Abstract: In accordance with the invention is disclosed a portable speaker of exceptionally low bulk yet very good performance which incorporates a non-homogeneous enclosure shape consisting of two main parts, one shallow box-shaped housing section and one cylindrical housing section, and incorporating retractable legs for support of the housing on the ground or table on which it is placed during its operation. A much larger loudspeaker than would be otherwise possible can then be used in an enclosure of very small bulk. The box-shaped housing section is dedicated to housing only the frame/basket and concentric diaphragm of the speaker, which, together generally comprises only half the speakers total length where the other half of the speakers length, the magnet assembly, is enclosed by the cylindrical section.
