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.
