Description
This is a commonly used passive buzzer module, it mainly uses 12*8.5MM 5V 2K without source buzzer component. There is no oscillating circuit inside the passive buzzer component. When controlling, the GND VCC on the block is powered, the signal terminal S inputs square waves of different frequencies (voltage 5V), and controls the buzzer sounds different frequencies. The center frequency of this component is 2KHz. Passive bee There is a one-to-one correspondence between the driving frequency and the occurrence frequency of the buzzer, that is, the driving frequency is 2KHz square wave, the frequency of the sound heard is also 2KHz.
The other is the spacing the 2.54mm pin header interface can be directly connected to the single-chip microcomputer using male-to-female DuPont cable.
