Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] The present application is a Divisional Application of U.S.
patent application Ser. No. 14/388,007, which is a U.S. National
Phase Entry of International Patent Application No.
PCT/KR2012/009489, filed November 9, 2012, which is based upon and
claims the benefit of priority to Korean Patent Applications Nos.
10-2012-0077911, filed on Jul. 17, 2012, and 10-2012-0032209, filed
on Mar. 29, 2012. The disclosures of the above-listed applications
are hereby incorporated by reference herein in their entirety.
TECHNICAL FIELD
[0002] The present disclosure relates to a wired and wireless
earset using an ear-insertion-type microphone, and more
particularly, to a wired and wireless earset using an
ear-insertion-type microphone that enables listening to
good-quality sound by blocking external noise when providing voice
signals that are provided through the ear to the other end or when
controlling a voice recognition device, allows effective calls in a
noisy environment by increasing a recognition rate of the voice
recognition device and controls a microphone and/or a speaker
depending on signals received from an external device.
RELATED ART
[0003] Generally, an earset is used being worn on a user's ear
while it is wire or wireless connected with an external device
(e.g. mobile devices such as a portable media player, mobile
communication terminal, smartphone, etc.) for the purpose of
listening of a sound or communication of voice signals.
[0004] However, users find it difficult to communicate with the
other side in a noisy or stormy environment since traditional
earsets are exposed to the outside, and the distance between a
speaker and a microphone must be constantly maintained so as to
prevent oscillation; thus it is hard for traditional earsets to be
downsized.
[0005] In detail, the earset comprises a connector combined with an
external device, a control portion electrically connected with the
connector that sets up user modes of the earset and controls
general motions of the earset, and a phone means electrically
connected with the control portion, being worn on a user's ear,
that performs voice output or voice input.
[0006] Prior arts are disclosed in the Korean Patent Application
No. 10-2000-0018098 (Insert microphone/circumaural type microphone)
and 10-2001-0088886 (Audio signal input/output device and
earphoneemploying microphone) and the Korean Patent No. 10-1092957
(Microphone) and 10-1109748 (Microphone).
[0007] However, traditional earsets using the prior arts do have
echo or howling since, when a user communicates with the other side
via a phone, the voice of the other side comes out of speakers and
enters again into a microphone, thus making it hard to deliver a
voice clearly.
[0008] Moreover, when a user listens to music or watches a movie, a
user's voice enters into a microphone and comes out of speakers
since the microphone is arranged either at one side of ears or both
ears for the purpose of outputting stereo sounds to both ears, thus
hindering the user from listening sounds clearly.
TECHNICAL ISSUE
[0009] To resolve the issues presented above with the necessity of
technical development, the present disclosure is invented. A
purpose of the present disclosure is to provide a wired and
wireless earset using an ear-insertion-type microphone with a
quality of sound even in a noisy environment.
[0010] Another purpose of the present disclosure is to provide a
wired and wireless earset using an ear-insertion-type microphone
with clear sound by blocking external noise with an echo offset
means in the case of sending voice messages to the other side so as
to block echo or howling effect, or by outputting a constant
quality of stereo sound in the case of playing a song.
[0011] Furthermore, another purpose of the present disclosure is to
provide a wired and wireless earset using an ear-insertion-type
microphone that, in order to prevent echo during a phone call by
figuring out manually or automatically whether it is either on
calling or playing a song, adjusts at least one of the following:
speaker output or microphone reception.
[0012] Yet another purpose of the present disclosure is to provide
a wired and wireless earset using an ear-insertion-type microphone
that is easy to control in a noisy environment by blocking external
noise in the case of controlling a voice recognition device by
voice signals provided via the ear so as to enhance recognition of
the voice recognition device.
[0013] Still another purpose of the present disclosure is to
provide a wired and wireless earset using an ear-insertion-type
microphone that is applicable to both wired earphones and wireless
earphones, and that enables a user to select microphone switches
manually or automatically, thus increasing user's satisfaction.
[0014] However, a purpose of the present disclosure is not
construed to be limited only to the purposes described above, and
with the descriptions below, another purpose not presented herein
is clearly understood by one of ordinary skill in the art to which
the present disclosure belongs.

wherein the earset is worn only on one ear of a user.
EFFECTS OF INVENTION
[0018] As described above, according to an earset of the present
disclosure, since the arrangement of speakers and microphones are
unified, a user can have a call with the other side with clearance
even in a noisy or stormy environment thus enhancing user
convenience. That is, in a noisy environment, an earset is worn on
an external auditory canal of a user so as to provide voice signals
with no surrounding noise of the user to an external device, thus
making a clear calling with the other side and, by applying the
same technology to voice recognition devices, increasing voice
recognition.
[0019] Furthermore, in an environment with weak noise, the earset
provides voice signals provided from user's mouth into external
devices, thus reducing a nasal tone that occurs when a user makes a
phone call using a microphone of an earphone portion worn on an ear
and resolving low volume at the same time.
