Embodiment Construction
[0012] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.
[0013] This application proposes an embodiment of a fatigue-resistant elastic wave for a loudspeaker, which at least includes a combination of phenolic resin, sandalwood bark, and ethylene-vinyl acetate copolymer.
[0014] Wherein, by weight, 100 parts of phenolic resin, 18-20 parts of sandalwood bark, and 7-8 parts of ethylene-vinyl acetate copolymer. Ethylene-vinyl acetate copolymer is used to improve the toughness of the system, so that the elastic wave has high softness and moderate damping coefficient, and has good fatigue resistance, high temperature resistance, weather resistance and flame retardancy.
[0015] In the above embodiments, the number average molecular weight of the phenolic resin is preferably 40000-42000 g / mol.
[0016] In the above embodiments, the number average...
