Abstract
The present disclosure provides a method for manufacturing a compound diaphragm. The method comprises the following steps: providing a sheet made of macromolecular material; providing damping glue; blending powdered graphene into the damping glue; and coating the damping glue blended with the graphene onto a surface of the sheet made of macromolecular material to form a compound diaphragm. The method is simple, has a low production cost, and can provide a compound diaphragm with high strength and superior performances.
