Abstract

An audio system includes a housing that defines an acoustic enclosure, an acoustic driver supported by the housing and arranged to radiate acoustic energy from a front surface of the housing, an acoustic exit located in a rear surface of the housing, opposite the front surface. The acoustic exit has a shape that facilitates a grasping of the housing with a plurality of fingers and the thumb from a single human hand, such that at least one of the plurality of fingers and the thumb can be inserted into the exit while at least one of the plurality of fingers and the thumb of the same hand can rest on at one of the front surface or a top surface of the housing.

Claims

1. An audio system comprising:

a housing defining an acoustic enclosure;

an acoustic driver supported by the housing and arranged to radiate acoustic energy from a front surface of the housing; and

an acoustic exit located in a rear surface of the housing, opposite the front surface,

wherein the acoustic exit has a shape that facilitates a grasping of the housing with a plurality of fingers and the thumb from a single human hand, such that the plurality of fingers or the thumb can be inserted into the exit while the plurality of fingers or the thumb of the same hand can rest on the front surface of the housing.

2. The audio system of claim 1, wherein the acoustic exit is the exit of a port.

3. The audio system of claim 1, wherein the acoustic exit comprises a flared end.

4. The audio system of claim 1, wherein an inside surface of the acoustic exit comprises a textured surface, which facilitates gripping the inside surface of the acoustic exit with the plurality of fingers or the thumb from the human hand.

5. The audio system of claim 1, further comprising a user interface supported by the housing.

6. The audio system of claim 5, wherein the user interface comprises controls to operate audio system functions comprising at least one of audio volume, audio track selection, audio track skip, audio track stop, audio track pause, audio track rewind, audio track fast forward, and audio track play.

7. The audio system of claim 5, wherein the user interface comprises at least one control configured to be programmed to perform a specific function.

8. The audio system of claim 1, further comprising a display supported by the housing, the display configured to display at least one of information, graphics, and video images.

9. The audio system of claim 1, further comprising a power input terminal for connecting to an external power source.

10. The audio system of claim 1, further comprising an auxiliary input terminal configured to couple an external audio source to the audio system.

11. The audio system of claim 1, further comprising a textured grille applied to the front surface of the housing through which acoustic energy from the acoustic driver radiates.

12. The audio system of claim 1, further comprising a portable energy source supported by the housing for powering the acoustic driver.

13. The audio system of claim 12, wherein the portable energy source is removably mounted to the housing.

14. The audio system of claim 1, further comprising a waveguide located within the housing, the waveguide having a first end acoustically coupled to the acoustic enclosure and a second end that terminates at the acoustic exit.

15. The audio system of claim 14, wherein the waveguide comprising a first subsection that bends around a first axis and includes a first cross-sectional area with an aspect ratio that is substantially different from unity, a second subsection that bends around a second axis that is non-parallel to the first axis and includes a second cross-sectional area with an aspect ratio that is substantially different from unity, and a third subsection that acoustically couples the first subsection to the second subsection, the third subsection comprising a third cross-sectional area with an aspect ratio that varies between the first aspect ratio and the second aspect ratio.

16. The audio system of claim 14, wherein at least one of the first, second, and third cross-sectional areas each comprise a long dimension and a short dimension, and wherein the first and the second cross-sectional areas bend around an axis parallel to the long dimension of the respective first and second subsection.

17. The audio system of claim 14, wherein at least one of the first, second, and third cross-sectional areas comprise a rectangular shape.

18. The audio system of claim 14, wherein the third cross-sectional area of the waveguide comprises a long dimension and a short dimension and a first axis parallel to the long dimension and a second axis parallel to the short dimension are substantially not rotating when the aspect ratio of the third subsection varies.

19. The audio system of claim 14, wherein the first cross-sectional area and the second cross-sectional area are identical.

20. The audio system of claim 14, wherein the first cross-sectional area is smaller than the second cross-sectional area.

21. The audio system of claim 14, wherein the aspect ratio of the first cross-sectional area is different than the aspect ratio of the second cross-sectional area.

22. The audio system of claim 14, wherein the first axis is in a plane substantially perpendicular to the second axis.

23. The audio system of claim 14, wherein at least one of the first and second subsections bends around a cavity.

24. The audio system of claim 14, further comprising a docking cradle mechanically coupled to the housing such that the docking cradle is capable of being rotated horizontally between an open position and a closed position.
