Patent number: 11985459Abstract: A mounting system for mounting a loudspeaker to a substrate includes a mounting assembly having an elongated screw, a support member received on and movable along the screw, and a mounting arm rotatably connected to the support member and having a resting position and a working position. A guide housing receives the mounting assembly with the screw extending longitudinally therethrough and includes a wall structure with an open front side and a cap at a top portion of the wall structure. In the resting position, the support member is positioned along the screw at least partially received within the cap and the mounting arm is substantially contained within the wall structure. In the working position, the support member is positioned along the screw to be outside of the cap and the mounting arm is spring-biased away from the screw and extends outwardly through the front side of the wall structure.Type: GrantFiled: July 29, 2020Date of Patent: May 14, 2024Assignee: Harman International Industries, IncorporatedInventors: An Duc Nguyen, Christian Manuel Garcia, Larry Paul Brown, Chris N. Hagen

Patent number: 11564032Abstract: A speaker system is provided with a housing adapted to mount to a support. A driver is supported by the housing and arranged to project sound about a first axis extending at an offset angle relative to a longitudinal axis extending from the housing. A waveguide extends from the driver to define a cavity extending along the first axis. The waveguide includes a first segment formed at a first angle relative to the longitudinal axis, and a second segment formed at a second angle relative to the longitudinal axis, wherein the second segment is arranged opposite the first segment and the second angle is greater than the first angle to collectively provide an asymmetrical sound pattern in a first plane.Type: GrantFiled: April 30, 2021Date of Patent: January 24, 2023Assignee: HARMAN INTERNATIONAL INDUSTRIES, INCORPORATEDInventors: Christian Manuel Garcia, An Duc Nguyen, James Garrett

Patent number: 10433041Abstract: An outdoor loudspeaker that is weather resistant and includes environmental lighting is described. The lamp is mounted to a cap at the top of the loudspeaker. An audio driver is mounted below the lamp. A system outdoor loudspeakers is also described. The lighting circuitry and the audio circuitry is separate, e.g., separate conduits and wiring in the loudspeaker. The cap can include a light guide, e.g., a lens centrally mounted in the cap or an opaque cover to direct the light downwardly and outwardly. At least part of the loudspeaker can be mounted underground and, in the case of a sub-woofer, the entire chamber can be mounted below ground.Type: GrantFiled: April 24, 2017Date of Patent: October 1, 2019Assignee: Harman International Industries, IncorporatedInventors: James Garrett, Fred Tubis, An Duc Nguyen, Aaron L. Butters, Timothy Gladwin

Patent number: 10136201Abstract: A speaker assembly is provided with a housing, at least one transducer supported by the housing, and a controller. The controller is adapted to receive a first audio signal from a first audio source and a second audio signal from a second audio source. The controller is programmed to prioritize the first audio signal and the second audio signal based on a location of the housing relative to a charging station, and to provide the highest priority audio signal to the at least one transducer.Type: GrantFiled: October 27, 2016Date of Patent: November 20, 2018Assignee: Harman International Industries, IncorporatedInventors: Mark Fisher, An Duc Nguyen

Patent number: 7450729Abstract: One embodiment of a low-profile transducer includes a at least one fin perpendicularly mounted on a planar diaphragm, with a voice coil mounted onto the fin. The voice coil may reside in a strong uniform magnetic field. The locations at which the diaphragm is connected to a frame may be coplanar with a center of mass of the diaphragm. The three-dimensional structure of diaphragm and fins may be formed using origami techniques.Type: GrantFiled: April 9, 2004Date of Patent: November 11, 2008Assignee: Harman International Industries, IncorporatedInventors: An Duc Nguyen, Charles M.
