Professional manufacturer of SWT buzzer let you know what is a piezoelectric buzzer in a minute?
The electronic buzzer is an integrated structure sounder, divided into piezoelectric buzzer and electromagnetic buzzer two types.
The piezoelectric buzzer is mainly composed of a multi harmonic oscillator, a piezoelectric buzzer, an impedance matching device, a resonance box, a shell, and the like. Some piezoelectric buzzer housing is also provided with a light-emitting diode. The piezoelectric buzzer used by the piezoelectric buzzer is made of lead titanate lead titanate or lead magnesium acid lead piezoelectric ceramic material. The silver electrode is plated on both sides of the ceramic plate, and then is bonded with the brass sheet or the stainless steel sheet after the polarization and the aging treatment. When the piezoelectric material and the metal sheet are applied at both ends of a voltage, because the piezoelectric effect, the buzzer will produce mechanical deformation and sound
