🔍 What is a Piezo Buzzer?

A piezo buzzer is an electronic sound-producing device that uses a piezoelectric ceramic element to generate audio signals.

When voltage is applied, the piezoelectric material vibrates rapidly, producing sound waves. Piezo buzzers are widely used because they are compact, efficient, durable, and capable of generating loud sounds with low power consumption.

⚡ Working Principle of DC 3-24V Buzzer

The buzzer contains a piezoelectric ceramic disc that changes shape when electrical voltage is applied.

As the disc vibrates rapidly, it creates pressure waves in the air, producing an audible beep sound. Since this model is an active buzzer, it contains an internal oscillation circuit that automatically generates sound when DC power is applied.

This allows users to activate the buzzer simply by supplying the required voltage without needing additional signal generation circuits.
