Features of Transducer
There are many types of Buzzers in the world. But we can divide all them into two types. Buzzer with drive circuit built in type and buzzer with external drive type which is also called as transducer. Transducer use the principle of the piezoelectric effect to make sound.
Advantages of SMD Buzzer
SMD buzzer is the type of buzzer. The size of the product is small, and it is packaged in tape and reel. The structure is stable. SMD buzzer has the advantages of small size, crisp sound, high reliability, and easy SMT mounting by more and more customers choose to use.
Advantages of Piezoelectric Buzzer
Today we are talking about the advantages of piezoelectric buzzer compared with other types of buzzers. Piezoelectric buzzer is mainly composed of multi-harmonic oscillator, piezoelectric buzzer, impedance matching device and resonance box, shell, etc.
How to Tell If a Buzzer Is Bad or Faulty
There are active buzzer and passive buzzer. The former built-in audio oscillator, thus the use of external audio source is not required. The active buzzer can make sound once with power supply. While the passive buzzer requires an external audio signal source to issue sound.
