- 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 indicator, computers, call bells etc.
- Piezo buzzer is based on the inverse principle of piezoelectricity discovered in 1880 by Jacques and Pierre Curie.
- It is the phenomena of generating electricity when mechanical pressure is applied to certain materials and the vice versa is also true.
- Such materials are called piezoelectric materials.
Description
- 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 indicator, computers, call bells etc.
- Piezo buzzer is based on the inverse principle of piezoelectricity discovered in 1880 by Jacques and Pierre Curie.
- It is the phenomena of generating electricity when mechanical pressure is applied to certain materials and the vice versa is also true.
- Such materials are called piezoelectric materials.
- Piezoelectric materials are either naturally available or manmade.
- Piezoceramic is class of manmade material, which poses piezoelectric effect and is widely used to make a disc, the heart of 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 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.
