ー。 The outer periphery of a piezoelectric vibrator made by bonding a piezoelectric element and a diaphragm together is housed in a case that has acoustic effects, etc., a printed circuit board is fixed inside the back cover fixed to the case, and a plurality of devices are mounted on the printed circuit board. In a piezoelectric buzzer in which the tip of a spring terminal is brought into contact with a plurality of electrodes of the piezoelectric vibrator, the base of the spring terminal is brought into close contact with the upper surface of the printed circuit board, and the cut provided in the base is bent downward. The cut-and-raised portion formed by the above-mentioned method is inserted into the insertion hole of the printed circuit board, the tip thereof is bent onto the back surface of the printed circuit board, and the printed circuit board is fixed by caulking so that the printed circuit board is sandwiched between the base portion and the cut-and-raised portion. Piezoelectric buzzer.
