Polymer-Graphite Composite Loudspeaker Diaphragm

Document Thumbnail

A polymer-graphite composite has been developed which has both a large E/p ratio and a large internal loss factor. The specific modulus E/p of the composite is greater than that of aluminum or titanium, and the internal loss tan (symbol) is greater than that of cone paper. Since the composite forms well, it can be made into various shapes of low-frequency or high-frequency loudspeaker diaphragms. With this material, superior loudspeakers have been made having smooth frequency response, very low harmonic distortion characteristics, and wide dynamic range.
