After decoded, the MP3 digital file becomes a voice signal and is outputted to the earphone 20 so that the user can hear the voice content of the MP3 digital file via the earphone 20. Furthermore, the display unit 17 can also display the related message of the MP3 digital file so as to make the user realize the content of the displayed MP3 digital file.

Please refer to FIGS. 1 and 2 again. The voice signal transmission and encoding/decoding unit 12 connects with the DSP unit 10, Bluetooth module 14, earphone 20 and microphone 22. The voice signal transmission and encoding/decoding unit 12 is used for encoding/decoding voice and converting digital/analog messages. It can decode the message signal 301 received by the Bluetooth module 14 and display a incoming phone number via the display unit 17 after employing the DSP unit 10 to process the message signal 301. It can also encode the message processed by the DSP unit 10 and send the reply modulation signal 302 to the Bluetooth cellular phone 30 via the Bluetooth module 14.

When getting a phone call, the Bluetooth module 14 will receive the message signal 301 and then pass it to the voice signal transmission and encoding/decoding unit 12 for decoding. Subsequently, after processed by the DSP unit 10, the message signal 301, which is an incoming phone number, will be shown on the display unit 17. Accordingly, a user can recognize the identity of the other side and decide if it is necessary to answer the phone.

At this time, if the user chooses to answer the phone, the incoming voice signal can be heard by the user clearly via the earphone 20 after processed by the DSP unit 10. Further, if the user is listening to a voice message of a MP3 music file via the earphone 20 at this time, the DSP unit 10 will interrupt the playing of the MP3 file in advance and then the user can hear the telephone voice message via the earphone 20. When the phone is hung up, the DSP 10 will recover the playing of the MP3 file.

Meanwhile, when the user speaks, the voice message will be sent via the microphone 22 to the voice signal transmission and encoding/decoding unit 12. After processed by the voice signal transmission and encoding/decoding unit 12, the voice message will be passed to the Bluetooth module 14. Then, the Bluetooth module 14 will send a corresponding reply modulation signal 302 to the remote Bluetooth cellular phone 14 (see FIG. 1). By this way, the full-duplex voice communication can be obtained.
