An electret capacitor microphone is constituted by a surface conductive diaphragm, a fixed electrode provided opposite to the diaphragm at a regular interval and a solid state device for converting, into an electric signal, a voice given to the diaphragm with a change in an electrostatic capacity between the diaphragm and the fixed electrode. The microphone comprises a dielectric casing having a bottomed hollow portion for accommodating the diaphragm, the fixed electrode and the solid state device. Since the casing itself is dielectric, it does not deed to accommodate a special dielectric or a board for the solid state device but can be directly provided in the hollow portion. Therefore, the microphone can be very small-sized and thinned. The hollow portion of the casing has a stepped portion and the diaphragm or the fixed electrode is fixed onto the stepped portion. The hollow portion of the casing has a rectangular cross section and the external shape of the casing is rectangular, the parts can easily be provided in the hollow portion, an unnecessary space can be omitted, and a size can be reduced.

A disposable-type hearing aid uses a relatively large single diaphragm or a large single diaphragm subdivided into a plurality of smaller active diaphragm areas obtained using a grate-like back support plate with ridges which contact and divide the diaphragm into the several smaller active diaphragm areas. The diaphragm and a backplate are enclosed in a metal housing and are disposed proximal and parallel to a shell-like hearing aid enclosure having sound inlets. The metal housing is closed at an end opposite the sound inlets by a printed circuit board (PCB) forming an acoustical seal for a back volume of the microphone. The PCB also carries substantially all the electronic components for the hearing aid thereon. The PCB has a ground plane in contact with the housing whereby the PCB also acts as an EMI shield. An electrical connection is formed in various ways between the back support plate and the PCB during assembly of the metal housing and components with the PCB. Mass production of disposable hearing aids with large diaphragms and relatively low noise levels is thus possible using this invention.
