PURPOSE:To attain miniaturization by providing a speaker for reception and a means converting an infrared-ray signal from a main body unit into a voice signal and sending the signal to the speaker and providing the reception unit removable to the main body unit. CONSTITUTION:A main body 20 and a reception unit 10 are removed freely, and a microphone 26 for transmission, a circuit for radio communication and a means converting the reception signal from the circuit into an infrared-ray signal and sending the signal are provided to the main body unit 20, and a mean converting the infrared ray signal from the transmission speaker 11 and the main body unit 20 into a voice signal and sending to the speaker 11 is provided to the reception unit 10. Thus, the main body unit 20 and the reception unit 10 are separated and they are faced to the mouth and the ear of the user respectively to attain talking and miniaturization. |
