Claims

[Scope of claims for utility model registration] 1. A piezoelectric diaphragm made of a metal plate and a ceramic piezoelectric plate,
A printed circuit board with printed wiring on one side is placed in the recesses of a frame made of synthetic resin and has recesses formed on both sides, with the pattern side of the ceramic piezoelectric plate and the printed circuit board facing inside. Two conductive lead pieces are attached to the frame, one lead piece connects the metal plate to the pattern part of the printed circuit board, and the other lead piece connects to a conductive rubber piece provided in contact with the ceramic piezoelectric plate. A piezoelectric transducer characterized in that the piezoelectric transducer is provided so as to be electrically conductive with the pattern portions of the printed circuit board, a circuit element is mounted on the pattern side of the printed circuit board, and a front cover is attached. 2. The piezoelectric transducer according to claim 1, which is a utility model registration, in which a piezoelectric diaphragm, a frame, and a printed circuit board are stacked and fixed by a front cover.