[0020] Furthermore, since it collects sound from both ears through
microphones arranged at both earphone portions, the earset easily
amplifies voice signals with no additional amplifier, thus reducing
inconvenience with low volume during a phone call.
[0021] Furthermore, by using an echo offset means, the earset
provides voice signals provided via the ear to the other side and,
when controlling a voice recognition device, blocks external noise,
thus blocking echoing or howling effect.
[0022] Furthermore, the earset adjusts at least one of either
speaker output or microphone reception, thus blocking external
noise so as to block echoing or howling effect.
[0023] Furthermore, not only during a call but also during a
receiving and listening of music, the earset outputs stereo sound
into both ears, thus maintaining the quality of sound output.

[0039] A wired and wireless earset using ear-insertion-type
microphone will be described more fully hereinafter with reference
to the accompanying drawing, in which some embodiments are shown.
Advantages and features of some embodiments accomplishing the same
are hereafter detailed with reference to the accompanying
drawings.
[0040] However, a wired and wireless earset using
ear-insertion-type microphone is embodied in different forms and

[0042] A detailed description of the wired and wireless earset
using ear-insertion-type microphone is hereafter presented with
reference to the accompanying drawings. The same reference numbers
indicate the same component throughout the specification.
[0043] For an example, a speaker and a microphone equipped at a
first earphone portion 110 is described as a first speaker S1, 310
and a first microphone M1, 410 respectively; a speaker and a
microphone equipped at a second earphone portion 120 as a second
speaker S2, 320 and a second microphone M2, 420 respectively; and a
microphone equipped at a main body 200 as a third microphone M3,
430.
[0044] FIG. 1 is a first embodiment of the earset connected wherein
it is wireless connected with an external device.
[0045] As shown in FIG. 1, the earset contains an earphone portion
100 and a main body 200.
[0046] Herein, the earphone portion 100 contains a first earphone
portion 100 inserted into user's first external auditory canal and
a second earphone portion 120 inserted into user's second external
auditory canal, wherein the first earphone portion 110 and the
second earphone portion 120 are connected with a main body 200 with
a wire.
[0047] A first speaker 310 that outputs sound or voice signals
provided from external device (not present) such as a mobile phone
or an MP3 player is equipped at the first earphone portion 110, and
a second microphone 420 that receives user's voice signals provided
from user's external auditory canal is equipped at the second
earphone portion 120.
[0048] For the second microphone 420, it receives signals generated
from user's ear during his or her speaking, and it is preferred to
be composed with directional microphone.
[0049] The main body 200 is connected with an external device (not
presented) wirelessly, containing a signal transceiving portion 210
that transceives signals with external devices; and a control
portion 220 that transmits voice signals received from the first
microphone 410 into the external device via the signal transceiving
portion 210 and outputs the received voice signals from the
external devices via the signal transceiving portion 210 into the
first speaker 310.
[0050] The earset further contains a volume controlling portion
(not presented) that controls volume and a call button portion (not
presented) that determines whether to have a call.
[0051] Moreover, the control portion 220 further contains a
function of transmitting user's voice signals received from the
second microphone 420 via the signal transceiving portion 210 into
a voice recognition device (not presented).
[0052] FIG. 2 is a second embodiment of the earset, wherein it is
wire connected with an external device.
[0053] As shown in FIG. 2, if the main body 200 is wire connected
with an external device (not presented) via a connector 500, a
signal transceiving portion 210 is removed from the composition of
the first embodiment.
[0054] Herein, the control portion 220 further contains a function
of direct transmitting of user's voice signals received from the
second microphone 420 into a voice recognition device (not
presented).
[0055] FIG. 3 is a third embodiment of the earset.
[0056] As shown in FIG. 3, in addition to the composition of the
first embodiment, the earset further contains a third microphone
430 that receives voice signals provided from a user's mouth; and a
microphone switch 230 to select either the second microphone 420 or
the third microphone 430.
[0057] The microphone switch 230 selects the second microphone 420
if a level of detected noise signal under the control of the
control portion 220 is the predetermined level or exceeds it, and
it selects the third microphone 430 if the level is below the
predetermined level. Moreover, it also selects a microphone in
accordance with a detection level of a user of an external
device.
[0058] For an example, a control portion 220 controls the
microphone switch 230 so as to select the second microphone 420 if
the predetermined level of noise signals preset by a designer or
user of the earset reaches or exceeds a predetermined value (for
instance, 70 dB) and select the third microphone 430 if the
predetermined level is below that predetermined value. Thus, a user
of the earset makes a call with convenience regardless of
surroundings.
[0059] Herein, a designer or user of the earset sets the level of
noise in a various way following his or her selection.
