Small Piezo Buzzer
5V / 12V Passive Electrical Piezo Buzzer For Print.
The working principle of the passive buzzer is the same as that of the speaker. When using a square wave signal source to drive, a diode should be connected in reverse parallel to prevent the high-voltage reverse electromotive force generated when the power is suddenly cut off from breaking down other components and shortening the service life.
