音体に電気的に接触したことを特徴とする圧電ブザー。A sounding body made of a small-diameter piezoelectric element attached to the center of the main surface of a diaphragm is housed in a case equipped with an annular protrusion that supports the sounding body on the nodal circle, and an electric current is applied to the sounding body. A terminal is attached to a case lid, and the contact piece is a coiled member made of an ultra-thin metal wire, one end of which is engaged with the terminal and the other end of which is connected to the sounding body. A piezoelectric buzzer that is characterized by the fact that it comes into contact with the object.
