of an equivalent
system of the speaker (described in detail below). The vibration
equation of the equivalent system may be expressed as:
m.sub.3x.sub.3''+R.sub.3x.sub.3'-R.sub.4x.sub.4'+(k.sub.3+k.sub.4)x.sub.-
3+k.sub.5(x.sub.3-x.sub.4)=f.sub.3 (1)
m.sub.4x.sub.4''+R.sub.4x.sub.4''-k.sub.5(x.sub.3-x.sub.4)=f.sub.4
(2)
[0172] As used herein, m.sub.3 is an equivalent mass of the
vibration unit 1103, m.sub.4 is an equivalent mass of the
transducing device 1104, x.sub.3 is an equivalent displacement of
the vibration unit 1103, x.sub.4 is an equivalent displacement of
the transducing device 1104, k.sub.3 is an equivalent elastic
coefficient between the sensing terminal 1102 and the vibration
unit 1103, x.sub.4 is an equivalent elastic coefficient between the
fixed end 1101 and the vibration unit 1103, k.sub.5 is an
equivalent elastic coefficient between the transducing device 1104
and the vibration unit 1103, R.sub.3 is an equivalent damping
between sensing terminal 1102 and vibration unit 1103, R.sub.4 is
an equivalent damping between the transducing device 1104 and the
vibration unit 1103, and f.sub.3 and f.sub.4 are interaction forces
between the vibration unit 1103 and the transducing device 1104,
respectively. An equivalent amplitude A.sub.3 of the vibration unit
in the system may be:
A 3 = - m 4 .times. .omega. 2 ( m 3 .times. .omega. 2 + j .times.
.times. .omega. .times. .times. R 3 - ( k 3 + k 4 + k 5 ) ) ( m 4
.times. .omega. 2 + j .times. .times. .omega. .times. .times. R 4 -
k 5 ) - k 5 .function. ( k 5 - j .times. .times. .omega. .times.
.times. R 4 ) f 0 ( 3 ) ##EQU00001##
As used herein, f.sub.0 denotes a driving force unit, and co
denotes a vibration frequency. It may be seen that factors
affecting a frequency response of a bone conduction speaker may
include a vibration generation portion (e.g., but is not limited to
a vibration unit, a transducing device, a housing, and
interconnection manners, such as m.sub.3, m.sub.4, k.sub.5,
R.sub.4, etc., in equation (3)), a vibration transmission portion
(e.g., but is not limited to, a contact manner with the skin, and
properties of the glasses rim, such as k.sub.3, k.sub.4, R.sub.3,
etc., in the equation (3)). The change of structures of the
components of the speaker and parameters of connections between the
components may change the frequency response and sound quality of
the bone conduction speaker. For example, the change of a clamping
force may be equivalent to changing the size of k.sub.4. The change
of a bonding manner of glue may be equivalent to changing the size
of R.sub.4 and k.sub.r. The change of the hardness, elasticity,
damping, etc., of a relevant material may be equivalent to changing
the size of k.sub.3 and R.sub.3.
[0173] In a specific embodiment, the fixed end 1101 may be points
or regions relatively fixed in the bone conduction speaker during
the vibration (e.g., the ear hook). These points or regions may be
regarded as the fixed end of the bone conduction speaker during the
vibration. The fixed end may constitute a specific component, or a
position determined according to the overall structure of the bone
conduction speaker. For example, the bone conduction speaker may be
hung, bonded, or adsorbed near human ears by a specific device. The
structure and shape of the bone conduction speaker may be designed
so that a bone conduction part may be attached to the human
skin.
[0174] The sensing terminal 1102 may be a hearing system for the
human body to receive sound signal(s). The vibration unit 1103 may
be portions of the bone conduction speaker for protecting,
supporting, and connecting the transducing device, including
portions that directly or indirectly contact the user, such as a
vibration transmission layer or panel that transmits the vibration
to the user, a housing that protects and supports other
vibration-generating units, etc. The transducing device 1104 may be
a sound vibration generating device, which may be one or more the
transducing devices discussed above or any combination thereof.
[0175] The transmission relationship K1 may connect the fixed end
1101 and the vibration unit 1103, and represent a vibration
transmission relationship between a vibration generating portion
and the fixed end during the work of the bone conduction speaker.
K1 may be determined according to the shape and structure of the
bone conduction device. For example, the bone conduction speaker
may be fixed to the human head in the form of a U-shaped earphone
holder/earphone strap, or installed on a helmet, fire mask or other
special-purpose masks, glasses, etc. The shapes and structures of
different bone conduction speakers may affect the vibration
transmission relationship K1. Further, the structure of the speaker
may also include physical properties such as composition materials,
qualities, etc., of different portions of the bone conduction
speaker. The transmission relationship K2 may connect the sensing
terminal 402 and the vibration unit 1103.
