<p>A portable speaker device comprising a front mounting plate (1) having two openings (la, lb) for sound transmission, two loudspeakers (3a, 3b) each fixedly secured to the front mounting plate for broadcasting through one of the openings, a rear mounting plate extending parallel to the front mounting plate (5), and two enclosure bodies (7a, 7b). These bodies are each formed by a plurality of separate ring-shaped enclosure members (11a1 - 11a5; 11b1, - 11b5) axially movable with regard to each other. The members of each enclosure body have a front member (11a1,; 11b1) secured to the front mounting plate in surrounding relation to one of the loudspeakers and a rear member (11a5; 11b5) secured to the rear mounting plate. In a non-operational position of the speaker device, the mounting plates extend closely to each other, whereby the enclosure bodies have a collapsed shape and the device is very compact. In an operational position of the speaker device the mounting plates extend at a distant to each other, wherein the enclosure bodies have an extended shape and form sound cabinets (13a; 13b) .</p> |
