Acoustically Enhanced Electro-Dynamic Loudspeakers
US Patent:
2005015, Jul 21, 2005
Filed:
Jan 19, 2005
Appl. No.:
11/039476
Inventors:
John Steere - Martinsville IN, US
David Garner - Indianapolis IN, US
Steven Hutt - Bloomington IN, US
David Garner - Indianapolis IN, US
Steven Hutt - Bloomington IN, US
International Classification:
H04R001/00, H04R009/06
US Classification:
381431000, 381423000
Abstract:
An electro-dynamic loudspeaker is provided with dampening arrangements that contribute to improved acoustical properties for the electro-dynamic planar loudspeaker. The dampening arrangements include providing a frame having a curved sidewall surface for reducing standing waves. Another design provides for a ferrofluid being disposed between the diaphragm and magnets of the electro-dynamic loudspeaker in order to dampen the resonance frequency of the device. In addition, a diaphragm of an electro-dynamic loudspeaker is provided with a short turn of conductor disposed along a fringe zone at an edge of the diaphragm in order to electro-dynamically dampen the edge resonance of the film.
Core Cap For Loudspeaker
US Patent:
7400740, Jul 15, 2008
Filed:
Feb 14, 2005

Assignee:
Harman International Industries, Inc. - Northridge CA
International Classification:
H04R 1/00, H04R 9/06
US Classification:
381414, 381412
Abstract:
A core cap or top plate for use with loudspeakers that includes offset adhesive control grooves on the opposite faces of the disk-like core cap is disclosed. The grooves are offset from one another by a distance that makes the smallest dimension between any feature of the grooves about the same as the nominal thickness of the core cap. The core cap increases the magnetic flux capacity over prior art core cap designs, while maintaining features advantageous to error-proof the orientation of the core cap in the loudspeaker.
Acoustic Lens System
US Patent:

Assignee:
Harman International Industries, Incorporated - Northridge CA
International Classification:
G10K 11/08, H04R 7/06, H04R 1/28
US Classification:
181176, 381356, 381357, 381431, 381396, 381191, 381391
Abstract:
A loudspeaker includes a frame, a magnet coupled to the frame and a diaphragm secured to the frame. An acoustic lens may be positioned in front of the diaphragm. An aperture extends through the acoustic lens. The acoustical directivity pattern of the loudspeaker may be modified by the acoustic lens to improve the uniformity of the off axis vs. on axis sound pressure level.

International Classification:
H04R001/00, H04R009/06, H04R011/02
US Classification:
381/423000, 381/398000
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:
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.

Harman International Industries, Incorporated - Northridge CA
International Classification:
H04R 1/00, H04R 9/06
US Classification:
381412, 381414
Abstract:
A magnet structure for use with a loudspeaker has an interlocking mechanism. The magnet structure can include a magnet, a shell pot and at least one core cap. The shell pot can contain the magnet in its hollow interior. The magnet can be a single magnet or double magnets. The core cap has two surfaces. For a single magnet, one surface of the core cap faces the magnet. For double magnets, the core cap can be vertically disposed between the two magnets. The magnet, the core cap and the shell pot can interlock with one another such that a position of the magnet relative to the core cap and the shell pot can be rigidly preserved. The magnet can be configured to be, for example, overlapped, inserted, staked and/or engaged with at least one of the shell pot or the core cap.

H04R 1/00, H04R 9/06, H04R 11/02, H04R 25/00, H04R 7/00, G10K 13/00
US Classification:
381423, 381150, 381398, 181167
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.
