Abstract

PURPOSE:To reduce the number of components and to make small and light the microphone, by forming the fixed plate located on the printed board in link shape with the conductor member, locating the support so that the external surrounding can be enclosed for the fixed plate and providing the moving plate so that it closes and opposes to the fixed plate. CONSTITUTION:The fixed pole 32 made of electret, and the support 34 in ring shape made of conductor member providing the diaphragm plate 35 as the moving electrode, are respectively provided on the surface of the printed board 31. Further, the fixed pole 32 is located at the center of the wiring board 31 and the back electrode 33 is closed to the printed board 31. Further, the support 34 is located to the external circumference of the fixed pole 32 so that it surrounds the fixed pole 32, and the diaphragm plate 35 is tensioned at the end opposing to the end in contact with the printed board 31 at the support 34. In this printed board 31, the through-holes 36, 37 are provided at the part providing the electrode 33 and the support 34, the circuit pattern 38 is located at the back of the printed board, and the pattern 38 and the printed board 31 are connected via the through-holes 36, 37.
