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.
