Abstract: A microphone includes a separate end cover with a sound port. A diaphragm is directly attached to the end cover. The backplate is positioned within the housing against a ridge near an end of the housing. A spacer is positioned against the backplate. The diaphragm engages the spacer when the end cover, with its attached diaphragm, is installed in the housing. The backplate of the microphone has an integral connecting wire that is made of the same material as the backplate. The integral connecting wire may have an inherent spring force to provide a pressure contact with the accompanying electrical components. The integral connecting wire electrically couples the backplate to the electronic components within the housing and transmits the raw audio signal corresponding to movement of the diaphragm. The housing may have first and second ridges on which the printed circuit board and the electret assembly are mounted, respectively.

Abstract: A microphone and method for dampening the frequency response of the microphone by disposing a dampening frame in a rear volume of the microphone. The microphone generally includes a housing, a diaphragm, a damping frame, and a backplate. The diaphragm rests on embossments in the housing, and a damping frame including a damping slit cut into an inner edge of the damping frame is positioned against the diaphragm. The backplate is positioned adjacent the damping frame to define an aperture which allows air to escape from the area between the backplate and the diaphragm into the rear volume of the microphone, thus dampening the frequency response of the microphone. The method includes the steps of aligning a sheet of diaphragms with a sheet of damping frames, curing these two sheets to form a carrier sheet having a plurality of subassemblies, singulating each subassembly, installing a backplate onto each subassembly to form a cartridge, and placing the cartridge into a microphone housing.
