[0017] like Figure 1 Figure 2 Figure 3 As shown in the figure, a noise reduction earplug that does not enter the ear canal is shown according to an exemplary embodiment of the present invention. The structure is as follows: The earplug is cylindrical in shape, with an open front end and a closed rear end. The outer surface is smooth and can reflect noise. The inner surface is a cylindrical cavity 2, which can be loaded with a noise reduction component 4 through the open end. The earplugs are 10-12mm long and 10-12mm in diameter, with a cylindrical wall thickness of 0.5-2.5mm. 2-5 sizes are available to match the user's ear shape. They are made of medium-to-high-density noise-reducing materials, such as plastic and metal. The higher the material density, the better the high-frequency reflection blocking effect. Earplugs can be longer than 12mm for non-sleeping use, as being too long will cause discomfort when sleeping on the side.

[0018] The closed surface is densely covered with micro-through holes 1, with a hole diameter of 0.2~0.8mm, which can reduce noise and high-frequency noise; this earplug is suitable for reducing high-decibel noise and high-frequency noise in a high-decibel environment and can protect hearing.

[0019] Because human ears are different, 2-5 sizes need to be set, with the diameter difference between adjacent sizes being 0.5-1mm. For example: the diameters of 2 sizes of earplugs are 10mm and 11mm, or 10.5mm and 11.5mm; the diameters of 4 sizes of earplugs are 10mm, 10.5mm, 11mm, and 11.5mm.

[0020] like Figure 4 Figure 5 As shown in the figure, there is a diagram of another noise reduction earplug that does not enter the ear canal according to an exemplary embodiment of the present invention. The structure is as follows: The micro-through hole component 3 in the figure is obtained by splitting the micro-through hole surface. The processing cost is high when the hole diameter is too small and the material is thick. The whole is in the shape of a sheet or cylinder, with a thickness of 0.2~0.8mm, which is convenient for installation. It is made of metal laser perforation, such as stainless steel.

[0021] like Figure 6 Figure 7 As shown in the figure, there is a diagram of another noise reduction earplug that does not enter the ear canal according to an exemplary embodiment of the present invention. The structure is as follows: The earplug in the figure can be installed with the noise reduction component 4 from the open end to enhance noise reduction, and the rear closed surface has no micro-through holes to enhance noise reduction.

[0022] The noise reduction component 4 can be inserted into the cavity 2 to reduce noise, and is made of elastic polymer porous foam material or plastic material or silicone.

[0024] The plastic material 6 can be a silicone mud ear plug, which is rolled into a long strip 61 and then inserted into the cavity 2.

[0025] like Figure 9As shown in the figure, there is a cross-sectional view of another noise reduction earplug that does not enter the ear canal according to an exemplary embodiment of the present invention. The structure is as follows: The earplug in the figure is a sponge earplug inserted into the cavity 2, and the whole is in the shape of a bullet. When in use, the sponge earplug is rubbed out and the edge 52 of the sponge earplug rebounds to fill the ear canal opening, which can reduce noise.

[0026] like Figure 10 As shown in the figure, there is a cross-sectional view of another noise reduction earplug that does not enter the ear canal according to an exemplary embodiment of the present invention. The structure is as follows: The earplug in the figure is a silicone mud earplug inserted into the cavity 2, and the overall shape is bullet-shaped. When inserted into the ear during use, the earplug wall will press the front silicone mud edge 62 to deform and fill the ear canal opening, thereby completely sealing the ear canal opening and reducing noise.

[0027] like Figure 11 Figure 12 As shown in the figure, there is a diagram of another noise reduction earplug that does not enter the ear canal according to an exemplary embodiment of the present invention. The structure is as follows: The two ends of the earplug in the figure are closed, and the open end can be closed with a sealed round cover; the internal cavity can be vacuumed to below 7 to 0.1Pa, which will block the sound wave transmission path and thus reduce noise. An exhaust hole can be set in the center of the end face.
