FIG. 11 is a schematic view of the generating multiple bar codes of the serial audio signal when the bar code addressing method is executed. - 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. - 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.
- With reference to
FIG. 2 , one implementation of the present invention includes a main body (101) and the external bar code scanner (20 a). The key set (14) is attached on the main body (101) and other elements are retained therein. With further reference toFIG. 3 , another implementation of the present invention shows that the bar code scanner (20 b) is a wireless bar code scanner. With reference toFIG. 4 , the bar code scanner (20 c) is retained in the main body (101) to be integrated with the main body (101). - 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 (20 a) 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 toFIG. 5 , the operation flow chart of the present invention has steps of: - (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;
- (b) receiving the bar code data of the scanning signal (61);
- (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;
- (d) obtaining a specific section corresponding to the bar code data (63); and
- (e) playing the specific section (64).
- 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 (20 a) 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. - 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 (20 a) 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).
- 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 theFIG. 1 . - 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 toFIG. 7 , the operation of the flow chart of the preferred embodiment has steps of: - (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);
- (b) receiving the bar code data of the scanning signal (71);
- (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);
- (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;
- (e) obtaining a specific section corresponding to the bar code data (75); and
- (f) playing the specific section (76).
- 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.
- With reference to
FIGS. 9, 10 and 11, the bar code addressing method has steps of: - (a) storing one serial audio signal (80), shown in the wave signal in
FIG. 10 ; - (b) separating the serial audio signal to multiple sections by marking accessing points (AP0-AP3) in the serial audio signal (81);
- (c) storing multiple accessing points (82);
- (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 - (e) listing bar codes on a paper (84), shown in
FIG. 2 . - The bar code generating method has three different types:
- 1. Direct-transforming method. The bar code data is the access point.
- 2. Varied-transforming method. The bar code data is the access point and security data.
- 3. Encryption-transforming method. The bar code data is the encrypted access point.
- 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. - 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.
- 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.
