  • An electronic circuit of the audio player [0036] 10 and headphone 20 will be described with reference to FIG. 4. The audio player 10 comprises a music file 31 which stores music data read out from a memory card; a digital transmission data generator 32 which generates digital transmission data from the music file 31; and a digital data modulating device 33 which modulates digital data, thereby transmitting the modulated data to the headphone 20 wirelessly. The audio player 10 further comprises a receiving device 34 which receives a retransmission request command delivered from the headphone 20; and a retransmission request interpreter 35 which interprets the retransmission request command received by the receiving device 34, thereby inputting the interpreted command to the digital transmission data generator 32.
  • The headphone [0037] 20 comprises a receiving device 41 which receives data delivered from the audio player 10; an error detecting/correcting circuit 42 which detects and corrects an error of the received signal; a data buffer 43 which stores the error corrected data; and a D/A converting/amplifying circuit 44 which converts and amplifies the digital data stored in the data buffer 43 sequentially into analog signals, thereby driving the speaker 24. The headphone 20 further comprises a retransmission request generator 45 which, in the case where an error cannot be corrected by the error detecting/correcting circuit 42 or in the case where some of the data cannot be received because the electric waves are interrupted, generates a retransmission request; and a digital data modulating device 46 which modulates the generated retransmission request, thereby transmits the request to the audio player 10.
  • In the above configuration, the audio player [0038] 10 generates digital transmission data based on the music file 31 at the digital transmission data generator 32, and modulates the generated data by the digital data modulating device 33, thereby wirelessly transmitting the modulated data to the headphone 20. An error correction code is added to data transmitted from the audio player 10.
  • The headphone [0039] 20 receives music data delivered from the audio player 10 by the receiving device 41, carries out error detection and error correction by the error detecting/correcting circuit 42, and stores the resultant data in the data buffer 43. The data stored in the data buffer 43 are sequentially read out to the D/A amplifying circuit 44, the read out data is converted into an analog signal, and is amplified, thereby driving the speaker 24.
  • In the case where an error cannot be corrected by the error detecting/correcting circuit [0040] 42 or in the case where some of the data cannot be received because the electric waves are interrupted, a command for generating a retransmission request is delivered from the error detecting/correcting circuit 42 to the retransmission request generator 45, and a retransmission request command is outputted from the retransmission request generator 45. The retransmission request command is modulated by the digital data modulating device 46, and the modulated command is delivered to the audio player 10.
  • The audio player [0041] 10 receives a retransmission request command delivered from the headphone 20 by the receiving device 34, interprets the received command by the retransmission request interrupting section 35, and instructs the digital transmission data generator 32 to retransmit data. The digital transmission data generator 32 retransmits data on a portion requested in accordance with the instruction from the retransmission request interpreter 35.
  • As has been described above, according to the first embodiment, the audio player [0042] 10 and headphone 20 are connected to each other via wireless communication, thus eliminating a connection cord, and freeing the user of cord problems. Because of this, the user can jog while listening to music. In the case of storing the audio player 10 and headphone 20 as well, the cord does not interrupt the user.
  • Digital music data is transmitted from the audio player [0043] 10 to the headphone 20, and thus, a high quality sound can be maintained without degrading a sound quality. The error detecting/correcting circuit 42 is provided at the headphone 20, thereby carrying out error detection and error correction. In addition, in the case where an error cannot be corrected by the error detecting/correcting circuit 42 or in the case where part of data cannot be received because electric waves are interrupted, a retransmission request is generated, thereby data on a portion requested from the audio player 10 is retransmitted. Thus, music data can be transferred without interruption or degradation. That is, the data corrected by the error detecting/correcting circuit 42 or retransmitted data is temporarily stored in the data buffer 43, and then, the temporarily stored data is read out sequentially by the D/A converting/amplifying circuit 44. Thus, even in the case data has been retransmitted, the data can be outputted to the speaker 24 without interruption.
