Retrieving the storage means of the communication module when a call is received from the caller when the headphones are performing music playback functions, including associated storage means To identify the caller's identification information. It is a headphone which acquires and notifies the acquired identification information via the automatic voice response device.

  Thus, the user can know that a call has been received from a third party even when the headphones with communication function are executing the music playback function. In addition, since the first operation unit and the second operation unit are functionally independent, high operability can be secured even when the music playback function and the communication function are switched and used. Is possible.

  In response to the operation of the second operation unit, the headphone interrupts the music playback function and establishes a call connection with the caller via the communication module.

  The headphones execute the music playback function and the communication function in parallel in response to the operation of the second operation unit.

  Thereby, the user can view and use the music reproduced by the music reproducing function during the call.

  FIG. 1 is a diagram showing an appearance of a headphone 100 of the present invention. A first operation unit 110 and a second operation unit 120 are disposed on the right speaker portion and the left speaker portion 160, respectively. The wireless communication module 130 is inserted into the wireless communication module insertion unit 150 disposed on the side where the operation unit 120 is located between the two speaker portions. On the side where the second operation unit 120 is provided, a microphone unit 170 is provided for calling and giving instructions by the user's voice.

  The first operation unit 110 is used as an interface for viewing music. The first operation unit 110 receives FM radio broadcasts, downloads data from a server, receives music data using Bluetooth technology, and music from a personal computer or the like via a USB terminal disposed in the headphones 100. Used to select a music data acquisition method such as reception of file data. The first operation unit 110 is further used to select music such as which content of the acquired music data is to be played.

  When receiving the FM broadcast, the user selects the FM radio broadcast reception using the first operation unit 110, and tunes the tuning amplification circuit for receiving the FM broadcast to a desired frequency. In the case of downloading from the server, the user designates the URL of the server using the first operation unit 110 and designates the Web component to be downloaded. When using the Bluetooth technology, the user uses the first operation unit 110 to request a Bluetooth connection from the headphone 100 to a terminal such as a server-side personal computer that functions as a modem. When music file data is received from a personal computer or the like via the USB terminal, the user designates a file name stored in the personal computer. Since the headphones of the present invention do not include a display, the above operation is performed according to a voice guide generated from the automatic voice response device. The first operation unit has a function equivalent to that of a conventional music playback portable information terminal.

  The second operation unit 120 is used as an interface related to a communication function such as telephone or e-mail communication. The second operation unit executes functions such as outgoing call, end of call, and telephone directory selection. The user inputs the destination address, telephone number, etc. by voice according to the voice guide from the automatic voice response device. The first operation unit 110 and the second operation unit 120 are functionally completely independent. Thereby, when an incoming call is received while listening to music, a call can be made by operating the second operation unit 120. An incoming call notification during music playback is performed using the background sound. Conversely, when the call is finished, music can be viewed by operating the first operation unit 110. All telephone numbers and the like are announced by voice from the automatic voice response device. The wireless communication module 130 stores an address table. When there is an incoming call while listening to music, the address table of the wireless communication module 130 is searched and the name corresponding to the corresponding address is announced.

  FIG. 2 is a functional block diagram showing a state in which the wireless communication module 130 is inserted into the main body 140 of the headphones.

  The headphone body 140 includes a control unit 210, a PCM codec 220, a speaker 230, a microphone 240, an LED 250, a flash memory 260, a RAM 270, a battery 280, a first operation unit 110, and a second operation unit. It comprises an operation unit 120 and an interface 290.

  The wireless communication module 130 includes a control unit 300, antenna means 310, antenna switch 320, transmission unit 330, reception unit 340, modulation unit 350, demodulation unit 360, multiple access encoding unit 370, multiple It comprises a connection decoding unit 380, an ADPCM (adaptive differential pulse code modulation) transcoder 390, a flash memory 400, a random access memory (RAM) 410, and a power supply 420.

The headphone main body 140 and the wireless communication module 130 are connected via an interface 290. The interface 290 includes 18 pins (signal lines). Seven of these pins, as a UART (Universal Asynchronous Receiver Transmitter) serial interface, are used to transmit control data and data during data communication.Transmit serial data (TXD), receive serial data (RXD), and transmit data Used for ready (RTS), transmit ready (CTS), receive ready (DTR), data carrier detect (DCD), ring indicator (RI). The other four pins are used to exchange audio signals such as PCM clock signal (PCMCLK), PCM synchronization signal (PCMSYNC), PCM input signal (PCMIN), and PCM output signal (PCMOUT). The The other one pin is used to recognize the insertion of the wireless communication module using the detection signal (INS). The other three pins are used for power supply ( _Vcc ) and ground (GND) signals for power supply and ground to the wireless communication module. The remaining three pins are used to display the field strength (antenna display) on the external display device such as LCD and LED of the communication terminal body 110 to send and receive each signal for the field strength. Signal (IF_SEL) is used for checking whether the pin currently used in UART can be used in another data transfer method other than UART, whether it is UART or another method.

