Piezo Buzzer is an electromechanical component that can be controlled by voltage to control its frequency and volume. When a predetermined voltage is applied, it can produce pulse-like sounds. Its frequency can be adjusted by a control circuit, making it especially suitable for use in alarm systems, computers, and digital electronics.

Piezo Buzzer can be accurately controlled by voltage and volume, making it easier to control sound and more convenient to use. Additionally, it produces pulse-like sounds with persistent and clear voices.

Piezo Buzzer has the advantages of precise frequency and volume control, easier control of sound, and better sound effects. Its smaller size also makes it more convenient than other types of buzzers, and it is commonly used in products such as automotive, communication, household appliances, security equipment, and other products for use in scenarios such as alarms and message notifications.
