Abstract

Embodiments of the present disclosure provide a headphone including a sound production component and an ear hook. The ear hook includes a first portion and a second portion connected in sequence. The first portion being hooked up between an ear auricle and a head of a user, and the second portion is configured to be hang between an auricle of a user and a head of the user, the second portion extends toward a front outer side of the auricle, connects with the sound production component, and is configured to place the sound production component at a position close to an ear canal without blocking an opening of the ear canal, and at least a portion of the sound production component is inserted into an concha cavity. The sound production component and the first portion of the ear hook clamp the auricle in a wearing state.

First claim

What is claimed is:

1. A headphone, comprising:

wherein the sound production component and the first portion of the ear hook clamp the auricle in a wearing state, a minimum distance between the sound production component and the first portion of the ear hook in the wearing state has a difference with a minimum distance between the sound production component and the first portion of the ear hook in a non-wearing state, and the difference is not less than 1 mm; and
the sound production component has a first projection on a sagittal plane of the user, and a distance between a centroid of the first projection and a projection of an edge of the concha cavity of the auricle on the sagittal plane is within a range of 4 mm-25 mm.

2. The headphone of claim 1 , wherein, in the non-wearing state, the minimum distance between the sound production component and the first portion of the ear hook is not larger than 3 mm.

3. The headphone of claim 1 , wherein the auricle has a second projection on the sagittal plane, the centroid of the first projection has a first distance from a highest point of the second projection in a vertical axis direction, a ratio of the first distance to a height of the second projection in the vertical axis direction is within a range of 0.25-0.6, the centroid of the first projection has a second distance from an end point of the second projection on a sagittal axis direction, and a ratio of the second distance to a width of the second projection in the sagittal axis direction is within a range of 0.4-0.7.

4. The headphone of claim 1 , wherein, in the non-wearing state, an inclination angle of the sound production component relative to a plane of the ear hook is within a range of 15°-28° or an inclination angle of the sound production component relative to a plane of the auricle is within a range of 40°-60°.

5. The headphone of claim 1 , wherein a distance between a farthest point on the sound production component from the plane of the ear hook and the plane of the ear hook is within a range of 11.2 mm-16.8 mm.

6. The headphone of claim 4 , wherein an included angle between a direction of a clamping force of the sound production component and the first portion of the ear hook to the auricle and the sagittal plane is within a range of −30°-30°.

7. The headphone of claim 1 , wherein the at least a portion of the sound production component inserted into the concha cavity includes at least one clamping region in contact with the edge of the concha cavity; and the ear hook includes a clamping fulcrum located at a position with a smallest cross-sectional area on the ear hook, and a clamping coefficient of the ear hook based on the clamping fulcrum is within a range of 10 N/m-30 N/m.

8. The headphone of claim 7 , wherein a distance between a midpoint of a projection of an upper sidewall of the sound production component on the sagittal plane and a projection of the clamping fulcrum on the sagittal plane is within a range of 21 mm-32 mm; and a distance between a midpoint of a projection of a lower sidewall of the sound production component on the sagittal plane and the projection of the clamping fulcrum on the sagittal plane is within a range of 32 mm-48 mm.

9. The headphone of claim 7 , wherein a distance between a center of the clamping region and the clamping fulcrum is within a range of 20 mm-40 mm.

10. The headphone of claim 9 , wherein a distance between an ear hook clamping point on the first portion of the ear hook and the clamping fulcrum is within a range of 25 mm-45 mm.

11. The headphone of claim 10 , wherein an included angle between a first connection line from the center of the clamping region to the clamping fulcrum and a second connection line from the ear hook clamping point to the clamping fulcrum is within a range of 6°-12°.

12. The headphone of claim 11 , wherein in the wearing state, a distance between the centroid of the first projection and a projection of the first portion of the ear hook on the sagittal plane is within a range of 18 mm-43 mm.

13. The headphone of claim 12 , wherein in the non-wearing state, a distance between a centroid of a projection of the sound production component on a specific reference plane and a centroid of a projection of the first portion of the ear hook on the specific reference plane is within a range of 13 mm-38 mm.

14. The headphone of claim 1 , wherein the headphone further comprises a battery compartment, the battery compartment being located at an end of the ear hook away from the sound production component; and
in the non-wearing state, the centroid of the projection of the sound production component on a specific reference surface has a third distance from a centroid of a projection of the battery compartment on the specific reference surface, the third distance being within a range of 16.7 mm-25 mm.

15. The headphone of claim 14 , wherein in the wearing state, the centroid of the first projection has a fourth distance from a centroid of a projection of the battery compartment on the sagittal plane, the fourth distance being within a range of 20 mm-30 mm.

16. The headphone of claim 15 , wherein a ratio of a difference between the fourth distance and the third distance to the fourth distance is within a range of 0.3-0.8.

17. The headphone of claim 1 , wherein a clamping force of the sound production component and the first portion of the ear hook to the auricle is within a range of 0.03 N-1 N.

18. A headphone, comprising:
a sound production component; and
an ear hook including a first portion and a second portion connected in sequence, wherein the first portion is configured to be hung between an auricle of a user and a head of the user, the second portion extends toward a front outer side of the auricle, connects with the sound production component, and is configured to place the sound production component at a position close to an ear canal without blocking an opening of the ear canal, and at least a portion of the sound production component covers an antihelix region, wherein
