摘要:
A speaker diaphragm or a dust cap formed by injection molding a mixture at least containing a resin material and a fiber material. The speaker diaphragm or the dust cap combines the advantages of both a paper diaphragm and a resin diaphragm. The advantage of a paper diaphragm is a large degree of freedom in setting physical properties. The advantages of a resin diaphragm are being excellent in moisture resistance reliability, strength, external appearance, productivity and dimension stability.
