Michael D. Rosen - Auburndale MA, US
Tobe Barksdale - Bolton MA, US
Christopher Ludwig - Northborough MA, US

Assignee:

Bose Corporation - Framingham MA

International Classification:

H04R 5/03
H04R 5/00
H04B 1/00
H02B 1/00
H03G 3/00
G10H 1/08

US Classification:

Abstract:

Systems and techniques for controlling a surround sound system having multiple input signals and multiple spatially diverse transducers may include defining a first control region and a second control region. When operating in the first control region, a first set of functions is performed. For example, for each of the spatially diverse transducers, an input signal may be selected, a relative strength of the selected input signal may be adjusted, and the adjusted input signal may be applied to the transducer. When operating in the second control region, a second set of functions is performed. For example, for each of the spatially diverse transducers, two or more input signals may be selected, a relative strength of the selected input signals may be adjusted, the adjusted input signals may be mixed, and the mixed input signals may be applied to the transducer.

Assignee:

Bose Corporation - Farmingham MA

International Classification:

H04R 25/00

US Classification:

381386, 381302, 381 86

Abstract:

An audio system including a first audio source, including a surround channel signal, coupled to an electroacoustical transducer mounted in the back of a seat of, for example, an automobile, so that the surround channel is radiated from the electroacoustical transducer. In one embodiment, the electroacoustical transducer is oriented to radiate substantially upwardly.

Appl. No.:

10/999419

Inventors:

Michael D. Rosen - Framingham MA, US
Richard Warren Little - Franklin MA, US

Assignee:

Bose Corporation - Framingham MA

International Classification:

H04R 1/00
H04R 25/00

US Classification:

381401, 381186

Abstract:

An electro-acoustic transducer includes a magnet assembly having a first magnetic flux gap and a second magnetic flux gap. A first voice coil is positioned in the first magnetic flux gap. A first diaphragm is mechanically coupled to the first voice coil and to a frame. The first voice coil moves the first diaphragm in a first direction in response to receiving a first input signal. A second voice coil is positioned in the second magnetic flux gap. A second diaphragm is mechanically coupled to the second voice coil and to the frame. The second voice coil moves the second diaphragm in a second direction that is substantially opposite to the first direction in response to receiving a second input signal. The movement of the second diaphragm reduces a vibration imparted to the frame by the movement of the first diaphragm.

Filed:

Dec 24, 1996

Appl. No.:

08/777958

Inventors:

Donald F. Hamilton - Sterling MA, US
Michael D. Rosen - Auburndale MA, US

International Classification:

H04B 11/00
H04R 1/02

US Classification:

381 86, 381389

Abstract:

A vehicle trunk woofer is a low frequency speaker disposed within the trunk of a vehicle so as to be separated from the vehicle passenger compartment by a dividing portion and a rear deck. The dividing portion may be a fixed element or a movable element, such as a fold down rear seat. The speaker mounted in the trunk may be mounted in an enclosure and may be mounted adjacent to the dividing portion, but is not mounted to the rear deck.

Appl. No.:

12/423572

George Nichols - Dover MA, US
Michael D. Rosen - Weston MA, US
Hal P. Greenberger - Natick MA, US

Assignee:

Bose Corporation - Framingham MA

International Classification:

H04R 1/02
H04R 7/00

US Classification:

381335, 181163

Abstract:

An apparatus for reducing baffle vibration includes a baffle that is subject to vibration. A first transducer that is seated in the baffle includes a first diaphragm that is acoustically coupled to a listening area in a vehicle and also acoustically coupled to a cavity in the vehicle. A first input signal applied to the first transducer causes the first diaphragm to move in a first direction, thereby generating an acoustic output. A second transducer is mechanically coupled to the first transducer. The second transducer includes a second diaphragm that is acoustically coupled to the first diaphragm and also acoustically coupled to the listening area. A second input signal applied to the second transducer causes the second diaphragm to move in a second direction that is substantially opposite to the first direction to reduce a vibration imparted to the baffle while substantially maintaining the acoustic output.

Abstract:

Preserving an audio signal in an audio system includes selecting a first audio signal from a plurality of audio signals. The first audio signal is applied to a first transducer. Mix a portion of the first audio signal with a second audio signal from the plurality of audio signals to provide a mixed audio signal. A gain of the first audio signal that is applied to the first transducer is decreased while a portion of the mixed audio signal is applied to a second transducer to preserve at least a portion of the first audio signal.
