▎ 摘  要

NOVELTY - The utility model claims a composite vibration film structure, the composite vibration film structure from top to bottom orderly comprises: a graphene layer, an upper adhesive layer, a metal thin film layer, a lower adhesive layer and a high molecular thin film layer; the thickness ratio of the total thickness of the graphene layer, the upper adhesive layer and the metal thin film layer to the polymer thin film layer is 3 to 5: 1. through the composite vibration film structure, which can make the middle-high audio performance of the micro-speaker more stable; at the same time, effectively reducing the distortion problem.
