Patent number: 11450302Abstract: A loudspeaker is provided with a motor assembly having at least one planar coil and first and second magnets magnetized in a magnetized direction perpendicular to direction of coil movement and perpendicular to a central axis of radiation of the loudspeaker. Ferrofluid is disposed between a diaphragm and the first and second magnets. Third and fourth magnets are disposed outside the first and second magnets and are magnetized in a direction parallel to the direction of coil movement and perpendicular to the magnetized direction of the first and second speakers.Type: GrantFiled: March 7, 2019Date of Patent: September 20, 2022Assignee: HARMAN INTERNATIONAL INDUSTRIES, INCORPORATEDInventors: Guenther Weber, Gilles Milot, Marc-Olivier Chauveau, Ludovic Fournier, Armin Prommersberger

Patent number: 11218811Abstract: A loudspeaker and method of operating a loudspeaker are provided. The loudspeaker has a motor assembly with at least one planar coil. First and second magnets are magnetized in a magnetized direction perpendicular to a direction of coil movement and perpendicular to a central axis of radiation of the loudspeaker. The central axis of radiation is generally parallel to a direction of coil movement and parallel to the plane of the planar coil. The first and second magnets each have upper and lower large surface faces separated by a narrowest dimension. The first and second magnets are magnetized across the narrowest dimension in first and second magnetized directions being opposite.Type: GrantFiled: March 7, 2018Date of Patent: January 4, 2022Assignee: HARMAN INTERNATIONAL INDUSTRIES, INCORPORATEDInventors: Gilles Milot, Marc-Olivier Chauveau, Ludovic Fournier, Guenther Weber, Armin Prommersberger

Patent number: 10869131Abstract: An example magnet assembly for a loudspeaker includes a first permanent magnet with a cuboid shape, the first magnet encompassing a central opening, and a second permanent magnet with a cuboid shape, the second magnet positioned coaxially within the opening of the first magnet and forming a rectangular-ring shaped first gap therebetween, the first and second magnets being axially poled in opposed directions. The assembly further includes a soft-magnetic base plate connected across one side of the first and second magnets, a soft-magnetic first pole piece having a first face and positioned on the first magnet, and a soft-magnetic second pole piece having a second face and positioned on the second magnet. The first pole piece and the second pole piece form a rectangular-ring shaped second gap between the first and second faces such that magnetic flux is focused in the second gap.Type: GrantFiled: June 21, 2017Date of Patent: December 15, 2020Inventors: Guenther Weber, Marc-Olivier Chauveau, Armin Prommersberger

Patent number: 9888305Abstract: A speaker system is provided with a docking station and a removable housing that is mounted to the docking station. The speaker system also includes a receiver, a transducer and a processor that are supported by the removable housing. The receiver receives an audio signal from a mobile media device. The processor communicates with the receiver and is programmed to determine a location of the removable housing relative to the docking station, separate the audio signal into channels and provide at least one channel to the transducer based on the location.Type: GrantFiled: November 11, 2016Date of Patent: February 6, 2018Assignee: Harman Becker Automotive Systems GmbHInventors: Armin Prommersberger, Matthias von Saint-George
