Applied to washing machines:
The buzzer used in washing machines often emits a beep to prompt users about the operation process.
Applied to gas appliances:
In gas appliances, the buzzer emits an alarm sound to warn users that the gas appliance is burning.
Applied to doorbells:
As a doorbell application, the buzzer emits a "ding dong" sound or music sound to alert guests to visit.
Applied to alarms:
The buzzer installed in public security, banks, and home warning areas often emits alarm sounds. In factories, schools, and application areas, the buzzer often emits electric ringing tones.
◊ According to the different types of buzzers, their working power supply also varies. Some are connected to DC, such as electric horns used in cars; Some are connected to communication, while others need to be connected to specific electronic circuits.
◊ Widely used in computing, printers, repeaters, alarms, electronic toys, automotive electronic devices, telephone timers, etc.
