Abstract: A modular horn type loudspeaker and a modular horn array formed of modular loudspeakers. An acoustic horn includes a first acoustic module. The first acoustic module includes a first acoustic driver and a first acoustic duct, for conducting acoustic energy from the first acoustic driver. The first acoustic duct has a first opening through which acoustic energy is radiated. The first acoustic duct is characterized by a first centerline. A second acoustic module includes a second acoustic driver and a second acoustic duct, for conducting acoustic energy from the acoustic driver. The second acoustic duct has a second opening through which acoustic energy is radiated. The second acoustic duct is characterized by a second centerline.

Abstract: A stand that is adapted to support an upper loudspeaker cabinet relative to a lower loudspeaker cabinet. The stand has a first structure that is constructed and arranged to be directly coupled to a first portion of the lower loudspeaker cabinet in a stand stowed position wherein the stand is stowed on or in the lower loudspeaker cabinet, and a second structure that is constructed and arranged to be directly coupled to a second portion of the lower loudspeaker cabinet in a stand deployed position wherein the stand is supported by and extends above the lower loudspeaker cabinet. The stand is further constructed and arranged to support the upper loudspeaker cabinet when the stand is in the deployed position.

Abstract: A directional acoustic device with an acoustic source or an acoustic receiver and a conduit to which the acoustic source or acoustic receiver is acoustically coupled and within which acoustic energy travels in a propagation direction from the acoustic source or to the acoustic receiver. The conduit has a radiating portion that has a radiating surface with leak openings that define controlled leaks through which acoustic energy radiated from the source into the conduit can leak to the outside environment or through which acoustic energy in the outside environment can leak into the conduit. The radiating surface has a thin sheet with openings through the sheet, and a cover material with a greater acoustic resistance than an acoustic resistance of an opening. The cover material covers at least parts of at least some of the openings, to define controlled acoustic leaks into or out of the conduit.

Abstract: A loudspeaker includes a plurality of electro-acoustic drivers that are configured to be positioned so that an axis running through an acoustic center of the drivers is one of a substantially straight line, J-shape, reverse J-shape, and C-shape. The loudspeaker also includes at least one sensor to detect a configuration of the plurality of electro-acoustic drivers, and a processing device configured to automatically adjust one or more of an equalization and a gain applied to an audio signal output through the electro-acoustic drivers based on the detected configuration.

Abstract: A loudspeaker system includes a first flexible panel, a first line array of electro-acoustic drivers, and at least one mechanically adjustable point. The first line array of electro-acoustic drivers are mounted on the first flexible panel and linked to each other by flexible joints in the first flexible panel. The at least one mechanically adjustable point enables articulation of the first flexible panel at the flexible joints to produce one or more of a substantially straight and an arcuate configuration of the first line array of electro-acoustic drivers.

Abstract: A compact and portable loudspeaker system operable in two configurations includes a driver array and a base unit having a bass enclosure and a dock. In an extended configuration, the driver array is supported by one or more extension legs between three to eight feet above the base unit where one of the extension legs is held by the dock. The base unit may be placed on a floor of a small to medium venue with the mid-to-high range driver array elevated near or above the elevation of an audience in the venue. In a compact configuration, the driver array is directly supported by the dock and the base unit and driver array may be placed on a table or desk in a classroom, conference room, or other such small to medium venue. The portable loudspeaker system may be transported in the compact configuration.

Abstract: Among other things, a receptacle supports an electronic device; support legs connected to the receptacle are movable in a common plane between a first, retracted position and a second, extended position; and a coupling translates movement of one of the support legs between the positions to corresponding movement of at least another one of the support legs.

Abstract: A line array loudspeaker, including a first plurality of acoustic drivers each acoustic driver comprising an axis, the first plurality of acoustic drivers arranged so that the axes of first plurality of acoustic drivers are coplanar in a first plane and so that a straight line intersects each axis at a same position on each of the first plurality of acoustic drivers, and a second plurality of acoustic drivers each acoustic driver comprising an axis, the second plurality of acoustic drivers arranged so that the axes of second plurality of acoustic drivers are coplanar in a second plane and so that the straight line intersects each axis at a same position on each of the second plurality of acoustic drivers, in which the first plurality and the second plurality arranged so that the first plane intersects with the second plane along a straight intersection line.
