▎ 摘  要

NOVELTY - Graphene speaker cone, is claimed. The material of the graphene speaker cone is pulp and the pulp is mixed with 0.5-3% of graphene powder. USE - The graphene speaker cone is useful in a speaker (claimed). ADVANTAGE - The graphene speaker cone improves the product quality of the speaker and improves the service life of the speaker and is not easily damaged. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing the graphene speaker cone, comprising (i) soaking the raw material pulp, (ii) using a pulper to crush the soaked raw material pulp to obtain a semi-finished pulp, (iii) adding 0.5-3% graphene powder into the semi-finished pulp to the dry weight of the pulp and stirring uniformly, (iv) adding a water repellent into the semi-finished pulp and stir evenly, (v) adding aluminum sulfate powder to the semi-finished pulp and stirring uniformly to obtain a finished pulp, and (vi) manufacturing the speaker cone using the finished pulp.
