Embodiment Construction
[0011] 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.
[0012] This application proposes an embodiment of a moisture-resistant paper cone for a speaker, which at least includes a combination of polyvinyl chloride, polyester fiber, and lignin.
[0013] In the above examples, in parts by weight, there are 100 parts of polyvinyl chloride, 58-60 parts of polyester fiber, and 15-16 parts of lignin. Lignin can be extracted from various woods. The combination of polyester fiber and lignin can not only exert their respective advantages, but also synergistically produce new modification effects. The three components in this case can effectively improve the tensile strength, moisture resistance and elastic modulus of the paper cone. Increase the elastic modulus of the paper cone, reduce the loss coefficient of the paper cone, thereby reducing the di...
