Apr 10, 2023 · Piezo buzzers are compact electronic devices used to produce audible alerts or notifications. They operate based on the piezoelectric effect, a property that allows certain materials to generate an electric charge under mechanical stress.

Simple, compact, and reliable, piezoelectric audible sound transducers —also called tone generators, or buzzers—can deliver a high sound output from a small (milliwatt) energy input. Emitted sounds range from soft hums to strident alarms.

One of the most common choices for audio communication is a buzzer. Understanding some of the technologies and configurations of buzzers is useful during the design process, so in this blog post we will describe typical configurations, provide example buzzer tones, and present common drive circuit options.

While choosing the ideal buzzer for your project, consider the product size, terminal type, sound output, voltage among other factors. Here, we offer buzzers at sound levels from 80 dB to 105 dB. Passive buzzers are used in home appliances, game shows, and other events.
