Abstract

A headset is provided. The headset includes: a hook hung on a user's neck; a pair of sound output units connected to both end parts of the hook; and a clipping module provided to at least one sound output unit and coupled to a cap worn by the user to allow the at least one sound output unit to be detachable.

First claim

What is claimed is:

1. A headset comprising:
a hook hung on a user's neck;
a pair of sound output units connected to both end parts of the hook; and
a clipping module provided to at least one of the sound output units, the clipping module configured to allow the at least one sound output unit to be detachably coupled to a cap worn by the user,
wherein each of the sound output units comprises:
a case;
a frame surrounding an outer peripheral surface of the case and including a first speaker hole formed at an edge portion; and
a speaker module installed inside the case,
wherein the clipping module comprises:
a guide sleeve extending from an inside of the case;
a plurality of hook shoulders extending in a length direction of the guide sleeve at an inner peripheral surface of the guide sleeve and arranged in a circumferential direction of the guide sleeve;
a fixing clip disposed at an inner surface of the case facing the user's ear;
a clip button penetrating the fixing clip to be inserted into the guide sleeve and moving with the fixing clip integrally to allow the fixing clip to be selectively in close contact with the inner surface of the case;
a stopper selectively hooked by the hook shoulder and pushing the clip button when separated from the hook shoulder; and
a spring in close contact one surface of the stopper and having an elastic force for pushing the stopper.

2. The headset according to claim 1 , wherein the clip button comprises:
a head part including a second speaker hole;
a hollow body part extending from the other surface of the head part and having a narrower diameter as it approaches an end part;
a plurality of push protrusions protruding from the end part of the body part and arranged spaced a predetermined interval from each other in a circumferential direction of the body part; and
a plurality of guide protrusions protruding from an outer peripheral surface of the body part and arranged spaced a predetermined interval from each other in the circumferential direction of the body part.

3. The headset according to claim 2 , wherein the plurality of guide projections are formed at points corresponding to the plurality of push protrusions; and
a center of the plurality of guide protrusions and a center of the push protrusions are disposed on the same line.

4. The headset according to claim 2 , wherein the guide sleeve extends from an inner surface of the case,
wherein the guide sleeve further comprises:
a sitting projection extending in a center direction of the guide sleeve from a bottom surface of the guide sleeve; and
a plurality of guide ribs protruding from an inner peripheral surface of the guide sleeve, extending in a length direction of the guide sleeve, and arranged spaced a predetermined interval from each other in a circumferential direction of the guide sleeve.

5. The headset according to claim 4 , wherein guide grooves are formed between the adjacent guide ribs; and
the guide protrusions are inserted into the guide grooves to guide a movement of the clip button.

6. The headset according to claim 5 , wherein the hook shoulder is formed between the adjacent guide ribs; and
the guide groove and the hook shoulder are alternately formed in the circumferential direction of the guide sleeve.

7. The headset according to claim 6 , wherein an inclined surface inclined at a predetermined angle is defined at an end part of the guide rib; and
the hook shoulder is inclined to be disposed on the same line as the inclined surface of the guide rib.

8. The headset according to claim 7 , wherein the stopper comprises:
a base having one surface where the spring is seated;
a stopper body extending from the other surface of the base; and
a plurality of hook protrusions protruding from an outer peripheral surface of the stopper body in a radial direction and moving along the guide groove.

9. The headset according to claim 8 , wherein each of the plurality of hook protrusions forms a push surface selectively contacting the push protrusion; and
the push surface is inclined at an angle to match a shape of the inclined surface of the guide rib and the hook shoulder.

10. The headset according to claim 9 , wherein when the clip button is pushed, the hook protrusion is pushed by the push protrusion and moves along the guide groove;
the spring is compressed; and
when a force for pushing the clip button is removed at a point where the hook protrusion is out of the guide groove, the hook protrusion rotates along the inclined surface of the guide rib by the restoring force of the spring and is seated on the hook shoulder.

11. The headset according to claim 10 , wherein the clip button is retreated to a point where the hook shoulder is seated on the hook shoulder; and
the clip button is fixed by a frictional force between the outer peripheral surface of the clip button and the sitting projection at a point where the hook protrusion is seated at the hook shoulder.

12. The headset according to 11 , wherein when the clip button is pushed again, the hook protrusion is pushed by the push protrusion and separated from the sitting projection;
the spring is compressed;
when a force for pushing the clip button is removed at a point where the hook protrusion is out of the guide rib, the hook protrusion rotates along the inclined surface of the guide rib by the restoring force of the spring and is inserted into the guide groove; and
the clip button moves as pushed by the hook protrusion and is retreated until the guide protrusion contacts the sitting projection.

13. The headset according to claim 12 , wherein the elastic force of the spring is greater than a frictional force between the outer peripheral surface of the clip button and the sitting projection.

14. The headset according to claim 2 , wherein the sound output unit is rotatable at a predetermined angle from the hook and is withdrawable in a direction away from the end part of the hook.

15. The headset according to claim 14 , wherein the sound output unit is rotatable from a first position where the second speaker holes stand to face each other to a second position where the second speaker holes face the same direction or inversely rotatable from the second position to the first position.

16. The headset according to claim 15 , wherein a rotation angle from the first position to the second position is 90°.

17. The headset according to claim 14 , wherein the sound output unit comprises:
a connecting neck extending from an edge of the frame; and
a plurality of insertion protrusions protruding from an end part of the connecting neck,
wherein the plurality of insertion protrusions are arranged spaced at a predetermined angle from each other in a circumferential direction of the connecting neck.

18. The headset according to claim 17 , wherein the hook comprises:
a center hole formed at an inner center; and
a plurality of insertion holes extending from an edge of the center hole radially and including a plurality of insertion holes in which the plurality of insertion protrusions are respectively inserted,
wherein the plurality of insertion holes are arranged spaced at a predetermined angle from each other in a circumferential direction of the center hole.

19. The headset according to claim 18 , wherein the number of the plurality of insertion protrusions is less than the number of the plurality of insertion holes.

20. The headset according to claim 18 , further comprising:
an elastic member inserted into the hook throu
