Abstract

Various aspects include audio eyeglasses with through-hinge wiring configurations. In particular aspects, audio eyeglasses include: a frame for resting on a head of a user, the frame comprising: a lens region; a pair of arms extending from the lens region; and a hinge coupling the lens region and one of the pair of arms, the hinge comprising: a body; a friction element coupled to the body for damping the movement of the arm relative to the lens region; and a cavity within the body, the cavity sized to accommodate a cable extending therethrough, the hinge permitting movement of the arm relative to the lens region; and an electro-acoustic transducer at least partially housed in the frame and comprising a sound-radiating surface for providing an audio output.

First claim

We claim:

1. Audio eyeglasses comprising:
a frame for resting on a head of a user, the frame comprising:
a lens region;
a pair of arms extending from the lens region; and
a hinge coupling the lens region and one of the pair of arms, the hinge comprising:
a body;
a friction element coupled to the body for damping the movement of the arm relative to the lens region; and
a cavity within the body, the cavity comprising a first opening to a pathway in the lens region, and a second opening to an additional pathway in the arm, wherein the first opening and the second opening are wider than the cable, and the first opening is wider than the second opening, wherein an offset between the first and second openings causes a cable extending through the cavity to exhibit at least one bend between the first and second openings, the hinge permitting movement of the arm relative to the lens region; and

an electro-acoustic transducer at least partially housed in the frame and comprising a sound-radiating surface for providing an audio output.

2. The audio eyeglasses of claim 1 , wherein the hinge has a contoured edge at an interface with the arm and an additional contoured edge at a surface thereof adjacent the second opening.

3. The audio eyeglasses of claim 1 , wherein the hinge is fixed within a slot in the lens region.

4. The audio eyeglasses of claim 1 , further comprising a set of pins coupling the hinge to the arm.

5. The audio eyeglasses of claim 4 , wherein the set of pins comprises an upper pin and a lower pin each extending through a respective mating slot in the hinge, wherein neither the upper pin nor the lower pin extends through the cavity to interfere with the cable.

6. The audio eyeglasses of claim 1 , wherein the friction element comprises at least one of a silicone damper or a spring-loaded device.

7. The audio eyeglasses of claim 1 , wherein the friction element is coupled with an outer surface of the body.

8. The audio eyeglasses of claim 1 , wherein the friction element extends into a slot or a mating groove in the body.

9. The audio eyeglasses of claim 1 , further comprising an additional hinge coupling the lens region and the second one of the pair of arms, the additional hinge comprising:
a body;
a friction element coupled to the body for damping the movement of the arm relative to the lens region; and
a cavity within the body, the cavity sized to accommodate the cable extending therethrough.

10. The audio eyeglasses of claim 1 , wherein the hinge substantially obstructs the cable from view when the audio eyeglasses are in an open position, and completely obstructs the cable from view when the audio eyeglasses are in a closed position.

11. The audio eyeglasses of claim 1 , wherein the cable comprises a flexible printed circuit (FPC).

12. The audio eyeglasses of claim 1 , further comprising:
a controller connected with the electro-acoustic transducer; and
an interface connected with the controller.

13. The audio eyeglasses of claim 12 , wherein the interface comprises a button or a capacitive touch interface.

14. The audio eyeglasses of claim 12 , wherein the interface comprises a compressible interface that allows a user to squeeze one or more sections of the arms to initiate a user interface command.

15. The audio eyeglasses of claim 12 , further comprising an inertial measurement unit (IMU) connected with the controller for enabling at least one of location-based control functions or orientation-based control functions.

16. Audio eyeglasses comprising:
a frame for resting on a head of a user, the frame comprising:
a lens region;
a pair of arms extending from the lens region; and
a hinge coupling the lens region and one of the pair of arms, the hinge comprising:
a body;
a friction element coupled to the body for damping the movement of the arm relative to the lens region; and
a cavity within the body, the cavity sized to accommodate a cable extending therethrough, wherein the cavity has a first opening to a pathway in the lens region, and a second opening to an additional pathway in the arm, wherein the first opening and the second opening are wider than the cable, and the first opening is wider than the second opening, and wherein the hinge permits movement of the arm relative to the lens region; and

an electro-acoustic transducer at least partially housed in the frame and comprising a sound-radiating surface for providing an audio output.

17. The audio eyeglasses of claim 16 , wherein the first opening has a width that is approximately 3-5 times a width of the second opening.

18. Audio eyeglasses comprising:
a frame for resting on a head of a user, the frame comprising:
a lens region;
a pair of arms extending from the lens region; and
a hinge coupling the lens region and one of the pair of arms, the hinge comprising:
a body;
a friction element coupled to the body for damping the movement of the arm relative to the lens region; and
a cavity within the body, the cavity sized to accommodate a cable extending therethrough, the hinge permitting movement of the arm relative to the lens region, wherein the cavity comprises a first opening to a pathway in the lens region, and a second opening to an additional pathway in the arm, wherein the first opening is wider than the second opening; and

an electro-acoustic transducer at least partially housed in the frame and comprising a sound-radiating surface for providing an audio output, wherein the electro-acoustic transducer is mounted in a first one of the arms that is coupled to the lens region by the hinge, and wherein the cable is fixed at a first location to a circuit board in the other one of the arms, extends through the lens region, and is fixed at a second location proximate the electro-acoustic transducer in the first one of the arms, wherein the cable comprises at least one bend in a portion contained within the cavity for controlling tension on the cable during the movement of the arm relative to the lens region.

19. The audio eyeglasses of claim 18 , wherein an offset between the first and second openings causes the cable to exhibit the at least one bend in the portion between the first and second openings.
