Abstract

A loudspeaker system includes a speaker enclosure having an opening in a front wall, and a speaker manifold mounted within the speaker enclosure and communicating with the opening. The speaker manifold includes a pair of substantially parallel side walls, a back wall, and top and bottom walls, defining a manifold chamber. The wall opposite the back wall is substantially open to define a manifold opening and to permit the communicating. The manifold opening is substantially in alignment with the front wall opening. A woofer is mounted on a first wall of the speaker manifold. An acoustic vent is mounted on a second wall of the manifold, such that the woofer and the acoustic vent face each other at one of about a 180 degree angle or about a 90 degree angle.

Claims (33)

1. A loudspeaker system, comprising:

a speaker enclosure having an opening in a front wall;

a speaker manifold mounted within said enclosure and communicating with said opening, said manifold comprising a pair of substantially parallel side walls, a back wall, and top and bottom walls, defining a manifold chamber, the wall opposite said back wall being substantially open, to define a manifold opening and to permit said communicating, said manifold opening being substantially in alignment with said front wall opening;

a first passive radiator mounted on a first wall of the speaker manifold;

a second passive radiator mounted on a second wall of the speaker manifold, such that the first acoustic vent faces the second acoustic at about a 180 degree angle; and

a woofer mounted on a third wall of the speaker manifold and facing the front wall opening,

wherein the woofer is disposed at about a 90 degree angle relative to the first and second acoustic vents.

2. The loudspeaker system as recited in claim 1 , wherein a surround of the first passive radiator is adjacent to the first wall of the speaker manifold, a surround of the second passive radiator is adjacent to the second wall of the speaker manifold, and a surround of the woofer is adjacent to the third wall of the speaker manifold.

3. The loudspeaker system as recited in claim 1 , wherein a surround of the woofer is partially covered by the speaker enclosure.

4. The loudspeaker system as recited in claim 1 , wherein the speaker enclosure further includes a power amplifier.

5. The loudspeaker system as recited in claim 1 , wherein a surface of at least one of the passive radiators is oval shaped.

6. The loudspeaker system as recited in claim 1 , wherein the speaker enclosure is hollow.

7. A loudspeaker system, comprising:

a speaker enclosure having an opening in a front wall;

a speaker manifold mounted within said enclosure and communicating with said opening, said manifold comprising a pair of substantially parallel side walls, a back wall, and top and bottom walls, defining a manifold chamber, the wall opposite said back wall being substantially open, to define a manifold opening and to permit said communicating, said manifold opening being substantially in alignment with said front wall opening;

a first air port mounted on a first wall of the speaker manifold;

a second air port mounted on a second wall of the speaker manifold, such that the first air port faces the second air port at about a 180 degree angle; and

a woofer mounted on a third wall of the speaker manifold and facing the front wall opening,

wherein the woofer is disposed at about a 90 degree angle relative to the first and second air ports.

8. The loudspeaker system as recited in claim 7 , wherein a surround of the woofer is partially covered by the speaker enclosure.

9. The loudspeaker system as recited in claim 7 , wherein the speaker enclosure further includes a power amplifier.

10. The loudspeaker system as recited in claim 7 , wherein the speaker enclosure is hollow.

11. A loudspeaker system, comprising:

a speaker enclosure having an opening in a front wall;

a speaker manifold mounted within said enclosure and communicating with said opening, said manifold comprising a pair of substantially parallel side walls, a back wall, and top and bottom walls, defining a manifold chamber, the wall opposite said back wall being substantially open, to define a manifold opening and to permit said communicating, said manifold opening being substantially in alignment with said front wall opening;

a passive radiator mounted on a first wall of the speaker manifold;

an air port mounted on a second wall of the speaker manifold, such that the passive radiator faces the air port at about a 180 degree angle; and

a woofer mounted on a third wall of the speaker manifold and facing the front wall opening,

wherein the woofer is disposed at about a 90 degree angle relative to the passive radiator and the air port.

12. The loudspeaker system as recited in claim 11 , wherein a surround of the woofer is partially covered by the speaker enclosure.

13. The loudspeaker system as recited in claim 11 , wherein the speaker enclosure further includes a power amplifier.

14. The loudspeaker system as recited in claim 11 , wherein a surface of the passive radiator is oval shaped.

15. The loudspeaker system as recited in claim 11 , wherein the speaker enclosure is hollow.
