Referring to fig. 1, as can be seen from the foregoing description, the ear-returning earphone 100 of the present application may be, for example, an ear-hanging earphone, based on which the earphone housing 10 may further include a first housing 11 and a second housing 12, the first housing 11 and the second housing 12 are respectively used for mounting earphone components, the ear-returning earphone 100 further includes an ear-hanging bracket 40, the ear-hanging bracket 40 is connected to the first housing 11 and the second housing 12, and the ear-hanging bracket 40 is used for hanging on an ear of a human body.

Referring to fig. 2 and fig. 4 together, alternatively, the rotating body 21 may be a shaft, and the rotating body 21 may be disposed independently or may be disposed on the ear-return module 30, that is, the rotating body 21 may be integrally designed with the ear-return module 30. Illustratively, the rotating body 21 is provided to the ear-returning module 30, so that the connection of the ear-returning module 30 and the rotating body 21 can be simplified, while the rotational connection of the ear-returning module 30 with the earphone housing 10 through the rotating body 21 is facilitated.

The elastic body 22a is in interference fit with the inner wall of the first mounting hole 11a, and the deformation gap 223 is used for providing a space for the deformation portion 222 to deform relative to the mounting portion 221. The elastic main body 22a comprises the mounting part 221 and the deformation part 222, and the deformation of the deformation part 222 when the elastic piece 22 rotates enables the convex part 22b protruding out of the periphery of the deformation part 222 to be matched with each groove 111 one by one, so that the ear return module 30 can generate a click paragraph sense when rotating, a user can effectively sense the rotating process of the ear return module 30, better rotating handfeel is achieved, and the use experience of the user is improved.