  • Digital music data is transmitted wirelessly from the audio player [0044] 10 so that a plurality of people can listen to the same music by using a plurality of headphones 20. For example, in the case where Bluetooth is used as a wireless communication system, a maximum of eight persons can listen to the same music.
  • A wireless connection between the audio player [0045] 10 and the headphone 20 is provided, thereby providing a higher degree of freedom in the design and configuration of the audio player 10 and the headphone 20.
  • Other embodiments of the audio player according to the present invention will be described. The same portions as those of the first embodiment will be indicated in the same reference numerals and their detailed description will be omitted. That is, an external configuration of the audio player and headphone is identical to that of the first embodiment. Embodiments which are different in circuit configuration will be described below. [0046]
  • Second Embodiment [0047]
  • FIG. 5 shows a circuit configuration of an audio player [0048] 10 and a pair of headphones 20 according to the second embodiment of the present invention.
  • The audio player [0049] 10 generates stereo music data produced when L (left) and R (right) channels are mixed at the digital transmission data generator 32 to be outputted to the digital data modulating device 33. The digital data modulating device 33 modulates L and R mixed music data, and transmits the modulated data to an L-side headphone 20 a and an R-side headphone 20 b.
  • The L-side head phone [0050] 20 a comprises a receiving device 51 a, L-side data extracting section 52 a, D/A converting/amplifying circuit 53 a, and L-side speaker 24 a. The L and R mixed music data received by the receiving device 51 a is inputted to the L-side data extracting section 52 a, and only the L-side data is extracted. Then, the L-side data is converted into an analog signal by the D/A converting/amplifying circuit 53 a, and the converted signal is amplified, thereby driving the L-side speaker 24 a.
  • Similarly, the R-side headphone [0051] 20 b comprises a receiving device 51 b, R-side data extracting section 52 b, D/A converting/amplifying circuit 53 b, and R-side speaker 24 b. The L and R mixed music data received by the receiving device 51 b is inputted to the R-side data extracting section 52 b, and only the R-side data is extracted. Then, the R-side data is converted into an analog signal by the D/A converting/amplifying circuit 53 b, and the converted signal is amplified, thereby driving the R-side speaker 24 b.
  • The L-side data extracting section [0052] 52 a and the R-side data extracting section 52 b extract signals of L and R based on a code included in received data or extract the signals of L and R based on a time division system.
  • With the above configuration, the signals of L and R can be reliably separated at the headphones [0053] 20 a and 20 b, and the user can listen to stereo music.
  • Third Embodiment [0054]
  • FIG. 6 shows a circuit configuration of the audio player [0055] 10 and the pair of headphones 20 according to the third embodiment of the present invention.
  • In the third embodiment, at the audio player [0056] 10, an L-R separator 36 is provided following to the digital transmission data generator 32, and signals of L and R are separated from the data outputted from the digital transmission data generator 32. The signal of L separated by the L-R separator 36 is inputted to a digital data modulating device 33a, and the signal of R is inputted to a digital data modulating device 33 b. The digital data modulating devices 33 a and 33 b modulate signals separated by the L-R separator 36, and transmit the separated signals to the L-side headphone 20 a and the R-side headphone 20 b. The digital data modulating devices 33 a and 33 b transmit signals by using a frequency division system, for example.
  • The L-side headphone [0057] 20 a comprises a receiving device 51 a, a D/A converting/amplifying circuit 53 a, and an L-side speaker 24 a. The receiving device 51 a selectively receives an L-side signal transmitted from the digital data modulating device 33 a, and inputs the received signal to the D/A converting/amplifying circuit 53 a. The D/A converting/amplifying circuit 53 a converts the L-side signal received by the receiving device 51 a into an analog signal, and amplifies the converted signal, thereby driving the L-side speaker 24 a.
