Electret capacitor microphone |
摘要 |
An electret capacitor microphone includes an electret capacitor section having a diaphragm and a backplate, an impedance conversion element for converting a change in the electrostatic capacity of the electret capacitor section into an electric impedance, and a case for accommodating the electret capacitor section and the impedance conversion element. Part of the case is a synthetic resin-made base member formed integrally with a plurality of terminal members by insert molding. One end of the terminal member is exposed on an inner surface of the base member so as to form part of a conductive pattern. The other end of the terminal member is exposed on an outer surface of the base member as an external connection terminal portion. The impedance conversion element is mounted on the base member at a predetermined position in the conductive pattern.