[0176] K2 may be determined according to the composition of the
transmission system. The transmission system may include but be not
limited to transmitting sound vibration to the hearing system
through tissues of the user. For example, when the sound is
transmitted to the hearing system through the skin, subcutaneous
tissues, bones, etc., the physical properties of different human
tissues and their interconnections may affect K2. Further, the
vibration unit 1103 may be in contact with the human tissue. In
different embodiments, a contact surface on the vibration unit may
be a side of a vibration transmission layer or panel. A surface
shape, size of the contact surface, and an interaction force with
the human tissue may affect the transmission relationship K2.
[0177] The transmission relationship K3 between the vibration unit
1103 and the transducing device 1104 may be determined by
connection properties inside the vibration generating device of the
bone conduction speaker. The transducing device and the vibration
unit may be connected in a rigid or elastic manner. Alternatively,
the change of a relative position of a connecting piece between the
transducing device and the vibration unit may change the
transmission device to transmit the vibration to the vibrating unit
(in particular, the transmission efficiency of the panel), thereby
affecting the transmission relationship K3.
[0178] During the use of the bone conduction speaker, the sound
generation and transmission process may affect the final sound
quality felt by the human body. For example, the above-mentioned
fixed end, the human sensing terminal, the vibration unit, the
transducing device, and the transmission relationships K1, K2, and
K3, etc., may all affect the sound quality of the bone conduction
speaker. It should be noted that K1, K2, and K3 are only a
representation of the connection modes of different device portions
or systems involved in the vibration transmission process, and may
include, but be not limited to, a physical connection manner, a
force transmission manner, the sound transmission efficiency, or
the like.
[0179] The above description of the equivalent system of speaker is
only a specific example and should not be regarded as the only
feasible implementation solution. Obviously, for persons having
ordinary skills in the art, after understanding the basic principle
of the speaker, various modifications and changes may be made in
the form and details of the specific ways and steps that affect the
vibration transmission of the speaker without departing from the
principle, but these modifications and changes are still within the
scope of the present disclosure. For example, K1, K2, and K3
described above may be a simple vibration or mechanical
transmission way, or may include a complex non-linear transmission
system. The transmission relationship may include transmission
through direct connection of various components (or parts), or may
include transmission through a non-contact way.
[0180] FIG. 18 is a structural diagram illustrating a composite
vibration device of a speaker according to some embodiments of the
present disclosure.
[0181] In some embodiments, the composite vibration device may be
disposed on glasses. In some embodiments, the composite vibration
device may be a portion of the transducing device. In some
embodiments, the composite vibration device in FIG. 18 may be a
vibration portion that provides a sound inside an earphone core.
Specifically, the composite vibration device in some embodiments of
the present disclosure may be equivalent to a specific
representation of the transmission relationship K3 of the vibration
unit 1103 and the transducing device 1104 in FIG. 17. Embodiments
of the composite vibration device of the speaker may be shown in
FIG. 18 and FIG. 19. A vibration transmission plate 1801 and a
vibration plate 1802 may form the composite vibration device. The
vibration transmission plate 1801 may be disposed as a first
annular body 1813. The first annular body may be disposed with
three first supporting rods 1814 converged towards a center. A
center position of the converged center may be fixed at the center
of the vibration plate 1802. The center of the vibration plate 1802
may be a groove 1820 matching the converged center and the first
support rods. The vibration plate 1802 may be disposed with a
second annular body 1821 having a radius different from that of the
vibration transmission plate 1801, and three second supporting rods
1822 having different thicknesses from that of the first supporting
rod 1814. During assembly, the first supporting rods 1814 and the
second supporting rods 1822 may be staggered and shown an angle
being but be not limited to 60 degrees.
[0182] The first and second supporting rods may both be straight
rods or other shapes that meet specific requirements. The count of
supporting rods may be more than two, and symmetrical or
asymmetrical arrangement may be adapted to meet requirements of
economy and practical effects. The vibration transmission plate
1801 may have a thin thickness and be able to increase an elastic
force. The vibration transmission plate 1801 may be clamped in the
center of the groove 1820 of the vibration plate 1802. A voice coil
1808 may be attached to a lower side of the second annular body
1821 of the vibration plate 1802. The composite vibration device
may further include a bottom plate 1812. The bottom plate 1812 may
be disposed with an annular magnet 1810. An inner magnet 1811 may
be concentrically disposed in the annular magnet 1810. An inner
magnetic conduction plate 1809 may be disposed on the top surface
of the inner magnet 1811. An annular magnetic conduction plate 1807
may be disposed on the annular magnet 1810. A washer 1806 may be
fixedly disposed above the annular magnetic conduction plate 1801.
