ている。Description of Examples Examples of the present invention will be described below. Second
The figure shows one embodiment of the microphone of the present invention, and in FIG. 2, 11 and 12 are unidirectional microphone units, and 13 is a unit that processes output signals from the unidirectional microphone units 11 and 12. A flexible printed circuit board 14 and 15 constitutes an electric circuit; reference numerals 14 and 15 denote vibration-proofing rubber having a vibration-proofing effect for integrating the unidirectional microphone units 11 and 12 with the printed circuit board 13;
A microphone case 6 houses the unidirectional microphone units 11, 12 and the printed circuit board 13, which are integrated with the vibration-proof rubbers 14, 15. As shown in FIG. 5, the printed circuit board 13 is in the form of a flexible thin sheet, and has insertion holes 17 and 18 for mounting the microphone units 11 and 12, and has a chip on its surface. It has an electric circuit composed of circuit elements 19 such as capacitors, chip resistors, and chip semiconductors. Further, the vibration isolating rubbers 14 and 15 are ring-shaped as shown in FIG. The unidirectional microphone units 11 and 12 are inserted into insertion holes 17 and 18 provided in the printed circuit board 13, and are electrically connected to an input end (not shown) of an electric circuit configured on the printed circuit board 13. Then, by fitting the vibration isolating rubbers 14 and 15 onto the bent printed circuit board 13 while the printed circuit board 13 is bent so as to surround the outer periphery of the unidirectional microphone units 11 and 12. The vibrating rubbers 14 and 15 are also integrated with the printed circuit board 13 by their own elasticity.
Then, the unidirectional microphone units 11, 12 and the printed circuit board 13, which are integrated with the vibration isolating rubbers 14, 15, are housed in a case 16 divided into two parts, and both ends of the case 16 divided into two parts are fixed with screws, etc. By fixing with the above means, the vibration isolating rubbers 14 and 15 are pressed down by the microphone case 16, so that the unidirectional microphone units 11 and 12 exhibit a vibration proofing effect. In addition, the above-mentioned unidirectional microphone unit 1
1 and 12 are mounted at a predetermined distance defined by insertion holes 17 and 18 provided in the printed circuit board 13 so that the directivity axis faces the front direction, thereby forming a secondary sound pressure gradient type microphone. It consists of
