Piezoelectric buzzer is DC?


A: Piezoelectric buzzer? Black, the common cylinder, is connected to the DC power supply will ring! There are 3V, there are 5V voltage levels. Common in a variety of boards, the computer motherboard generally have one.

If only the piezoelectric ceramic film, it may need DC pulse or AC to sound.


Self-excited piezoelectric buzzer is DC or AC?


A: All called buzzer, of course, is DC. There is already a device that generates luffing current. There are two feet to work. However, some buzzers will also ring in the exchange.

Pin manufacturers vary, generally the middle of the foot is bound, two outside of any. Some two feet is the output of different voices. Just try and you will find out.


If it is a simple piezoelectric ceramic chip, use variable amplitude current. However, the luffing current is not necessarily AC, it can be pulsed DC.


Piezoelectric buzzer resistance?


A: The size of the resistor only represents the voltage range and the rated voltage of the buzzer. There are few resistors in the buzzer, all of which are hundreds of ohms. The quality of the buzzer is judged inferior Listen to the sound, the second look to work; three view material; Piezoelectric buzzer depends on the appearance of the plastic shell mold, the quality of buzz films to determine the quality of the buzzer is the main test buzzer sound.
