▎ 摘　　要

NOVELTY - The diaphragm has a diaphragm substrate layer, and a graphene layer adhered to a surface of the diaphragm substrate layer. A graphene loudspeaker membrane is provided with a ball top and connected with a ball top part of a circumferential direction of a folded ring part, where an edge of the folded ring part horizontally extends outwards to form a connecting part. The folded ring part is provided with a ring rib annular array. USE - Graphene speaker diaphragm for an earphone. ADVANTAGE - The diaphragm enables large-angle bending while preventing irreversible deformation, provides superior endurance to large pressure and enhances diaphragm strength, thus improving acoustic output performance of the speaker. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene speaker diaphragm.