[0060] The microphone switch 230 is manually controlled by a user,
and in order for the microphone switch 230 to operate automatically
by the criteria above, the main body 200 has a voice recognition
sensor or a motion recognition sensor and the microphone switch 230
operates automatically according to an output signal of a voice
recognition sensor or a motion recognition sensor.
[0061] The third microphone 430 is exposed to the outside of the
main body 200 so as to receive voice signals provided from a user's
mouth, and in some embodiments, it is composed of an
omnidirectional microphone.
[0062] If the earset is applied to voice recognition devices such
as mobile phones, robots, navigations and industrial machinery, a
function of transmitting user's voice signals received from the
second microphone 420 into a voice recognition device (not
presented) via the signal transceiving portion 210 is further
contained to the earset. Therefore, the earset controls a voice
recognition device by exploiting a user's voice from the ear.
[0063] FIG. 4 and FIG. 5 are a fourth embodiment of the earset.
[0064] As shown in FIG. 4, the first earphone portion 110 further
contains a first speaker 310 and a first microphone 410, and the
second earphone portion 120 further contains a second speaker 320
that outputs sound signals or voice signals provided from external
devices.
[0065] Herein, since an output of the first speaker 310 is
transmitted as an input of the first microphone 410, an echo effect
occurs when a user makes a call with the other side. To reduce the
echo effect, an output adjusting circuit (not presented) is further
contained. Moreover, the echo effect is prevented as well as
external noise is blocked by adjusting reception of the first
microphone 410. Also, to have the same effect, an output of the
first speaker 310 and reception of the first microphone 410 can be
adjusted at the same time.
[0066] Meanwhile, the earphone portion 110 or the main body 200
further contains an echo offset means 240, FIG. 8 that reduces the
echo factor included among the signal received from the first
microphone 410.
[0067] As shown in FIG. 9, the echo offset means 240 contains a
filtering portion 242 that receives and filters sound signals or
voice signals provided from external devices to a first speaker
310, a phase inversion portion 244 that reverses sound or voice
signals filtered and outputted from the filtering portion 242, and
a signal synthesizing portion 246 that synthesizes sound or voice
signals outputted from the phase inversion portion 244 in a
phase-reversal way and inputted from the first microphone 410.
[0068] As shown in FIG. 5, if the main body 200 is wire connected
via a connector 500 with an external device (not presented), a
signal transceiving portion 210 is removed from the fourth
embodiment in FIG. 4.
[0069] Herein, the control portion 220 further contains a function
of direct transmitting of user's voice signals received from the
first microphone 410 into a voice recognition device (not
presented).
[0070] FIG. 6 is a fifth embodiment of the earset.
[0071] As shown in FIG. 6, the first earphone 110 includes a first
microphone 410 and a first speaker 310, and a second earphone 120
includes a second microphone 420. The main body 200 includes a
third microphone 430 to received voice signals provided from a
user's mouth.
[0072] In the composition above, the control portion 220 detects
noise signals, and if the detected level of noise signals is higher
than the predetermined level, it selects the first microphone 410
and the second microphone 420, and if the detected level of noise
signals is lower than the predetermined level, it selects the third
microphone 430. Moreover, it also selects a microphone in
accordance with a detection level of a user of an external
device.
[0073] Since the earset collects sound from both ears through
microphones arranged at both earphone portions, the earset easily
amplifies voice signals with no additional amplifier, thus reducing
inconvenience with low volume during a phone call.
[0074] Furthermore, by controlling an output of the first speaker
310 through an external circuit, the earset prevents echoing
effects, thus enabling a call even in a noisy environment. Also, a
user adjusts reception of the first microphone 410 and second
microphone 420, thus preventing echoing effects.
[0075] In some embodiments, an output of the first speaker 310 is
also controlled by a variable resistor or a fixed resistor.
[0076] Also, a user prevents echoing effects by automatically or
manually adjusting at least one of the following: an output of the
first speaker 310, the first microphone 410 or the second
microphone 420.
[0077] FIG. 7 is a sixth embodiment of the earset.
[0078] As shown in FIG. 7, in addition to the composition of the
fifth embodiment, the earset further contains a second speaker 320
on the second earphone portion 120 that outputs sound or voice
signals provided from external devices.
[0079] FIG. 8 is a seventh embodiment of the earset, and FIG. 9 is
an embodiment that illustrates an echo offset means.
[0080] As shown in FIG. 8, in addition to the composition of the
fifth embodiment, the earset further contains an echo offset means
240 on the first earphone portion 110 that reduces an echo factor
included among voice signals received from the first microphone
410.
[0081] As shown in FIG. 9, the echo offset means 240 contains a
filtering portion 242 that receives and filters sound signals or
voice signals provided from external devices to a first speaker 310
and the second speaker 320, a phase inversion portion 244 that
reverses sound or voice signals filtered and outputted from the
filtering portion 242, and a signal synthesizing portion 246 that
synthesizes sound or voice signals outputted from the phase
inversion portion 244 in a phase-reversal way and inputted from the
first microphone 410. Also, the echo offset means can be separately
arranged at each earphone portion.