  For example, a radio signal representing audio data of music downloaded from a service provider server is received by the antenna unit 310 and sent to the receiving unit 340 via the antenna transmission / reception switching unit 320. The received signal is amplified and bandpass filtered by the receiving unit 340, and demodulated into a baseband signal by performing detection processing in the demodulating unit 360. Thereafter, the decoding unit 380 decodes the ADPCM audio signal. The ADPCM audio signal is sent to the ADPCM transcoder 390 and converted into a PCM audio signal. The converted PCM audio signal is sent to the PCM codec 220 via four pins for exchanging audio signals such as PCMCLK, PCMSYNC, PCMIN, and PCMOUT of the interface 290. The PCM audio signal sent to the PCM codec 220 of the headphone main body 140 is converted into an analog signal and output through the speaker 230. The user can listen to the output audio signal.

  The flash memory 400 has an address table in which a telephone number or address of a call destination is stored. The user operates the second operation unit 120 to stop the music playback while viewing the music, and operates the first operation unit 110 to call the call destination stored in the flash memory 400. can do. In this case, the call destination is also selected according to a voice guide generated by the automatic voice response device, and the user can select an index associated with the address or telephone number of the call destination via the microphone 240, for example. The call destination is selected by inputting a number as.

  When the call connection with the callee is established, the user starts a conversation with the called party via the microphone 240. The user's voice data input via the microphone 240 is sent to the PCM codec 220, subjected to pulse code modulation (PCM), sampled, and converted into a digital signal. The audio signal subjected to pulse code modulation is transmitted to the wireless communication module 130 via the interface unit 290.

  The audio data emitted by the user is sent to the ADPCM transcoder 390 via four pins for exchanging audio signals such as PCMCLK, PCMSYNC, PCMIN, and PCMOUT of the interface unit 290. ADPCM transcoder 390 converts pulse-encoded data into ADPCM-modulated audio data. ADPCM is a waveform coding method similar to PCM, but in order to reduce the number of quantization bits, the next sampling data is predicted from past sampling data, and error data from the actual sampling data is sent. Based on. A technique for reducing the amount of data to be transmitted by predicting the next data from past data and transmitting only the prediction error can be used for encoding an image signal.

    Error data from the audio data of ADPCM transcoder 290 is sent to multiple access encoding section 370. Also, the image data compressed and encoded by the control unit 300 is also sent to the multiple access encoding unit 370. The data encoded by the multiple access encoding unit 370 is modulated by a modulation unit 350 by a known modulation method, and wirelessly transmitted to the base station via the transmission unit 330, the antenna transmission / reception switching unit 320, and the antenna unit 310. .

  The communication between the headphones 100 and the base station may be performed via a network conforming to the third generation (3G) standard, and HSDPA (High Speed Downlink conforming to the 3.5G (so-called beyond3G) standard). Packet Access) may be performed via a network.

  Furthermore, the headphone 100 of the present invention provides a function for checking whether or not the wireless communication module 130 is inserted into the main body 140 of the headphone. Specifically, one of the 18 pins of the interface unit 290 “INS” is used as a signal line for insertion / removal confirmation. The voltage on the signal line when the wireless communication module 130 is not inserted into the headphone main body 140 and the voltage on the signal line when the wireless communication module 130 is inserted into the headphone main body 140 are different from each other. Thus, the main body control unit 210 can detect the current insertion / removal state. Based on the detection result, the main body control unit 210 makes an announcement regarding the insertion / removal state by voice and informs the user whether or not the wireless communication module is inserted. Whether or not the wireless communication module 130 is completely inserted into the main body 140 of the headphones cannot be visually recognized from the outside. Thereby, even if the wireless communication module 130 is not inserted, the user immediately notices the absence of the wireless communication module 130.

  Fig. 3 shows how signals are exchanged between the base station, headphones 100, and the caller when a call is made from the caller while the user is playing music with headphones 100. It is a figure which shows a flow. The user operates the first operation unit 110 to select sound source data (step 510). When the audio data is downloaded from the audio database of the server via the wireless communication module 130, the user operates the first operation unit 110 to give an instruction to reproduce the audio data (step 520). Receiving the instruction, the main body control unit 210 controls the speaker 230 to reproduce the audio data (step 530). At this time, when a third party makes a call to the headphones 100 using the simultaneous call service (steps 540 and 550), the base station notifies the audio player 100 of the incoming call (560). The control unit 300 of the communication module 130 searches the address table in the flash memory 400, acquires the name corresponding to the telephone number of the caller, and sends the acquired name to the main body control unit 210 via the interface 290. . When the main body control unit 210 receives the incoming call notification, the main body control unit 210 controls the speaker 230 to make a voice announcement based on the background sound (step 570). The user operates the second operation unit 120 (step 580) and issues a response instruction to the main body control unit 210 (step 590). Upon receiving the response instruction, the main body control unit 210 sends a response support to the control unit 300 of the wireless communication module 130, and the wireless communication module 130 establishes a call connection with the caller via the base station. (Step 600).

  According to the headphones of the present invention, the user can know that a call has been received from a third party even when the music playback function is being executed. In addition, since the first operation unit and the second operation unit are functionally independent, there is no cost and high operation even when switching between music playback function and communication function. It is possible to ensure the sex. Therefore, it can be used even by a visually impaired person. Furthermore, in response to the operation of the second operation unit, the music playback function and the communication function are executed in parallel, so the user must use the music being played back by the music function during a call as BGM. Is possible.
