Integrated Electromagnetic Buzzer / 85DB 5v Active Buzzer With Waterproof Sticker

12*9.5mm 5V integrated active buzzer 85dB with waterproof sticker

Description:

Buzzer is a signaling device that is not a loudspeaker. It can be mechanical, electromechanical, or electronic (a piezo transducer). When a lower frequency is required an electromagnetic buzzer can fill the need. These are very common in automotive chimes and higher end clinical diagnostic devices. An electromagnetic buzzer provides good sound output starting at 800Hz.

A magnetic buzzer is based on the electromagnetic principle, the metal diaphragm is pulled when input the power, and spring back without power. 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 difference between an active buzzer and a passive buzzer:

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.
