Casing for one or more loudspeakers, comprises several chambers, each with sound radiation apertures which oppose each other

摘要

The loudspeaker casing has several chambers (1,2), each with sound radiation aperture (3). At least two chambers are so interconnected that one chamber surrounds the diaphragm in front side. The second chamber surrounds the diaphragm rear side to form a sound guideway. Preferably the sound radiation apertures of the chambers oppose each other. The chamber should be so small that the natural resonance of the loudspeaker is reduced.
