<p><P>PROBLEM TO BE SOLVED: To obtain a capacitor microphone unit which heightens the drive capability of a diaphragm in a bidirectional component and also can effectively prevent the occurrence of natural vibration. <P>SOLUTION: A capacitor microphone unit 1 comprises: a diaphragm 2; a diaphragm ring 5 which holds the diaphragm in place with prescribed tension; a fixing pole 3, disposed on the diaphragm 2 facing it via a space, which constitutes a capacitor between itself and the diaphragm 2; a unit case 10 which accommodates the diaphragm ring 5, the diaphragm 2 and the fixing pole 3; and a baffle 101 which is formed in shape of a collar in the outer periphery of the unit case 10. The baffle 101 is provided with an electrostatic flock 103 which prevents the reflection of sounds at least on corners at which planes intersect and around the corners. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