The first annular body 1813 of the vibration transmission plate
1801 may be fixedly connected to the washer 1806. The entire
composite vibration device may be connected to the outside through
a panel 1830. The panel 1830 may be fixedly connected to the
converged center of the vibration transmission plate 1801, and
fixed to the center of the vibration transmission plate 1801 and
the vibration plate 1802. Using the composite vibration device
constituting the vibrating plate and the vibration transmission
plate, a frequency response shown in FIG. 20 may be obtained and
two resonance peaks may be generated. By adjusting parameters such
as the size and material of the two components (e.g., the vibration
conductive plate and the vibration board) may make the resonance
peaks appear in different positions. For example, a low-frequency
resonance peak appears at a position at a lower frequency, and/or a
high-frequency resonance peak appears at a position at a higher
frequency. Preferably, the stiffness coefficient of the vibration
board may be greater than the stiffness coefficient of the
vibration conductive plate. The vibration board may generate the
high-frequency resonance peak of the two resonance peaks, and the
vibration conductive plate may generate the low-frequency resonance
peak of the two resonance peaks. The resonance peaks may be or may
not be within the frequency range of sound perceivable by human
ears. Preferably, neither of the resonance peaks may be within the
frequency range of sound perceivable by the human ears. More
preferably, one resonance peak may be within the frequency range of
sound perceivable by the human ears, and another resonance peak may
not be within the frequency range of sound perceivable by the human
ears. Further preferably, both resonance peaks may be within the
frequency range of sound perceivable by the human ears. Still
further preferably, both resonance peaks may be within the
frequency range of sound perceivable by the human ears, and their
frequencies may be between 80 Hz-18000 Hz, Still further
preferably, both resonance peaks may be within the frequency range
of sound perceivable by the human ears, and their frequencies may
be between 200 Hz-15000 Hz. Still further preferably, both
resonance peaks may be within the frequency range of sound
perceivable by the human ears, and their frequencies may be between
500 Hz-12000 Hz, Still further preferably, both resonance peaks may
be within the frequency range of sound perceivable by the human
ears, and their frequencies may be between 800 Hz-11000 Hz. The
frequencies of the resonance peaks may have a certain gap. For
example, the frequency difference between the two resonance peaks
may be at least 500 Hz. Preferably, the frequency difference
between the two resonance peaks may be at least 1000 Hz. More
preferably, the frequency difference between the two resonance

(about 600 Hz) and improves the sound quality.
[0185] By changing parameters such as the size and material of the
first vibration transmission plate, the resonance peak(s) may be
shifted to obtain an ideal frequency response. Preferably, the
first vibration transmission plate may be an elastic plate. The
elasticity may be determined by various aspects such as the
material, thickness, and structure of the first vibration
transmission plate. The material of the first vibration
transmission plate may be, but be not limited to, steel (such as,
but is not limited to, stainless steel, carbon steel, etc.), a
light alloy (such as, but is not limited to, an aluminum alloy, a
beryllium copper, a magnesium alloy, a titanium alloy, etc.),
plastics (such as, but being is limited to, high-molecular
polyethylene, blown nylon, engineering plastics, etc.), other
single or composite materials capable of implementing the same
performance. The composite materials may be but be not limited to a
reinforcing material, for example, glass fiber, carbon fiber, boron
fiber, graphite fiber, graphene fiber, silicon carbide fiber,
aramid fiber, etc. The composite materials may also be a composite
of other organic and/or inorganic materials, such as various types
of glass steels constituted by glass fiber reinforcing unsaturated
polyester, epoxy resin, or phenolic resin. The thickness of the
first vibration transmission plate may not be less than 0.005 mm.
Preferably, the thickness may be 0.005 mm to 3 mm. More preferably,

transmission plate may be disposed in a ring shape, and preferably
include at least one ring. Preferably, the structure may include at
least two rings, which may be concentric rings or non-concentric
rings. The rings may be connected by at least two supporting rods
that centrally radiate from the outer ring to the inner ring.
