Magnetic Buzzer

Magnetic buzzer is an electronic audio component composed of a coil, a magnet, a metal plate, and an outer shell. When the coil is energized by a current, it generates a magnetic field, which moves the metal plate against the magnet to produce repeated buzzer sounds and serve as a warning or reminder. Magnetic transducer buzzers have the characteristics of low voltage and high dB levels.


As a leading magnetic buzzer manufacturer in China , Shenghui Electronic specializes in the design and production of high-performance magnetic transducer buzzer solutions. Our magnetic buzzer product range covers both SMD (Surface Mount) and through-hole configurations, including active and passive magnetic buzzer types, engineered for reliability and clear audio output in demanding environments.


Ideal for home appliances, industrial controls, automotive electronics, and medical devices, our magnetic transducer buzzers are characterized by low voltage drive capability and consistent sound pressure levels. We offer extensive OEM/ODM support, allowing for customization of specifications such as voltage, frequency, and dimensions to meet your exact PCB integration needs. 


FAQs about

How to use Magnetic Buzzer Transducer

To use a magnetic buzzer transducer, first identify its operating voltage (common ratings: 3V, 5V, 12V). Connect the positive terminal to the corresponding DC power supply and the negative terminal to ground. Since magnetic buzzers typically require a DC

What does a magnetic buzzer do?

A magnetic buzzer converts electrical energy into sound using electromagnetic principles. When a current passes through the internal coil, it creates a magnetic field that interacts with a permanent magnet, causing a diaphragm to vibrate and produce audib

What's the Difference Between Piezo vs Magnetic Buzzers?

Piezo Buzzers​ use a piezoelectric ceramic element that vibrates when voltage is applied, producing sound. They are typically more power-efficient, operate at a wider frequency range, and are often thinner and lighter. They are ideal for high-pitched, cle
