The piezo buzzer works on the principle of the piezoelectric effect and produces sound based on the reverse of the piezoelectric effect. the electric potentials difference across piezo material is a reason to generate pressure variations. Piezo buzzer is most famous among other types of buzzers because of the higher sound generation using less current. Other names of buzzers are an audio alarm beepers audio indicator audio transducer audible alarm.
