Abstract

Embodiments of the present disclosure provide an earphone, comprising a sound production component, comprising a transducer and a housing accommodating the transducer, a sound outlet hole being provided on an inner side surface of the sound production component, the inner side facing an auricle of a user, and the sound outlet hole being configured to transmit a sound produced by the transducer out of the housing toward an ear canal of the user; and an ear-hook, configured to place the sound production component at a position adjacent to the car canal but not blocking an ear canal opening in a wearing state; wherein, at least a portion of the sound production component inserts into a cavum concha.

an ear-hook, configured to place the sound production component at a position adjacent to the ear canal but not blocking an ear canal opening in a wearing state; wherein,
at least a portion of the sound production component inserts into a cavum concha, a distance between a projection of a rear side surface of the sound production component on a sagittal plane and a projection of an edge of the cavum concha on the sagittal plane ranges from 0 mm to 7.25 mm, and a distance between a center of the sound outlet hole and the rear side surface of the sound production component ranges from 8.15 mm to 12.25 mm.

2. The earphone according to claim 1 , wherein one or more pressure relief holes are provided on side surfaces of the sound production component other than the inner side surface, and a distance between a center of the one or more pressure relief holes and the rear side surface of the sound production component is in a range of 10.44 mm to 15.68 mm or 13.51 mm to 20.27 mm.

3. The earphone according to claim 1 , wherein a projection of the sound production component on the sagittal plane and a projection of the cavum concha on the sagittal plane have an overlapping region, and a ratio of an area of the overlapping region to an area of the projection of the cavum concha on the sagittal plane is not less than 44.01%.

4. The earphone according to claim 3 , wherein an area of the projection of the sound production component on the sagittal plane ranges from 202 mm 2 to 560 mm 2 .

5. The earphone according to claim 1 , wherein a distance between the center of the sound outlet hole and a lower side surface of the sound production component ranges from 4.05 mm to 6.05 mm; and a short-axis dimension of the sound production component ranges from 10 mm to 15 mm.

6. The earphone according to claim 2 , wherein at least one pressure relief hole of the one or more pressure relief holes comprises a first pressure relief hole, the first pressure relief hole being open on an upper side surface, an outer side surface, or a lower side surface of the sound production component, and a distance between a center of the first pressure relief hole and the rear side surface is in a range of 10.44 mm to 15.68 mm.

7. The earphone according to claim 6 , wherein
a distance between a projection point of the center of the sound outlet hole on the sagittal plane and a projection point of a center of the ear canal opening on the sagittal plane ranges from 2.2 mm to 3.8 mm; and
a distance between the projection point of the center of the first pressure relief hole on the sagittal plane and the projection point of the center of the ear canal opening on the sagittal plane ranges from 12 mm to 18 mm.

8. The earphone according to claim 6 , wherein
a distance between a projection point of the center of the sound outlet hole on the sagittal plane and a projection point of a ⅓ point of a lower boundary of the inner side surface on the sagittal plane ranges from 3.5 mm to 5.6 mm; and
a distance between a projection point of the center of the first pressure relief hole on the sagittal plane and the projection point of the ⅓ point of the lower boundary of the inner side surface on the sagittal plane ranges from 13.76 mm to 20.64 mm.

9. The earphone according to claim 6 , wherein
a thickness of the sound production component ranges from 6 mm to 12 mm; and
a distance between the center of the first pressure relief hole and the inner side surface of the sound production component facing the auricle ranges from 4.24 mm to 6.38 mm.

10. The earphone according to claim 2 , wherein at least one pressure relief hole of the one or more pressure relief holes comprises a second pressure relief hole, the second pressure relief hole being open on the upper side surface, the outer side surface, or the lower side surface of the sound production component, a distance between a center of the second pressure relief hole and the rear side surface is in a range of 13.51 mm to 20.27 mm.

11. The earphone according to claim 10 , wherein
a distance between a projection point of the center of the sound outlet hole on the sagittal plane and a projection point of a center of the ear canal opening on the sagittal plane ranges from 2.2 mm to 3.8 mm; and
a distance between a projection point of the center of the second pressure relief hole on the sagittal plane and the projection point of the center of the ear canal opening on the sagittal plane ranges from 6.88 mm to 10.32 mm.

12. The earphone according to claim 10 , wherein
a distance between a projection point of the center of the sound outlet hole on the sagittal plane and a projection point of a midpoint of an upper boundary of the inner side surface on the sagittal plane ranges from 10.0 mm to 15.2 mm; and
a distance between a projection point of the center of the second pressure relief hole on the sagittal plane and the projection point of the midpoint of the upper boundary of the inner side surface on the sagittal plane ranges from 14.4 mm to 21.6 mm.

13. The earphone according to claim 10 , wherein
a thickness of the sound production component ranges from 6 mm to 12 mm; and
a distance between the center of the second pressure relief hole and the inner side surface of the sound production component facing the auricle ranges from 4.24 mm to 6.38 mm.
