Active electromagnetic buzzer 2300 ± 300Hz with cable, size 12*9.5mm
Description:
A buzzer is used in the domestic, official and industrial fields and it has almost entirely replaced the electro-mechanical bell. In houses and offices, the buzzer is used to catch the attention of people. In the industrial arena, it is mostly used as an alarm device.
The electromagnetic buzzer generally consists of a plastic housing with a metal diaphragm that is flexed by an electro- magnet. The main benefit of this design is the ability to obtain low frequencies in a small package. Drawbacks include mechanical wear, electrical noise, lower sound output, and large power consumption.
There are two main types of buzzer: active and passive.
An active buzzer has a built-in oscillating source, so it will make sounds when electrified. But a passive buzzer does not have such source, so it will not tweet if DC signals are used; instead, you need to use square waves whose frequency is between 2K and 5K to drive it. The active buzzer is often more expensive than the passive one because of multiple built-in oscillating circuits.
Difference between piezo buzzer & magnetic buzzer:
A piezo buzzer generates sound because of the piezoelectric effect
from the piezoelectric ceramic which drives the metallic diaphragm
to vibrate.
A magnetic buzzer is based on the electromagnetic principle, the
metal diaphragm is pulled when input the power, and spring back
without power.
The piezo buzzer is driven by square waves, and the magnetic buzzer
needs 1/2 square waves to drive.
