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.
