Product Description
Wide Range of Applications
Widely used in computers, printers, smart locks, copiers, alarms, electronic toys, electricity meters, electronic equipment, timers and various DIY electronic products as sound devices.
The piezoelectric buzzer is mainly composed of a multivibrator, a piezoelectric buzzer, an impedance matcher, a resonance box, and a shell.The multivibrator is composed of transistors or integrated circuits. When the power is turned on (1.5~15V DC working voltage), the multivibrator starts to vibrate and outputs 1.5~2.5kHZ audio signals, and the impedance matcher drives the piezoelectric buzzer to sound.The piezoelectric buzzer is made of lead zirconate titanate or lead magnesium niobate piezoelectric ceramic material. Silver electrodes are plated on both sides of the ceramic sheet, and after polarization and aging treatment, they are then glued together with the brass sheet or the stainless steel sheet.
