  • Patent number: 5979591
    Abstract: A portable loudspeaker enclosure is made of a collapsible shell of a fabric material, e.g., canvas, having top, bottom, left, right, and back walls. These walls each are each formed of a sandwich of fabric layers and an acoustic insulation layer, such as foamed plastic or glass fiber, the insulation layer being disposed to the inside of the shell. The fabric at each wall forms a pouch co-extensive with the wall. A rigid speaker frame serves as a front wall for the enclosure and is fitted into the front of the enclosure. The frame extends within the shell towards the back wall to a point behind the loudspeaker, i.e., about one-third of the front-to-back dimension. For each wall there is a rigid batt or insert that is dimensioned to fit removably into the pouch. The batts create a rigid cavity behind the loudspeaker. The portable enclosure can have a front cover that removably covers the front wall of the enclosure, i.e., for storage and transit.
