Marc-Olivier CHAUVEAU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240236548
    Abstract: Disclosed are a vehicle having a device for reproducing sound and a vehicle center console. The vehicle includes a device for reproducing sound by loudspeakers, including a single enclosure being installed in the center console of the vehicle. The enclosure includes two opposite ends and, internally, a pair of loudspeakers. The two loudspeakers are arranged face to face or back to back at the two opposite ends of the enclosure. The device for reproducing sound is installed in the front median space between the driver seat and the front passenger seat, and the two front side walls of the passenger compartment do not include a sound reproduction element for the low-frequency spectrum.

  • Patent number: 11450302
    Abstract: 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.

  • Patent number: 11218811
    Abstract: 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.

  • Patent number: 10869131
    Abstract: 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.
