12*6.5mm DC type magnetic buzzer, pin terminal with oscillator circuit
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.
As a type of electronic buzzer with integrated structure, buzzers, which are supplied by DC power, are widely used in computers, printers, photocopiers, alarms, electronic toys, automotive electronic devices, telephones, timers and other electronic products for voice devices. Buzzers can be categorized as active and passive ones.
Difference between active and passive:
An active buzzer has a built-in oscillating source, so it will make sounds when electrified. An active buzzer can be connected just like an LED, but as they are a little more robust, you won’t be needing a resistor to protect them.
Difference between piezo buzzer & magnetic buzzer:
|Piezo buzzer||Magnetic buzzer|
|Start method||Piezoelectric effect||Electro-magnetic effect|
|Sound output at 10cm||dB||≥80||≥83||≥85||≥85||≥85||≥87|
