Abstract

Speaker Cabinets are provided. In one embodiment, a speaker cabinet comprises: a core fabricated from a core material, the core material having an inner chamber defining an air cavity internal to the core; a baffle board having an internal side and an external side, wherein the internal side is mounted to the core at an opening to the air cavity; and a plurality of baffle board sonic coupling battens extending from the baffle board into the core material of the core.

Claims

1. A speaker cabinet, the speaker cabinet comprising:

a core fabricated from a core material, the core material having an inner chamber defining an air cavity internal to the core, the core material comprising a plurality of slots that form tunnels within the core material and which run from a front of the core towards a back of core;

an integrated one-piece element that includes a baffle board and a plurality of baffle board sonic coupling battens, the baffle board having an internal side and an external side, wherein the plurality of baffle board sonic coupling battens extend from the internal side of the baffle board;

wherein the each of the plurality of slots are positioned within the core to align with and receive a respective one of the plurality of baffle board sonic coupling battens;

wherein the internal side of the baffle board is mounted to the core at an opening to the air cavity.

2. The speaker cabinet of claim 1, wherein at least one of the plurality of baffle board sonic coupling battens only partially fills a respective slot of the plurality of slots into which it is inserted.

3. The speaker cabinet of claim 1, wherein at least one of the plurality of baffle board sonic coupling battens comprise a gradient in density from a first end to a second end.

4. The speaker cabinet of claim 1 further comprising a second plurality of slots that form tunnels within the core material and which run from a front of the core towards a back of core, wherein the second plurality of slots remain as open voids.

5. The speaker cabinet of claim 1, wherein the integrated one-piece element is a one-piece molded element.

6. The speaker cabinet of claim 1, further comprising:

an air cavity box positioned within the inner chamber of the core, wherein the air cavity is further defined within the air cavity box.

7. The speaker cabinet of claim 6, wherein the cavity box is rigidly secured to the plurality of baffle board sonic coupling battens by at least one fastener.

8. The speaker cabinet of claim 6, wherein the cavity box is in direct contact with at least one of the plurality of baffle board sonic coupling battens.

9. The speaker cabinet of claim 1, further comprising:

an external shell, wherein the core is housed within the external shell.

10. The speaker cabinet of claim 9, wherein the external shell comprises at least one of:

an extruded metal frame;

an aluminum material;

an acrylic material;

a wood material;

or

a medium density fiber (MDF) material.

11. The speaker cabinet of claim 1, wherein the core material comprises at least one of:

a structural foam material;

an open cell foam material;

an extruded polystyrene foam material;

a urethane foam material;

a polyurethane material;

or

a foamed styrol material.

12. The speaker cabinet of claim 1, further comprising a speaker mounted to the baffle board.

13. The speaker cabinet of claim 1, wherein the core comprises a plurality of sheets of foam material.

14. A method for acoustically tuning a speaker cabinet, the method comprising:

providing a core of a speaker cabinet, the core fabricated from a core material having an inner chamber defining an air cavity internal to the core, the core material comprising a plurality of slots that form tunnels within the core material and which run from a front of the core towards a back of core;

inserting a plurality of baffle board sonic coupling battens into the plurality of slots, wherein a first baffle board sonic coupling batten of the plurality of baffle board sonic coupling battens differs from a second baffle board sonic coupling batten of the plurality of baffle board sonic coupling battens in either size, shape, or density;

fastening a baffle board to the plurality of baffle board sonic coupling battens an opening to the air cavity.

15. The method of claim 14, further comprising:

installing an air cavity box positioned within the inner chamber of the core.

16. The method of claim 15, further comprising:

fastening the air cavity box to at least one of the plurality of baffle board sonic coupling battens using a fastener.

17. The method of claim 14, wherein at least one of the plurality of baffle board sonic coupling battens only partially fills a respective slot of the plurality of slots into which it is inserted.

18. The method of claim 14, wherein at least one of the plurality of baffle board sonic coupling battens comprise a gradient in density from a first end to a second end.

19. The method of claim 14, further comprising a second plurality of slots that form tunnels within the core material and which run from a front of the core towards a back of core, wherein the second plurality of slots remain as open voids.

20. The method of claim 14, further comprising mounting a speaker to the baffle board.
