音器。In a piezoelectric alarm device that generates sound by bending a piezoelectric vibrator, a piezoelectric element is bonded to the outer bottom of a cylindrical diaphragm with one end open to form a piezoelectric vibrator, and the piezoelectric vibrator is used as a sound wave reflector. The opening of the diaphragm is placed in front of the
A piezoelectric type characterized in that a cylindrical case having a sound emitting port on the front is connected to the outer edge of a sound wave reflector so as to surround the cylindrical part of the diaphragm, and a sound path is formed between the cylindrical diaphragm and the cylindrical diaphragm. Alarm bell.