[0082] Also, in order to prevent echoing, a user can adjust an
output of a first speaker 310 and a second speaker 320 or can
adjust reception of a first microphone 410 and second microphone
420.
[0083] FIG. 10 is an eighth embodiment of the earset.
[0084] In the first embodiment and the seventh embodiment, the
earphone portion 100 is separated into a first earphone portion 110
and a second earphone portion 120 and they are each worn on each
side of ears. However, as shown in FIG. 10, it is also possible
that a first speaker 310 and a first microphone 410 are equipped at
one earphone portion 100 so that they are worn only on one ear.
[0085] In the case above, the earphone portion 100 is preferred to
be connected with an external device in a wired or wireless
way.
[0086] Also, it is noted that technical ideas of the third
embodiment or the seventh embodiment described above are apparently
addable to the eighth embodiment.
[0087] In an earset having the composition of the eighth
embodiment, an earphone portion 100 contains a first speaker 310
and a first microphone 410, wherein the first speaker and the first
microphone 410 of the earphone portion 100 are unified and are
inserted into a user's external auditory canal, a user thus
speaking and listening through the inserted earphone portion 100.
That is, a first speaker 310 and a first microphone 410 are in the
ear so that external noise does not come into a first microphone
410, thus making a user have a call in a noisy environment or a
stormy weather and also enabling the user to have both hands
available, thus enhancing user's work productivity. Also, in order
to prevent echoing, a user can exploit methods presented in the
fourth and seventh embodiments. Furthermore, in the eighth
embodiment, a third microphone (not presented) is arranged at the
outside so that a user chooses a microphone according to a level of
noise signals.
[0088] FIG. 11 is a ninth embodiment of the earset.
[0089] As shown in FIG. 11, a wireless earset ear-insertion-type
microphone contains an earphone portion 100 and a main body 200.
The earphone portion 100 contains a first speaker 310, a first
earphone portion 110 that includes a first microphone 410 and is
inserted into user's ear, and a second earphone portion 120 that
includes a second speaker 320 and is inserted into user's ear.
[0090] The main body 200 includes a signal transceiving portion 210
that transceives sound signals with external devices, a control
portion 220 that transmits voice signals received from a first
microphone 410 and outputs sound signals received from external
devices via the signal transceiving portion 210 into a first
speaker 310 and a second speaker 320, and a mode setting portion
that controls a calling mode and a playing mode.
[0091] An embodiment presented in FIG. 11 contains a microphone
only in an earphone portion inserted into one side of ears. The
earphone portion 110 includes a first microphone, and the first
earphone portion 110 and the second earphone portion 120 contains
speakers 310 and 320. A first earphone portion 110 including the
first microphone 410 is inserted into either one side of human
ears, and a second earphone portion is inserted into the other
side.
[0092] The first earphone portion 110 contains a first speaker 310
and a first microphone 410, and a first speaker 310 and a first
microphone 410 of a first earphone portion 110 are unified and
inserted into a user's external auditory canal. A user speaks and
listens through the earphone portion inserted into his or her ear.
That is, since the speaker and microphone are in the ear and thus
blocking external noise from coming into the microphone, a user can
have a call even in a noisy environment and his or her hands are
both available, therefore work productivity increases.
[0093] Herein, the speaker 310 and 320 are dynamic speakers, and in
some embodiments, a closed-type balanced armature receiver and/or a
piezoelectric pressure speaker are used. Also, it is preferred for
the first microphone 410 to have a directional microphone component
that is resistible to noise. Given that the first microphone 410
receives signals generated from the ear during a user's speech, it
is preferred for it to have a directional microphone, though it is
also possible to use an omnidirectional microphone.
[0094] Also, the externality of an earphone portion blocks noise
generated by collision of winds with the earphone portion 110 and
120, and the externality of an earphone is made of silicon for
waterproofing of the earphone portion 110 and 120.
[0095] The signal transceiving portion 210 is a portion that
transceives signals with external devices. For an example, the
transceiving portion 210, using the Bluetooth communication,
transceives music signals and voice signals with external devices
such as a mobile telecommunication terminal.
[0096] The control portion 220 controls earphone portions 110 and
120 and a signal transceiving portion 210. Basically, the control
portion 220 transmits voice signals inputted into a first
microphone 410 to an external device, delivers music signals to
speakers 310 and 320, and controls the delivering of the voice
signals received from the external device to a second speaker
320.
[0097] In some embodiments, the main body 200 includes a
controlling device and a device that turns on and off an output of
the earset. Furthermore, the earset contains a call button that
determines whether to call to an external device such as a mobile
telecommunication terminal.
