摘要： PURPOSE:To improve low frequency characteristic by forming alternately a slot deviated from both faces of an adhered member with a piezoelectric member adhered thereto at the border between a free state part displaced as a diaphragm and a stationary part supporting the diaphragm. CONSTITUTION:A piezoelectric substance 12 formed with an electrode 11 on its both sides is adhered to the center of a metallic disk 13 and the circumference part is fixed by a stationary part 14 in the diaphragm. Plural slots 15 are formed alternately while their positions are deviated to the both sides from the part close to the inner circumferential part of the stationary part 14 between the outer peripheral part of the piezoelectric member on the metallic plate 13 and the inner peripheral part of the stationary part 14. The slots at the peripheral stationary part facilitate the flexure deformation caused in the application of an electric field to the piezoelectric member and the diaphragm is moved freely by utilizing the slots. Thus, the movement of the diaphragm due to the stationary body 14 is not hindered and the resonance frequency is far lowered.
