PROBLEM TO BE SOLVED: To solve a problem in a conventional microphone where a vibration detection section has holes through which air communicates and the holes are provided in such a way that they communicate from the outer circumference 1 of the vibration detection section to the inside, a force exerted to an output terminal of the vibration detection section deforms deforms the vibration detection section distort a membrane frame to cause a slack or tension to thereby changing a microphone output. SOLUTION: The holes for air are provided indecently of the outer circumferential part of the vibration detection section.
