<P>PROBLEM TO BE SOLVED: To provide a loudspeaker unit particularly for "home cinema". <P>SOLUTION: The loudspeaker unit comprises, in combination, a pistonic loudspeaker and a resonant panel loudspeaker arranged such that a resonant panel is movable, for example by rotation, with respect to the pistonic loudspeaker. The resonant panel can be moved with respect to the pistonic loudspeaker between a first position in which the resonant panel covers the pistonic loudspeaker, and a second position in which the piston type loudspeaker is uncovered from the resonant panel. The resonant panel can be moved by means of a motor, for example by remote control. A loudspeaker assembly comprising a resonant panel loudspeaker, a support to which the resonant panel loudspeaker is attached, and a motor by which the resonant panel is movable with respect to the support, is also disclosed. The assembly can form part of the unit. The unit or assembly can be attached to a wall or other boundary, for example in a recess. <P>COPYRIGHT: (C)2004,JPO |
