Polymer-Graphite Composite Loudspeaker Diaphragm

Document Thumbnail

A polymer-graphite composite has been developed which has both a high E/p ratio and a large internal loss factor. The specific modulus (E/p) of the composite is higher than that of aluminum or titanium, and the internal loss (tan8) is larger than that of cone paper. Since the composite is good in formability, it can be molded into various shapes of low-frequency or high-frequency loudspeaker diaphragms. By the use of the composite, superior loudspeakers have been realized which have smooth frequency response, very low harmonic distortion characteristics and wide dynamic range.