Further preferably, the structure may include at least one
elliptical ring. Further preferably, the structure may include at
least two elliptical rings. Different elliptical rings may have a
different radius of curvature. The rings may be connected by the
supporting rods. Still further preferably, the first vibration
transmission plate may include at least one square ring. The
structure of the first vibration transmission plate may also be
disposed in a plate shape. Preferably, a hollow pattern may be
disposed on the first vibration transmission plate, and the area of
the hollow pattern may not be less than the area without a hollow
pattern. The material, thickness, and structure described above may
be combined to form different vibration transmission plates. For
example, the ring-shaped vibration transmission plate may have
different thickness distributions. Preferably, the thickness of the
supporting rod may be equal to the thickness of the ring. Further
preferably, the thickness of the supporting rod may be greater than
the thickness of the ring. More preferably, the thickness of the
inner ring may be greater than the thickness of the outer ring.
[0186] The content disclosed in the present disclosure may also
disclose specific embodiments of the vibration plate, the first
vibration transmitting piece, and the second vibration transmitting
piece described above. FIG. 23 is a structural diagram illustrating
a vibration generating portion of a MP3 player according to some
embodiments of the present disclosure. As shown in FIG. 23, a
transducing device may include a magnetic circuit system
constituted by a magnetic conduction plate 2210, a magnetic system
constituted by a magnet 2211 and a magnetizer 2212, a vibration
plate 2214, a coil 2215, a first vibration transmission plate 2216,
and a second vibration transmission plate 2217. A panel 2213 (i.e.,
a side of the core housing close to a user) may protrude from a
core housing 2219, and be bonded to the vibration plate 2214 by
glue. The first vibration transmission plate 2216 may connect and
fix the transducing device on the core housing 2219 to form a
suspension structure.
[0187] During the working of the speaker, a triple vibration system
constituted by the vibration plate 2214, the first vibration
transmission plate 2216, and the second vibration transmission
plate 2217 may generate a flatter frequency response curve, thereby
improving the sound quality of the speaker. The first vibration
transmission plate 2216 may elastically connect the transducing
device to the core housing 2219, which may reduce the vibration
transmitted by the transducing device to the housing, thereby
effectively reducing a leaked sound caused by the vibration of the
housing, and also reducing the influence of the vibration of the
housing on the sound quality of the speaker. FIG. 24 is a schematic
diagram illustrating a vibration response curves of a housing
vibration strength and a plate vibration strength according to some
embodiments of the present disclosure. As used herein, the thick
line may show the frequency response of the vibration generating
portion when the first vibration transmission plate 2216 is used,
and the thin line may show the frequency response of the vibration
generating portion when the first vibration transmission plate 2216
is not used. It may be seen that the vibration of the housing of
the speaker without the first vibration transmission plate 2216 may
be significantly greater than the vibration of the housing of the
speaker with the first vibration transmission plate 2216 in a
frequency range above 500 Hz. FIG. 25 is a comparison of a leaked
sound in a case of including the first vibration transmission plate
2216 and a case of excluding the first vibration transmission plate
2216. As used herein, the leaked sound of the device with the first
vibration transmission plate 2216 in an intermediate frequency
(e.g., about 1000 Hz) may be less than the leaked sound of the
device without the first vibration transmission plate 2216 in the
corresponding frequency range. It may be seen that the vibration of
the housing may be effectively reduced after using the first
vibration transmission plate between the panel and the housing,
thereby reducing the leaked sound. In some embodiments, the first
vibration transmission plate may include, but be not limited to,
stainless steel, beryllium copper, plastics, a polycarbonate
material, or the like. The thickness may be in a range of 0.01 mm-1
mm.
[0188] It should be noted that the above description of the
composite vibration component is only a specific example and should
not be considered as the only feasible implementation solution.
Obviously, for persons having ordinary skills in the art, after
understanding the basic principle of the composite vibration
component, various modifications and changes may be made in the
form and details of the specific ways and steps of implementing the
composite vibration component without departing from the principle,
but these modifications and changes are still within the scope of
the present disclosure. For example, the first vibration conductive
plate may not be limited to the one or two rings, and the number of
the rings may be more than two. As another example, the shapes of a
plurality of elements of the first vibration conductive plate may
be the same or different (e.g., a circular ring and/or a square
ring). All such variations are within the protection scope of the
present disclosure.
[0189] FIGS. 26A and 26B are schematic diagrams of a core structure
of a speaker of a glasses according to some embodiments of the
present disclosure. In the embodiment, the speaker may include a
housing 210 (i.e., the core housing), a vibration panel 221, and a
transducing device 22. In some embodiments, the transducing device
22 may be accommodated inside the housing 210 and generate a
vibration. The vibration of the transducing device 22 may cause the
housing 210 to vibrate, thereby pushing the air outside the housing
to vibrate and generate a leaked sound. At least one sound guiding
hole 230 may be disposed in at least a portion of the housing 210.
