The feedback buzzer is fixed as follows:
Resonance buzzer is mainly used in node support mode: the buzzer is fixed in the same size with the ceramic ring structure within the ring. If the resonator design properly, and with the correct frequency of the feedback buzzer and positive feedback circuit, will produce greater sound pressure and the correct frequency.
Non-feedback buzzer film fixed as follows:
Non-feedback buzzer is mainly used around the peripheral support, the outer diameter of the buzzer by the edge fixed in the resonant cavity, the general use of non-feedback type buzzer, and its buzzer must be with the resonant frequency , Will have a higher sound pressure output, and the external oscillator circuit to generate a push signal, so that the buzzer can make a sound.
The next analysis of the characteristics of the piezoelectric buzzer, there are the following:
1, small size + easy to carry
2, lightweight + thin thickness
3, saving + high reliability
4, the cost is reasonable
Piezoelectric buzzer related applications, mainly in the following:
1, electronic watches
2, pocket calculator
3, electronic doorbell
4, electronic toys
5, the general small electronic products
In addition we have to pay attention when choosing piezoelectric buzzer which parts, as follows:
1, its driving method: If it can not provide the frequency signal to the buzzer work, then you can consider using the drive circuit, and then give it a DC voltage on it
2, the size of the piezoelectric buzzer, what should pay attention to the size, because it may affect the frequency, and the smaller the frequency of the higher the size
3, its voltage size, the higher the voltage, the higher the volume
Then the above comprehensive information on the piezoelectric buzzer has a detailed analysis, including its working principle, classification, features, applications, and in the choice of what details need to pay attention to...
