Abstract

A stereophonic speaker headrest for motor vehicles includes a rigid interior shell and a padded cover. The rigid interior shell is generally hollow with a pair of opposed side wing members having speaker attachment structure therein for holding a speaker in each wing. The hollow portion of the rigid interior shell adjacent the speaker attachment structure forms an acoustic chamber. The padded cover provides substantial padding over the front and rear surfaces of the rigid interior shell, including the area in front of the speakers.

Claims

1. A stereo speaker headrest for a vehicle comprising

a rigid interior shell having a pair of side wing members, each having a speaker opening, and a substantially arcuate central front surface,

speaker attachment means for holding a pair of speakers such that each speaker is adjacent a different one of said speaker openings and such that the speakers are displaced laterally from one another, each wing member containing a speaker attachment means,

an acoustical chamber defined by the walls of each wing member,

a padded cover for substantially covering at least the front and rear surfaces of said rigid interior shell, and

attachment means for attaching said headrest to a vehicle seat.

2. The headrest of claim 1 wherein said interior shell has a substantially arcuate rear surface, said rear surface having a substantially larger radius of curvature than said front surface.

3. The headrest of claim 2 wherein said wing members have substantially flat front surfaces having an included angle therebetween of about 80°

to about 100°

.

4. The headrest of claim 1 wherein said interior shell has front, back, top and bottom walls forming a substantially enclosed cavity.

5. The headrest of claim 2 wherein said interior shell is substantially symmetrical about a vertical plane passed through the front and back at the midpoint of the headrest and is substantially symmetrical about a horizontal plane passed through the front and back at the midpoint of the headrest.

6. The headrest of claim 5 wherein said headrest shell is composed of four component parts.

7. The headrest of claim 6 wherein said two of said components are identical in structure and the remaining two are identical in structure, being substantially a mirror image of the structure of the first pair.

8. The headrest of claim 7 wherein one component from each pair of identical components are joined to form one-half of the headrest and the remaining two components are joined to form the other one-half of the headrest.

9. The headrest of claim 8 wherein the different components joined together have web members therein which combine with the walls of the components to define an acoustic chamber.

10. The headrest of claim 4 wherein said interior shell has at least one interior web member abutting the front, back, bottom and top walls to separate said interior shell into two enclosed, acoustic chambers.
