What is Magnetic Buzzer
Electromagnetic buzzer: with 1.5V, it can emit sound pressure of more than 85dB, but the current consumption will be much higher than that of piezoelectric buzzer. When the size is the same, the response frequency of electromagnetic buzzer can be relatively low; The sound pressure of electromagnetic buzzer is generally up to 90dB
Why use Magnetic Buzzer
Due to the product structure, generally speaking, the cost of electromagnetic buzzer is lower than that of piezoelectric buzzer
Due to the product structure, generally speaking, the size of electromagnetic buzzer can be made relatively small.
Electromagnetic buzzer has the characteristics of long service life and long working time
The special The energy consumption of electromagnetic buzzer is relatively low,
The difference between piezo buzzer and magnetic buzzer
Buzzers are divided into two categories: piezoelectric and electromagnetic: piezoelectric buzzers make sound by driving the vibration of metal sheets with the piezoelectric effect of piezoelectric ceramics; The electromagnetic buzzer uses the principle of electromagnetism to suck down the metal diaphragm when it is powered on and bounce back according to the elasticity of the diaphragm when it is not powered on. Therefore, the piezoelectric buzzer is driven by square wave and the electromagnetic buzzer is driven by 1 / 2 square wave. The piezoelectric buzzer needs relatively high voltage to have enough sound voltage. Generally, it is recommended to be more than 9V. Some specifications of piezoelectric can reach more than 120dB, and larger ones can easily reach 100dB.
Structure of electromagnetic buzzer
According to the structure,Magnetic buzzer can be divided into:
- Passive electromagnetic buzzer On the contrary, it is suitable for higher current consumption specifications / higher frequency range to respond and sound with better sound quality (about 40 ~ 80mA * 500Hz).
- Active electromagnetic buzzer Active (self-excited) buzzer vibration coil and oscillation coil are combined into one.

Genaral Questions About Magnetic Buzzer
Electromagnetic buzzer is a common sounding component in the design of electronic products. It is widely used in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products.
The electromagnetic buzzer mainly uses the characteristics that the energized conductor will generate a magnetic field, and uses a fixed permanent magnet and the energized conductor to generate a magnetic force to push the tympanic membrane fixed on the coil. Electromagnetic type is mostly used in voice, music and other equipment because of its good timbre.
passive
On the contrary, it is suitable for higher current consumption specifications / higher frequency range to respond and sound with better sound quality (about 40~80ma*500hz).
Active
Active (self-excited) buzzer vibration coil and oscillation coil are combined into one.
The electromagnetic buzzer has high reliability, and is mainly supported by vehicle mounted products. Because of the pin terminal type, it can be directly installed on the printed substrate, with small φ 12type, and designed for wide band φ 16Type。 At the same time, we also have SDR series products to meet the needs of reflow packaging.
There is no sound or no sound after welding. This situation may be caused by the excessive power of the soldering iron used in the welding process (it is recommended to use 20-30w soldering iron) or the long time (it is recommended to complete a welding spot within 3 seconds), resulting in the heating and melting of the buzzer pin and the welding point of the coil.
