Abstract
There is provided a surface mount parallelepiped condenser microphone (100). In the surface mount parallelepiped condenser microphone (100), a case (102) has a rectangular box shape with an opening, a backplate (104) has a circular shape with a sound hole, a spacer (106) has thin ring shape, an insulation ring (108) has a hollow cylindrical shape with top and bottom openings, a diaphragm (110) faces the backplate with disposing the spacer therebetween, and a PCB (114) has a rectangular shape with a sound hole at a center portion, the PCB being electrically connected with the diaphragm (110) through a conductive ring (112), wherein a metal ring (103), the backplate (104), the spacer (106), the insulation ring (108), the diaphragm (110), the conductive ring (112), and the PCB (114) are sequentially disposed in the case (102), and the case is curled at the opening.