[0098] A control portion of the earset controls at least one of the
following: a first speaker 310 or a first microphone 410 included
in a first earphone portion 110.
[0099] In the present disclosure, a calling mode is a mode that
operates when a user makes a call with the other side via an
external device such as a mobile telecommunication terminal, and a
playing mode is a mode that operates when a user listens to a song
or watches a video via an external device such as a mobile
telecommunication terminal.
[0100] To play a video using a mobile telecommunication terminal, a
constant stereo sound quality matters. Since the earset contains a
first microphone 410 and a first speaker 310 in an earphone portion
110, with no additional control otherwise, an echoing or a howling
effect occurs during a call because a voice outputted to a speaker
310 is inputted into a first microphone 410.
[0101] To prevent the echoing or howling, an output of a first
speaker 310 or reception of a first microphone 410 is reduced,
wherein an output adjusting circuit is inserted into a speaker's
output terminal in order to reduce an output of the first speaker
310. However, it diminishes the low bandwidth during a playing of
music, thus restricting the listening of music. Resolving this
issue, a changeover switch is used so that in a playing mode an
output of a first speaker 310 does not pass through an output
adjusting circuit 252.
[0102] In order to resolve the issue, the control portion 130
controls at least one of the following: a first speaker 310 or a
first microphone 410. If it controls them at the same time, it
blocks the first speaker 310 and enables the first microphone 410
to input a voice.
[0103] A function of the control portion 220 and mode setting
portion 250 to control a calling mode and a playing mode is figure
out a calling or playing status manually or automatically so as to
control at least one of the following: a first speaker 310 or a
first microphone in the earphone portion 110. Also, the function of
the control portion 220 and the mode setting portion 250 is
equipped by an external device such as user's smartphone.
[0104] In the present disclosure, the mode setting portion 25 is
composed as shown in FIG. 12 so that a user makes a call clearly in
a calling mode and listens to music with quality in a playing mode.
Meanwhile, the control portion 220 and the mode setting portion 250
are interchangeable in their arrangement, and a wired earset does
not necessarily have a signal transceiving portion 210.
[0105] Regarding a switch 251 in FIG. 12, in a calling mode,
terminal 2 is connected with terminal 1, and terminal 5 with
terminal 4. Also, in a playing mode, terminal 2 is connected with
terminal 3, and terminal 5 with terminal 6.
[0106] Since terminal 1 of the switch 251 and a first speaker 310
are connected by a speaker output adjusting circuit 252, if the
switch 251 is a calling mode, an output of a speaker passes through
the speaker output adjusting circuit 252 and is outputted from a
first speaker 310, and if the switch 251 is a playing mode, an
output of a speaker is directly outputted from a first speaker 310
with no pass via the speaker output adjusting circuit 252. Herein,
it is preferred for the speaker output adjusting circuit 252 to be
composed with resistors. Meanwhile, when an output level of an
external device such as a mobile telecommunication terminal is
below the predetermined level, a speaker output adjusting circuit
252 is unnecessary since, if an output level of an external device
is higher than the predetermined level, an output of a first
speaker 310 is also high and is delivered to a first microphone,
thus making an echo effect during a call.
[0107] For an output of a speaker to be delivered to a first
speaker well, a speaker matching circuit composed of circuit R, L
and C is further equipped between terminal 3 of the switch 251 and
a first speaker 310.
[0108] For the same purpose above, an additional speaker matching
circuit composed of circuit R, L, and C is further equipped at the
second speaker 320, and it is noted that an additional speaker
adjusting circuit to adjust an output of the second speaker 320 is
further equipped.
[0109] Given a speaker output adjusting circuit and a speaker
matching circuit is further equipped as described above, in a
calling mode the volume of a first speaker 310 is lower than the
volume of a second speaker 320, and the volume in a calling mode is
lower both at the first speaker and the second speaker, since an
output is adjusted in order to prevent the volume of the first
speaker 310 from being inputted into the first microphone 410 and
the volume of the second speaker 320 is adjusted in order to make
balance with the first speaker 310.
[0110] In the end, a speaker output adjusting circuit and a speaker
matching circuit perform an adjusting of the balance of left and
right and an output of a quality of sound.
[0111] Furthermore, a call button 254 is connected with terminal 4
of the switch 251 so that a user operates it in a calling mode.
[0112] Furthermore, for an input of a microphone 410 to be
delivered to the other side well, a microphone matching circuit 255
is equipped between terminal 4 of the switch 251 and a first
microphone 410. Herein, for the microphone matching circuit 255 it
is preferred to be composed of circuit R, L, and C including a
zener diode, wherein the zener diode performs a function of
protecting a first microphone 410.
[0113] Also, terminal 6 of the switch 251 is connected with dummy
resistors 256. If terminal 5 of the switch is disconnected from
terminal 4, that is, if the first microphone receives no input
signal, since a microphone equipped at an external device such as a
smartphone operates, the dummy resistors should be equipped so that
the external device such as a smartphone recognizes that the first
microphone 410 is still connected.
