automotive electronic buzzer direct sales manufacturers, complete styles, buzzer is an integrated structure of electronic buzzer, widely used in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products for the sound device; buzzer is mainly divided into piezoelectric buzzer and electromagnetic buzzer two types. The piezoelectric buzzer is mainly composed of multi-vibrator, piezoelectric buzzer, impedance matching box, resonance box and shell. The multivibrator is composed of a transistor or an integrated circuit. When the power is turned on (1.5~15V DC working voltage), the multivibrator vibrates and outputs an audio signal of 1.5~2.5kHZ. The impedance matching device drives the piezoelectric buzzer to sound.

What are the advantages of electromagnetic buzzer? What is it like? The advantages of electromagnetic buzzer are as follows: 1. Because there is no single-sided contact, it has a long service life and high reliability. Can be used continuously for more than 10000 hours. 2. No arc, no radio frequency noise, no interference to others. 3. No large vibration caused by loosening. 4. Accept the mastery of electronic circuits and let them produce all kinds of beautiful sounds, simulated sounds, and intermittent sounds. The tone is pure and not easily whitewashed by noise.

electromagnetic buzzer are used in where?

The electromagnetic buzzer is a kind of buzzer, which is different from the piezoelectric buzzer. The electromagnetic buzzer is an electronic buzzer that uses an electromagnetic coil to act on the buzzer, and is used as a sounding device for electronic products.

Electromagnetic buzzer related knowledge introduction

2022-09-29

The electromagnetic buzzer consists of an oscillator, a solenoid, a magnet, a diaphragm and a housing. After being energized, the audio signal current generated by the oscillator passes through the electromagnetic coil, causing the electromagnetic coil to generate a magnetic field. The diaphragm periodically vibrates under the interaction of the electromagnetic coil and the magnet, thereby emitting sound.

Passive electromagnetic buzzer

Source electromagnetic buzzer and passive electromagnetic buzzer. The internal structure of the active electromagnetic buzzer is equipped with an oscillation source. As shown in the following figure, if you take a low frequency of BUZZ pin, the electromagnetic buzzer will sound directly. The internal structure of the passive electromagnetic buzzer is no oscillation source