The sound guiding hole(s) 230 may be used to lead sound waves in
the housing formed by the air vibration inside the housing 210 to
the outside of the housing 210, and interfere with leaked sound
waves formed by the air outside the housing pushed by the vibration
of the housing 210. In some embodiments, the interference may
reduce the amplitude of the leaked sound waves.
[0190] The vibration panel 221 may be fixedly connected to the
transducing device 22, and synchronously vibrated by the
transducing device 22. The vibration panel 221 may protrude from
the housing 210 through an opening of the housing 210, and at least
partially fit human skins. The vibration may be transmitted to
auditory nerves through human tissues and bones, so that a person
may hear a sound. The transducing device 22 and the housing 210 may
be connected through a connection piece 23. The connection piece 23
may position the transducing device 22 inside the housing 210.
[0191] The connection piece 23 may be one or more independent
components, or disposed with the transducing device 22 or the
housing 210 as a whole. In some embodiments, in order to reduce a
constraint on the vibration, the connection piece 23 may be made of
an elastic material.
[0192] In some embodiments, the sound guiding hole(s) 230 may be
disposed in an upper portion of the height of a side wall, for
example, a portion of the side wall from the top (the panel 221) to
1/3 height along the height direction.
[0193] Taking a cylindrical housing as an example, for the
disposing position, the sound guiding hole(s) 230 may be opened in
a side wall 211 and/or a bottom wall 212 of the housing according
to different requirements. Preferably, the sound guiding hole(s)
230 may be opened in an upper portion and/or a lower portion of the
side wall 211 of the housing. The count of sound guiding holes in
the side wall 211 of the housing may be at least two, and
preferably uniformly distributed in a circularly circumferential
direction. The count of sound guiding holes in the bottom wall 212
of the housing may be at least two. With a center of the bottom
wall as the center of the ring, the holes may be uniformly
distributed in a ring shape. The sound guiding holes distributed in
the ring may be disposed as at least one ring. The count of sound
guiding holes disposed in the bottom wall 212 of the housing may be
only one. The sound guiding holes may be disposed at the center of
the bottom wall 212.
[0194] As for the count, the sound guiding hole(s) may be one or
more, preferably multiple, and evenly arranged. For ring-shaped
distributed sound guiding holes, the count of sound guiding holes
of each ring may be, for example, 6-8.
[0195] The shape of the sound guiding hole may be a ring shape, an
oval shape, a rectangular shape, or a long strip shape. The long
strip shape may generally refer to a long strip along a straight
line, a curve, an arc, or the like. Various shapes of the sound
guiding holes on the speaker may be the same or different.
[0196] In some embodiments, the penetrating sound guiding hole(s)
230 may be disposed in the lower portion of the side wall of the
housing 210 (a portion of the side wall from 2/3 height to the
bottom along the height direction). The count of the sound guiding
hole(s) 230 may be, for example, eight, and the shape may be, for
example, a rectangle, Each sound guiding hole 230 may be uniformly
distributed in a ring shape on the side wall of the housing
210.
[0197] In some embodiments, the housing 210 may be cylindrical. The
penetrating sound guiding hole(s) 230 may be disposed in a middle
portion of the side wall of the housing 210 (a portion of the side
wall from 1/3 to 2/3 height along the height direction). The count
of the sound guiding hole(s) 230 may be, for example, eight, and
the shape may be, for example, a rectangle, Each sound guiding hole
230 may be uniformly distributed in a ring shape on the side wall
of the housing 210.
[0198] In some embodiments, the penetrating sound guiding hole(s)
230 may be disposed in a circumferential direction of the bottom
wall of the housing 210. The count of the sound guiding hole(s) 230
may be, for example, eight, and the shape may be, for example, a
rectangle. Each sound guiding hole 230 may be uniformly distributed
in a ring shape on the side wall of the housing 210.
[0199] In some embodiments, the penetrating sound guiding hole(s)
230 may be respectively formed in the upper and lower portions of
the side wall of the housing 210. The sound guiding hole(s) 230 may
be uniformly distributed in the upper portion and the lower portion
of the side wall of the housing 210 in a ring shape. The count of
the sound guiding hole(s) 230 of each ring may be eight. In
addition, the sound guiding hole(s) 230 disposed at the upper and
lower portions may be symmetrically disposed relative to a middle
portion of the housing 210. The shape of each sound guiding hole
230 may be a ring.
