Abstract

The present disclosure provides an open earphone comprising: a sound production component including a transducer and a housing accommodating the transducer; and an ear hook including a first portion of the ear hook and a second portion of the ear hook. The first portion of the ear hook is hung between an auricle and a head of a user, and the second portion of the ear hook extends towards a side of the auricle away from the head and connects with the sound production component to place the sound production component in a position near an ear canal but not blocking the ear canal, the housing and the first portion of the ear hook clamp the auricle of the user, and provide a clamping force in a range of 0.03 N to 1 N to the auricle of the user.

Claims (19)

1. An open earphone, comprising:

a sound production component including a transducer and a housing accommodating the transducer; and

an ear hook including a first portion of the ear hook and a second portion of the ear hook, wherein the first portion of the ear hook is hung between an auricle and a head of a user, and the second portion of the ear hook extends towards a side of the auricle away from the head and connects with the sound production component to place the sound production component in a position near an ear canal but not blocking the ear canal;

the housing and the first portion of the ear hook clamp the auricle of the user, and provide a clamping force in a range of 0.03 N to 1 N to the auricle of the user.

2. The open earphone of claim 1 , wherein in a wearing state, the housing is at least partially inserted into an inferior concha of the user, and a portion of the housing at least partially inserted into the inferior concha of the user includes at least one clamping region contacted with a side wall of the inferior concha of the user.

3. The open earphone of claim 2 , wherein in the wearing state, an angle between a direction of a clamping force and a sagittal plane of the user is in a range of −30° to 30°.

4. The open earphone of claim 2 , wherein the ear hook includes a clamping fulcrum located at a position of the ear hook with a minimum cross-sectional area, and a clamping coefficient of the ear hook based on the clamping fulcrum is in a range of 10 N/m to 30 N/m.

5. The open earphone of claim 4 , wherein in the wearing state, a minimum distance between the sound production component and the first portion of the ear hook is not less than 2 mm.

6. The open earphone of claim 5 , wherein in the wearing state, a distance between a center of the clamping region and the clamping fulcrum is in a range of 20 mm to 40 mm.

7. The open earphone of claim 5 , wherein in the wearing state, a distance between a clamping point of the ear hook on the first portion of the ear hook and the clamping fulcrum is in a range of 25 mm to 45 mm.

8. The open earphone of claim 5 , wherein in the wearing state, an angle between a first connection line from the center of the clamping region to the clamping fulcrum and a second connection line from a clamping point of the ear hook to the clamping fulcrum is in a range of 6° to 12°.

9. The open earphone of claim 2 , wherein the clamping region and/or an inner side of the clamping region is provided with a flexible material, and a Shore hardness of the flexible material is in a range of 0 HA to 40 HA.

10. The open earphone of claim 1 , wherein in the wearing state, the housing is at least partially located at an antihelix, and a side of the housing toward the antihelix of the user includes a clamping region contacted with the antihelix of the user.

11. The open earphone of claim 10 , wherein in the wearing state, an angle between a direction of a clamping force and a sagittal plane of the user is in a range of 60° to 120°.

12. The open earphone of claim 1 , wherein the ear hook is composed of a metal wire and a wrapping layer.

13. The open earphone of claim 12 , wherein an elastic modulus of the metal wire is in a range of 20 GPa to 50 GPa.

14. The open earphone of claim 12 , wherein a diameter of the metal wire is in a range of 0.5 mm to 1 mm.

15. The open earphone of claim 12 , wherein a density of the metal wire is in a range of 5 g/cm 3 to 7 g/cm 3 .

16. The open earphone of claim 12 , wherein a Shore hardness of the wrapping layer is in a range of 10 HA to 80 HA.
