  • Patent number: 10645484
    Abstract: A loudspeaker cabinet comprised of interlocking panels which may be assembled using external compressive forces and internal tensile forces is described. The panels may include corresponding tongue and groove elements that aid in the interconnection of the panels, and which may be at least partially swaged together. Internal tension members, such as tension rods, may run the length of the cabinet, up and down, and front to back, to keep panels of the cabinet under constant tension. An example cabinet body having six sides that sits above an integrated foot or shelf is constructed out of three interlocking panels. The present system and method may be used to create an inherently rigid cabinet that minimizes the movability of its constituent parts to avoid parasitic vibrations that interfere with the original sound waves emanating from the membrane of the driver of the loudspeaker.
