  • Method for manufacturing loudspeaker diaphragm
    Patent number: 5047191
    Abstract: A felted paper loudspeaker diaphragm in which the felted paper of the annular supporting flange is thinner, and of lesser density and higher compliance then the cone body. The supporting flange is permeated with a high compliance elastomer which provides most of the tensile strength of the supporting flange.
    Type: Grant
    Filed: July 30, 1986
    Date of Patent: September 10, 1991
    Assignee: Fibre Form Corporation
    Inventors: Neal L. Baitcher, Robert M. Brennan

  • Loudspeaker having a unitary mechanical-acoustic diaphragm termination
    Patent number: 4319098
    Abstract: The periphery of the diaphragm of a loudspeaker is mechanically connected to a diaphragm support or basket by a layer of acoustic dampening-adhesive material. The layer of acoustic dampening-adhesive material covers a sufficient portion of the surfaces of the diaphragm to dampen standing waves which would otherwise reflect from the periphery of the diaphragm. Thus, a unitary diaphragm mechanical termination-acoustic termination structure is formed.
