Buzzers are sound-emitting devices used to provide audible alerts or feedback in electronic systems. These devices are commonly found in alarms, timers, and notification systems, where they produce a tone, beep, or alarm sound to signal an event or status change. Buzzers are essential for providing audible feedback in applications such as security systems, household appliances, and industrial equipment.

With their ability to produce clear and distinct sounds, buzzers are an important part of any system that requires an audible alert. For engineers designing notification systems, buzzers offer a reliable and effective way to ensure that users are informed of important events or conditions.
