Early devices were based on an electromechanical system identical to an electric bell without the metal gong. Similarly, a relay may be connected to interrupt its own actuating current, causing the contacts to buzz. The word buzzer comes . A buzzer is a mechanical, electromechanical, magnetic, electromagnetic, electro-acoustic or piezoelectric audio signalling device.
A piezo electric buzzer can be driven by an oscillating electronic circuit or other audio signal source.
A click, beep or ring can indicate that a button has been pressed. Black plastic front,vented metal back. Note: Used in paging, warning signals, metal detectors and alarm clocks. Miniature magnetic transducers req. All the parts found here can be ordered at radioshack.
