<P>PROBLEM TO BE SOLVED: To effectively reduce vibration noise to be generated because of the rolling of a microphone unit by a vibration component to be orthogonally crossed with the main axial direction of the microphone. <P>SOLUTION: A dynamic microphone includes: a microphone unit 110; a middle cylinder 120 constituting a microphone body 10 together with the microphone unit 110 and having a rear part air chamber inside; and a microphone case 20. In the dynamic microphone, the middle cylinder 120 of the microphone body 10 is partially supported by a floating system via elastic members 30 inside the microphone case 20. A weight 40 for matching the center of gravity O of the microphone body 10 with a fulcrum S by the elastic members 30 is attached to the middle cylinder 120 so as to be, preferably, movable. <P>COPYRIGHT: (C)2012,JPO&INPIT |
