PURPOSE:To stabilize photovoice conversion by reflecting laser light by a diaphragm arranged in parallel with output plane of a semiconductor laser controlled to a prescribed temperature, feeding back the light positively to an active substance in the laser and photoelectric-converting the output change caused by interference. CONSTITUTION:The laser light is reflected in rsponse to acoustic vibration on a diaphragm 21 arranged in parallel with the output plane of the semiconductor laser 22. The reflected laser light is fed back positively to the active substance of the laser 22, the output causing a change by interference is led to an optical fiber 19, photoelectric-converted and amplified by a circuit (not shown), and outputted as a voice current through a band pass filter. On the other hand, a temperature sensor 17 is provided near the semiconductor laser 22 and the temperature is kept constant by changing the direction of current of a Peltier element 18 foward and reverse so as to heat or cool the laser 22. Further, a corrugated heat sink 20 is formed. Then, the mode jumping of the semiconductor element due to temperature change is prevented for stabilizing the output.

A microphone comprises a substrate (20), a microphone membrane (10) defining an acoustic input surface and a backplate (11) supported with respect to the membrane with a fixed spacing between the backplate (11) and the membrane (10). A microphone periphery area comprises parallel corrugations (24) in the membrane (10) and backplate (11). By using the same corrugated suspension for both the membrane and the backplate, the sensitivity to body noise is optimally suppressed.
