Widely used passive buzzer that can emit tone melody sound when powered with wave signal.

Passive buzzer does not have built-in resonator, thus you are required to generate a tone signal for it to emit variable tone sound. Can be used as an on-board mini speaker. Great for very small project that requires variable tone, or even singing melody!

Active buzzer or passive buzzer type can be distinguished by the look of its bottom, active buzzer bottom is filled with epoxy to seal the resonator circuit while passive buzzer bottom is exposed.
