Abstract

The present disclosure provides an earphone comprising a sound production component and an ear hook. In a wearing state, the ear hook is configured to place the sound production component at a position near an ear canal but not blocking the ear canal. An inner contour of the ear hook's projection on a user's sagittal plane includes a first curve having an extremum point in a first direction. The first direction is perpendicular to a long-axis direction of a projection of the sound production component on the sagittal plane. The extremum point is located behind a projection point of an upper vertex of the ear hook on the sagittal plane, and the upper vertex is a highest point of an inner contour of the ear hook along the user's vertical axis. An inclination angle of the long-axis direction relative to a horizontal direction is within a range of 13°-21°.

an inner contour of a projection of the ear hook on a user's sagittal plane includes a first curve, the first curve has an extremum point in a first direction, and the first direction is perpendicular to a long-axis direction of a projection of the sound production component on the user's sagittal plane;
the extremum point is located behind a projection point of an upper vertex of the ear hook on the user's sagittal plane, and the upper vertex is a highest point of an inner contour of the ear hook along a vertical axis of the user in the wearing state; and
in the wearing state, a distance between a midpoint of a projection of an upper side surface of the sound production component on the user's sagittal plane and the projection point of the upper vertex on the user's sagittal plane is within a range of 17 mm-36 mm.

2. The earphone of claim 1 , wherein in the wearing state, a distance between a midpoint of a projection of a lower side surface of the sound production component on the user's sagittal plane and the projection point of the upper vertex on the user's sagittal plane is within a range of 28 mm-52 mm.

3. The earphone of claim 2 , wherein in the wearing state, a distance between the midpoint of the projection of the upper side surface of the sound production component on the user's sagittal plane and a highest point of a projection of the auricle on the user's sagittal plane is within a range of 24 mm-36 mm.

4. The earphone of claim 3 , wherein in the wearing state, a distance between the midpoint of the projection of the lower side surface of the sound production component on the user's sagittal plane and the highest point of the projection of the auricle on the user's sagittal plane is within a range of 28 mm-52 mm.

5. The earphone of claim 1 , wherein in a non-wearing state, a distance from a point on the ear hook farthest from an inner side surface of the sound production component to the inner side surface of the sound production component is within a range of 6 mm-9 mm.
