Abstract

An acoustic transducer includes a first flexible structure having a top surface and a bottom surface. A transducer is attached to the top surface of the first flexible structure, wherein the transducer causes deformation of the first flexible structure when an input electrical signal is applied to the transducer. A second flexible structure has a convex top surface and a concave bottom surface. The convex top surface of the second flexible structure is in contact with the bottom surface of the first flexible structure. Deformation of the first flexible structure causes deformation of the second flexible structure.
