状振動部を成型した圧電スピーカー。A plastic case that holds the outer periphery of a piezoelectric element, which has a structure in which a thin piezoelectric ceramic plate is bonded to a thin metal diaphragm having a wider area, is formed by insert molding the outer periphery of the piezoelectric element at the same time as the plastic case is molded. This piezoelectric speaker has a thin annular vibrating section molded between the insert molding section and the outer shell of the thick plastic case.
