Acoustic Loudspeaker

US Patent:
7443995, Oct 28, 2008
Filed:
Feb 17, 2005
Appl. No.:
11/060143
Inventors:
Burton Babb - Dallas TX,
Alan Babb - Dallas TX,
Assignee:
Babb Laboratories - Dallas TX
International Classification:
H04R 1/00
US Classification:
381396, 381409, 381410, 381412, 381414
Abstract:
An acoustic driver has a voice coil in which adjacent turns of the coil are spaced apart. The driver is placed at one end of a foam-lined, elongated structure, such as a tube. An opposing end of the structure is, in one embodiment, enclosed by a wall that is connected to the structure by a suspension so that it moves in sympathy with the driver. In another embodiment, the structure cooperates with the acoustic driver to form one or more restrictive passageways confined around the driver's motor and an inner surface of the structure. The passageway(s) couple a volume of air in the structure to the exterior of the structure in a manner that reduces the transmission of acoustic energy without creating alternating pressure within the structure that interferes with the movement of the voice coil's diaphragm, at its maximum points of excursion.

Vortex Cooling Of Voice Coils

US Patent:
8577074, Nov 5, 2013
Filed:
Feb 14, 2011
Appl. No.:
13/026374
Inventors:
Alan Babb - Burnsville MN,
Assignee:
Robert Bosch GmbH - Stuttgart
International Classification:
H04R 1/00
H04R 9/06
H04R 11/02
US Classification:
381397, 381412
Abstract:
A low frequency transducer arrangement includes at least one substantially annular magnet. A voice coil is disposed within and concentric with the magnet. A pole is disposed within and concentric with the voice coil. An air gap is defined between the magnet and the pole. The pole includes a bottom half having a downwardly facing axial recess. A plurality of first air passages extend laterally from the axial recess and fluidly interconnect the recess and the air gap. A top half has an upwardly facing axial recess. A plurality of second air passages extend laterally from the upwardly facing axial recess and fluidly interconnect the upwardly facing recess and the air gap. The first air passages and/or the second air passages are non-radially oriented.

Acoustic Loudspeaker With Energy Absorbing Bearing And Voice Coil, And Selective Sound Dampening And Dispersion

US Patent:
2001003, Oct 25, 2001
Filed:
Feb 21, 2001
Appl. No.:
09/790332
Inventors:
Burton Babb - Dallas TX,
Alan Babb - Richardson TX,
International Classification:
H04R001/00
H04R011/02
US Classification:
381/401000, 381/396000
Abstract:
A loudspeaker having a flux gap defined by central pole and a magnet surrounding the central pole, includes a plurality of low-friction ridges extending from an outer surface of a the central pole. A voice coil, connected to the loudspeaker's diaphragm, is free to reciprocate within the flux gap. The ridges are linear and run generally in an axial direction, along a length of the pole where the voice coil reciprocates. Instead of rubbing directly against a metal pole, which has relatively high friction, the voice coil will rub against the ridges, thus reducing some of the noise that would otherwise occur due to rubbing. The voice coil includes a relatively stiff structure, created in part with a ceramic or epoxy material, that is coupled to a diaphragm, and a relatively flexible multiple layer structure at the terminating free end having dampening properties.

Acoustic Loudspeaker

US Patent:
2002009, Jul 18, 2002
Filed:
Oct 30, 2001
Appl. No.:
09/997416
Inventors:

International Classification:

Multiple Magnetic Air Gap Motor

US Patent:
2012020, Aug 16, 2012
Filed:
Feb 14, 2011
Appl. No.:
13/026394
Inventors:
Alan Babb - Burnsville MN,
Assignee:
Robert Bosch GmbH - Stuttgart
Bosch Security Systems Inc. - Fairport NY
International Classification:
H04R 1/00
US Classification:
381400, 381396
Abstract:
A low frequency transducer arrangement includes a substantially cylindrical structure surrounding a pole piece. The pole piece and the substantially cylindrical structure define a substantially cylindrical air gap therebetween. Two opposite ends of the air gap are both open and separated from each other in an axial direction. A first magnet is disposed in either the pole piece or the substantially cylindrical structure. A second magnet is separated in the axial direction from the first magnet by a middle magnetic gap. The second magnet is disposed in either the pole piece or the substantially cylindrical structure. The first and second magnets provide flux in a same direction in the middle magnetic gap. A top magnetic gap is disposed axially adjacent the first magnet and opposite the middle magnetic gap. A bottom magnetic gap is disposed axially adjacent the second magnet and opposite the middle magnetic gap. A voice coil is at least partially disposed in the air gap and operates in the middle magnetic gap.
