Abstract

An automobile headrest includes a main body portion having a front surface arranged to support a back of a head of a user. The main body portion includes first and second speakers which are disposed within the main body portion, and a core that is configured to support the speakers. The automobile headrest also includes a pair of support rods that are connected to the core. The core is configured such that at least a portion of the speakers is disposed directly behind the head of the user when the back of the user's head rests against the front surface of the main body portion and is centered relative to the main body portion. The core defines a portion of one or more acoustic chambers for the first and second speakers.

First claim

What is claimed is:

1. An automobile headrest comprising:
A.) a main body portion comprising:
i.) first and second speakers disposed within the main body portion,
ii.) a core configured to support the speakers, and
iii.) a front cover formed as a one piece molded plastic part, the front cover defining a reaction plate that is arranged to support a back of a head of a user, wherein the reaction plate is configured such that at least a portion of the speakers is disposed behind the reaction plate and directly behind the head of the user when the back of the head of the user rests against the reaction plate and is centered relative to the main body portion; and

B.) a pair of support rods connected to the core,
wherein the core defines a portion of one or more acoustic chambers for the first and second speakers.

2. The automobile headrest of claim 1 , wherein the speakers are each configured to radiate acoustic energy along a respective central axis, and wherein the speakers are positioned such that their central axes do not cross a vertical plane at any point forward of the front surface of the main body portion, and
wherein the vertical plane bisects the headrest and extends through the front surface and an opposing, back surface of the main body portion.

3. The automobile headrest of claim 1 , wherein the speakers are arranged so as to direct acoustic energy in diverging directions, relative to each other, forward of the front surface.

4. The automobile headrest of claim 1 , wherein the speakers are positioned such that their central axes diverge at respective angles of about 5 degrees to about 60 degrees relative to a vertical plane,
wherein the vertical plane bisects the headrest and extends through the front surface and an opposing, back surface of the main body portion.

5. The automobile headrest of claim 4 , wherein the speakers are positioned such that their central axes diverge at respective angles of about 45 degrees relative to the vertical plane.

6. The automobile headrest of claim 1 , wherein the speakers are each configured to radiate acoustic energy along a respective central axis, and wherein the speakers are positioned such that their central axes are substantially parallel.

7. The automobile headrest of claim 1 , wherein the speakers are arranged adjacent each other between right and left sides of the main body portion, and wherein the main body portion has a width, measured between the left and right sides, of about 7.9 inches to about 11.4 inches.

8. The automobile headrest of claim 7 , wherein the main body portion has a width of 8.5 inches to 9.6 inches.

9. The automobile headrest of claim 1 , wherein the core is configured to support the speakers such that the speakers are at least partially disposed between a pair of longitudinal axes about which the support rods are arranged.

10. The automobile headrest of claim 7 , wherein the longitudinal axes of the support rods are spaced about 4.1 inches to about 6.0 inches apart.

11. The automobile headrest of claim 1 , wherein the core defines a plurality of ribs.

12. The automobile headrest of claim 1 , wherein the speakers are positioned symmetrically about a vertical plane that bisects the headrest and extends through the front surface and an opposing, back surface of the main body portion.

13. The automobile headrest of claim 1 , wherein the core is a one piece molded plastic part.

14. The automobile headrest of claim 1 , wherein the main body portion comprises a back cover connected to the core, and wherein the back cover and the core together define the one or more acoustic chambers.

15. The automobile headrest of claim 14 , wherein the one or more acoustic chambers comprise a plurality of acoustic chambers, and wherein the main body portion and the back cover together define the plurality of acoustic chambers.

16. The automobile headrest of claim 14 , wherein the back cover is welded to the core.

17. The automobile headrest of claim 1 , wherein the front cover further defines grille openings for the speakers.

18. The automobile headrest of claim 17 , wherein at least some of grille openings are formed in the reaction plate.

19. The automobile headrest of claim 1 , wherein the reaction plate is configured to minimize hyper rotation of the user's head and neck in the event of relatively sudden automobile acceleration.

20. The automobile headrest of claim 1 , wherein the core defines a pair of sockets each for receiving a distal end portion of one of the support rods.

21. The automobile headrest of claim 1 , wherein the front cover is formed of a material having a Rockwell hardness (R scale) of about 80 to about 121.

22. The automobile headrest of claim 1 , wherein the front cover comprises ribs to provide structural support for the reaction plate.

23. An automobile headrest comprising:
A.) a main body portion comprising:
i.) a core assembly comprising:
a.) first and second speakers disposed within the main body portion,
b.) a core configured to support the speakers,
c.) a back cover connected to the core, and
d.) a front cover formed as a one piece molded part, connected to the core, and defining grille openings and a reaction plate that is arranged to support a back of a head of a user, wherein the reaction plate is configured such that at least a portion of the speakers is disposed behind the reaction plate and directly behind the head of the user when the back of the head of the user rests against the reaction plate and is centered relative to the main body portion; and

B.) a pair of support rods connected to the core,
wherein the back cover and the core together define one or more acoustic chambers for the speakers.

24. The automobile headrest of claim 23 , wherein the back cover defines a contour of a back surface, opposite the front surface, of the main body portion.

25. The automobile headrest of claim 23 , wherein the front cover defines a contour of the front surface of the main body portion.

26. The automobile headrest of claim 23 , further comprising a cushion layer enveloping the core assembly, and a cover layer enveloping the cushion layer.

27. The automobile headrest of claim 26 , wherein the cushion layer includes a first region of relatively higher acoustic dampening, and a second region of relatively lower acoustic damping disposed in a region of the grille openings.

28. The automobile headrest of claim 23 , wherein the core defines a pair of sockets each for receiving a distal end portion of one of the support rods.

29. The automobile headrest of claim 23 , wherein the reaction plate is configured to minimize hyper rotation of the user's head and neck in the event of relatively sudden automobile acceleration.

30. The automobile headrest of claim 23 , wherein at least some of grille openings are formed in the reaction plate.

31. An automobile headrest comprising:
a main body portion comprising:
i.) first and second speakers disposed within the main body portion,
ii.) a unitary core having a front surface, wherein the core at least partially defines one or more acoustic chambers for the speakers, and wherein the core defines a pair of sockets each for receiving a distal end portion of a support rod, and
iii.) a front cover formed as a one piece molded plastic part and secured to the front surf
