| titleOfInvention | Edge of speaker diaphragm and manufacturing method thereof |
| abstract | (57) [Summary] [PROBLEMS] When an annular part is punched, an unnecessary part of a material has a small margin for punching, a product yield rate is high, a cost can be reduced, and an unused part is treated as industrial waste. In addition, there is no environmental problem, and there is little quality unevenness in performance as an edge, the generation of distorted sound due to partial resonance is eliminated, and the variation of the fundamental frequency (f 0 ) is eliminated. Also, Easily change, correct, or correct the elasticity (compliance) of vibration of the diaphragm, and suppress the resonance of the diaphragm by partially and consciously changing the hardness (stiffness) of the edge 6 in the circumferential direction. On the contrary, it is possible to change the frequency characteristic of the speaker by enhancing the resonance of the diaphragm. SOLUTION: A woven fabric serving as a base fabric is coated with a weather-resistant resin by screen printing means and embedded in the fibers of the woven fabric to form a first layer. The second layer of the damping resin is laminated by the same means, and a synthetic resin having another property is further laminated thereon by the same means, and the first layer or the second layer is superficially formed. The thickness was changed in a concentric pattern, and in a circumferential direction, the thickness was partially changed like a mottled pattern. |
