[0002] With the ubiquity of mobile devices, earphones have become an essential accessory in our daily lives. Silicone and sponge earplugs are popular among users for their softness, comfort, and excellent sound insulation. While there are many different types of earphone covers on the market, they are generally made from silicone and sponge. Earphone tubes come in three textures: rubber, sponge, and silicone. However, due to their acoustic properties, these materials inevitably absorb some of the frequencies transmitted from the earphone outlet, resulting in sound loss. Furthermore, the external structure of some earphone covers can affect the quality and effectiveness of sound transmission, hindering optimal sound quality. Utility Model Content

[0008] In one embodiment, a mounting ring located below the clamping ring is provided on the inner wall surface of the axial through hole, and the inner core of the metal conduit has a mounting portion provided in the mounting ring, and the mounting portion is connected to the buffer washer.
[0009] In one embodiment, the inner core of the metal conduit is made of stainless steel, brass, or aluminum alloy.
[0010] In one embodiment, the buffer gasket is made of silicone or rubber.
[0011] In one embodiment, the earplug body is made of silicone.
[0012] In addition, the present invention also provides an earphone, which includes an earphone body and the above-mentioned earplug arranged on the earphone body.
[0013] In the technical solution of this utility model, the earplug comprises an earplug body and a metal conduit inner core. The earplug body includes an axial through-hole, and the metal conduit inner core is disposed within the axial through-hole and is clamped and connected to the inner wall surface of the axial through-hole. Therefore, in this technical solution, by disposing the metal conduit inner core within the earplug body, it assists in sound transmission, achieving a sound transmission effect superior to that of silicone, sponge, and rubber, and effectively reducing sound loss.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0021] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0022] Moreover, the technical solutions between the various embodiments of the present invention may be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0023] The present invention provides an earplug. The earplug provided in the present application can be used with an earphone as an integrated earphone, or can be used in combination with an earphone as a split earplug. Since the earphone adopts all the technical solutions of all the following embodiments, it has at least all the beneficial effects brought about by the technical solutions of the following embodiments, which will not be described one by one here.
[0024] like Figure 1-2 As shown, the earplug provided by the embodiment of the present invention includes an earplug body 10 and a metal tube core 20, the earplug body 10 includes an axial through hole 11, the metal tube core 20 is arranged in the axial through hole 11 and is clamped and connected with the inner wall surface of the axial through hole 11, the axial through hole 11 includes a sound outlet hole 111 and a docking hole 112 arranged oppositely, and the metal tube core 20 is arranged at the sound outlet hole 111.
[0025] In this embodiment, a metal conduit core 20 is provided inside the earplug body 10 to assist in sound transmission, thereby achieving a better sound transmission effect than silicone, sponge, and rubber, and effectively reducing sound loss.
[0026] The earplug also includes a cushioning washer 30, which is attached to the inner wall of the axial through-hole 11 and to the lower end of the metal conduit core 20. In this embodiment, the cushioning washer 30 prevents damage to the earplug body 10 from colliding with the metal conduit core 20 when docking with an earphone. Specifically, the distance from the cushioning washer 30 to the axis of the axial through-hole 11 is less than the distance from the metal conduit core 20 to the axis of the circumferential through-hole.
[0027] Please refer to Figure 2 The inner wall of the axial through hole 11 is provided with a plurality of spaced-apart snap rings 12, and the outer wall of the metal conduit core 20 has a plurality of retaining portions 21, which can be retained within the snap rings 12. In this embodiment, the metal conduit core 20 and the earplug body 10 can be fixed by bonding.
[0028] Meanwhile, a mounting ring 13 is provided on the inner wall of the axial through hole 11, positioned below the clamping ring 12. The metal conduit inner core 20 has a mounting portion 22 disposed within the mounting ring 13, which is connected to the buffer washer 30. In this embodiment, the axial through hole 11 is provided with a stepped portion 14 positioned below the mounting ring 13. When the mounting portion 22 is also disposed within the mounting ring 13, an L-shaped groove is formed below the mounting portion 22. The L-shaped groove and the stepped portion 14 cooperate to mount the buffer washer 30. Similarly, the buffer washer 30 can also be mounted by adhesive bonding.
[0029] In the above embodiment, the metal conduit core 20 can be made of stainless steel, brass, aluminum alloy, etc. The cushioning ring 30 is made of silicone or rubber. The earplug body 10 is made of silicone. Silicone earplug bodies 10 are more comfortable, skin-friendly, soft, and flexible, while also providing sound insulation.
