12*9.5mm active electromagnetic buzzer 2300 ± 300Hz with long pin
Description:
A buzzer is a mechanical, electromechanical, magnetic,
electromagnetic, electro-acoustic or piezoelectric audio signalling
device.
Electromagnetic buzzers featuring high reliability consists mainly
of products that support automotive applications. They are directly
mountable to PCBs due to their pin terminals, and are available in
small φ12 type and φ16 type designed for broadband applications.
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.

Application:
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.
