Abstract

The present disclosure discloses an earphone. The earphone may include a hook-shaped component, a connecting component, and a holding component. When the earphone is in a wearing state, the hook-shaped component may be configured to hang between a rear side of an ear of a user and a head of the user. The holding component may be configured to contact a front side of the ear. The connecting component may be configured to connect the hook-shaped component and the holding component and extend from the head to an outside of the head to cooperate with the hook-shaped component to provide the holding component with a pressing force on the front side of the ear.

First claim

What is claimed is:

1. An earphone, comprising: a hook-shaped component, a connecting component, and a holding component, wherein when the earphone is in a wearing state,
the hook-shaped component is configured to hang between a rear side of an ear of a user and a head of the user,
the holding component is configured to contact a front side of the ear, wherein a core configured to generate a sound is set at the holding component, and the holding component does not cover an external ear canal of the ear, and
the connecting component is configured to connect the hook-shaped component and the holding component and extend from the head along a coronal axis of the user towards an outside of the head to cooperate with the hook-shaped component to provide the holding component with a pressing force on the front side of the ear.

2. The earphone of claim 1 , wherein in a direction from a first connection point between the hook-shaped component and the connecting component to a free end of the hook-shaped component,
the hook-shaped component is bent toward the rear side of the ear to form a first contact point with the rear side of the ear, and
the holding component forms a second contact point with the front side of the ear, wherein a distance between the first contact point and the second contact point along an extending direction of the connecting component in a natural state is smaller than that in a wearing state to provide the holding component with the pressing force on the front side of the ear.

3. The earphone of claim 2 , wherein the hook-shaped component further forms a third contact point with the rear side of the ear, the third contact point being located between the first connection point and the first contact point and being closer to the first connection point, wherein
a distance between projections of the first contact point and the third contact point on a reference plane perpendicular to the extending direction of the connecting component in the natural state is smaller than that in the wearing state.

4. The earphone of claim 1 , wherein in a direction from a first connection point between the hook-shaped component and the connecting component to a free end of the hook-shaped component, the hook-shaped component is bent toward the head to form a first contact point and a second contact point with the head, wherein
the first contact point is located between the second contact point and the first connection point, so that the hook-shaped component forms a lever structure with the first contact point as a fulcrum; and
a force directed to the outside of the head and provided by the head at the second contact point causes a force directed to the head at the first connection point by the lever structure to provide the holding component with the pressing force on the front side of the ear through the connecting component.

5. The earphone of claim 1 , wherein the holding component extends and is held in a concha boat of the ear.

6. The earphone of claim 1 , wherein an elastic metal wire is arranged inside the hook-shaped component, the elastic metal wire has a major axis direction and a minor axis direction orthogonal to each other on a cross section of the elastic metal wire, and a size of the elastic metal wire in the major axis direction is greater than a size of the elastic metal wire in the minor axis direction.

7. The earphone of claim 6 , wherein the elastic metal wire is in a shape of an arc in the minor axis direction, and a ratio of a height of the arc to the size of the elastic metal wire in the major axis direction is within a range of 0.1-0.4.

8. The earphone of claim 1 , further including an extending component, wherein
the extending component is arranged on the holding component, and extends into any one of a concha cavity, a concha boat, a triangular fossa, and a scapha of the ear in the wearing state; or
the extending component is arranged on the hook-shaped component, and hooks a helix or an antihelix of the ear in the wearing state.

9. The earphone of claim 8 , wherein the extending component is sleeved on the holding component through an elastic sleeve.

10. The earphone of claim 1 , wherein in the wearing state, the connecting component is connected to a lower edge of the holding component.

11. The earphone of claim 1 , wherein the holding component has a thickness direction, a length direction, and a height direction orthogonal to each other, the thickness direction is configured as a direction in which the holding component is close to or away from the ear in the wearing state, and the height direction is configured as a direction in which the holding component is close to or away from a top of the user's head in the wearing state, wherein
in the natural state, and viewed from a side of the earphone facing the top of the user's head in the wearing state, the holding component is at least spaced apart from a section of the hook-shaped component close to the connecting component in the thickness direction; and
the connecting component is arranged in a shape of an arc and connected between the holding component and the hook-shaped component.

12. The earphone of claim 11 , wherein in the thickness direction, a minimum distance between the section of the hook-shaped component close to the connecting component and the holding component is greater than 0 and smaller than or equal to 5 mm.

13. The earphone of claim 11 , wherein
edges of the section of the hook-shaped component close to the connecting component, the connecting component, and the holding component facing the ear are arranged in a shape of a circuitous arc; and
in a reference direction that passes through a roundabout inflection point of the circuitous arc and is parallel to the length direction, a minimum width of the circuitous arc along the thickness direction at a position 3 mm away from the roundabout inflection point is in a range of 1 mm to 5 mm.

14. The earphone of claim 11 , wherein a side of the holding component facing the ear is configured with a sound hole, and a distance between a center of the sound hole and the section of the hook-shaped component close to the connecting component in the thickness direction is in a range of 3 mm to 6 mm.

15. The earphone of claim 11 , wherein a side of the holding component facing the ear includes a first region and a second region, wherein
the first region is configured with a sound hole; and
the second region is farther away from the connecting component than the first region and is more protruding toward the ear than the first region, so as to allow the sound hole to be spaced from the ear in the wearing state.

16. The earphone of claim 15 , wherein a distance between the second region and the section of the hook-shaped component close to the connecting component in the thickness direction is in a range of 1 mm to 5 mm.

17. The earphone of claim 16 , wherein an orthographic projection of the section of the hook-shaped component close to the connecting component in the thickness direction partially overlaps the second region.

18. The earphone of claim 15 , wherein a maximum protrusion height of the second region relative to the first region in the thickness direction is greater than or equal to 1 mm.

19. The earphone of claim 1 , wherein the holding component is in contact with an antihelix of the ear.

20. The earphone of claim 1 , wherein a roughness of a surface of the hook-shaped component is in a range of 0.1-3 μm.
