Abstract: An earphone comprises a core module located at a front side of an ear in a wearing state and a hook structure at least a portion of which is located at a rear side of the ear in the wearing state. A free end of the core module not connected to the hook structure extends into a concha cavity of the ear in the wearing state. In the wearing state, a first inner side surface of the core module covers at least a portion of a tragus of the ear, a transition portion of the hook structure is located at the front side of the ear, and a second inner side surface of the transition is bent along the thickness direction of the core module toward a direction away from an outer side surface of of the core module with respect to the first inner side surface.

Abstract: The present disclosure provides a charging case for at least one earphone. Each of the at least one earphone may include a core module and a hook structure connected to the core module. The charging case may include a lower housing assembly. The lower housing assembly may be disposed with at least one profiling groove, and each of the at least one profiling groove may be configured to accommodate one of the at least one earphone. The lower housing assembly may be disposed with a first electrode terminal exposed in each of the at least one profiling groove, and an extension direction of the first electrode terminal may be inclined with respect to a thickness direction of the charging case. Therefore, the success rate of the connection of the electrode terminals can be improved.

Abstract: The present disclosure provides an earphone, comprising a core module and a hook structure. In a wearing state, the core module is disposed at a front side of an ear in a wearing state, and at least a portion of the hook structure is disposed at a rear side of the ear. A length of the core module is in a range of 22 mm-35 mm, which allows a free end of the core module to extend into a cavity of auricular concha. A transition portion of the hook structure is configured as a tapered structure, such that the earphone is smoother and more symmetrical in overall appearance. In the waring state and viewed along a direction of a human coronal axis, a connection end of the core module connected with the hook structure is closer to the top of the head of the user compared with the free end.

Abstract: The present disclosure provides an earphone, comprising a core module and a hook structure. In a wearing state, the core module is disposed on a front side of the ear, and at least a portion of the hook structure is disposed at a rear side of the ear. Orthographic projections of the hook structure and the core module on a reference plane perpendicular to a thickness direction do not overlap. The hook structure includes a battery housing and a flexible coating. A battery coupled with the core module is disposed in the battery housing, and the battery housing includes a cover housing and a battery compartment connected with the cover housing. The flexible coating is configured to cover the cover housing. A first reference line segment with the shortest length is provided between the orthographic projection of the hook structure and the orthographic projection of the core module.

Abstract: The present disclosure provides a charging case for at least one earphone. Each of the at least one earphone may include a core module and a hook structure connected to the core module. The charging case may include at least one profiling groove configured to accommodate one of the at least one earphone. Each of the at least one profiling groove may include a first profiling groove region corresponding to the core module and a second profiling groove region corresponding to the hook structure. A projection of the first profiling groove region and a projection of the second profiling groove region in the first reference direction overlap, and a projection of the first profiling groove region and a projection of the second profiling groove region in the second reference direction overlap. The first reference direction may be perpendicular to the second reference direction. With such arrangement, the charging case in the present disclosure can have a relatively small volume.

Abstract: The present disclosure provides a charging case for an earphone, comprising a lower housing assembly, an upper housing assembly, a main control circuit board, a magnetic suction structure, and an upper housing magnet. A Hall sensor is provided within the lower housing assembly, and the Hall sensor is electrically connected to the main control circuit board. The magnetic suction structure is configured to place an earphone in a magnetic suction manner, and when the upper housing assembly is in an open state with respect to the lower housing assembly, the Hall sensor is in a first state under an action of a magnetic field of the magnetic suction structure, and when the upper housing assembly is in a closed state with respect to the lower housing assembly, the upper housing magnet causes the Hall sensor to switch to a second state different from the first state.

Abstract: The present disclosure is related primarily to a charging case for earphones. The earphones may include a core module and a hook structure connected to the core module. The charging case may include a lower housing assembly provided with a profiling groove for accommodating the earphones, the profiling groove includes a first profiling groove region corresponding to the core module and a second profiling groove region corresponding to the hook structure; when the earphones are accommodated in the profiling groove, in an extension direction of the hook structure, a movable gap between a portion of the hook structure away from the core module and a side wall of the second profiling groove region is greater than a movable gap between the core module and a side wall of the first profiling groove region. With such arrangement, a success rate of the earphones entering the charging case can be improved.
