摘要： A piezoelectric speaker includes: a chassis having a wall surface including an opening; a plurality of diaphragms including at least a first piezoelectric diaphragm and second piezoelectric diaphragms which vibrate in phases opposite to each other when a voltage is applied; and a joint member which connects the first and second piezoelectric diaphragms in a positional relationship such that the diaphragms are located at positions different from each other in a thickness direction. One of the diaphragms is provided, in the opening of the chassis, to have one surface facing an outside of the chassis and another surface facing an inside of the chassis. The diaphragm functions as a radiation plate which radiates a sound wave by vibrating at an amplitude generated by synthesizing amplitudes of the first and second piezoelectric diaphragms.

摘要： A piezoelectric acoustic transducer (1) of the present invention includes a lower frame (78), a lower speaker circuit (20), an upper frame (77), an upper speaker circuit (10), and a surround (76). The upper speaker circuit (10) has a piezoelectric diaphragm (14) in which piezoelectric elements (16, 17), each having a structure that flat plate electrodes are disposed on top and bottom of a piezoelectric member, are mounted on top and bottom surfaces of a board (15). The lower speaker circuit (20) has a piezoelectric diaphragm (24) in which piezoelectric elements (26, 27), each having the same structure, are mounted on a top surface and a bottom surface of a board (25). The piezoelectric diaphragms (14, 24) are coupled to each other via coupling members (74, 75). At an application of a voltage, the piezoelectric diaphragms (14, 24) are caused to curve in directions opposite to each other. Having this structure, the piezoelectric acoustic transducer (1) has an increased displacement in a thickness direction thereof, and thereby achieving high quality sound with space-saving.
