What should be paid attention to when welding active buzzer?

2022-02-28

What should be paid attention to when welding active buzzer? Buzzer is divided into active and passive two kinds, the working principle is different. Here we have a detailed look: 1. active buzzer, also known as piezoelectric buzzer, by the multi vibrator, piezoelectric buzzer, impedance matching box, resonator and shell composition. The most important of these is its piezoelectric buzzer, which is a piezoelectric ceramic that can stop the conversion of electrical and mechanical energy.

What are the working principles of electromagnetic buzzer

2021-12-14

The alternating current signal of the electromagnetic buzzer generates alternating magnetic flux on the rod of the bracket through the wire wound on the bracket. The alternating magnetic flux overlaps with the constant magnetic flux of the magnet ring, so that the molybdenum sheet vibrates at the specified frequency of the alternating current signal. Together with the resonator to produce sound, then, let's learn about the working principles of the electromagnetic buzzer!

The difference between active buzzer and passive buzzer

2021-11-29

The buzzer is a commonly used pronunciation device, which is commonly used in the microcontroller experiment board and children's toys. Is it distinguished from the sound? Some only emit sounds of a certain frequency, while others emit clear sounds. So, let's understand the difference between active buzzer and passive buzzer!

Passive buzzer buzzer related knowledge

2021-10-29

A passive buzzer is an integrated structure electronic sounder, powered by a DC voltage. It is widely used as a sound generating device in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products. Passive buzzer is mainly divided into two kinds: piezoelectric buzzer and electromagnetic buzzer. The buzzer is represented by the letter "h" or "HA" in the circuit.
