Referring to fig. 1, an embodiment of the present invention provides a bone conduction earphone, which includes two vibrating portions 1, two ear-hanging portions 2 and a rear-hanging portion 4;

the rear hanging part 4 is connected between the two ear hanging parts 2;

each vibration part 1 is rotatably connected with a corresponding ear-hook part 2 through a rotating component 3, so that the vibration part 1 can rotate relative to the ear-hook part 2 to fit the head of a wearer.

In the wearing state, the two vibration parts 1 are respectively positioned on the left side and the right side of the head of the wearer, and under the cooperation effect of the two ear-hanging parts 2 and the rear-hanging part 4, the two vibration parts 1 can clamp the head of the wearer and contact with the skin of the wearer, and further, sound transmission can be realized based on the bone conduction technology.

The ear-hang part 2 is supported on the ear of a human body, the back-hang part 4 is positioned behind the brain, the weight of the bone conduction earphone is mainly balanced by the supporting force provided by the ear of the human body to the ear-hang part 2, and the supporting point of the bone conduction earphone is positioned on the ear-hang part 2. The ear-hook part 2 has a curved shape adapted to the contour of the human ear, and it is ensured that the ear-hook part 2 is not easily displaced when supported on the human ear.
