Patent number: 10848861Abstract: A loudspeaker assembly for a vehicle includes an enclosure arranged to be positioned outside of a passenger compartment of the vehicle adjacent a first vehicle body panel. The enclosure has a front side, a rear side, a top portion and a substantially enclosed bottom portion, where the top portion includes an outer wall structure. A loudspeaker is mounted in the enclosure and configured to generate an acoustic signal to be radiated into the passenger compartment through an opening in a second vehicle body panel. The enclosure may include a plurality of ribs extending between the loudspeaker and the outer wall structure. A barrier may be disposed within the top portion inward of the outer wall structure and substantially surrounding the loudspeaker. The ribs and the barrier damp high frequencies to reduce propagation of high-frequency noise toward the passenger compartment.Type: GrantFiled: April 16, 2019Date of Patent: November 24, 2020Assignee: Harman Becker Automotive Systems GmbHInventors: Joerg Prokisch, Michael Schuster, Andreas Pfeffer

Patent number: 8139783Abstract: A speaker assembly arrangement for a vehicle is provided that includes a speaker unit including a speaker cabinet defining a first volume and a body part of a vehicle including a hollow member defining a second volume. The speaker cabinet is acoustically coupled to the hollow member by a press-fit coupling having a press-fit direction and mounted on the body part by at least one fastener having a fastening direction substantially perpendicular to the press-fit direction. The body part comprises a first guide arranged and configured to slidably engage with a second guide arranged on the speaker cabinet so that force on the speaker cabinet in the fastening direction is at least in part redirected to the press-fit direction by the slidable engagement of the first guide and the second guide.Type: GrantFiled: May 11, 2009Date of Patent: March 20, 2012Assignee: Harman Becker Automotive Systems GmbHInventors: Michael Schuster, Joerg Prokisch
