DESCRIPTION JPS58157298
[0001]
The present invention relates to a microphone. Although the mechanism of the conventional
microphone is analog, the present invention aims to capture the movement of the diaphragm
digitally. The present invention will be described below with reference to the drawings. FIG. 1
shows the principle and comprises a diaphragm 1, a mirror 2, a half mirror 3, a laser light
emitting device L and a light receiving element P. The reflected light from 1 and 2 reaches P, and
it becomes dark or dark due to interference. In other words, if 1 is displaced, light and dark
changes occur in P for each wavelength of light, so if this is counted, the movement (position) of
1 can be detected. However, since it is necessary to detect the distinction between before and
after the movement of 1, 1 is placed in a magnetic field like a velocity type microphone, and
discrimination is made based on its positive / negative using super power. For this purpose, the
conductor is attached to the surface of 1 in a pattern (by forming a number of parallel lines,
making them external in series, making them in a spider coil form, or placing them in the
magnetic field of radial magnetic lines). As described above, according to the present invention,
since displacement of the diaphragm can be detected digitally accurately, there is an effect of
obtaining a high-output microphone with less distortion.
