Abstract

The screen (13) is wound into a long rectangular housing (12) which is supported on feet. In the housing a chamber (16) is formed from a U-shaped metal sheet (22). In the chamber (16) is housed the winding bar (18) of the screen (13). A second chamber (17) is formed from a shaped metal sheet (24), this second chamber houses the two loudspeakers (20) which are mounted at the ends (14) of the screen housing. One side of the first chamber (16) forms a partition (26) between the two chambers (16, 17). The opposite side of the chamber (16) has a bent over edge (28) which forms with the top side (30) of the speaker housing (20) a slot. The projection screen (13) passes through the slot when it is wound and unwound.
