<p>A directional condenser microphone having a shape of parallelepiped is disclosed. The condenser microphone comprises a case; a diaphragm member; a thin spacer; a cylindrical insulating ring; a back plate; an annular conductive ring; and a PCB. Here, the diaphragm member, the spacer, the insulating ring, the back plate, the conductive ring, and the PCB are sequentially arranged in the case and then the condenser microphone is integrally assembled by curling an end of the case. The condenser microphones of the present invention provides directivity. Further, because the direction of components can be confirmed during a process of SMD, terminal connections of the component can be easily adjusted each other. Accordingly, this can prevent connection surfaces of connection terminals of a main PCB and connection terminals of the condenser microphone from being deviated, and also decrease a failure of connection that may be resulted from change of connection or direction (polarity) of the connection terminals.</p> |
