Appl. No.:

10/429163

Inventors:

Steven W. Hutt - Bloomington IN, US
John F. Steere - Martinsville IN, US

Louis A. Mango - Trafalgar IN, US

Assignee:

Harman International Industries, Incorporated - Northridge CA

International Classification:

H04R 1/02

US Classification:

381399, 381408, 381421

Abstract:

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.

Abstract:

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.

Abstract:

A moving coil transducer is produced by wrapping an electrical conductor around a thread and weaving the wrapped thread at a selected location in a cloth with an overshot region. The cloth is formed into a spider with a region of the cloth adjacent the overshot region as a perimeter of the spider. The spider is incorporated into the moving coil transducer. Electrical contact is made to a moving coil of the moving coil transducer through the electrical conductor wrapped around the thread.

Inventors:

Louis Mango - Trafalgar IN, US
John Steere - Martinsville IN, US
Steven Hutt - Bloomington IN, US

International Classification:

H04R 9/06
H04R 11/02

US Classification:

381398000

Abstract:

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.

Appl. No.:

8/408550

Inventors:

Louis A. Mango - Trafalgar IN

Assignee:

Harman International Industries Incorporated - Northridge CA

International Classification:

B29C 4514

US Classification:

264154

Abstract:

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.
