Abstract

Disclosed is an open earphone, comprising a sound production component and an ear hook. The ear hook may include a first portion and a second portion connected in sequence. The first portion may be hung between the auricle of a user and the head of the user, the second portion may extend toward a front outer side of the auricle and connect the sound production component, and the sound production component may be located close to the ear canal but not block the opening of the ear canal; wherein the sound production component and the auricle may have a first projection and a second projection on a sagittal plane, respectively, a centroid of the first projection may have 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 may be within a range of 0.25-0.6, the centroid of the first projection may have a second distance from an end point of the second projection in a sagittal axis direction, and a ratio of the second distance to a width of the second projection in the sagittal axis direction may be within a range of 0.4-0.7.

First claim

What is claimed is:

1 . An open earphone, 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 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 and connects to the sound production component, the sound production component is located close to the ear canal but does not block the opening of the ear canal, and the sound production component at least partially covers an antihelix area; wherein the sound production component has a first projection on a sagittal plane, and when the earphone is worn, an inclination angle of a projection of an upper sidewall or a lower sidewall of the sound production component on the sagittal plane relative to a horizontal direction is not greater than 25°.

2 . The open earphone of claim 1 , wherein a distance between a midpoint of a projection of an end of the sound production component on the sagittal plane and a projection of an edge of a cavity of auricular concha on the sagittal plane is not greater than 15 mm.

3 . The open earphone of claim 1 , wherein the inclination angle of the projection of the upper sidewall or the lower sidewall of the sound production component on the sagittal plane relative to the horizontal direction is not greater than 10°.

4 . The open earphone of claim 1 , wherein the end of the sound production component abuts against an inner contour of the auricle.

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

6 . The open earphone of claim 1 , wherein the auricle has a second projection on the sagittal plane, and a distance between a centroid of the first projection and a contour of the second projection is within a range of 13 mm-54 mm.

7 . The open earphone of claim 1 , wherein a distance between a 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 8 mm-45 mm.

8 . The open earphone of claim 1 , wherein when the earphone is not worn, 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 10 mm-50 mm.

9 . The open earphone of claim 1 , wherein a distance between a centroid of the first projection and a centroid of a projection of the opening of the ear canal on the sagittal plane is not greater than 25 mm.

10 . The open earphone of claim 1 , further comprising a battery compartment, which is located at an end of the ear hook away from the sound production component; wherein
when the earphone is not worn, a centroid of a projection of the sound production component on a specific reference plane has a third distance from a centroid of a projection of the battery compartment on the specific reference plane, and the third distance is within a range of 20 mm-31 mm.

11 . The open earphone of claim 10 , wherein when the earphone is worn, a centroid of the first projection has a fourth distance from a centroid of a projection of the battery compartment on the sagittal plane, and the fourth distance is within a range of 25 mm-40 mm.

12 . The open earphone of claim 11 , wherein a ratio of a difference between the fourth distance and the third distance to the fourth distance is within a range of 0.3-0.7.

13 . The open earphone of claim 1 , wherein the auricle has a second projection on the sagittal plane, and a distance between a midpoint of the projection of the upper sidewall of the sound production component on the sagittal plane and a highest point of the second projection is within a range of 12 mm-24 mm; and
a distance between a midpoint of the projection of the lower sidewall of the sound production component on the sagittal plane and the highest point of the second projection is within a range of 22 mm-34 mm.

14 . The open earphone of claim 1 , wherein a distance between a midpoint of the projection of the upper sidewall of the sound production component on the sagittal plane and a projection of a vertex of the ear hook on the sagittal plane is within a range of 13 mm-20 mm; and
a distance between a midpoint of the projection of the lower sidewall of the sound production component on the sagittal plane and the projection of the vertex of the ear hook on the sagittal plane is within a range of 22 mm-36 mm.

15 . The open earphone of claim 1 , wherein when the earphone is not worn, an inclination angle of the sound production component relative to a plane of the ear hook is not greater than 8°.

16 . The open earphone of claim 1 , wherein when the earphone is worn, a distance between a farthest point on the sound production component from a plane of the ear hook and the plane of the ear hook is within a range of 12 mm-19 mm.
