[0030] In order to improve the feel of adjustment, an elastic convex strip 21 is provided on one side of the toggle switch 2, and a limit convex point 22 is provided on the elastic convex strip 21. Two limit slots 51 are provided on the side wall of the limit slide 5 near the elastic convex strip 21, and the limit convex point 22 can be respectively engaged with the two limit slots 51. In the process of pushing the toggle switch 2 to slide in the limit slide 5, the limit slide 5 will squeeze the limit convex point 22, so that the elastic convex strip 21 undergoes a certain elastic deformation; when the limit convex point 22 is aligned with one of the limit slots 51, the elastic convex strip 21 will elastically recover, so that the limit convex point 22 is engaged in the limit slot 51, and the user can hear a "click" sound, indicating that the adjustment has been in place at this time, and the accuracy of the adjustment is improved through the user's hearing and feel, and the user's experience is enhanced. The states in which the limit protrusion 22 is engaged with the two limit slots 51 correspond to the states in which the sound receiving hole 4 is opened or blocked, respectively; specifically, in the process of pushing the toggle switch 2 to block the sound receiving hole 4, when the limit protrusion 22 is engaged with the limit slot 51 on the side close to the sound receiving hole 4, it means that the toggle switch 2 has completely blocked the sound receiving hole 4; in the process of pushing the toggle switch 2 to open the sound receiving hole 4, when the limit protrusion 22 is engaged with the limit slot 51 on the side away from the sound receiving hole 4, it means that the toggle switch 2 has completely opened the sound receiving hole 4.

[0031] A first dustproof net 10 is provided in the limiting slide groove 5, and the first dustproof net covers the sound receiving hole 4. By providing the first dustproof net 10, foreign matter such as dust can be reduced from entering the sound receiving channel 3 through the sound receiving hole 4, thereby ensuring the cleanliness of the inside of the earplug.

[0032] A sound-blocking mesh 11 is provided on the upper end surface of the first dustproof net 10, and a sound hole 12 is provided at the corresponding position between the sound-blocking mesh 11 and the sound receiving hole 4, so that external sound can enter the sound receiving hole 4 through the sound-blocking mesh 11. The sound-blocking mesh 11 can absorb a part of the sound entering the corresponding position of the sound receiving hole 4, so that the sound receiving hole 4 can still retain a certain noise reduction ability when it is open. In this embodiment, the sound-blocking mesh 11 is a mutually bonded PET transparent high-temperature resistant film and memory foam; in other embodiments, the sound-blocking mesh 11 can also be made of other sound-absorbing materials.

[0033] In order to facilitate the adjustable earplug to be hung on the user's ear, an ear cap 13 is provided on the end of the earplug body 1 away from the toggle switch 2, the ear cap 13 is fixedly connected to the earplug body 1, and a sound outlet hole 14 is provided on the ear cap 13, and the sound outlet hole 14 is connected to the sound receiving channel 3. When in use, the user can insert the ear cap 13 into the ear canal, so that the adjustable noise reduction earplug can be hung on the user's ear.

[0034] A second dustproof net 15 is provided inside the ear cap 13, and the second dustproof net 15 covers the sound outlet 14. The second dustproof net 15 can reduce dust and other foreign matter from entering the sound receiving channel 3 through the sound outlet 14, thereby ensuring the cleanliness of the inside of the earplug.

[0036] Working principle:

[0037] When the adjustable noise reduction earplug is hung on the ear, the ear cap 13 only needs to be inserted into the ear canal to hang the adjustable noise reduction earplug on the ear and fix it.

[0038] During use, if a stronger noise reduction performance is required, the user can push the decorative cover 9 to move in the direction close to the sound receiving hole 4, and the decorative cover 9 drives the toggle switch 2 to slide in the limiting slide groove 5, and the limiting slide groove 5 will squeeze the limiting protrusion 22, so that the elastic convex strip 21 undergoes a certain elastic deformation; when the limiting protrusion 22 is aligned with the limiting card slot 51 on the side close to the sound receiving hole 4, the limiting protrusion 22 will automatically snap into the limiting card slot 51, and the user can hear a "click" sound, indicating that the toggle switch 2 has completely blocked the sound receiving hole 4 at this time, and the user can get a stronger noise reduction experience. If the noise reduction performance needs to be reduced, the decorative cover 9 can be pushed to move away from the sound receiving hole 4. The decorative cover 9 drives the toggle switch 2 to slide in the limiting slide groove 5. The limiting slide groove 5 will squeeze the limiting protrusion 22, causing the elastic convex strip 21 to undergo a certain elastic deformation; when the limiting protrusion 22 is aligned with the limiting card slot 51 on the side away from the sound receiving hole 4, the limiting protrusion 22 will automatically snap into the limiting card slot 51, and the user can hear a "click" sound, indicating that the toggle switch 2 has completely opened the sound receiving hole 4; external sound can enter the sound receiving hole 4 through the sound resistance mesh 11, and then enter the sound receiving channel 3, and then pass through the sound outlet hole 14 into the user's ear, so that the user can be aware of the external ambient sound.
