DC 3-24V 85dB Active Buzzer is an electronic component that emits sound when powered by a DC voltage supply within the specified range of 3V to 24V. It is called an "active" buzzer because it has an internal oscillator that generates the sound on its own, unlike a passive buzzer that requires an external oscillator or signal to produce sound.
