    Abstract: Provided are an actuator, method for manufacturing the actuator, and acoustic transmitter having the actuator. The actuator includes: an elastic metal member having a plurality of curved segments and a plurality of connection segments which constitute a ring structure with a long-axis direction and a short-axis direction; a multilayer piezoelectric member disposed within the ring structure and having a plurality of stacked piezoelectric units along the long-axis direction; and a plurality of coupling members disposed within the ring structure, wherein the multilayer piezoelectric member has two ends in the long-axis direction that are coupled to the connection segments of the elastic metal member in the long-axis direction. A preload stress is imparted to the elastic metal member. A plurality of coupling members having a size corresponding to the preload stress are disposed between the elastic metal member and the multilayer piezoelectric member.

    Abstract: A piezoelectric electroacoustic transducer is disclosed. The piezoelectric electroacoustic transducer includes a diaphragm, a piezoelectric element disposed on the diaphragm, an elastic element connected with and around the diaphragm, a frame around the elastic element and being disassembled so as to adjust an inner-frame projected area of the frame, and a buffer interposed between the elastic element and the frame, wherein the frame has an inner-frame projected area less than a planar projected area of the diaphragm, the elastic element, and the buffer, such that the frame always provides a compressive stress to the diaphragm, the piezoelectric element, the elastic element, and the buffer. The piezoelectric electroacoustic transducer may be implemented as a loudspeaker or a microphone.
