[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this utility model discloses a sleep headphone with multiple noise reduction effects, comprising a headphone body 1. The headphone body 1 includes a lower headphone cover 2 and a top headphone cover 3 that matches and fits the lower headphone cover 2. An ear cap 4 is provided on the lower headphone cover 2 at the end away from the top headphone cover 3, and a mesh fabric 5 is provided at the connection between the lower headphone cover 2 and the ear cap 4. The headphone body 1 has an adjustable noise reduction adjustment structure 6 inside, which includes a positioning block 7 located on the inner wall of the top headphone cover 3 and open at one end. An EVA plate 8 is provided on the side of the positioning block 7 facing the lower headphone cover 2, and a through hole is opened in the middle of the EVA plate 8. Airflow holes communicating with the through hole are provided on the lower headphone cover 2, the ear cap 4, and the mesh fabric 5. A conical channel 9 communicating with the inner cavity of the positioning block 7 is provided on one side of the positioning block 7. A sliding arm 10 is slidably provided inside the top headphone cover 3, and one end of the sliding arm 10 is provided with a... A conical column 11 matches the conical channel 9. A sealing ring 12 is fitted at the base of the conical column 11. A guide sliding hole 13 is opened in the middle of the headphone cover 3. A connecting column 14 extending out of the guide sliding hole 13 is provided on the sliding arm 10. A push button 15 is provided at the outer end of the connecting column 14. The sliding arm 10 is connected to the push button 15 through the connecting column 14. The sliding arm 10 is provided with the conical column 11 and the sealing ring 12. Pushing the push button 15 causes the sliding arm 10 to move through the connecting column 14, so that the conical column 11 at the end of the sliding arm 10 is inserted into the conical channel 9. The sealing ring 12 can seal the airflow in the ear canal, producing a noise reduction effect. Pushing the push button 15 back opens the airflow in the ear canal, producing another noise reduction effect. By moving the push button 15, the headphone produces different airflows to achieve different noise reduction effects. Two noise reduction effects can be achieved, improving the applicability.

[0029] Specifically, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a positioning ring 16 is provided at one end of the sliding arm 10 away from the conical column 11. A positioning column 17 is provided inside the positioning ring 16. A positioning bead 18 is provided at one end of the positioning column 17. The inner wall of the lower cover 2 of the earphone is provided with two positioning grooves 19 that are adapted to the positioning bead 18. By adjusting the positioning bead 18 into one of the positioning grooves 19, the positioning groove 19 can limit the positioning bead 18, thereby adjusting the noise reduction mode according to the usage environment.

[0030] The inner wall of the headphone cover 3 is provided with two guide plates 20, and both sides of the sliding arm 10 are provided with guide slide plates 21 that match the guide plates 20 and slide. When the sliding arm 10 moves, the guide slide plates 21 move along the two guide plates 20, which improves the stability of the movement of the sliding arm 10. The inner wall of the headphone cover 2 is provided with a pressing plate 37, which can press the sliding arm 10.

[0031] The guide slide plate 21 has a limiting protrusion 22 on its outer end wall, and the guide plate 20 has two limiting grooves 23 that are adapted to the limiting protrusion 22 on one side. The limiting protrusion 22 and the two limiting grooves 23 are adapted to each other, and two noise reduction modes can be adjusted according to the usage environment, so that the stability after adjustment is higher.

[0032] The connecting post 14 has an internal threaded slot 24 at its end, and a positioning connecting tube 25 is provided in the middle of the sliding arm 10. A locking screw 26 is threaded through the positioning connecting tube 25 and connected to the internal threaded slot 24. When connecting the sliding arm 10 and the push button 15, the connecting post 14 on the push button 15 is inserted into the positioning connecting tube 25 on the sliding arm 10, and then the locking screw 26 is passed through the positioning connecting tube 25 and threadedly connected to the internal threaded slot 24 of the connecting post 14, so that the sliding arm 10 and the push button 15 can be connected.

[0033] The inner wall of the push button 15 is symmetrically provided with two limiting slides 27, and the headphone cover 3 is provided with a guide groove 28 located at the guide slide hole 13 and matching the two limiting slides 27. When the push button 15 moves, the two limiting slides 27 move along the guide groove 28, which improves the stability of the push button 15.

[0034] The lower cover 2 of the earphone has a locking groove 29 on its inner wall edge, and the upper cover 3 of the earphone has a locking strip 30 that matches the locking groove 29 on its edge edge. Each corner of the inner wall of the lower cover 2 of the earphone has a positioning rod 31, and the inner wall of the upper cover 3 of the earphone has a positioning tube 32 that matches the positioning rod 31. Both sides of the upper cover 3 of the earphone have elastic blocks 33, and the ends of the elastic blocks 33 have elastic protrusions. The inner wall of the lower cover 2 of the earphone has an elastic groove 34 that matches the elastic protrusions. After connecting the upper cover 3 of the earphone, the sliding arm 10 and the push button 15, the lower cover 2 of the earphone is closed onto the upper cover 3 of the earphone. The locking strip 30 matches and engages with the locking groove 31. At the same time, the positioning rod 31 matches and engages with the positioning tube 32. Then, the elastic blocks 33 are pressed into the interior of the elastic groove 34, so that the lower cover 2 and the upper cover 3 of the earphone can be closed.

[0035] One end of the positioning connecting tube 25 is provided with a limiting notch 35, and the outer wall of the internal threaded slot 24 is provided with a limiting anti-rotation block 36 that matches the limiting notch 35. After the connecting column 14 is inserted into the positioning connecting tube 25 on the sliding arm 10, the limiting notch 35 matches the limiting anti-rotation block 36, which can prevent the connecting column 14 and the positioning connecting tube 25 from rotating relative to each other.

[0036] When in operation, this type of sleep earphone with multiple noise reduction effects has a sliding arm 10 connected to a push button 15 via a connecting post 14. The sliding arm 10 is equipped with a conical post 11 and a sealing ring 12. Pushing the push button 15 causes the sliding arm 10 to move via the connecting post 14, so that the conical post 11 at the end of the sliding arm 10 is inserted into the conical channel 9. The sealing ring 12 can seal the airflow in the ear canal, producing a noise reduction effect. Pushing the push button 15 back opens the airflow in the ear canal, producing another noise reduction effect. By moving the push button 15, different airflows are generated in the earphone to achieve different noise reduction effects, thus achieving two noise reduction effects and improving applicability.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
