ABSTRACT:
A modular loudspeaker comprises a first module including a first loudspeaker unit (1) for reproducing a low-frequency audio signal and provided with at least two flat diaphragms (4, 5) and a second module including a second loudspeaker unit (2) for reproducing a high-frequency audio signal by means of a loudspeaker (8). The first and second loudspeaker units are constructed either to be mechanically detached from one another or to have connecting means whereby they can be rigidly mechanically connected to one another in a manner that will permit relatively easy mechanical detachment of the units from one another. Connecting means (10 or 11) allows the loudspeaker units to be electrically connected to one another and comprise interengageable parts that can be disengaged to disconnect the units. Another loudspeaker arrangement, which need not be of a modular construction, comprises a first loudspeaker unit (60) having at least one flat-diaphragm loudspeaker (61) and a second loudspeaker unit (62) which is pivotable about two orthogonal axes (65, 66).
