Classification of buzzer :
1. According to the principle of its driving mode, it can be
divided into: active buzzer (including driving circuit, also called
self-excited buzzer) and passive buzzer (external drive, also
called other excited buzzer) Sounder);
2. According to the different construction methods, it can be
divided into: electromagnetic buzzer and piezoelectric buzzer;
3. According to the different packages, it can be divided into: DIP
BUZZER (Pin Buzzer) and SMD BUZZER (SMD Buzzer);
4. According to the difference of current, it can be divided into:
DC buzzer and AC buzzer. Among them, DC is the most common
piezoelectric buzzer, which uses piezoelectric material, that is,
when the external force causes the piezoelectric material to occur
Piezoelectric materials generate electrical charges during
deformation. Similarly, piezoelectric materials deform when
energized.
The electromagnetic buzzer mainly uses the characteristics of the
conductive conductor to generate a magnetic field, and uses a fixed
permanent magnet and the conductive conductor to generate magnetic
force to push the tympanic membrane fixed on the coil.
Due to the different sounding principles of the two buzzers, the
piezoelectric structure is simple and durable but has a single tone
and color difference. It is suitable for devices such as alarms.
The electromagnetic type is mostly used for voice, music and other
equipment because of its good timbre.
