ABSTRACT:
An electroacoustic transducer uses a bilaminar vibratile element having at least two plate members which are bonded together in face-to-face relationship, at least one of the plates being made from a piezoelectric material. The bilaminar plate is supported within a frame-like structure by resilient pads which attach the bilaminar plate at its nodal points to the surface of the supporting frame.
