DESCRIPTION

This buzzer module is passive because it does not have any internal electronics to generate a sound or tone.

External electronics or a microcontroller based device, such as an Arduino, is needed to make the device produce a sound.

Because the device is passive, it acts more like a tiny loudspeaker than a buzzer.
