Method for manufacturing a condenser microphone
A method for manufacturing a condenser microphone includes forming a diaphragm module using microelectromechanical system (MEMS) techniques. The diaphragm module includes a diaphragm that is deformable by energy of sound waves, and a diaphragm spacer that extends from one side of the diaphragm and controls a tension of the diaphragm. The method further includes providing a backplate with vent holes, aligning the vent holes of the backplate with a central region of the diaphragm, and connecting the backplate to the diaphragm spacer to construct a transducer unit. The diaphragm spacer, the diaphragm and the backplate cooperate to form an air chamber in fluid communication with an environment external to the condenser microphone. The backplate and the diaphragm cooperate to form a condenser. The method further includes enclosing the transducer unit in a housing that includes a shell and a circuit board to form the condenser microphone.
