The most common market, there are four kinds of the buzzer:

1 kinds of sub-section shape is the encapsulation of soft start (to start bonding), this buzzer cheaper (about 0.30 yuan market around this price is for reference only); this type of non-performance of buzzer stability, the more obvious environmental impacts, such as vibration during transport, the production line welding (this product can not have wave or dip tin), high temperature (60 degrees) or low (-20 degrees) environment use; and anti-poor, such as the surrounding magnetic elements (in the week, coil inductors, transformers, magnets, etc.), the above situation will affect the buzzer sound quality, ranging from sand change the sound or the sound does not ring when the ring re – no sound, the buzzer is more suitable for the use of low-end electronic products.
Section is divided into two kinds of body entrapment hard to start (combination of control to start), this buzzer affordable (roughly 0.45 yuan market, this price is for reference only); this buzzer stability than the first better. This buzzer is more suitable for mid-range electrical and electronic products.

The first three kinds of size is a single-tube encapsulation hard to start (to start a combination of tube), the buzzer on the price (market price of about 0.65-1.00 million, this price is for reference only) for this buzzer better environmental adaptability, and the Baptist may have been wave soldering tin, but the anti-interference performance is not ideal.

No. 4 is a hardware encapsulation type used to start two-pipe (combination of two pipes to start), the buzzer prices higher (1.00-2.00 yuan market, this price is for reference only) this type buzzer usually high temperature of the plastic shell and the anti-coil, magnetic ring to produce, buzzer on the environment to adapt to such a good performance, low non-performing. Suitable for the use of high-end electronic products.
