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. The method of preparing the composite cone material includes formulating and refining the natural fibers, preferably before adding the synthetic fibers.

Um altofalante o conjunto do cone que compreende a felted o papel-tipo cone fabricado de um material composto e moldado cerca. O material composto do cone contem fibras naturais e as fibras sintéticas, onde as fibras sintéticas podem se ligar quimicamente ao material cercar, dando forma desse modo a uma ligação melhorada durante o procedimento do molde por que cercar é dado forma e unido ao cone. O método de preparar o material composto do cone inclui formular e refinar as fibras naturais, preferivelmente antes de adicionar as fibras sintéticas.
