The reversing buzzer is used on vehicles to make a sound when the vehicle is backing up. It is used to remind pedestrians or other vehicles to be careful. This vehicle is backing up, and it can indirectly make a sound. So how does the reversing buzzer work and what is its working principle? Next, let's introduce Wujin Yueda's electric reversing buzzer to everyone.

The traditional reversing beeurine is mainly composed of coils, contacts, capacitors and bee twisters. It is actually controlled by a relay circuit. There are two sets of coil L1 and L2, and the coil L2 circuit is connected in series with the capacitor. When the power is powered, the bee tweeter work sounds, and the two groups of coils are powered on at the same time. Due to the opposite direction of the current, the coil magnetic flux offsets each other, and the contacts are closed. As the capacitor continues to charging the voltage at both ends gradually increased, the current of the coil L2 is reduced. When the voltage at both ends of the capacitor is retracted the power of the contact at zero, the bee twiser sings again, and the capacitor recharges it again. This repeated cycle, the reversing bee tweee will make a discontinuous "beep, beep" sound.

This is the working principle of the reversing beeurgeer. With the advancement of technology, the reversing beeurger is also improving, and there are some other sounds of the reversing beeurgeer, rather than a single alarm sound. For example, there are voice now there are voice. The reversing alarm can have voice reminders, but although the product types are different, the basic working principle is still the same.