[0200] In some embodiments, the penetrating sound guiding hole(s)
230 may be disposed in the upper portion and the lower portion of
the side wall of the housing 210, and the bottom wall of the
housing 210, respectively. The sound guiding hole(s) 230 opened on
the side wall may be evenly distributed in the upper portion and
the lower portion of the side wall of the housing 210. The count of
the hole(s) of each ring may be eight. The sound guiding hole(s)
230 disposed at the upper portion and the lower portion may be
symmetrically arranged relative to a middle portion of the housing
210. Each sound guiding hole 230 opened on the side wall may be
rectangular. The shape of the sound guiding hole(s) 230 opened on
the bottom wall may be a long strip shape arranged along an arc.
The count of the hole(s) may be four. The hole(s) may be uniformly
distributed in a ring shape with the center of the bottom wall as
the ring center. The sound guiding hole(s) 230 opened on the bottom
wall may also include a ring through-hole opened at the center.
[0201] In some embodiments, the penetrating sound guiding hole(s)
230 may be opened in the upper portion of the side wall of the
housing 210. The hole(s) may be evenly distributed in the upper
portion of the side wall of the housing 210. The count may be, for
example, eight, and the shape of the sound guiding hole(s) 230 may
be a ring.
[0202] In some embodiments, in order to show a better effect of
suppressing leaked sound, the sound guiding holes 230 may be
uniformly distributed in the upper portion, the middle portion, and
the lower portion of the side wall 11, respectively, and a ring of
the sound guiding hole(s) 230 may also be disposed in the bottom
wall 12 of the housing 210 in the circumferential direction. The
aperture of each sound guiding hole 230 and the count of the
hole(s) may be the same.
[0203] In some embodiments, the sound guiding hole 230 may be an
unobstructed through-hole.
[0204] In order to control the effect of the sound wave propagating
from the sound guiding hole(s) 230 in the housing, a damping layer
(not shown in the specification drawing) may be disposed at the
opening of the sound guiding hole(s) 230 to adjust the phase and
amplitude of the sound wave, thereby correcting and guiding the
effect of the sound wave in the housing. The material and position
of the damping layer may be set in many manners. For example, the
damping layer may be made of tuning paper, tuning cotton, non-woven
fabric, silk, cotton, sponge, rubber, or other materials with a
certain damping for sound quality conduction. The damping layer may
be attached to an inner wall of the sound guiding hole(s) 230, or
placed on the outside of the sound guiding hole(s) 230.
[0205] In some embodiments, corresponding to different sound
guiding holes, the disposed damping layer may be disposed to have
the same phase difference between the different sound guiding holes
230 to suppress the leaked sound of the same wavelength, or
different phase differences between the different sound guiding
holes 230 to suppress the leaked sound of different wavelengths
(i.e., a specific band of leaked sound).
[0206] In some embodiments, different portions of the same sound
guiding hole(s) 230 may be disposed to have the same phase (e.g.,
using a pre-designed step or step-shaped damping layer) to suppress
leaked sound waves of the same wavelength. Alternatively, different
portions of the same sound guiding hole 230 may be disposed to have
different phases to suppress leaked sound waves of different
wavelengths.
[0207] The transducing device 22 may not only drive the vibration
panel 221 to vibrate, but also be a vibration source, which is
accommodated inside the housing 210. The vibration of the surface
of the transducing device 22 may cause the air in the housing to
vibrate with the surface, Sound waves may be formed inside the
housing 210, which may be referred to as in-housing sound waves.
The vibration panel 221 and the transducing device 22 may be
located at the housing 210 through the connection piece 23. It may
be inevitable that the vibration may be applied to the housing 210
to drive the housing 210 to vibrate synchronously. Therefore, the
housing 210 may push the air outside the housing to vibrate to form
the leaked sound wave. The leaked sound wave may propagate outward,
forming the leaked sound.
[0208] According to the following equation to determine a position
of the sound guiding hole to suppress the leaked sound, the
reduction of the leaked sound may be proportional to:
(.intg..intg.s.sub.openingPds-.intg..intg.s.sub.housingP.sub.dds)

where S.sub.opening is an opening area of the sound guiding hole,
and S.sub.housing is a housing area that is not in contact with the

[0216] P.sub.a, P.sub.b, P.sub.c, P.sub.e may be all functions of
position. When a hole is opened at any position of the housing, and
the area of the hole is S, the total effect of sound pressure at
the hole may be .intg..intg.s.sub.opening Pds.
[0217] Since the vibration panel 221 on the housing 210 is closely
attached to the human tissue, and its output energy may be absorbed
by the human tissue, only the d-plane may push the air outside the
housing to vibrate to form the leaked sound. The total effect of
vibration of the air outside the housing pushed by the housing may
be .intg..intg.s.sub.housing P.sub.d ds.
