DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0027] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings. Figures 1 to 4 The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings.
[0028] The sound filter earplug 100 provided by the utility model has small weight, high noise reduction level and good sound quality, and is not easily detached from the human body, so that noise in a construction site, a gym, a music place or a sleeping environment can be filtered out, thereby protecting hearing.
[0029] Reference is made to Figure 1 and Figure 2 The sound filter earplug 100 includes a support portion 13, a mounting portion 11 and a sound filter portion 15. The mounting portion 11 and the sound filter portion 15 are respectively mounted on the support portion 13.
[0030] The sound filter portion 15 includes a first sound filter portion 151 and a second sound filter portion 153. The first sound filter portion 151 is located between the support portion 13 and the mounting portion 11 and is connected with both. The mounting portion 11 is used for insertion into the ear. The support portion 13 is hollow inside to form a receiving space 130 for receiving the second sound filter portion 153 of the sound filter portion 15. The sound filter portion 15 is combined by a plurality of different sound filtering pieces and dustproof pieces, thereby forming the sound filter earplug 100 with high noise reduction level, sound quality and high definition.
[0031] The support portion 13 includes an integrally formed connecting portion 131 and a protruding portion 133. The connecting portion 131 is in a heart-shaped structure, one side of which is used for receiving the helix foot of the human body, and the other side is used for abutting against the inner wall of the ear, so that the earplug is not pressed by the ear and can be stably supported on the ear. The protruding portion 133 extends perpendicularly from one end of the connecting portion 131 and is connected with the first sound filter portion 151.
[0032] Specifically, the middle of the connecting part 131 is concave and forms a concave part 1310. For aesthetic design, the connecting part 131 as a whole presents a "moon shape" or a "heart shape", and the middle of the "moon shape" or the "heart shape" is the concave part 1310. Since most human ears have an ear bone at the helix foot, one side wall of the concave part 1310 in the middle of the connecting part 131 can accommodate the ear bone on the helix foot, so that the human body will not be pressed by the ear bone when the earplug is worn and rested. The position corresponding to the protruding part 133 of the connecting part 131 is provided with a supporting tube 1311. One end of the supporting tube 1311 is fixed to the bottom of the connecting part 131, and the other end is connected to the second sound filtering part 153, so that the second sound filtering part 153 is stably installed in the supporting part 13.
[0033] Importantly, the inside of the supporting tube 1311 is hollow and forms an air pipe, which not only balances the frequency of the sound transmitted into the ear to ensure the clarity of the sound transmitted into the ear, but also balances the pressure inside and outside the ear, so that there is enough air in the ear to avoid discomfort caused by long-term wearing.
[0034] The protruding part 133 extends vertically from one end of the concave part 1310 and is in a cylindrical shape, and the other end is provided with an opening for connecting the first sound filtering part 151. The cross-sectional area of the protruding part 133 gradually decreases from the end close to the connecting part 131 to the end away from the connecting part 131 to equal the cross-sectional area of the first sound filtering part 151. The inside of the protruding part 133 is hollow and forms a receiving space 130 for accommodating the second sound filtering part 153.
[0035] Referring to Figure 2 and Figure 3 , the mounting part 11 is in a cylindrical shape, and both ends are provided with openings, including a first opening 111 and a second opening 113. The first opening 111 and the second opening 113 are connected to each other, and the first opening 111 is recessed inward from the end of the mounting part 11 away from the protruding part 133, so that the cross-sectional area of the first opening 111 is smaller than that of the second opening 113, and the cross-sections of the first opening 111 and the second opening 113 present a stepped shape. The first opening 111 is used for inserting into the inside of the ear, and the second opening 113 is used for accommodating the first sound filtering part 151, part of the protruding part 133 and part of the second sound filtering part 153, so that the first sound filtering part 151 and the second sound filtering part 153 are in communication with each other, and the sound filtering part 15 will not be damp in any humidity environment.
[0036] The sound filter 15 is composed of sound filter materials with different materials and shapes, which includes a first sound filter 151 and a second sound filter 153.

It can be understood that the first dustproof net 1511 is usually made of light metal materials such as stainless steel, aluminum, nickel, etc.
[0039] Similarly, the first sound filter net 1513 is also a disc, and its cross-sectional area is equal to that of the first dustproof net 1511. The first sound filter net 1513 is located in the second opening 113 close to one side of the protruding part 133, can effectively filter noise of a specific frequency, enhance the sound filtering performance, and also protect the second sound filter 153 from dust and sundries. In this embodiment, the first sound filter net 1513 is composed of high-density foam, polyester fiber or other synthetic materials through multi-layer design, which can provide better sound absorption effect, form an acoustic level professional sound filter net, and the material is light and will not cause compression to the ear.
[0040] The second sound filter 153 includes a sound tuning net 1533, a sound tuning part 1531 and a second sound filter net 1535. The sound tuning part 1531 is accommodated in the sound tuning net 1533, and is connected to the first sound filter net 1513 at one end and to the second sound filter net 1535 at the other end, and the other end of the second sound filter net 1535 is connected to the support pipe 1311, so that the second sound filter 153 is stably arranged in the accommodation space 130.
[0041] The tuning net 1533 and the tuning part 1531 are both tubular, have the same height, and have openings at both ends. The outer diameter of the tuning net 1533 is slightly larger than the inner diameter of the tuning part 1531, so that the tuning part 1531 is accommodated in the tuning net 1533. One end of the tuning net 1533 and the tuning part 1531 is connected to the first sound filtering net 1513, and the other end is connected to the second sound filtering net 1535. When the tuning net 1533 and the tuning part 1531 are accommodated in the accommodation space 130, the end of the tuning net 1533 and the tuning part 1531 away from the support tube 1311 is flush with the opening end surface of the protruding part 133.
[0042] The tuning part 1531 has a certain height, has strong noise attenuation capability, and as a filtering layer of the earplug, can block external noise from entering the ear canal, while also providing certain air permeability to maintain the comfort of the ear canal.
