China's first professional speaker diaphragm coating manufacturers

The sound film coating low grade plastic sound box because its box body is thin, cannot overcome the resonance, does not have the sound quality to speak at all (also has the part good design plastic sound box to be far better than the inferior wood sound box; 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. The sound film is coated with a small loudspeaker which is responsible for the output of the middle and high tone while the other larger speaker is responsible for the output of the middle and low tone. The material of these two speakers should be taken into account in the selection of speakers: the high-pitched units of the multimedia active speakers are now dominated by soft ball tops (in addition, titanium film ball tops used to simulate sound sources, 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. Bass unit it determines the sound characteristics of the speaker, the selection is relatively important, sound film coating the most common are the following: paper basin, and coated paper basin, paper based wool basin. Tight pressing basin, etc. Paper basin timbre natural, cheap, better rigidity, light material sensitivity, shortcomings is poor moisture resistance, manufacturing consistency is difficult to control. But top HiFi systems are made with paper pots 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.
