a pair of arms extending from the lens region; a hinge coupling each of the pair of arms with the lens region; and a cable extending through each hinge, where each hinge includes: a body defining a cavity accommodating the cable; and a hinge mechanism within the body, the hinge mechanism having: a spring located in the lens region, the spring including at least one lever arm extending within the cavity; and a cam member contacting the lever arm of the spring, where the cam member includes: a first contact surface for resisting kickback from the spring when the audio eyeglasses are in a fully open position, and a second, distinct contact surface for resisting kickback from the spring when the audio eyeglasses are in a fully closed position. ## Claims ### 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; a hinge coupling each of the pair of arms with the lens region; and a cable extending through each hinge, wherein each hinge comprises: a body defining a cavity accommodating the cable; and a hinge mechanism within the body, the hinge mechanism comprising: a spring located in the lens region, the spring comprising at least one lever arm extending within the cavity; and a cam member contacting the lever arm of the spring, wherein the cam member comprises: a first contact surface for resisting kickback from the spring when the audio eyeglasses are in a fully open position, and a second, distinct contact surface for resisting kickback from the spring when the audio eyeglasses are in a fully closed position. ### Claim 2 (depends on 1) The audio eyeglasses of claim 1, wherein the first contact surface has a first surface profile and the second contact surface has a second, distinct surface profile. ### Claim 3 (depends on 1) The audio eyeglasses of claim 1, wherein the second contact surface has a notch that limits an area of contact with the at least one lever arm. ### Claim 4 (depends on 3) The audio eyeglasses of claim 3, wherein in the fully closed position, the at least one lever arm applies a force to the second contact surface to maintain the fully closed position regardless of an orientation of the audio eyeglasses. ### Claim 5 (depends on 3) The audio eyeglasses of claim 3, wherein in the fully open position, the at least one lever arm applies a force to the first contact surface to maintain the fully open position regardless of an orientation of the audio eyeglasses. ### Claim 6 (depends on 1) The audio eyeglasses of claim 1, further comprising a pin about which the cam is configured to rotate, wherein the cam comprises a vertically extending hole accommodating the pin. ### Claim 7 (depends on 1) The audio eyeglasses of claim 1, wherein the spring comprises a double-torsion spring. ### Claim 8 (depends on 1) The audio eyeglasses of claim 1, wherein the lever arm comprises a notch in a contact surface that complements a protrusion in the second contact surface. ### Claim 9 (depends on 1) The audio eyeglasses of claim 1, further comprising: an electro-acoustic transducer at least partially housed in the frame and comprising a sound-radiating surface for providing an audio output. ### Claim 10 (depends on 1) The audio eyeglasses of claim 1, further comprising at least one microphone in the frame, wherein the hinge permits movement of the additional section relative to the first section. ### Claim 11 (depends on 1) The audio eyeglasses of claim 1, 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 cable comprises a printed circuit board (PCB), and wherein the PCB is thinner in a region contained within the hinge than in a distinct region within the pathway or the additional pathway. ### Claim 12 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; a hinge coupling each of the pair of arms with the lens region; and a cable extending through each hinge, wherein each hinge comprises: a body defining a cavity accommodating the cable; and a hinge mechanism within the body, the hinge mechanism comprising: a spring located in the lens region, the spring comprising at least one lever arm extending within the cavity; and a cam member contacting the lever arm of the spring, wherein the cam member comprises a notch along a contact surface for resisting kickback from the spring when the audio eyeglasses are in a fully closed position. ### Claim 13 (depends on 12) The audio eyeglasses of claim 12, wherein the cam member comprises a bend for resisting kickback from the spring when the audio eyeglasses are in a fully open position. ### Claim 14 (depends on 12) The audio eyeglasses of claim 12, wherein the cam comprises a protrusion adjacent to the notch. ### Claim 15 (depends on 14) The audio eyeglasses of claim 14, wherein in the fully closed position, the at least one lever arm contacts the cam member only at the protrusion. ### Claim 16 (depends on 14) The audio eyeglasses of claim 14, wherein the lever arm comprises a notch in a contact surface to complement a protrusion in the second contact surface. ### Claim 17 (depends on 12) The audio eyeglasses of claim 12, further comprising a pin about which the cam is configured to rotate, wherein the cam comprises a vertically extending hole accommodating the pin. ### Claim 18 (depends on 12) The audio eyeglasses of claim 12, wherein the spring comprises a double-torsion spring. ### Claim 19 (depends on 12) The audio eyeglasses of claim 12, further comprising: an electro-acoustic transducer at least partially housed in the frame and comprising a sound-radiating surface for providing an audio output; and at least one microphone in the frame, wherein the hinge permits movement of the additional section relative to the first section. ### Claim 20 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; a hinge coupling each of the pair of arms with the lens region; and a cable extending through each hinge, wherein each hinge comprises: a body defining a cavity accommodating the cable; and a hinge mechanism within the body, the hinge mechanism comprising: a spring located in the lens region, the spring comprising at least one lever arm extending within the cavity; and a cam member contacting the lever arm of the spring, wherein the cam member comprises a set of contact surfaces for directing a force from the at least one lever arm to separately maintain the audio eyeglasses in a fully closed position, and a fully open position, respectively.
