Patent ID: 7065224

Claim:
A microphone comprising: a diaphragm; a backplate opposing said diaphragm; a spacer element positioned adjacent said diaphragm; a housing having first, second, and third interacting sound chambers, said first sound chamber being substantially defined by walls of said housing and said diaphragm, said second sound chamber being substantially defined by said diaphragm, said backplate, and said spacer element, said third sound chamber being substantially defined by said backplate and walls of said housing; and at least one aperture having a distal end and a proximate end, said distal end of said aperture being adjacent said second sound chamber and bounded at least partially by said backplate, said proximate end being adjacent said third sound chamber and bounded at least partially by a structure other than said backplate, said aperture connecting said second and third sound chambers and having selected dimensional characteristics for dampening a frequency response curve for said microphone.
