Earphones

An earphone, comprising a core module and a hook structure connected with the core module, wherein

• the core module is disposed at a front side of an ear in a wearing state, at least a portion of the hook structure is disposed at a rear side of the ear in the wearing state, and an orthographic projection of the hook structure and an orthographic projection of the core module on a reference plane perpendicular to a thickness direction do not overlap, the thickness direction being a direction in which the core module is close to or away from the ear in the wearing state, and
• the hook structure includes a battery housing and a flexible coating, a battery coupled with the core module is disposed in the battery housing, the battery housing includes a cover housing and a battery compartment connected with the cover housing, and the flexible coating covers the cover housing, a first reference line segment with the shortest length being provided between the orthographic projection of the hook structure and the orthographic projection of the core module, and a point at which the first reference line segment intersects with the orthographic projection of the hook structure being located in a section where the flexible coating overlaps with the cover housing.
