What is B20 piezo buzzer?

The B20 piezo buzzer is a compact, electronic sound-generating device that uses piezoelectric technology to produce audible tones. Typically powered by direct current (DC), it generates sound through the vibration of a piezoelectric element when an electric current is applied. B20 buzzers are commonly used in various applications, including alarms, notifications, and consumer electronics, due to their low power consumption and versatility. They are favored for their simplicity and ability to generate distinct sounds without the need for complex circuitry.
