Abstract

PURPOSE:To attain the reproduction of natural sound and common use of transmission and reception, by picking up high frequency sound of bone conduction and low frequency sound of eardrum oscillation at the same time. CONSTITUTION:A space formed with a main body case 11 and a diaphragm 14 is formed as air-tightness, and an acoustic pipe 23 is fitted. In using the microphone, an outer skin contact chip 16 contacts the surface of a living body and an ear chip 24 is inserted an ear hole. The oscillation of the surface of the living body is delivered to the diaphragm 14 via the chip 16. In this case, since the mechanical impedance of the system including the diaphragm 14 is selected to be matched with the synthetic impedance of the living body, the low frequencies are subject to high attenuation rather than the high frequencies. Further, the bone conduction sound includes much high frequency compoents. The sound of the eardrum having low frequency components passes through the pipe 23 and reaches the diaphragm 14. Thus, the oscillation of high and low frequencies is delivered to the diaphragm 14. In case using the microphone as a transmitter, a moving coil 17 oscillates the diaphragm 14 with electric signals and the sound is delivered to the pipe 23 and the eardrum. Further, it is delivered to the surface of the living body via the chip 16.
