Glass-Fiber and Graphite-Flake Reinforced Polyimide Composite Diaphragm for Loudspeakers

Document Thumbnail

A newly developed diaphragm material especially suitable for loudspeaker drivers is described. The new diaphragm using this material features a high Young's modulus and an appropriate mechanical loss. The diaphragm is composed of a glass-fiber fabric base with a polyimide matrix polymer and a flaked graphite filler. Young's modulus for the new diaphragm is ten times higher than that of commonly used paper pulp diaphragms, with about the same mechanical loss.
