NOVELTY - The utility model claims a composite sound film structure, the composite sound film structure comprises a base material layer and a graphene layer adhered on the surface of the base material layer, the graphene layer is a net-shaped structure, and the graphene layer far away from one side surface of the base material layer is provided with a silk film layer. the thickness of the silk film layer is less than 0.3 mm; the thickness of the base material layer is less than 0.5 mm; the base material layer, graphene layer and the silk film layer are connected by hot pressing or damping glue. the base material layer of the composite sound film structure is provided with a graphene layer of the net-shaped structure, which effectively reduces the thickness of the composite sound film structure and improves the structure strength of the composite sound film structure; the reliability is higher; the outer side of the graphene layer is provided with a silk film layer; obviously improving the modulation effect of sound quality and timbre of the sound film, the cost performance is higher; the adhesive connection mode of the hot pressing and the damping glue makes the composite sound film structure more stable.
