Abstract: A rotary earhanger structure of a wireless earphone includes an earhanger unit and a movable connection sleeve rotationally connected therewith. One end of the earhanger unit includes a first inclined surface portion extending obliquely in a preset rotational direction. The movable connection sleeve has a second inclined surface portion cooperatively connected with the first inclined surface portion. The movable connection sleeve is connected with an elastic member for driving the movable connection sleeve in a direction close to the earhanger unit. The external force rotates the earhanger unit in the preset rotating direction to adjust the wearing angle. When the earhanger unit is not subjected to the external force, the movable connection sleeve moves in the direction close to the earhanger unit under the force of the elastic member, so that the automatic reset function after the earhanger rotation is realized, thereby simplifying user operation and improving user experience.
