China's first professional speaker diaphragm coating manufacturers

The low-grade plastic speaker can not overcome the resonance because of its thin body, and the sound film coating has no sound quality to speak of (there are also parts of the plastic sound box designed to be far better than the poor quality wood speakers; Wooden loudspeakers reduce the sound tone caused by the box body resonance, sound quality is generally better than plastic speakers. Usually the multimedia speaker is designed with two units and two frequencies. A smaller loudspeaker is responsible for the output of the middle and high tone while the other larger speaker is responsible for the output of the low tone. Sound film coating selection of speakers should consider the material of these two speakers: the high tone unit of the multimedia active speaker is now mainly soft ball top (in addition to the titanium film ball top used to simulate the sound source etc.). It can reduce the stiff feeling of high frequency signal with digital sound source, and give a soft, smooth and delicate feeling. The multimedia speaker is now mostly with good quality silk film and low cost PV film and other soft ball top. The bass unit, which determines the characteristics of the sound of the speaker, is relatively important to select, the most common of which are the following:. Paper basin, there are coated paper basin, paper-based wool basin, tight-pressed basin and so on. Paper basin timbre natural, cheap, better rigidity, light material sensitivity, sound film coating shortcomings is poor moisture-proof, manufacturing consistency difficult to control. But in top HiFi systems, paper pots are everywhere, because sound output is very average and reducibility is good. Bulletproof cloth, with wider frequency response and lower distortion, is the first choice for those who love strong bass. The disadvantages are high cost, complex production process and low sensitivity.
