Buzzer (Big)
Use this economical piezo-electric buzzer in experiments that require a doorbell or buzzer. This electric buzzer works off 3-24 volts. We recommend our 6-volt or 9-volt battery.
A Piezo buzzer is an electronic device commonly used to produce sound. Lightweight, simple construction and low price make it usable in various applications like car/truck reversing indicators, computers, call bells, etc. It is the phenomenon of generating electricity when mechanical pressure is applied to certain materials and vice versa is also true. Such materials are called piezoelectric materials. Piezoelectric materials are either naturally available or manmade.
Piezoceramic is a class of manmade material, which poses a piezoelectric effect and is widely used to make a disc, the heart of a piezo buzzer. When subjected to an alternating electric field they stretch or compress, in accordance with the frequency of the signal thereby producing sound. The piezo buzzer produces sound based on the reverse of the piezoelectric effect. The generation of pressure variation or strain by the application of an electric potential across a piezoelectric material is the underlying principle. These buzzers can be used to alert a user of an event corresponding to a switching action, counter signal, or sensor input. They are also used in alarm circuits.
