▎ 摘　　要

NOVELTY - A speaker consists of a frame having a predetermined opening, a diaphragm (a) coupled to one side of the frame, and a diaphragm (b) coupled to the other side of the frame. The diaphragms (a) and diaphragm (b) comprise a graphene layer patterned in a spiral structure, a polymer layer formed on one surface of the graphene layer, and a conductive metal layer formed on the other surface of the graphene layer. USE - Speaker (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of diaphragm.
