Abstract:

A portable speaker device comprising a front mounting plate ( 1 ) having two openings ( 1 a, 1 b) for sound transmission, two loudspeakers ( 3 a, 3 b) 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 ( 7 a, 7 b). These bodies are each formed by a plurality of separate ring-shaped enclosure members ( 11 a₁- 11 a₅ ; 11 b_1'- 11 b₅) axially movable with regard to each other. The members of each enclosure body have a front member ( 11 a_1' ; 11 b₁) secured to the front mounting plate in surrounding relation to one of the loudspeakers and a rear member ( 11 a₅ ; 11 b₅) 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 ( 13 a; 13 b).
