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;

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;

wherein each of the plurality of baffle board sonic coupling battens extend into sides of the core laterally at least partially around the air cavity.

2. The speaker cabinet of claim 1, wherein one or more of the plurality of baffle board sonic coupling battens extend into a respective slot formed within the core material of the core.

3. The speaker cabinet of claim 1,

wherein the plurality of baffle board sonic coupling battens includes a first baffle board sonic coupling batten that extends from the baffle board into the core to a first region and a second baffle board sonic coupling batten that extends from the baffle board into the core to a second region on an opposing side of the air cavity from the first region.

4. The speaker cabinet of claim 3,

wherein the plurality of baffle board sonic coupling battens are configured to transmit sonic energy towards a back of the air cavity.

5. 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.

6. The speaker cabinet of claim 1,

wherein the plurality of baffle board sonic coupling battens are arranged to laterally extend around a circumference of the air cavity to transmit sonic energy around the circumference of the air cavity.

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

8. 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.

9. 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 coupled to the baffle board to an opposing second end.

10. The speaker cabinet of claim 1, wherein at least one of the plurality of baffle board sonic coupling battens extend from the baffle board into the core at an angle not perpendicular with respect to the internal side of the baffle board.

11. The speaker cabinet of claim 1, wherein at least one of the plurality of baffle board sonic coupling battens extend from the baffle board to a region of the core past a back of the air cavity.

12. An audio electronics cabinet, the cabinet comprising:

a core fabricated from a first material;

an air cavity box fabricated from a second material and positioned internal to the core, the air cavity box having at least a first internal surface that defines an internal air cavity;

a plurality of baffle board sonic coupling battens interfacing with an exterior of the air cavity box, the plurality of baffle board sonic coupling battens embedded within the core material, the air cavity box comprising at least a first opening to the air cavity; and

a baffle board mounted to the core over the first opening to the air cavity box, wherein the plurality of baffle board sonic coupling battens extend from the baffle board;

wherein the plurality of baffle board sonic coupling battens includes a first baffle board sonic coupling batten that extends from the baffle board into the core to a first region and a second baffle board sonic coupling batten that extends from the baffle board into the core to a second region on an opposing side of the air cavity from the first region.

13. The cabinet of claim 12, wherein one or more of the plurality of baffle board sonic coupling battens are fastened to the baffle board by a fastener.

14. The cabinet of claim 12, wherein each of the plurality of baffle board sonic coupling battens extend into sides of the core laterally at least partially around the first opening to the air cavity.

15. The cabinet of claim 12, wherein the first 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.

16. The cabinet of claim 12, wherein the plurality of baffle board sonic coupling battens each comprise at least one of:

a wood material;

a dense composite material.

17. The cabinet of claim 12, wherein

the plurality of baffle board sonic coupling battens are configured to transmit sonic energy towards a back of the air cavity.

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

19. A method for producing sound from a speaker, the method comprising:

generating acoustical energy with a speaker attached to a baffle board, the speaker housed within a cavity of a structural core comprising a core material; and

transmitting the acoustical energy into the core material using a plurality of baffle board sonic coupling battens extending from an internal side of the baffle board into the core material of the core;

wherein the plurality of baffle board sonic coupling battens includes at least a first baffle board sonic coupling batten that extends from the baffle board into the structural core to a first region and a at least a second baffle board sonic coupling batten that extends from the baffle board into the structural core to a second region on an opposing side of the cavity from the first region.

20. The method of claim 19, wherein the plurality of baffle board sonic coupling battens transmit sonic energy around the cavity and towards a back of the cavity.
