Passive Piezo buzzer features:

  1. Cost lower than another Active piezo buzzer.

  2. Passive internal is not with the source of the shock, so if we directly use the DC signal is no way to make it make a sound, we have to use a 2K-5K square wave to drive it.

Piezo buzzer appearance is usually the circular structure, which is mainly composed of piezoelectric ceramics, leads and resonance chamber.

    Piezoceramic buzzer in the middle of the piezoelectric ceramic is mainly composed of metal plating, ceramic, glue and metal sheet.

    In fact, if we can from an electrical point of view, the piezoelectric ceramic can be simplified into a voltage source and a series model of the capacitor.
