Advantages of piezoelectric buzzer
The piezoelectric buzzer is mainly composed of a multivibrator, a piezoelectric buzzer, an impedance matcher, a resonance box, and a shell. The multivibrator is composed of transistors or integrated circuits. When the power is turned on (1.5~15V DC working voltage), the multivibrator starts to vibrate and outputs audio signals of 1.5~2.5kHZ. The impedance matcher drives the piezoelectric buzzer, Vocalize.
Integrated electronic buzzer
The piezoelectric buzzer has the following advantages over other buzzers:
1. It has a long life and great dependability since there is no moveable contact portion. It can be used for more than 10,000 hours in a row. It’s a semi-permanent piece of equipment.
2. There is no arcing or radio frequency noise, and there is no interfering with other lines.
3. It will not generate excessive vibration as a result of loosening.
4. It is controlled by an electronic circuit, which allows it to produce a wide range of appealing sounds, analog sounds, and intermittent sounds with clean timbre and resistance to noise.
5. Current consumption is modest with voltage excitation, often less than 20mA and no more than 100mA.
6. There are two types of volume: little and huge. The component thickness is less than 1mm, and the volume can exceed 70 decibels/20cm.
7. Wide temperature range of operation.
8. The piezoelectric buzzer is simple to set up and maintain.
