A CONDENSER MICROPHONE AND METHOD OF MAKING THE SAME

摘要

A condenser microphone and a method for manufacturing the same are provided to improve a conducting characteristic between a case and a PCB(Printed Circuit Board) by attaching the case and the PCB to each other by using an adhesive. A case(102) is formed with a cylindrical structure having an open side. A diaphragm(104) is inserted into the case. A back plate(110) is inserted into the case. A spacer(106) is inserted into the case in order to form a space between the diaphragm and the back plate. An insulating base(108) is inserted into the case in order to insulate the case. A conductive base(112) is inserted into the case in order to conduct the back plate. A PCB(120) includes a plurality of components to process a change of capacitance of the diaphragm and the back plate as an electrical signal. The PCB further includes a connective terminal and a connective pattern. An adhesive(140) is used for sealing and curing the case and the PCB.
