[0025] Connecting structure 15, the connecting structure 15 includes a fixed block 5, a slider 6, a connecting rod 7, a movable plate 8 and an insertion block 9. The outer surface of the slider 6 is slidably connected to the fixed block 5. One end of the connecting rod 7 is fixedly connected to the side surface of the slider 6. The end of the connecting rod 7 away from the slider 6 is fixedly connected to the movable plate 8. The side surface of the insertion block 9 is fixedly connected to the movable plate 8. A positioning groove 10 is provided on the fixed block 5. The outer surfaces of the first steel sheet 1 and the second steel sheet 2 are both movably connected to the positioning groove 10. The side surface of the movable plate 8 is in contact with the second steel sheet 2. The outer surface of the insertion block 9 is movably connected to the first fixing groove 11. The outer surface of the insertion block 9 is movably connected to the second fixing groove 12. A spring 13 is slidably sleeved on the outer surface of the connecting rod 7. One end of the spring 13 is fixedly connected to the side surface of the slider 6. The end of the spring 13 away from the slider 6 is fixedly connected to the side inner wall of the fixed block 5. The outer surface of the connecting rod 7 is slidably connected to the fixed block 5. The side surface of the movable plate 8 is in contact with the fixed block 5.

[0026] Working principle: When the first steel sheet 1 breaks, under the action of the second steel sheet 2, the adjustment mechanism of the earphone can be used normally. When the second steel sheet 2 breaks, under the action of the first steel sheet 1, the adjustment mechanism of the earphone can be used normally. When both the first steel sheet 1 and the second steel sheet 2 break and need to be replaced, by pulling the movable plate 8, the moving movable plate 8 can drive the slider 6 and the connecting rod 7 to move. At the same time, during the movement of the slider 6, it will gradually squeeze the spring 13 on the inner wall of the fixed block 5, so that the spring 13 is in a taut state. And the moving movable plate 8 will drive the insertion block 9 to move. When the moving insertion block 9 disengages from the first fixing groove 11 and the second fixing groove 12 and does not affect the removal of the first steel sheet 1 and the second steel sheet 2 from the positioning groove 10, lift the first steel sheet 1 and the second steel sheet 2, so that the first steel sheet 1 and the second steel sheet 2 can be removed from the positioning groove 10. Then pull the first steel sheet 1 and the second steel sheet 2, and draw out the first steel sheet 1 and the second steel sheet 2 from the gap between the insertion block 9 and the fixed block 5. Then place the new first steel sheet 1 and second steel sheet 2 at the position corresponding to the positioning groove 10 through the gap between the insertion block 9 and the fixed block 5, and insert the first steel sheet 1 and the second steel sheet 2 into the positioning groove 10, so that the insertion block 9 corresponds to the first fixing groove 11 and the second fixing groove 12. Then release the pulling of the movable plate 8, and further make the spring 13 rebound without being restricted by the pulling force. The rebounding spring 13 can drive the slider 6, the connecting rod 7, the movable plate 8 and the insertion block 9 to move. When the moving insertion block 9 is inserted into the first fixing groove 11 and the second fixing groove 12, the fixing of the first steel sheet 1 and the second steel sheet 2 is completed. Then, through the first docking holes 3 and the second docking holes 4 on the first steel sheet 1 and the second steel sheet 2, the first steel sheet 1 and the second steel sheet 2 can be connected to the sliding arm housing.
[0027] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
