When such an input signal is applied, the piezoceramic vibrates rapidly, resulting in the generation of sound waves. A piezo buzzer operates by passing an alternating voltage through a piezoelectric ceramic material. Piezo buzzers operate by utilizing the reverse piezoelectric effect, which occurs when a material deforms in the presence of an electric charge. When an electric charge is applied to a material, it deforms due to the piezoelectric effect. Special materials that exhibit the piezoelectric effect are used to make piezoelectric components. The piezoelectric component is the key feature that distinguishes this type of buzzer. These lightweight and simple buzzers are inexpensive yet dependable, and they are available in a variety of sizes and frequencies to meet the needs of nearly any application. Piezo buzzers are electric devices that generate tone. A buzzer, also known as a sounder, audio alarm, or audio indicator, is a basic audio device that produces sound in response to an incoming electrical signal. The buzzer is the most commonly used device for this purpose.
These audio signals can be produced by a variety of devices. From home appliances and security devices to automotive electronics and office automation devices, audio signals are essential for communicating information from a product to its end user.
