Patent number: 8073169Abstract: 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.Type: GrantFiled: October 31, 2007Date of Patent: December 6, 2011Assignee: Bose CorporationInventor: Michael D.

Patent number: 7983436Abstract: 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.Type: GrantFiled: April 14, 2009Date of Patent: July 19, 2011Assignee: Bose CorporationInventors: George Nichols, Michael D. Rosen, Hal P. Greenberger

Publication number: 20110142251Abstract: An instrument panel is structured to separate a main cabin of a vehicle from a volume behind the instrument panel. The instrument panel has multiple leak paths through which air can travel between the main cabin and the volume behind the instrument panel. An electroacoustical transducer is mounted in the instrument panel and operable to radiate low-frequency acoustic energy into the volume behind the instrument panel. The low-frequency energy radiated by the electroacoustical transducer in the volume behind the instrument panel propagates into the main cabin via the multiple leak paths.Type: ApplicationFiled: February 14, 2011Publication date: June 16, 2011Inventor: Michael D. Rosen

Patent number: 7940939Abstract: 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.Type: GrantFiled: December 24, 1996Date of Patent: May 10, 2011Inventors: Donald F. Hamilton, Michael D. Rosen

Publication number: 20100092006Abstract: A sound reproduction system in a vehicle includes an acoustic package including an electroacoustic transducer and a sound duct that carries the sound from the electroacoustic transducer. The sound duct carries the sound to an outlet at a location in the vehicle at which radiated sound efficiently drives selected audio modes of the vehicle.Type: ApplicationFiled: October 10, 2008Publication date: April 15, 2010Inventor: Michael D. Rosen

Patent number: 7551749Abstract: 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.Type: GrantFiled: November 30, 2004Date of Patent: June 23, 2009Assignee: Bose CorporationInventors: Michael D. Rosen, Richard Warren Little

Publication number: 20080101645Abstract: An apparatus for generating low frequency acoustic signals in a vehicle having an instrument panel is described. The apparatus includes a baffle that is located at least partially within the instrument panel. An electroacoustical transducer is mechanically coupled to the baffle. The electroacoustical transducer generates low frequency acoustic signals that radiate into a cavity within the instrument panel and leak into the passenger compartment of the vehicle.Type: ApplicationFiled: October 20, 2006Publication date: May 1, 2008Inventor: Michael D.

Patent number: 7305097Abstract: 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.Type: GrantFiled: February 14, 2003Date of Patent: December 4, 2007Assignee: Bose CorporationInventors: Michael D.

Patent number: 5170435Abstract: A loudspeaker system for radiation into the passenger compartment of a vehicle has one or more elongated acoustic waveguides to efficiently transfer sound pressure energy from a loudspeaker driver outside the compartment into the compartment. Preferred embodiments feature two elongated acoustic waveguides separated by the loudspeaker driver mounted on a hard baffle panel. One waveguide has an effective length of one quarter wavelength at the lowest frequency desired to be reproduced by the loudspeaker driver, and the other waveguide has an effective length three times that of the first waveguide. One or both waveguides may be folded upon itself. The loudspeaker system is driven through circuitry providing reduced system response at frequencies that may cause the deflection of the loudspeaker to exceed its maximum limits.Type: GrantFiled: March 2, 1992Date of Patent: December 8, 1992Assignee: Bose CorporationInventors: Michael D.
