A diaphragm for acoustic instruments such as speakers is produced by blending and kneading a thermoplastic resin such as polyvinyl chloride resin with graphite powder, rolling the blend into a sheet until graphite particles are oriented, and forming the sheet into a desired diaphragm shape. The diaphragm of the composite material containing graphite particles oriented shows an improved combination of density, elasticity and internal loss. |