[0114] Unless the dummy resistors 256, if a user makes a call in a
playing mode, a microphone equipped at an external device such as a
smartphone operates, thus making impossible a call with the other
side. Due to the dummy resistors 256, however, the dummy resistors
256 are recognized as an external microphone at an external device
such as a smartphone, thus preventing the microphone from
operating. Therefore, since a user's voice is not transmitted to
the other side, he or she makes a call after changing a playing
mode into a calling mode.
[0115] In this embodiment, the earset automatically or manually
changes a playing mode to a calling mode by using a switch or voice
recognition function or sensor or application, thus enabling to
call with the other side through a microphone 410.
[0116] Therefore, in a playing mode the first microphone 410 does
not operate, and if a user listens to music then a volume of an
output of a speaker decreases. To make a call using a microphone at
an external device such as a mobile telecommunication terminal
during a playing mode, one just needs to remove dummy resistors
256.
[0117] Meanwhile, as shown in FIG. 13, instead of dummy resistors,
a second microphone 420 is connected with terminal 6 of the switch
251. Herein, the second microphone 420 is arranged at a main body
200 in FIG. 1 or between earphone portion 110, 120 and the main
body 200. In FIG. 13, there are a noisy mode and a normal mode,
where in a noisy mode than a normal mode, when a user listens to a
song, the volume of a first speaker 310 is comparatively lower than
the volume of a second speaker 320, and both the volumes of the
first speaker 310 and second speaker 320 in a noisy mode are lower
than the volumes in a normal mode, since an output adjusting
circuit is needed in order to prevent echoing and howling, thus
outputting the low volume of sound. However, when a signal
outputted from an external device such as a mobile
telecommunication circuit 252 is below the predetermined level, a
speaker output adjusting circuit 252 is unnecessary. Meanwhile,
FIG. 12 and FIG. 13 are different in that instead of dummy
resistors 256, a second microphone, that is an external microphone,
is electrically connected. Therefore, a calling mode in FIG. 12 and
a playing mode is a noisy mode and a normal mode in FIG. 13
respectively. Therefore, it is preferred that every description of
mode change regards a calling mode as a noisy mode, and a playing
mode as a normal mode
[0118] In FIG. 13, in a noisy environment, a user makes a call with
the other side by using a switch or a voice recognition function or
a sensor or an application via a first microphone 410 in the ear,
automatically or manually changing a normal mode into a noisy mode,
and in a quiet atmosphere, a user makes a call conveniently with a
second microphone 420 in the externality by automatically or
manually changing a noisy mode into a normal mode. Meanwhile, a
second speaker 320 is presented in FIG. 12 and FIG. 13, which is an
additional composition necessary for listening to music in a stereo
sound quality. In other words, for a simple call with the other
side, a second speaker 320 is unnecessary. Furthermore, if an
external device is a radio transceiver, since it is only necessary
for a call, a second speaker is unnecessary.
[0119] FIG. 14 is a tenth embodiment of the earset.
[0120] Although the composition in FIG. 14 is mostly equal with the
composition in FIG. 11, an electromagnetic wave filtering portion
150 is further equipped on a wire portion that connects with an
earphone portion 100 and a main body 200. The electromagnetic wave
filtering portion 150, as shown in FIG.14, is arranged on a lead
wire L, or is arranged at earphone portions 110 and 120.
[0121] For the electromagnetic wave filtering portion 150, various
forms of an electromagnetic interception device that those skilled
in the art applies to are used.
[0122] For an instance, in some embodiments, an electromagnetic
interception device such as the Korean Utility Model Registration
No. 20-0317093 "Electromagnetic waves interception equipment for
mobile communication equipment earphone" is used. A choke filter is
installed at a high frequency entrance on a lead wire linked to
earphone portion, thus blocking electromagnetic waves. Regarding
this electromagnetic interception device, even if an
electromagnetic wave received into an antenna is synchronized at a
communication device, since the high frequency flowed into a lead
wire of an earphone portion is blocked at the choke filter,
electromagnetic waves are not induced into the earphone
portion.
[0123] A composition presented at the right side in FIG. 14 is an
enlarged image of circuit structure of an electromagnetic wave
filtering portion 260. An RF filter (Low pass filter) as a choke
filter is installed at a high frequency entrance of a lead wire L.
In detail, the RF filter connects coil inductors L1, L2 and L3 to
lead wires connected with a first microphone M1, a first speaker S1
and a second speaker S2 at an earphone portion, and it connects
condensers C1, C2 and C3 between lead wires. By blocking a high
frequency component from passing towards earphone portions E1 and
E2 by means of coil inductors L1, L2 and L3, a user makes a call
and listens to a quality of music. Meanwhile, it is noted that a
choke filter is able to be substituted for other compositions that
perform the same functions those skilled in the art are expected to
know.
