電気音響変換器。 It consists of a diaphragm in which a piezoelectric element with a smaller area than the metal plate is integrally laminated on a metal plate, and a case and a cover that are integrally coupled facing each other. In a piezoelectric electroacoustic transducer comprising a storage case that is clamped and fixed on opposing surfaces of the case and the cover, an engaging protrusion is provided protrudingly on one of the case and the cover, and the engaging protrusion is allowed to enter into the other. A vertical groove portion that allows the case and cover to approach each other relatively, and an engaging protrusion that is connected in the cross direction of the vertical groove portion and enters the vertical groove portion interfere with each other when the case and cover are rotated relative to each other, and cause the case and cover to become closer together. 1. A piezoelectric electroacoustic transducer characterized in that a coupling groove is formed with a lateral groove portion for forced relative approach.
