24v piezo buzzer knowledge

Buzzer from the structure is divided into piezo buzzer and electromagnetic buzzer. Piezoelectric ceramic chip pronunciation, the current is relatively small, electromagnetic buzzer coil vibration power pronunciation, the volume is relatively small.

In accordance with the drive mode is divided into active buzzer and passive buzzer.Active and passive here do not refer to the power source, but the source of oscillation.The active buzzer comes with an internal oscillator, as shown in Figure 9-8, giving the BUZZ pin a low level and the buzzer will ring directly. The passive buzzer internal is not with the source of oscillation, let him ring must be 500Hz ~ 4.5KHz pulse frequency signal to drive it will ring. Active buzzer is often more expensive than passive buzzer, because there are more oscillating circuit, the drive pronunciation is simple, can drive by the level, and the passive buzzer price is cheaper, in addition the passive buzzerSound frequency can be controlled, and the scale and frequency have a definite correspondence, so you can do the effect of "do re mi fa sol la si", you can use it to create a simple music track, such as birthday song
