[0024] In the embodiment, the bone conduction assembly 5 and the cartridge member 3 extend in the opposite first direction and second direction with the ear hook member 2 as the center; in the above design, the ear hook member 2 is used as the main fixing structure to fit the contour of the ear, and the bone conduction assembly can extend to the malar region or the temporal region regardless of the wearing mode, and the two regions have good resonance effect; the cartridge member 3 is arranged in the direction of the rear hanger 1 to enable the rear hanger 1 to surround the back of the user's head.

[0026] In this embodiment, the bin body 3 is movably connected with the ear hook 2, and the extension direction of the bin body 3 can be adjusted from the second direction to the first direction. The ear hook 2 and the bin body 3 in the second direction together form a wearing structure that exerts force on the back of the user's ear. It is not difficult to understand that by the above design, in the case of wearing the ear hook, the vibrator assembly, the ear hook 2 and the bin body 3 form a "C" shape, which can better fit the root of the ear back and achieve more stable hanging wearing. In a specific scheme, the bin body 3 and the ear hook 2 are connected through a rotating shaft, so that the bin body 3 is rotated from the first direction to the second direction. The corresponding rotating shaft structure is a first column and a second column that can rotate relative to each other. The opposite ends of the first column and the second column are connected to the bin body 3 and the ear hook 2 respectively, thereby realizing the rotation to change the direction of the bin body 3. In a further scheme, the rotating shaft is a damping shaft, which can stop at a preset angle, thereby helping the user to adjust the wearing structure that better fits the contour of the ear. As an important improvement, on the basis of the above-mentioned embodiment, please refer to the attached Figures 3-4, the ear hook piece 2 and the bin body piece 3 are further provided with a flexible piece 4, one end of the flexible piece 4 is connected with the ear hook piece 2 through a rotating shaft, and the other end is connected with the bin body piece 3; by the above design, the flexible piece 4 can further make the bin body piece 3 present the expected swing range, further increase the flexibility of wearing, and better wearing experience is provided for the user.
