Patent ID: 8369544

Claim:
A microphone component comprising: at least one piezoelectric transflexural diaphragm element, a signal interface element comprising conductors, the signal interface element comprising a flexible printed circuit with a stiffness below that of the piezoelectric transflexural diaphragm element, a mechanically protective front surface, wherein the mechanically protective front surface is an elastic metal disc of essentially the same dimensions as the piezoelectric diaphragm element, and a supporting resilient layer disposed between the piezoelectric transflexural element and the elastic metal disc, wherein an electrical and mechanical connection between the signal interface element and the piezoelectric transflexural diaphragm element is made of a material having an negligible electrical resistance with respect to an output resistance of the piezoelectric transflexural diaphragm element, a stiffness below that of the signal interface element, and is able to bond the signal interface element and the piezoelectric transflexural element to each other.
