[0054] The third push rod 325 is movably connected to the first sound insulation cover 31 , the second sound insulation cover 321 and the third sound insulation cover 322 .

[0055] For further information, see Figure 1 to Figure 6 , the sound insulation adjustment component 33 includes:

[0056] An adjusting rod 331, one end of which is movably connected to the rotating rod 332, and the rotating rod 332 is symmetrically arranged with respect to the adjusting rod 331.

[0057] The transmission gear 333 is connected to the rotating rod 332 , and the transmission gear 333 is connected to the first push rod 323 .

[0058] For further information, see Figure 1 to Figure 6 The first sound insulation cover 31, the second sound insulation cover 321 and the third sound insulation cover 322 all adopt a hollow structure and sound insulation material.

[0059] For further information, see Figure 1 to Figure 6 The first push rod 323, the second push rod 324 and the third push rod 325 are arranged in parallel.

[0060] In this embodiment, in a strong noise environment, the first soundproof cover 31, the second soundproof cover 321 and the third soundproof cover 322 are stacked together, two second soundproof covers 321 and the third soundproof cover 322 are provided, and the second soundproof cover 321 and the third soundproof cover 322 are symmetrically arranged about the first soundproof cover 31. The first soundproof cover 31, the second soundproof cover 321 and the third soundproof cover 322 all adopt a hollow soundproof structure. The hollow first soundproof cover 31, the second soundproof cover 321 and the third soundproof cover 322 can reduce the weight of the headset. At the same time, when the three are stacked together, sound insulation and noise reduction are performed, and when the second soundproof cover 321 and the third soundproof cover 322 are opened, a ventilation effect is achieved;

[0061] The adjusting rod 331 is pressed downward, and the adjusting rod 331 drives the rotating rod 332 to move, and the rotating rod 332 drives the transmission gear 333 to rotate. Since the transmission gear 333 is fixedly connected to the first push rod 323, the first push rod 323 pushes the second soundproof cover 321 to move in an arc, so that the second soundproof cover 321 is unfolded, and the second soundproof cover 321 pushes the third push rod 325, and the third push rod 325 pushes the third soundproof cover 322 to move in an arc, so that the third soundproof cover 322 is unfolded. At the same time, when the second soundproof cover 321 and the third soundproof cover 322 are unfolded, the second push rod 324 can ensure that the second soundproof cover 321 and the third soundproof cover 322 have the same unfolding amplitude;

[0062] In a strong noise environment, the adjustment rod 331 is pulled up so that the two second sound insulation covers 321 are moved to be directly above the first sound insulation cover 31, and the two third sound insulation covers 322 are moved to be directly above the second sound insulation cover 321, thereby achieving a noise reduction effect.

[0063] The working principle of the present invention is:

[0064] An L-shaped anti-drop plate 5 is adopted, and the anti-drop plate 5 is an arc-shaped structure, so that the anti-drop plate 5 can better fit the ear, and the distance between the anti-drop plates 5 can be adjusted. Multiple groups of anti-drop plates 5 form a circle, and electronic components can be arranged in the earmuff adjustment mechanism 6. At the same time, the sound insulation mechanism 3 is arranged behind the earmuff adjustment mechanism 6 to prevent noise from entering the earphone;

[0065] Start the adjusting gear 621, the adjusting gear 621 drives the connecting gear 623 to rotate, and the connecting gear 623 drives the adjusting slot 631 to rotate. By setting the adjusting slot 631 to an arc shape, the adjusting slot 631 drives the limiting rod 632 to move. The limiting rod 632 pushes the sliding rod 633, and the sliding rod 633 moves in a straight line under the limiting action of the sliding groove 634. The sliding rod 633 drives the anti-slip plate 5 to move, and the anti-slip plate 5 moves outward to better engage the ear.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
