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.
