[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0028] The sound insulation earplugs on the market currently have memory sponge type and full-enclosed type. The two types of earplugs both belong to closed sound insulation structure, and have high sound insulation and noise reduction level. However, the noise reduction level that is too high limits the use scene, and wearing in the activity process will isolate the sound information (such as ring, normal call information) that needs to be obtained, and the memory sponge type earplug has the problems of wearing trouble and easy damage.

[0029] Therefore, the present application provides an earplug 100, which aims to make the noise reduction reach a relatively natural and quiet level, so that the user is comfortable and will not miss the useful external sound.

[0030] Reference Figures 1 to 3In an embodiment of the present application, the earplug 100 comprises:

[0031] The earplug body 1 is provided with a first sound passage 121 and a second sound passage 122 in communication with the first sound passage 121, and is further provided with an inlet sound port 123 in communication with the first sound passage 121 and an outlet sound port 124 in communication with the second sound passage 122, wherein the cross-sectional area of the first sound passage 121 is smaller than that of the second sound passage 122.

[0032] A first sound filter 2; and

[0033] A second sound filter 3, one of the first sound filter 2 and the second sound filter 3 is arranged at the inlet sound port 123, and the other of the first sound filter 2 and the second sound filter 3 is arranged at the outlet sound port 124.

[0034] In the embodiment, the earplug body 1 is the main part of the earplug 100, which is provided with the first sound passage 121 and the second sound passage 122, the inlet sound port 123 and the outlet sound port 124. One end of the first sound passage 121 is in communication with the second sound passage 122, and the other end of the first sound passage 121 is in communication with the outside through the inlet sound port 123. The end of the second sound passage 122 away from the first sound passage 121 is in communication with the ear canal of the user through the outlet sound port 124. The cross-sectional area of the first sound passage 121 is smaller than that of the second sound passage 122, the high-frequency sound is attenuated through the first sound passage 121, so that the sound transmitted into the second sound passage 122 is smoother and more natural, and the low-frequency and medium-frequency sound is attenuated through the second sound passage 122, so as to improve the clarity of the sound and make the sound transmitted into the ear canal more clear.

[0035] Further, the inlet sound port 123 of the earplug body 1 is provided with the first sound filter 2, and the outlet sound port 124 of the earplug body 1 is provided with the second sound filter 3. The first sound filter 2 can be realized by a first damping net, which prevents foreign matters from entering the sound passage and filters out part of the external noise, thereby reducing the interference of the noise on the ear canal. The second sound filter 3 can be realized by a second damping net, which further reduces the noise entering the ear canal and maintains the clarity of the sound.

[0036] The earplug 100 of the technical scheme of the utility model in actual use, external sound is transmitted to the sound filter piece of the sound inlet 123 by the sound inlet 123, and is sequentially transmitted to the first sound channel 121 and the second sound channel 122 after high-frequency attenuation of the sound filter piece of the sound inlet 123, after the first sound channel 121 and the second sound channel 122, high, medium and low frequencies all have different degrees of attenuation, and then the sound filter piece of the sound outlet 124 attenuates, so that the purpose of final noise reduction is achieved, and external sound can also enter the ear canal through the first sound channel 121 and the second sound channel 122, thereby solving the problem of discomfort of the ear caused by completely blocking external sound waves and missing useful external sound.

[0037] Referring to Figures 1 to 3 In an embodiment of the utility model, the earplug body 1 includes base 11 and shell 12, the base 11 is provided with through hole 111, the shell 12 is provided with first sound channel 121 and second sound channel 122, the part of shell 12 corresponding to first sound channel 121 is provided with in through hole 111 of base 11.

[0038] In this embodiment, the shell 12 is used to set the first sound channel 121 and the second sound channel 122. The base 11 is used to install the shell 12, and to limit the earplug body 1 when the earplug 100 is put into the ear canal, so as to avoid the whole earplug 100 from falling into the ear canal. On this basis, the part of the shell 12 corresponding to the first sound channel 121 is provided in the through hole 111 of the base 11, rather than all parts of the shell 12 being provided on the base 11, so as to reduce the volume of the earplug body 1, making the earplug 100 portable and easy to use.

[0039] Referring to Figures 1 to 3 In an embodiment of the utility model, the base 11 and the shell 12 are integrally formed, so as to improve the structural stability of the earplug body 1 and improve its drop resistance.

[0041] In this embodiment, one end of the ear cap 4 is in communication with the second sound channel 122, and the other end of the ear cap 4 is used to communicate with the inner ear. In this way, external sound can sequentially pass through the first sound channel 121 and the second sound channel 122 into the ear cap 4, and then enter the inner ear through the ear cap 4, thereby solving the problem of tinnitus and other discomfort caused by completely blocking external sound after wearing the ear cap 4 for a long time.

[0042] Optionally, the ear cap adopts a silica gel ear cap or a foam ear cap, the silica gel ear cap can be attached to the ear hole, so that sound can only enter the inner ear through the sound channel of the earplug body 1. The foam ear cap can be used as a spare part, which can better block external sound, and the user can use the silica gel ear cap or the foam ear cap according to the wearing comfort and the use scene.
