NOVELTY - The utility model claims nonwoven fabric sound absorbing and sound absorbing structure, specifically relating to the technical field of nonwoven fabric, comprising a base layer, the bottom end of the base layer is provided with a flame retardant layer, the bottom end of the flame retardant layer is provided with an antistatic layer; the top end of the base layer is provided with an auxiliary sound absorbing and sound insulating structure; the sound absorbing and sound insulating structure comprises a first connecting layer; the first connecting layer is set on the top end of the base layer; the top end of the first connecting layer is provided with a graphene; the top end of the graphene is provided with a second connecting layer; the top end of the second connecting layer is provided with a carbon fibre. The utility model is provided with a first connecting layer, graphene; the second connecting layer and the carbon fibre; because the graphene and the carbon fibre have the function of absorbing sound and sound insulation, and the strength of the graphene is high and has good toughness; the carbon fibre also has the function of moisture absorption and ventilation, so that the function of absorbing sound and sound also has other characteristics, improving applicability.