  • The R-side headphone [0058] 20 b comprises a receiving device 51 b, a D/A converting/amplifying circuit 53 b, and an R-side speaker 24 b. The receiving device 51 b selectively receives an R-side signal transmitted from the digital data modulating device 33 b, and inputs the received signal to the D/A converting/amplifying circuit 53 b. The D/A converting/amplifying circuit 53 b converts an R-side signal received by the receiving device 51 b into an analog signal, and amplifies the converted signal, thereby driving the R-side speaker 24 b.
  • In the third embodiment, the signals of L and R are separated at the audio player [0059] 10, and the separated signals are modulated and transmitted independently by digital data modulating devices 33 a and 33 b, respectively. Therefore, the pair of headphones 20 a and 20 b receives the signals of L and R separated in advance, the signals being transmitted from the audio player 10, and the user can listen to stereo music.
  • Fourth Embodiment [0060]
  • The fourth embodiment of the present invention will be described with reference to FIG. 7. [0061]
  • The fourth embodiment relates to a circuit configuration when the microphone [0062] 28 is stored in the headphone 20 as shown in FIG. 3A and FIG. 3B. As shown in FIG. 7, the microphone section 27 comprises the microphone 28, an A/D converting device 61, and digital data modulating device 62, and is configured so as to turn ON/OFF a power supply of the microphone section 27 by a detection signal from a microphone position detector 63.
  • The microphone position detector [0063] 63 outputs a power OFF signal while the microphone 28 is stored in the headphone 20 as shown in FIG. 3A, and outputs a power ON signal while the microphone 28 is pulled out as shown in FIG. 3B. Therefore, when the microphone 28 is pulled out from the headphone 20, the power ON signal is outputted from the microphone position detector 63, and the microphone section 27 operates. In this state, when a voice is inputted from the microphone 28, the voice signal is converted from an analog into a digital signal by the A/C converting device 61, the converted signal is modulated by the digital data modulating device 62, and the modulated data is transmitted to the audio player 10.
  • In the manner described above, the user's voice data can be transmitted from the headphone [0064] 20 to the audio player 10.
  • Although FIG. 7 describes a case where the digital data modulating device [0065] 62 transmits voice data to the audio player 10, the digital data modulating device 62 is connectable to a device other than the audio player 10 or a device having an I/F of the same electric waves as the audio player 10 such a portable telephone/PHS, a personal computer, a television and the like. Therefore, the headphone 20 can be used in a method described below.
  • For example, when the headphone [0066] 20 is used by being wirelessly connected to the audio player 10, in the case where a portable telephone, PHS, or a home telephone (hereinafter, referred to as a portable telephone) is called, the fact that the portable telephone is called is transmitted by electric waves to the audio player 10 and the headphone 20. The audio player 10 temporarily stops reproduction automatically or reduces the volume, and the headphone 20 outputs from the speaker 24 a sound indicating that the portable telephone is called. At this time, the user pulls out the microphone 28 stored in the headphone 20, thereby starting operation as an earphone microphone of the portable telephone. When the portable telephone detects that the headphone 20 starts operation as an earphone microphone of the portable telephone, the current state goes from a called state to a talk state. When the audio player 10 detects that the headphone 20 starts as operation as an earphone microphone, reproduction is temporarily stopped.
  • Then, after the conversation is over, when the microphone [0067] 28 of the headphone 20 is stored, the headphone 20 restarts operation as a general headphone. When the portable telephone detects that an operation as a headphone is restarted, the telephone cuts out talking. When the audio player 10 detects that an operation as a headphone is restarted, the audio player restarts music reproduction that has been temporarily stopped.
  • As has been described above, talk processing can be carried out for a portable telephone by the microphone [0068] 28 of the headphone 20.
  • Otherwise, for example, while a portable telephone is waiting for a call, when it is detected that the headphone [0069] 20 starts operation as an earphone microphone, the portable telephone can execute processing that vocally recognizes voice data of the microphone 28 delivered from the headphone 20, and dials the counterpart.
  • Fifth Embodiment [0070]
  • The fifth embodiment of the present invention will be described with reference to FIG. 8. [0071]
