Abstract
A microphone includes a diaphragm assembly supported by a substrate. The diaphragm assembly includes at least one carrier, a diaphragm, and at least one spring coupling the diaphragm to the at least one carrier such that the diaphragm is spaced from the at least one carrier. An insulator (or separate insulators) between the substrate and the at least one carrier electrically isolates the diaphragm and the substrate.
Claims22
A microphone comprising:
- a substrate;
- a diaphragm assembly supported by the substrate, the diaphragm assembly including at least one carrier, a diaphragm, and at least one spring coupling the diaphragm to the at least one carrier, the diaphragm being spaced from the at least one carrier;
- and
- at least one insulator between the substrate and the at least one carrier so as to electrically isolate the diaphragm and the substrate.
1 more element
A microphone comprising:
- a substrate;
- a diaphragm;
- support means for movably coupling the diaphragm to the substrate, the support means including carrier means for fixed coupling with the substrate and suspension means for movably coupling the diaphragm to the carrier means and spacing the diaphragm from the carrier means;
- and
- insulator means for electrically isolating the diaphragm and the substrate.
