China's first professional speaker diaphragm coating manufacturers

Sound film coating materials are widely used in the field of sound, with the improvement of living standards, the sound effect requirements are higher and higher. At present, the sound film materials are mainly paper, plastic. Aluminum and titanium and other materials made of beryllium foil sound effect is the best. This is due to the high elastic modulus of beryllium. Therefore, many people are exploring the use of beryllium foil to make sound film materials. However, because beryllium is difficult to be made into foil with hexagonal structure, it has not been widely used. So far only one American company in the world has been able to produce beryllium sound film materials. This is a good opportunity for us to develop and utilize this material. Loudspeaker sound film coating size is naturally the larger the better, the larger the bass loudspeaker can be in the low frequency part of the better performance. This is optional. Speakers made of high-performance loudspeakers mean lower transient distortion and better sound quality. The average multi-media loudspeaker has speakers ranging from 3 to 5 inches. High-performance loudspeakers also mean lower transient distortion and better sound quality. PP (polypropylene) basin, sound film coating is widely popular in high-grade speakers, good consistency and low distortion. The performance is remarkable in all respects. In addition, such as fibrous diaphragm and composite diaphragm are rarely used in popular speakers because of their high price.