Mode Setting and Control
[0124] A control in accordance with a calling mode (noisy mode) and
a playing mode (normal mode) is described more fully hereinafter. A
mode control that will be described below is performed at a control
portion 220 a mode setting portion 250 in FIG. 11. Depending on a
wired or wireless earset, the control portion 220 or mode setting
portion 250 is arranged between external devices such as mobile
telecommunication terminals or at an external device.
[0125] A manual mode is where a user manually determines a calling
mode (noisy mode) or a playing mode (normal mode) through an extra
switch or voice recognition or a motion sensor, whereas an
automatic mode is where a control portion 220 or a mode setting
portion 250 sets up a calling mode (noisy mode) or a playing mode
(normal mode) according to environments. Descriptions of how a
manual mode or an automatic mode operates will be presented, that
is, how a mode action proceed in accordance with what order or
which setting.
First Embodiment of Mode Action
[0126] A control portion 220 or a mode setting portion 250 is
basically controlled as a manual mode. In other words, a user of
the earset selects a calling mode or playing mode. Though not
presented in drawings, a mode action is manipulated by at least one
of among a switch, voice recognition and a motion sensor arranged
at a main body 200. If there is no selection by a user, the earset
operates as a preset mode. Moreover, a mode is manually set up
through an application run on a mobile telecommunication
terminal
Second Embodiment of Mode Action
[0127] A user might preset the earset to operate as a manual mode
or an automatic mode. Herein, the mode is also set up by a switch,
voice recognition or a motion sensor to choose a manual mode or an
automatic mode. Also, the mode is set up through an application
installed on a mobile telecommunication terminal
[0128] If it is set up as a manual mode, the earset waits for an
input of a user as shown in the first embodiment of a mode action,
or it operates as a preset mode. If it is set up as an automatic
mode, the earset operates as an automatic mode. Setting a manual
mode or an automatic mode is called a first mode setting.
Third Embodiment of Mode Action
[0129] When a sound signal is delivered to earphone devices, if
there is a manipulation of a user to the earset, the earset
operates as a manual mode and if not, it operates as an automatic
mode. Also, even in an automatic mode, if a user manually operates
the earset, in accordance with the operation of a user, it operates
as a calling mode or a playing mode. Distinguished from the second
embodiment, a selection or setting of a playing mode or calling
mode is called a second mode setting.
[0130] In a manual mode, the earset operates in accordance with
user's inputs, yet it is noted that the earset operates in another
way. A few embodiments will be described hereinafter.
First Embodiment of Manual Mode
[0131] As the most basic manual mode, a user selects a calling mode
or a playing mode through an interface of a mobile
telecommunication terminal linked with external terminals such as a
switch, or an external device.
Second Embodiment of Manual Mode
[0132] When a user inputs a specific voice command via a first
microphone 410 of the earset, the microphone recognizes the voice
and an earphone device operates as a calling mode or a playing mode
according to a voice command For an example, if a user inputs
"call" then a calling mode operates, and if a user inputs "play"
then a playing mode operates.
Third Embodiment of Manual Mode
[0133] Through a specific operating sensor at the earset or a
mobile telecommunication terminal, a calling mode or a playing mode
is determined For an instance, using gyro sensors, a user
determines a calling mode or a playing mode by shaking his or her
mobile telecommunication terminal with a constant number or moving
with a specific shape. It is apparent that those skilled in the art
determines a calling mode or playing mode with various sensors
available to them.
[0134] Meanwhile, when a user pushes a call button arranged at a
mobile telecommunication terminal or a main body of the earset due
to a phone call during his or her listening to a music (a playing
mode), a control portion controls the change of the playing mode
into a calling mode with a call connection. Though an input means
separated from a call button for changing into a calling mode is
addable to the earset, it is preferable for a call button to make a
call connection and change into a calling mode, since for a user it
is cumbersome to input again for changing into a calling mode after
pushing a call button and it might cause an echoing effect.
[0135] Meanwhile, the embodiments described above in the manual
mode is able to be set up or operated by user's manipulation via
applications run on a mobile telecommunication terminal.
[0136] Embodiments of an automatic mode will be described more in
detail. In the description below of an automatic mode, it is
assumed that a control portion 220 takes a control of the whole
earset. Also, an automatic mode is controllable by the mode setting
portion 250.
