Abstract
The present disclosure provides diaphragm and a method for manufacturing the same. The diaphragm includes a first macromolecular material layer, a graphene layer, a glue layer and a second macromolecular material layer in sequence. The first macromolecular material layer is directly attached to the graphene layer, and the second macromolecular material layer is attached to the graphene layer via the glue layer. The strength and the stiffness of the diaphragm is enhanced to improve the acoustic performances of the diaphragm.
