Image Number 5 for United States Patent #5206465.

This invention relates to a loudspeaker having at least one sound collecting tubes attached to the rear of the speaker frame or the sound collecting tubes forming the speaker frame for collecting and directing sound waves emitted from the rear of the speaker diaphragm. The sound collecting tube is particularly useful for directing and boosting sound waves emitted from the rear of the speaker which is otherwise dissipated or absorbed by the loudspeaker housing material or insulation. In addition, conventional or specialized sound horns may be readily attached to the outlet end of the sound collecting tubes which can direct sound waves emitted by the speaker to any desired direction.
