CLAIMS

I/We claim:

1. A headset, comprising:

a headpiece;

an earpiece;

an arm extending between the headpiece and the earpiece, wherein the arm is movable between a lengthened state and a shortened state, and wherein the arm includes—

an elongate first segment through which the arm is operably connected to the earpiece, the first segment having a first end portion and an opposite second end portion further from the earpiece than the first end portion, and

an elongate second segment through which the arm is operably connected to the headpiece, the second segment defining an interior region within which the second end portion of the first segment is disposed and longitudinally movable; and

a cord extending between the headpiece and the earpiece through the arm, wherein increased slack in the cord preferentially gathers within the interior region of the second segment when the arm moves from the lengthened state toward the shortened state.

2. The headset of claim 1 wherein the first and second segments have a telescoping arrangement in which longitudinal movement of the first segment relative to the second segment changes a length of the arm and changes a volume of a portion of the interior region of the second segment within which increased slack in the cord preferentially gathers when the arm moves from the lengthened state toward the shortened state.

3. The headset of claim 1 wherein:

the first segment includes a lip at the at the second end portion of the first segment; the first segment defines a channel extending from the lip toward the first end portion of the first segment; and

the lip urges increased slack in the cord to remain within the interior region of the second segment outside the channel when the arm moves from the lengthened state toward the shortened state.

4. The headset of claim 3 wherein the channel tapers, at the lip, inwardly toward the first end portion of the first segment.

5. The headset of claim 3 wherein a transverse cross-sectional area of the channel is sufficiently small to reduce gathering of increased slack in the cord within the channel when the arm moves from the lengthened state toward the shortened state.

6. The headset of claim 3 wherein:

the channel includes a straight bore through the first segment; and

the cord extends loosely through the channel.

7. The headset of claim 1 wherein:

the arm includes a hinge operable to rotate the arm about an axis and thereby move the arm relative to the headpiece between a folded state and an unfolded state; and

increased slack in the cord preferentially gathers within the interior region of the second segment when the arm moves from the folded state toward the unfolded state.

8. The headset of claim 7 wherein:

the hinge includes an axle extending, at the axis, laterally through the interior region of the second segment; and

the cord bends around the axle when the arm moves from the unfolded state toward the folded state while the arm is in the lengthened state.

9. The headset of claim 7 wherein the second end portion of the first segment is longitudinally spaced apart from the axis when the arm is in the shortened state.

10. The headset of claim 7 wherein:

the first segment includes a lip at the second end portion of the first segment;

the first segment includes an outwardly opening annular groove at the at the second end portion of the first segment set back from the lip;

the headset further comprises an o-ring seated in the groove; and

friction between the o-ring and the second segment resists movement of the arm between the lengthened and shortened states.

11. The headset of claim 7 wherein increased slack in the cord preferentially gathers within a portion of the interior region of the second segment between the axis and the second end portion of the first segment when the arm moves from the lengthened state toward the shortened state.

12. The headset of claim 11 wherein increased slack in the cord preferentially gathers within the portion of the interior region of the second segment between the axis and the second end portion of the first segment when the arm moves from the folded state toward the unfolded state.

13. The headset of claim 7 wherein:

the second segment includes a slot between the headpiece and the interior region of the second segment; and

the cord extends into the interior region of the second segment toward the earpiece through the slot.

14. The headset of claim 13 wherein a length of the slot is substantially perpendicular to the axis.

15. A headset according to any non-conflicting combination of claims 1-14.

16. A headset, comprising:

a headpiece;

an earpiece;

an arm extending between the headpiece and the earpiece, wherein the arm defines an interior region, and wherein the arm includes—

a hinge operable to rotate the arm about an axis and thereby move the arm relative to the headpiece between a folded state and an unfolded state, and

a slot between the headpiece and the interior region of the arm; and a cord extending between the headpiece and the earpiece through the arm, wherein the cord extends into the interior region of the arm toward the earpiece through the slot, and wherein increased slack in the cord preferentially gathers within a portion of the interior region between the axis and the earpiece when the arm moves from the folded state toward the unfolded state.

17. The headset of claim 15 wherein:

the hinge includes an axle extending, at the axis, laterally through the interior region of the arm; and

the cord bends around the axle when the arm moves from the unfolded state toward the folded state.

18. The headset of claim 15 wherein a length of the slot is substantially perpendicular to the axis.

19. A headset according to any non-conflicting combination of claims 16-18.

20. A method for operating a headset including a headpiece, an earpiece, an arm extending therebetween, and a cord extending through the arm, the method comprising:

moving a first segment of the arm relative to a second segment of the arm to reduce a length of the arm and thereby move the arm from a lengthened state toward a shortened state, wherein increased slack in the cord preferentially gathers within an interior region of the second segment when the arm moves from the lengthened state toward the shortened state; and

operating a hinge of the arm to rotate the arm about an axis and thereby move the arm relative to the headpiece from a folded state toward an unfolded state, wherein increased slack in the cord preferentially gathers within the interior region of the second segment when the arm moves from the folded state toward the unfolded state.

21. The method of claim 18 wherein moving the first segment includes moving the first segment telescopically relative to the second segment and thereby reducing a volume of a portion of the interior region of the second segment within which increased slack in the cord preferentially gathers when the arm moves from the lengthened state toward the shortened state.

22. The method of claim 18 wherein operating the hinge includes bending the cord around an axle that extends, at the axis, laterally through the interior region of the second segment.

23. A method according to any non-conflicting combination of claims 20-22.
