PURPOSE:To simplify the assembling and to attain small size and light weight, by providing a microphone unit inserting hole to a part of a printed board and incorporating the microphone unit inserted to the hole with an electric circuit by means of an anti-vibration unit. CONSTITUTION:The microphone unit inserting holes 17, 18 are provided to a part of a flexible printed board 13 constituting the microphone circuit. The board 13 and the microphone units 11, 12 inserted to the inserting holes 17, 18 are incorporated with rubber vibrating insulators 14, 15 having a vibration resistance effect. Thus, the physical size is decreased and the miniaturization is attained. |
