SMT buzzer:
The buzzer Audio Indicator and Alerts is divided into active buzzer and passive buzzer. The passive buzzer(SMD Transducer) is not divided into positive and negative, and the active buzzer(SMT PIEZO BUZZER) is divided into positive and negative.
The passive buzzer is similar to a horn. As long as the electrical signals of different frequencies are loaded on the two legs, the sound can be realized. To change the sound of the passive buzzer, the sound can be made different according to different frequencies; For the active buzzer with positive and negative poles, as long as the voltage signal is added to the two pins, it will sound. However, compared with the passive buzzer, the sound emitted by the Piezoelectric Internal Buzzer is not only single tone, but also fixed frequency.
Application fields of buzzer of famous Chinese brand FBelec
Buzzer is an electronic buzzer with integrated structure, which belongs to a kind of electronic components. It is powered by DC voltage or AC voltage. It is widely used in computer industry (motherboard buzzer, chassis buzzer, computer buzzer), printer (control board buzzer), copier and alarm industry (alarm buzzer).
Electronic toys (music buzzer), agriculture, automobile electronic equipment industry (vehicle buzzer, reversing buzzer, automobile buzzer, motorcycle buzzer), telephone (environmental protection buzzer), timer, air conditioner, medical equipment and other electronic industries.
FBelec'S SMT buzzer has the characteristics of small volume and high sound pressure. It can be used for automatic production and high temperature resistance. It is suitable for wave soldering and IR reflow soldering. The smallest size is 3 * 3
In the model number of SMT1230," SMT" mean surface mounting,"12" means the diameter of the buzzer,"30" means the height of the SMD buzzer.
