Composite vibration diaphragm and its fabrication method
First Claim
1. A composite vibration diaphragm fabrication method, comprising the steps of:
- (a) mixing a reinforcing material, wherein said reinforcing material is a nano powder, with a holt melt adhesive to form a first mixture and to let said reinforcing material be wrapped in said hot melt adhesive uniformly;
(b) mixing said first mixture with a thermosetting adhesive to form a second mixture;
(c) coating said second mixture on a vibration diaphragm material and then heating the second mixture coated vibration diaphragm material;
(d) cooling down the coated vibration diaphragm material in which said second mixture is cured and bonded to said vibration diaphragm material.

Abstract
A composite vibration diaphragm fabrication method includes the steps of: (a) mixing a reinforcing material with a hot melt adhesive to form a first mixture and to let the reinforcing material be wrapped in the hot melt adhesive uniformly, (b) mixing the first mixture with a thermosetting adhesive to form a second mixture, (c) coating the second mixture on a vibration diaphragm material and then heating the second mixture coated vibration diaphragm material, and (d) cooling down the coated vibration diaphragm material in which the second mixture is cured and bonded to the vibration diaphragm material. Thus, when baking the second mixture, the internal hot melt adhesive will be melted and integrated with the thermosetting adhesive, and the thermosetting adhesive will also be cured, enabling the reinforcing material to be uniformly bonded to the vibration diaphragm to reinforce the strength and rigidity of the composite vibration diaphragm.
