10 . The earphone of claim 1 , the ear hook further comprises:
a connecting component configured to connect the hook-shaped component and the holding component and extend from the head along a coronal axis of the user towards an outside of the head to cooperate with the hook-shaped component to provide the holding component with a pressing force on the front side of the ear.
11 . The earphone of claim 10 , wherein in a direction from a first connection point between the hook-shaped component and the connecting component to a free end of the hook-shaped component,
the hook-shaped component is bent toward the rear side of the ear to form a first contact point with the rear side of the ear, and
the holding component forms a second contact point with the front side of the ear, wherein a distance between the first contact point and the second contact point along an extending direction of the connecting component in a natural state is smaller than that in a wearing state to provide the holding component with the pressing force on the front side of the ear.
12 . The earphone of claim 11 , wherein the hook-shaped component further forms a third contact point with the rear side of the ear, the third contact point being located between the first connection point and the first contact point and being closer to the first connection point, wherein
a distance between projections of the first contact point and the third contact point on a reference plane perpendicular to the extending direction of the connecting component in the natural state is smaller than that in the wearing state.
13 . The earphone of claim 10 , wherein in a direction from a first connection point between the hook-shaped component and the connecting component to a free end of the hook-shaped component, the hook-shaped component is bent toward the head to form a first contact point and a second contact point with the head, wherein
the first contact point is located between the second contact point and the first connection point, so that the hook-shaped component forms a lever structure with the first contact point as a fulcrum; and
a force directed to the outside of the head and provided by the head at the second contact point causes a force directed to the head at the first connection point by the lever structure to provide the holding component with the pressing force on the front side of the ear through the connecting component.
