Zusammenfassung:	A portable loudspeaker (10) resembling a double CD case, comprises left- and right-hand lids (12, 14) pivotally coupled about parallel axes AA and BB to side walling (16). The side walling (16) forms an open box-like enclosure, with the left- and right-hand lids (12, 14) acting as the top and bottom surfaces to complete the enclosure when covering the opening at either end of the side walling (16). Each lid comprises a sound generating unit in the form of a distributed mode acoustic radiator (20). By adopting the shape of a double CD-case, the loudspeaker is more readily accepted as a portable loudspeacker by users of personal CD players. Similar considerations apply to portable loudspeakers shaped like single CD cases, audio-tape cassette cases and mini-disc cases.
