Abstract
An improved loudspeaker box, characterized by having a cover of minimum dimensions to house inside a frame in whose central opening the loudspeaker is arranged, so that said frame can rotate around pivots, invisible externally, located close to its internal upper edge, so that the acoustic vibrations of the loudspeaker can be transmitted to the outside air. The speaker frame has lateral fins that guide its movement inside the lid. (Machine-translation by Google Translate, not legally binding)
