BUZZER application field

BUZZER application field

Buzzer is mainly used to prompt or alarm, take your washing machine for example, the operation of the washing machine starts and ends, there will be a sound, and some equipment has been prompted DI,DI,DI, etc., when there is no electricity, there are more types of buzzers, here let's say the most common one. The most common is divided into electromagnetic buzzers and electronic honey machines according to the principle of structural performance. There is a patch buzzer that is relative to the plug-in package, which is not expanded here.

To name a few examples, electromagnetic buzzers are generally used in toys, doorbells, electronic clocks above, electromagnetic buzzer consumption current is generally between 25-80MA, voltage 1.5V,3V,5V,9V,12V mostly,

Piezoelectric buzzer contrast magnetic buzzer, the biggest advantage is the low current consumption, be in commonly 2 to 5 ma consumption current, so it's save electricity, commonly used in some of the portable electronic products, such as thermometer, temperature guns, machine ETC,

The general voltage of the car tail door is 6V, 12V, 24V, which is more common. There are also some high-pitched buzzers that generally use piezoelectric buzzers, such as ship sirens, such as burglar alarms, smoke alarms, and so on.

There are a lot of life will be used in the buzzer, its application is very wide, many people will pick up the buzzer with the horn to do comparison, the buzzer tone is relatively single, the horn covered by the frequency segment is relatively wide, but it is relative to the horn, there are small size, cheap and other factors, so the application is also very wide.
