Abstract
A system includes a microphone having a diaphragm disposed over an electrode on a substrate, coupled to the substrate by a spring, and having a cap layer with a cavity and a vent hole disposed over the diaphragm, wherein the diaphragm moves and changes capacitance with respect to the electrode in response to sound pressure, a speaker having another diaphragm disposed over another electrode on the substrate, coupled to the substrate by another spring, and having another cap layer with another cavity and another vent hole disposed over the other diaphragm, wherein the other diaphragm moves with respect to the other electrode in response to driving signals applied between the other diaphragm and the other electrode, and a CMOS substrate coupled the substrate, to the speaker and microphone, and configured to process the changes in capacitance and configured to provide the driving signals.