[0218] In some application scenarios, our goal may be to make
.intg..intg.s.sub.opening Pds and .intg..intg.s.sub.housing
P.sub.dds equal in magnitude and opposite in direction, so as to
achieve the effect of reducing the leaked sound. Once the basic
structure of the device is determined, .intg..intg.s.sub.housing
P.sub.dds may be an amount that we can not adjust,
.intg..intg.s.sub.opening Pds may be adjusted to offset
.intg..intg.s.sub.housingP.sub.dds. .intg..intg.s.sub.opening Pds
may include complete phase and amplitude information. The phase and
amplitude may be closely related to the housing size of the
speaker, the vibration frequency of the transducing device, the
opening position, shape, count, size of the sound guiding hole(s),
and whether there is a damping on the hole, which may allow us to
implement the purpose of suppressing the leaked sound by adjusting
the opening position, shape and count of sound guiding hole(s),
and/or increasing damping and/or adjusting damping material.
[0219] The in-housing sound wave(s) and leaked sound wave(s) may be
equivalent to two sound sources shown in the figure. The
penetrating sound guiding hole(s) 230 may be opened on the wall
surface of the housing in some embodiments of the present
disclosure, which may guide the in-housing sound wave(s) to
propagate to the outside of the housing, propagate in the air with
the leaked sound waves(s), and interfere therewith, thereby
reducing the amplitude of the leaked sound wave(s), that is,
reducing the leaked sound. Therefore, the technical solution of the
present disclosure, through the convenient improvement of opening
sound guiding hole(s) in the housing, may solve the problem of the
leaked sound to a certain extent without increasing the volume and
weight of the speaker.
[0220] According to the equation derived by the inventor, those
skilled in the art may easily understand that the elimination
effect of leaked sound wave(s) may be closely related to the
housing size of the speaker, the vibration frequency of the
transducing device, the opening position, shape, count, and size of
the sound guiding hole(s), and whether there is a damping on the
hole, such that the opening position, shape, count, and the damping
material of the sound guiding hole(s) may have a variety of
different solutions according to needs.
[0221] FIG. 27 is a diagram illustrating an effect of suppressing
leaked sound of a speaker according to some embodiments of the
present disclosure. In a target region near the speaker (e.g., the
speaker shown in FIGS. 26A and 26B), a difference between a phase
of a leaked sound wave transmitted to the target region and a phase
of an in-housing sound wave propagating to the target region
through sound guiding hole(s) may be close to 180 degrees. By doing
this, the leaked sound wave generated by the housing may be
significantly reduced or even eliminated in the target region.
[0222] As shown in FIG. 27, the leaked sound wave may be
significantly suppressed in a frequency band from 1500 Hz to 4000
Hz. As used therein, within a frequency band from 1500 Hz to 3000
Hz, the suppressed leaked sound may basically exceed 10 dB.
Especially within a frequency band from 2000 Hz to 2500 Hz, the
leaked sound may be reduced by more than 20 dB after the sound
guiding hole(s) is opened in an upper side of the housing compared
with a case without opening the sound guiding hole(s).
[0223] It should be noted that the above description of the speaker
is only a specific example and should not be regarded as the only
feasible implementation solution. Obviously, for persons having
ordinary skills in the art, after understanding the basic principle
of the speaker, various modifications and changes may be made in
form and detail of the specific ways and steps of implementing the
speaker without departing from the principle, but these
modifications and changes are still within the scope of the present
disclosure. For example, the hole sizes of the sounding holes 60
may be different in order to suppress the leaked sound in different
wavelengths. All such variations are within the protection scope of
the present disclosure.
[0224] In some embodiments, the speaker described above may
transmit the sound to the user through bone conduction and/or air
conduction. When the air conduction is used to transmit the sound,
the speaker may include one or more sound sources. The sound source
may be located at a specific position of the user's head, for
example, the top of the head, the forehead, a cheek, a temple, an
auricle, the back of an auricle, etc., without blocking or covering
an ear canal. For the purposes of description, FIG. 28 shows a
schematic diagram of transmitting the sound through the air
conduction according to some embodiments of the present
disclosure.
[0225] As shown in FIG. 28, a sound source 2810 and a sound source
2820 may generate sound waves with opposite phases ("+" and "-" in
the figure may indicate the opposite phases). For brevity, the
sound sources mentioned herein may refer to sound outlets of the
speaker that may output sounds. For example, the sound source 2810
and the sound source 2820 may be two sound outlets respectively
located at specific positions of the speaker (e.g., the core
housing or the circuit housing).
