Abstract (en)

[origin: WO9824268A1] Attempts to achieve fidelity of sound produced by speaker systems has led to often large, relatively complicated and expensive speaker cabinets, particularly for reproducing sound in the lower acoustic frequencies. A simple solution to the problem is a speaker assembly including a housing divided by a partition into a speaker chamber containing a speaker and a sound outlet chamber. The sound outlet chamber contains a sound outlet box remote from an opening in the partition connecting the speaker chamber to the sound outlet chamber. A sound outlet tube extends through the box and one wall of the housing. The interior of the box and at least a portion of the area around the box are filled with sand or another solid material for eliminating vibration or at least reducing vibration to a minimum.
