Abstract: A loudspeaker system includes a subwoofer. The subwoofer includes a housing having a plurality of walls which together define an acoustic cavity. The plurality of walls includes a front wall, a rear wall, a top wall, a bottom wall, and a plurality of sidewalls extending between the top and bottom walls and between the front and rear walls. A first transducer mounted to the front wall of the housing. The first transducer includes a diaphragm having a major axis and a minor axis. The major axis has a fist end proximate the bottom wall and an opposite, second end proximate the top wall, such that the major axis is arranged vertical, relative to ground when the subwoofer is rested on its bottom wall. The top wall has a handle such that the loudspeaker can be carried with the major axis arranged vertical to ground.

Abstract: A waveguide assembly for a loudspeaker is provided. The waveguide assembly includes a plurality of panels and a plurality of trays, which together at least partially defines a waveguide. One or more of the panels are arranged to be movable relative to the trays to adjust a coverage pattern of the waveguide.

Abstract: A loudspeaker includes a cabinet, a coaxial transducer assembly, and a waveguide. The coaxial transducer assembly includes a first transducer and a second transducer that is coupled to the first transducer and arranged such that respective motion axes of the transducers are coaxial. The waveguide is coupled to the first transducer and configured to provide an acoustic impedance match between the first transducer and free air. The waveguide includes a first plurality of apertures that enables acoustic energy radiated from a first radiating surface of the second transducer to pass through the waveguide and merge with acoustic energy radiated by the first transducer. The first plurality of apertures extends through an expansion region of the waveguide.

Abstract: A ceiling tile loudspeaker includes an acoustic enclosure that defines an acoustic cavity. An electro-acoustic transducer is supported by the enclosure such that a first radiating surface of the electro-acoustic transducer radiates acoustic energy into the acoustic cavity and a second radiating surface of the electro-acoustic transducer radiates acoustic energy outward away from the acoustic enclosure. A first baffle is disposed within the acoustic cavity. The loudspeaker also includes a plurality of partitions, which, together with the first baffle, defines a plurality of ports that acoustically couple the acoustic cavity to an exterior of the enclosure. Each of the plurality of ports includes a first open end, a second open end, and a central axis extending therebetween. The ports are arranged such that their central axes lie in a plane that is substantially perpendicular to a motion axis of the electro-acoustic transducer.

Abstract: The present disclosure is directed to devices and systems for auto configuration of directional sound. The system comprises: a first and second portable bass loudspeaker, each arranged to radiate sound waves responsive to audio signals. Each portable bass loudspeaker has a sensor for determining whether the portable bass loudspeaker is in an aligned state or non-aligned state, wherein in the aligned state, the first portable bass loudspeaker is oriented in a generally parallel and opposite direction relative to the second portable bass loudspeaker. Each portable bass loudspeaker has an equalization device providing a first equalization setting for outputting audio in response to detection of the aligned state, and a second equalization setting for outputting audio in response to detection of the non-aligned state, wherein the first equalization setting is configured to generate a radiating output from the first and second portable bass loudspeaker in a cardioid pattern.

Abstract: A loudspeaker battery charging device comprises a three-position selector that establishes one of a first, second, or third charging mode for charging a battery of a loudspeaker. The first charging mode pertains to an off state of the loudspeaker. The second charging mode pertains to an on state of the loudspeaker. The third charging mode pertains to a fast charge state of the loudspeaker. A controller receives a signal from the three-position power switch indicating a selected charging mode of the first, second, or third charging mode. A switch circuit outputs a first power-supplying level in response to the first or second charging mode and outputs a second power-supplying level higher than the first power-supplying level in response to the third charging mode.
