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: The invention is directed to an improvement in mechanisms and techniques for accepting user input. An apparatus for accepting a user input is described comprising a display, and a plate and a control knob positioned over the display. A portion of the display is visible through the plate, and a portion of the control knob is optically transparent such that information displayed by the display is visible through the control knob. In some examples, the control knob functions as both a rotary input and as a push button input. The control knob may function as a push button input through a transfer of force through the plate to a pressure sensing switch associated with the plate. The control knob may function as a rotary control through drive gears, belts, or interaction with a light emitter and detector.

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 electroacoustical transducing system includes at least first and second line arrays detachably secured in electrical and mechanical coupling relationships. The assembly may be detachably secured to a base having an amplifier in electrical and mechanical coupling relationships.

Abstract: A loudspeaker enclosure is formed with fins that may be extended to support the enclosure on a surface and retracted into mating recesses to comprise a cosmetically appealing outer surface when the enclosure is suspended.
