Patent number: 9247368Abstract: A loudspeaker cone body made of paper may include a chemically-bound nanomaterial, such as a carbon nanotube. The carbon nanotube may be chemically bound to a functionalizing agent having a chemical group chemically bound to one or more papermaking additives, such as a sizing agent or a wet strength agent, a dry strength agent, a resin or cellulose-containing papermaking stock material typically present in a paper loudspeaker cone body, such as pulp. Acoustic-related loudspeaker performance characteristics such as stiffness to weight ratio and an acoustic damping of the loudspeaker cone body may be altered by incorporation of the nanomaterials chemically bound to the loudspeaker cone body.Type: GrantFiled: September 12, 2008Date of Patent: January 26, 2016Assignee: Harman International Industries, IncorporatedInventors: Louis A. Mango, III, Ryszard A. Pilatowski, John F. Steere, John S. Stewart

Patent number: 7945069Abstract: A loudspeaker cone body made of plastic includes a base carrier material and a filler material. The base carrier material is selected to optimize overall flow, weight and stiffness. The filler material may be a nanomaterial that provides for adjustment of process and acoustic related characteristics in the loudspeaker cone body that become relevant when the loudspeaker cone body is operated in a loudspeaker. Acoustic related characteristics that may be adjusted include a stiffness to weight ratio and an acoustic damping of the loudspeaker cone body. A predetermined weight percent of the filler material may be combined with the base carrier material to obtain repeatable desired acoustic related characteristics. The acoustic related characteristics may be adjusted by changing the predetermined weight percent of the filler material.Type: GrantFiled: November 22, 2005Date of Patent: May 17, 2011Assignee: Harman International Industries, IncorporatedInventors: Louis A. Mango, III, John F. Steere, Steven W. Hutt

Patent number: 7716808Abstract: Electro-dynamic loudspeakers typically include a diaphragm having a conductor applied to one of its surfaces where the diaphragm is secured to a frame. The conductor is connected to a power supply for providing electrical current through linear traces of the conductor that interact with magnetic fields generated by magnets that are mounted to the frame. The diaphragm is driven by a motive force created when current passes through the conductor within the magnetic field. The electrical current is varied to create an acoustical output from the electro-dynamic loudspeaker. Different methods of attaching the diaphragm are provided for simplifying the manufacturing process and for obtaining a robust electro-dynamic loudspeaker.Type: GrantFiled: December 28, 2007Date of Patent: May 18, 2010Assignee: Harman International Industries, IncorporatedInventors: Steven W. Hutt, John F. Steere, David B. Garner, Louis A. Mango

Patent number: 7203332Abstract: An electro-dynamic loudspeaker includes a frame, a plurality of magnets and a diaphragm. The frame includes a molded plastic body. The magnets may be molded into the frame in a determined configuration. The frame is mechanically coupled to the diaphragm such that the magnets are a determined distance from the diaphragm. The diaphragm may include a conductor applied to a surface of the diaphragm. The diaphragm may be driven by a motive force created when current passes through the conductor within a magnetic field formed by the magnets. The electrical current may be varied to create an acoustical output from the electro-dynamic loudspeaker.Type: GrantFiled: May 2, 2003Date of Patent: April 10, 2007Assignee: Harman International Industries, IncorporatedInventors: Steven W.

Patent number: 6224801Abstract: A method of making a speaker comprises providing a pair of dies which define between them a cavity. A first portion of the cavity receives a diaphragm of the speaker. A second portion of the cavity adjacent an outer perimeter of the diaphragm receives a fluid thermoplastic elastomer for forming a diaphragm surround. The second portion includes a perimetrally inner first region adjacent the outer perimeter of the diaphragm for receiving the thermoplastic elastomer to form a perimetrally inner flange for bonding to the diaphragm adjacent the outer perimeter of the diaphragm. The second portion includes a central second region for receiving the thermoplastic elastomer to form a connecting arch of the surround. The second portion also includes a perimetrally outer third region for receiving the thermoplastic elastomer to form a perimetrally outer flange for attachment to a diaphragm support. A diaphragm is placed between the dies. The dies are closed.Type: GrantFiled: March 21, 1995Date of Patent: May 1, 2001Assignee: Harman International Industries IncorporatedInventor: Louis A.
