Piezoelectric buzzer or piezo buzzer
The main components of a piezoelectric buzzer are a type of piezoelectric ceramic element
An electronic pronunciation component is a piezoelectric device placed between two copper circular electrodes
Ceramic dielectric material, when connecting AC audio signals on two electrodes
When the piezoelectric element vibrates according to the magnitude and frequency of the signal, it generates corresponding vibration sound.
The difference between electromagnetic buzzer and piezoelectric buzzer
Piezoelectric buzzer is driven by the piezoelectric effect of piezoelectric ceramics
The vibration of metal sheets causes sound; Electromagnetic buzzer, on the other hand, uses electromagnetic
Principle: When powered on, the metal vibrating film is sucked down, and when not powered on, the vibrating film is used
The elastic rebound of the piezoelectric buzzer is driven by a square wave.
The electromagnetic type is driven by 1/2 square wave, and the piezoelectric buzzer needs to be compared
A high voltage is necessary to have sufficient sound voltage, generally recommended to be above 9V.
Some specifications of piezoelectric can reach over 120dB, with larger sizes
It is also easy to reach 100dB. The electromagnetic buzzer can be used at 1.5V
To emit a sound pressure of over 85dB.
