95dB High Decibel Continuous Electronic Buzzer Alarm DC12V DC24V
DC12V DC24V Electronic Buzzer Alarm Sounder 95dB High Decibel
Continuous Electronic Alarm Buzzer
Electronic Alarm Buzzer
Description:
The piezoelectric buzzer is mainly composed of a multivibrator, a
piezoelectric buzzer, an impedance matching device, a resonance
box, an outer casing and the like. Some piezoelectric buzzer
housings are also equipped with light-emitting diodes. A
multivibrator is composed of a transistor or an integrated circuit.
When the power is turned on (1.5~15V DC working voltage), the
multivibrator starts to oscillate and outputs an audio signal of
1.5~2.5kHZ
Piezoelectric buzzers can be divided into: passive piezoelectric
buzzer (external drive series), active piezoelectric buzzer
(including drive series), and self-excited piezoelectric buzzer.
The characteristics of the piezoelectric buzzer are: small size,
light weight, thin thickness, low power consumption, good
reliability, and low cost.
It is suitable for sounding devices on small electronic products
such as electronic watches, pocket calculators, electronic
doorbells and electronic toys. Electronic clocks, electrical
products, burglar alarms, downhole alarms, smoke alarms and the use
of electronic toys. It can also be used as an acoustic sensor for
voice-activated toys.

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.
