Title: Microphone device
Inventor: HORIKOSHI TATSUO
IPC: H04R3/00
Filed: 1982-07-17
Abstract: PURPOSE:To eliminate completely the additional mass to a diaphragm and to improve both transient characteristics as well as sensistivity for a microphone device, by irradiating the laser light to the diaphragm and making use of the interference between the reflected light of the laser light and the reference light to read digitally the displacement of the diaphragm. CONSTITUTION:Half of the laser light irradiated from a laser source 1 transmits as it is through a half mirror 3 and goes toward a diaphragm 5 to be totally reflected. The reflected light has the mutual interference at the front of slits 8a and 8b in response to the difference between optical path lengths L1 and L2 and produces interference fringes 7. The fringes 7 have periodical changes every time the difference between L1 and L2 changes by a wavelength lambda and then have a change of a period when the diaphragm 5 has a lambda/2 displacement. A shift of the fringes 7 due to the displacement of the diaphragm 5 is detected by photodetectors 9a and 9b having a prescribed phase relation. These detected signals 9a' and 9b' are turned into digital signals 9a'' and 9b'' which contain digital information 6. These digital signals are transmitted through a transmission line. Such digital signals have reduced effects due to the noises of the transmission line and a small loss. Thus it is possible to transmit the audio information with high fidelity.
