Abstract

PURPOSE:To make a wide-band sound reproducing possible to obtain a desired frequency characteristic, by providing vibrating systems, where cone papers different in diameter are connected, for respective piezo-electric diaphragms different in diameter which are laminated concentrically through flexible substance layers. CONSTITUTION:Plural disc-shaped piezo-electric diaphragms 5, 7, and 9 different in diameter are laminated concentrically through flexible substance layers 11, 12, and 14 according to diameter size. Plural cone papers 6, 8, and 10 different in diameter are connected concentrically to diaphragms 5, 7, and 9. Thus resonance frequencies of diaphragms 5, 7, and 9 are shifted to the lower side successively, and wide-band synthesized reproduced sounds are obtained from cone papers 6, 8, and 10.