First Embodiment of Automatic Mode
[0137] During a calling or playing a song, a mobile
telecommunication terminal has its own identification number or
code. For an example, it has an identification code 001 (that is, a
sign for a calling status) during a calling and an identification
code 002 (that is, a sign for playing a song). Although those
identification signs or codes is not necessarily coincident in
every mobile telecommunication terminal, identification codes
defined as specific actions are fixed in each terminal device. The
first embodiment represents an exploit of identification signals or
codes. When a mobile telecommunication terminal, an external
device, is on operation of calling, it transceives voice signals
with a signal trasnceiving portion 210, whereas the signal
trasnceiving portion 210 receives the identification signals or
identification codes. If code 001 is received in accordance with
the identification signals or identification codes, a control
portion 220 controls the earset device in accordance with the
calling mode. In other words, in a calling mode an output of a
first speaker is blocked, and a first microphone 410 receives voice
and a second speaker 320 outputs the voice of the other side. If
code 002 is received, a control portion 220 controls the earset
device in accordance with the playing mode. In a playing mode,
sound is outputted from all speakers 310 and 320, thus letting a
user enjoy stereo sound.
Second Embodiment of Automatic Mode
[0138] With the increasing of smartphones, there are a variety of
mobile telecommunication terminals equipped with various functions.
Smartphones perform many functions via each application. Voice
calls, MP3 music plays or video plays are all performed via
separated applications. When applications operate, as described in
the first embodiment, each identification signal or identification
code is generated. Therefore, a control portion 220 receives
signals generated by the operation of applications, thus
controlling the earset to operate as a calling mode or a playing
mode.
Third Embodiment of Automatic Mode
[0139] Furthermore, an application for controlling the earset is
installed on a smartphone, and the earset is controlled by a
control application. That is, a control portion 220 does not
control performance of a calling mode or a playing mode but a
control application analyzes to decide whether to perform a calling
mode or a playing mode and, by sending the result of the analysis,
it performs a calling mode or a playing mode.
Fourth Embodiment of Automatic Mode
[0140] In another embodiment, a control portion 220 analyzes sound
signals received into the earset device, and based on the result,
sets up a calling mode or a playing mode. Sound signals have two
types: voice signals or sound music signals. Voice signals are
merely composed of conversations of human speech, and music signals
are signals generated when music is played.
[0141] Sound is physically represented as a waveform. Signal
frequency, wave height or wave pattern is analyzed. In this
embodiment, by analyzing them, one can distinguish sound signals
from music signals.
[0142] It is obvious for those skilled in the art to perform in a
various way an analysis of frequency height, change and regularity
within a specific interval of sound signals in order to distinguish
sound signals from music signals. For an instance, sound signals
are distinguished from music signals in accordance with whether an
average of frequency change disclosed in the Korean Patent
Publication 10-2010-0098100 exceeds a threshold.
[0143] A control portion 220 distinguishes sound signals (noisy
environment) and music signals (quiet environment) and determines a
setting of a calling mode (noisy mode) or a playing mode (music
mode). Furthermore, as described in the third embodiment, by an
application run on a smartphone, it decides if sound signals
outputted from a smartphone are sound signals or music signals and
sends the result to the earset so as to control an automatic
mode.
[0144] FIG. 15 is a flowing chart of the earset.
[0145] Mode action 1, mode action 2 and mode action 3 each
represents the order of execution of the described modes in
accordance with the embodiments. A manual mode and automatic mode
is marked as a box of dotted lines. A dotted line box on the left
in FIG. 13 represents a manual mode, whereas a box on the right is
an automatic mode. Meanwhile, descriptions for FIG. 15 follow the
descriptions for FIG. 12, which also applies to FIG. 13. In other
words, a calling mode and a playing mode in FIG. 12 are
correspondent to a calling mode and a playing mode in FIG. 13.
[0146] Mode action 1 is a selection with no automatic mode where a
user manually selects a calling mode or a playing mode.
[0147] In mode action 2, the earset operates in accordance with a
user's predetermined setting. Thus, a decision step S2 whether a
preset mode after external device's signals are received (S1) is
manual or automatic is needed. A preset mode operates in accordance
with the decision. If a user does not choose a first mode while the
preset mode is a manual mode (a first mode), a second mode that was
set up just before operates.
[0148] In mode action 3, if a user chooses either a calling mode or
a playing mode (second mode) after external device's signals are
received (S1), a manual mode is activated and executes the mode, or
if there is no input from a user, an automatic mode operates.
During an operation of an automatic mode, if a user manually
selects a playing mode or calling mode (S4), the mode is changed
into a manual mode, or if there is no input from a user, it
continually operates as an automatic mode.
[0149] Automatic mode is described herein more in detail. As
described in the embodiments of an automatic mode, a mode analysis
is performed in a various way. If the received signals are decided
music signals (quiet environment), the earset operates as a playing
mode (normal mode) through a control portion 220. On the contrary,
if the received sound signals are decided voice signals (noisy
environment), the earset operates as a calling mode (noisy mode)
through a control portion 220.
[0150] In concluding the detailed description, those skilled in the
art will appreciate that many variations and modifications can be
made to the preferred embodiments without substantially departing
from the principles of the some embodiments described above.
Therefore, the described some embodiments are used in a generic and
descriptive sense only and not for purposes of limitation.
