Application Areas Of Buzzer

Buzzer is mainly used to prompt or alarm, take your washing machine for example, the washing machine operation and the end of operation, there will be a sound, and some equipment when there is no electricity also always prompt DI, DI, DI, etc., there are many types of buzzers, here it is the most common, the most common is divided into electromagnetic buzzers and electronic honey according to the principle of structural performance. There is a patch buzzer that is relative to the encapsulation of the plug-in, which will not be discussed here.
TO GIVE A FEW EXAMPLES, ELECTROMAGNETIC BUZZERS ARE GENERALLY USED IN TOYS, DOORBELLS, ELECTRONIC CLOCKS, ELECTROMAGNETIC BUZZERS GENERALLY CONSUME CURRENT BETWEEN 25-80MA, VOLTAGE 1.5V, 3V, 5V, 9V, 12V
Piezoelectric buzzer Compared with electromagnetic buzzer, the biggest advantage is low current consumption, generally in 2-5MA current consumption, so it is very energy-saving, generally used in some portable electronic products, such as thermometers, forehead temperature guns, ETC machines,
The general voltage of car tailgate is 6V, 12V, 24V, which is relatively common. There are also some that require a high pitch and generally use piezoelectric buzzers, such as the ship's whistle, such as burglar alarms, smoke alarms and so on.
Many in life will be used to buzzer, its application is very extensive, many people will compare the buzzer with the horn, the tone of the buzzer is relatively single, the frequency segment covered by the speaker is relatively wide, but it is relatively, there are small size, cheap and other factors, so the application is also very wide.
