发明名称 PIEZOELECTRIC LOUDSPEAKER
摘要 PURPOSE:To reduce a sound distortion, by constituting a loudspeaker so that the center part of a piezoelectric diaphragm installed to a vibrating film is made to stand still pressure through an elastic body. CONSTITUTION:A bending piezoelectric diaphragm 9 is stuck on the center part of a vibrating film 8 which is held and fixed between frames 12, 13. On both sides of the film 8 and the diaphragm 9, elastic bodies 10, 11 are made to adhere. Supporting projections 12a, 13a of the frames 12, 13 hold the center part of the film 8 and the diaphragm 9 between them by pressure through the elastic bodies 10, 11. Accordingly, since they are held between the frames by pressure through the elastic bodies 10, 11, generation of bounce is suppressed.
