The buzzers use the reverse piezoelectric effect to make a piezoelectric plate vibrate and generate sound. The mono-tone buzzer can be used straightforwardly.
Working Principle
The piezoelectric effect refers to the process of producing an electric current when piezoelectric materials are deformed by external force. Conversely, an electric current going through piezoelectric materials causes the materials deformed, which is called reverse piezoelectric effect.
