DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0021] With reference to FIG. 1, a preferred embodiment of an audio
playing device has a microprocessor (10), a memory (12), a bar code
scanner (20), an audio playing unit (30), a digital to analog
converter (32), a data decompressed unit (31), and a key set (14).
The elements are connected to a common data bus to communicate with
each other.
[0022] The microprocessor (10) has a bar code comparison procedure.
The memory (12) is connected to the microprocessor (10) and is used
to store information generated by a bar code addressing method. The
information has many bar code data of bar codes and multiple
sections of each serial audio signal. The bar code scanner (20) is
connected to the microprocessor (10) to provide bar code data of
the bar codes to the microprocessor (10). The audio playing unit
(30) is connected to the data decompressed unit (31), the digital
to analog converter (32) and the microprocessor (10). The
microprocessor (10) controls operation of the audio playing unit
(30) and outputs a section of the serial audio signal to the audio
playing unit (30) to play.
[0023] With reference to FIG. 2, one implementation of the present
invention includes a main body (101) and the external bar code
scanner (20a). The key set (14) is attached on the main body (101)
and other elements are retained therein. With further reference to
FIG. 3, another implementation of the present invention shows that
the bar code scanner (20b) is a wireless bar code scanner. With
reference to FIG. 4, the bar code scanner (20c) is retained in the
main body (101) to be integrated with the main body (101).
[0024] With reference to FIGS. 1 and 2, since each bar code
corresponds to one 18 specific section of a serial audio signal,
the microprocessor (10) will obtain the bar code data of the
present bar code if the bar code scanner (20a) is shining on the
present bar code. The microprocessor (10) can search and then
output the 1 specific section to the audio playing unit (30) to
play the specific section of the serial audio signal. Therefore,
with further reference to FIG. 5, the operation flow chart of the
present invention has steps of:
[0025] (a) detecting whether the bar code scanner has output any
scanning signal (60), if not, repeating this step until the
scanning signal is input; if yes, the next step will be
executed;
[0026] (b) receiving the bar code data of the scanning signal
(61);
[0027] (c) comparing whether the bar code data conforms to one bar
code data in the memory (62), if not, return to step (a), if yes,
the next step will be executed;
[0028] (d) obtaining a specific section corresponding to the bar
code data (63); and
[0029] (e) playing the specific section (64).
[0030] With reference to FIG. 2, multiple bar codes and contents of
multiple texts corresponding to sections are printed on a paper or
a book, wherein each bar code is corresponded to one specific
section. When bar code scanner (20a) shines on one bar code on the
paper, the main body (101) will play the corresponding specific
section by the audio playing unit (30). Therefore, the main body
(101) can repeat to play the specific section easily and
quickly.
[0031] Further, the key set (14) has multiple function keys (volume
adjusting, stop playing etc functions) attached on the main body
(101). The user can press these function keys to control playing
operation of the audio playing unit (30). To control operation of
the audio playing unit (30) easily, a comparing controlling
function procedure is built in the microprocessor (10) and multiple
bar code data of function bar codes are made to store in the memory
(12). The function bar codes are corresponding to the function keys
of the main body (101). The function bar codes can be printed on a
paper or the like. When the operator using the bar code scanner
(20a) aims at the function bar code on the paper, the
microprocessor (10) executes the comparing controlling function
procedure to determine which function is selected by the operator,
and then controls the audio playing unit (30) according to the
function bar code. Therefore, the operator does not press any
function key to control operation of audio playing unit (30).
[0032] With reference to FIG. 6, another preferred embodiment of
the audio playing device (30) in accordance with the present
invention further has an encryption-decryption unit (11) and a
read-write card unit (40). These elements are also connected to the
data bus to connect to other elements shown in the FIG. 1.
[0033] This preferred embodiment mainly adds a verification
function. The microprocessor (10) further has a verification
procedure and a memory (12) further stores multiple passwords. With
further reference to FIG. 8, since the main body (101) has the
read-write card device (40), the operator has to insert a card into
the read-write card device (40) to have allowance of use of the
audio playing device. With reference to FIG. 7, the operation of
the flow chart of the preferred embodiment has steps of:
[0034] (a) detecting whether the bar code scanner has output any
scanning signal, if not, repeating this step until the scanning
signal is input; if yes, the next step will be executed (70);
[0035] (b) receiving the bar code data of the scanning signal
(71);
[0036] (c) determining whether the password of the card is correct
(72), wherein if the password of the card conforms to one in the
memory, the password is confirmed correct and the next step will be
executed, but if the password is incorrect the flow chart is ended
(73);
[0037] (d) comparing whether the bar code data conforms to one bar
code data in the memory (74), if not, return to the step (a); if
yes, the next step will be executed;
[0038] (e) obtaining a specific section corresponding to the bar
code data (75); and
[0039] (f) playing the specific section (76).
[0040] Based on the second embodiment of the present invention, the
audio playing device can store the sections of many serial audio
signals published from different companies and verified codes
(passwords) for different companies. The operator has to obtain a
card having a verified code of one company to have allowance of use
of the audio playing device.
[0041] With reference to FIGS. 9, 10 and 11, the bar code
addressing method has steps of:
[0042] (a) storing one serial audio signal (80), shown in the wave
signal in FIG. 10;
[0043] (b) separating the serial audio signal to multiple sections
by marking accessing points (AP0-AP3) in the serial audio signal
(81);
[0044] (c) storing multiple accessing points (82);
[0045] (d) generating bar codes corresponding to the accessing
points by one bar code generating method (83), wherein each bar
code is generated by one accessing point, shown in FIG. 11; and
[0046] (e) listing bar codes on a paper (84), shown in FIG. 2.
[0047] The bar code generating method has three different
types:
[0048] 1. Direct-transforming method. The bar code data is the
access point.
[0049] 2. Varied-transforming method. The bar code data is the
access point and security data.
[0050] 3. Encryption-transforming method. The bar code data is the
encrypted access point.
[0051] To suit reading of those types of bar codes, in FIG. 6 the
audio playing device has the encryption-decryption unit. Since the
card stores the type of the bar code, the microprocessor can
determine whether the bar code data from the bar code scanner are
provided to the encryption-decryption unit. The
encryption-decryption unit will read the real access point in the
bar code data and then provides the access point to the
microprocessor.
[0052] At present, some books have a CD or VCD to help readers to
understand the content of the book. Therefore, the bar code can be
further printed on the book, so when the reader reads one paragraph
of content matched to one section of one serial audio signal, the
reader can use the bar code scanner to shine on the bar code to
play the section. Thus the operator can repeat the section quickly
and easily by means of the audio playing device.
[0053] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and function of the
invention, the disclosure is illustrative only. Changes may be made
in detail, especially in matters of shape, size, and arrangement of
parts within the principles of the invention to the full extent
indicated by the broad general meaning of the terms in which the
appended claims are expressed.
