Abstract

PURPOSE:To realize the detection of the transmission signal featuring a high S/N regardless of the noise within car and thus to ensure a high-quality mutual loudspeaker call by using the bone conduction transmitter microphone and the faint field transmitter. CONSTITUTION:When the driver speaks, the vibrations according to the contents of the utterance are transmitted via the bone conduction to the bone conduction transmitter microphone 5 which is pressed by the frame of the glasses, thus obtaining the telephone signal output according to the vibrations. This signal output is modulated by faint field transmitter 6 and then discharged into the car via antenna 7 incorporated into the glasses frame. The modulated output is then received through antenna 8 and transmitted by transmission signal radio receiver 9 to mobile transmitter/ receiver 10 directly or via demodulation to be transmitted to base station 12 through antenna 11. While the electric waves arrived station 12 are demodulated via antenna 11 and transmitter/ receiver 10 and then amplified 13 to be discharged through speaker 14 in the form of the voice. In this case, the sensitivity of microphone 5 is very low to the air vibrations, and accordingly the acoustic combination can be ignored even though the sound volume of speaker 14 may be increased.
