Patent ID: 8631711

Claim:
A MEMS composite transducer comprising: a substrate, portions of the substrate defining an outer boundary of a cavity; a MEMS transducing member, a first portion of the MEMS transducing member being anchored to the substrate, a second portion of the MEMS transducing member extending over at least a portion of the cavity, the second portion of the MEMS transducing member being free to move relative to the cavity; and a compliant membrane positioned in contact with the MEMS transducing member, a first portion of the compliant membrane covering the MEMS transducing member, a second portion of the compliant membrane being anchored to the substrate, and a third portion of the compliant membrane overhanging the cavity while not contacting the MEMS transducing member, the MEMS transducing member comprising a beam having a first end and a second end, wherein the first end and the second end are each anchored to the substrate.
