  • Cylindrical microphone having an electret assembly in the end cover
    Patent number: 7286680
    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.
