Speaker enclosure
First Claim
1. A loudspeaker system comprising:
- a loudspeaker having front and rear surfaces for radiating sound waves;
an enclosure for said loudspeaker including a first wall having a first aperture therethrough for receiving the loudspeaker such that said front surface is external to said enclosure and said rear surface is internal to said enclosure, said enclosure having a second aperture therethrough;
an at least partially inclined partition disposed within said enclosure defining a folded acoustic path between said rear surface of said loudspeaker and said second aperture, said folded acoustic path having a region of decreased cross-sectional area proximate to said second aperture.

Abstract
A loudspeaker enclosure accommodates at least one speaker in the front wall of the enclosure. The interior of the enclosure is divided into two smaller chambers by means of a partition inclined with respect to the front and rear walls. One such chamber is adjacent to the speaker, while the second or rear chamber is separated from the front chamber by the partition. Below the speaker is a vent or port in communication with the rear chamber. Sound waves emanating from the rear of the speaker are reflected by the inclined partition and reflected upwardly toward the top of the speaker enclosure. The partition does not extend to the top wall of the enclosure, thereby allowing sound waves to reflect off of the top wall and enter the rear chamber. The sound waves then exit the enclosure through the port below the speaker. The rear waves are thus delayed with respect to the front waves from the speaker to achieve the desired tuning of the speaker system. Furthermore, the arrangement of the interior partition causes the rear waves to be compressed at two locations thereby increasing the effective delay and further improving low frequency response.

12. An enclosure for a loudspeaker comprising:
-
a front wall having a first aperture therethrough for receiving the loudspeaker; a top wall, a bottom wall, a rear wall and a pair of side walls coupled to said front wall to form a generally box-like structure enclosing an interior volume, said box-like structure having a second aperture therethrough; an at least partially inclined partition abutting said front wall below said first aperture and extending between said side walls, said partition disposed so as to define a folded acoustic path within said interior volume between said first and second apertures, said folded acoustic path having a region of decreased cross-sectional area proximate to said second aperture.
