A piezo buzzer is a small device that converts electrical signals into sound waves. Unlike traditional speakers, piezo buzzers operate on the piezoelectric effect. When a voltage is applied, the buzzer's piezoelectric crystal deforms, producing sound waves. This simplicity makes piezo buzzers cost-effective, lightweight, and ideal for applications where the space is limited.
