What is electromagnetic transducer

Magnetic transducer is an electrical component that converts electric energy into sound signal (sound wave), and can be used in the environment with slightly corrosive gas and dust. Electromagnetic transducer is a miniature electroacoustic converter without sound source. It is used in alarm, electronic clock, electronic toys and other fields.

Structural working principle of Magnetic transducer

1) Electromagnetic buzzer works by using electromagnetic principle;

2) It is composed of coil, magnet, vibrating diaphragm, etc;

3) When the wire supplies audio current to the coil, an alternating magnetic field is generated, and the vibrating diaphragm vibrates and makes sound under the attraction of the alternating magnetic field;

4) The shell of the electromagnetic buzzer forms a common sound cavity to make its sound louder;

5) The sound source integrated circuit IC is included inside;

6) After the specified DC working voltage is connected, the IC generates audio signals (continuous long sound and intermittent sound) to drive the buzzer to sound

The difference between music buzzer and electronic buzzer

(1) The electronic buzzer is composed of discrete components. The core component of the music buzzer is the music integrated circuit (the discrete components are packaged together).

(2) When the switch s of the electronic buzzer is pressed, the music integrated circuit can drive the piezoelectric ceramic chip to make music. The electronic buzzer only emits the beeping sound with a single frequency, while the music buzzer can emit the music sound of reading the ear. Therefore, this kind of buzzer is called music buzzer.

Working principle of magnetic transducer

Electromagnetic transducer consists of an oscillator, electromagnetic coil, magnet, vibrating diaphragm, and casing. After applying appropriate voltage to both ends of the coil, current flowing through the coil will generate a magnetic field, which causes deformation of the metal diaphragm. If a changing current is provided, the magnetic transducer buzzer will emit a sound. Battery based magnetic transducer can be divided into active and passive buzzers based on whether there is an internal vibration source. The active magnetic transducer has an internal oscillation source, which only requires applying appropriate voltage to both ends of the coil; The passive magnetic transducer does not have an internal vibration source, so it needs to be driven externally by a square wave. Changing the square wave frequency can change the sound.

What does customer say about FBELE Company


Before we found FBELE, we cooperated with another factory manufacturer. Due to the quality problem at that time, we tried to cooperate with FBELE. Unexpectedly, the quality of FBELE products is very stable. At present, the cooperation has been nearly 10 years. We hope FBELE will always supply us.


Our cooperation with FBELE is because it can provide us with one-stop service, which can help us organize the goods of other factories in China to be transported to Brazil. At the same time, it can also help our company pay on behalf of us and solve our worries.
