MOBILE COMMUNICATION TERMINAL AND A WIRELESS COMMUNICATION DEVICE OF HANDS-FREE WHICH ARE COMMUNICATED WITH EACH OTHER BY INFRARED RAYS

摘要

Purpose: a hands-free mobile communication terminal and a wireless communication device be arranged to enable a mobile communication terminal wirelessly with a wireless communication device connection. Construction: a microcomputer (12) is installed in a mobile communication terminal (10) and is used for and an audio data signal in the outside connection for outputting and inputting. First and second infrared port (14,22) is respectively installed in mobile communication terminal (10) and one hands-free (20), for receiving in infrared ray and transmitting audio data signal. One transmitter (24) and a receiver (25) are installed in (20) the one hands-free voice signals for outputting and inputting. One physical combination (26) for typically including coding and decoding circuit is installed in hands-free (20), is exported at voice signal by transmitter (24) and voice signal is converted to audio data signal for converting audio data signal and be sent to mobile communication terminal (10).
