Abstract:
A speaker cone assembly comprises a felted paper-type cone fabricated of a composite material and a molded surround. The composite cone material contains natural fibers and synthetic fibers, where the synthetic fibers are able to chemically bond to material of the surround, thereby forming an improved bond during the molding procedure by which the surround is formed and attached to the cone.