[0226] In some embodiments, the sound source 2810 and the sound
source 2820 may be generated by a same vibration device 2801. The
vibration device 2801 may include a diaphragm (not shown in the
figure). When the diaphragm is driven to vibrate by an electric
signal, the front side of the diaphragm may drive the air to
vibrate. The sound source 2810 may form at the sound outlet through
a sound guiding channel 3112. The back of the diaphragm may drive
air to vibrate, and the sound source 2820 may be formed at the
sound outlet through a sound guiding channel 3122. The sound
guiding channel may refer to a sound transmission route from the
diaphragm to the corresponding outlet. In some embodiments, the
sound guiding channel may be a route surrounded by a specific
structure (e.g., the core housing or the circuit housing) of a
speaker. It should to be known that in some alternative
embodiments, the sound source 2810 and the sound source 2820 may
also be generated by different vibrating diaphragms of different
vibration devices, respectively.
[0227] Among the sounds generated by the sound source 2810 and the
sound source 2820, one part may be transmitted to the ears of the
user to form the sound heard by the user. Another part may be
transmitted to the environment to form a leaked sound. Considering
that the sound source 2810 and the sound source 2820 are closer to
the ears of the user, for the convenience of description, the sound
transmitted to the ears of the user may be referred to as a
near-field sound. The leaked sound transmitted to the environment
may be referred to as a far-field sound. In some embodiments, the
near-field/far-field sounds of different frequencies generated by
the speaker may be related to a distance between the sound source
2810 and the sound source 2820. Generally speaking, the near-field
sound generated by the speaker may increase as the distance between
the two sound sources increases, while the generated far-field
sound (the leaked sound) may increase by increasing the
frequency.
[0228] For the sounds of different frequencies, the distance
between the sound source 2810 and the sound source 2820 may be
designed, respectively, so that a low-frequency near-field sound
(e.g., a sound with a frequency of less than 800 Hz) generated by
the speaker may be as large as possible and a high-frequency
far-field sound (e.g., a sound with a frequency greater than 2000
Hz) may be as small as possible. In order to implement the above
purposes, the speaker may include two or more sets of dual sound
sources. Each set of the dual sound sources may include two sound
sources similar to the sound source 2810 and the sound source 2820,
and generate sounds with specific frequencies, respectively.
Specifically, a first set of the dual sound sources may be used to
generate low frequency sounds. A second set of the dual sound
sources may be used to generate high frequency sounds. In order to
obtain more low-frequency near-field sounds, the distance between
the two sound sources in the first set of the dual sound sources
may be set as a larger value. Since the low-frequency signal may
have a longer wavelength, the larger distance between the two sound
sources may not cause a large phase difference in the far-field,
and not form excessive leaked sounds in the far-field. In order to
make the high-frequency far-field sound smaller, the distance
between the two sound sources in the second set of the dual sound
sources may be set as a smaller value. Since the high-frequency
signal has a shorter wavelength, the smaller distance between the
two sound sources may avoid the generation of the large phase
difference in the far-field, and thus the generation of the
excessive leaked sounds may be avoided. The distance between the
second set of the dual sound sources may be less than the distance
between the first set of the dual sound sources.
[0229] The beneficial effects of the present disclosure may include
but are not limited to the following. (1) Different from the prior
art, in the present disclosure, when the hinge arm is rotated
relative to the hinge mount by the external force; a connection of
the first support surface and the second support surface may drive
the support member against the elastic offset of the elastic member
to move in the opposite direction. Therefore, the third support
surface may be switched from elastically abutting on one of the
first support surface and the second support surface to elastically
abutting on the other of the first support surface and the second
support surface. In a section perpendicular to a central axis of
the rotating shaft, a ratio between a maximum distance from the
rotating shaft to the connection and a shortest distance from the
rotating shaft to the first support surface is between 1.1 and 1.5.
When the hinge performs a state switch by a push of the connection,
the hinge may change abruptly in an appropriate level. Thus, the
user may have a relatively obvious feel when puffing the hinge. At
the same time, the change may not be too abrupt to making it
difficult for the user to switch the state of the hinge, thereby
providing convenience for users. (2) The vibration of the housing
and may be reduced and sound leakage may be suppressed. (3) The
sound quality of the speaker may be improved. It should be noted
that different embodiments may have different beneficial effects.
In different embodiments, possible beneficial effects may be any
one or a combination of the above, and may be any other beneficial
effects.
[0230] Having thus described the basic concepts, it may be rather
