Description

Technical Field

[0001] The utility model relates to the technical field of earphone accessories, and specifically relates to a deformable earplug for an earphone. Background Technique

[0002] Most of the earplugs on the current market are made of silicone or sponge materials with a fixed shape. The design of these earplugs cannot be adjusted according to the individual differences of users' ear canals. Since the shapes and sizes of everyone's ear canals are different, using earplugs with a fixed shape cannot meet the needs of all users, resulting in discomfort during long-term wearing. In addition, the fixed-shaped earplugs may not fit perfectly into the ear canal during wearing, affecting the sound sealing and sound quality.

[0003] Although some deformable earplug products have emerged on the market, by using thermoplastic materials or plastic wax materials, users need to go for private customization, which is expensive. In addition, the current deformable earplugs usually need to be used in conjunction with specific models of earphones, restricting their versatility and flexibility. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a deformable earplug for an earphone, which solves the problems put forward in the above background technique.

[0006] (II) Technical Solutions

[0007] To achieve the above objectives, the utility model is realized through the following technical solutions: A deformable earplug for an earphone includes an earplug main body and a fixed core. A through hole that is open in the middle is provided in the middle of the fixed core. A plurality of clamping grooves are provided on the outer side of the fixed core. The earplug main body is clamped in the clamping grooves. One end of the through hole is provided with an interface, and the interface and the through hole are of an integral structure. The earplug main body is selected from thermoplastic eucommia rubber elastomer.

[0008] Preferably, the interface includes a limiting groove and a sliding groove. The limiting groove is recessed inside the fixed core. The sliding groove is perpendicular to the limiting groove and is connected to the limiting groove.

[0009] Preferably, the depth of the limiting groove is greater than or equal to the depth of the sliding groove.

[0010] Preferably, in the direction of the limiting groove along the sliding groove to the end of the through hole, the diameter of the through hole gradually increases, so that the inner diameter plane of the through hole has a gradient.

[0011] Preferably, the fixed core is selected from silicone material.

[0012] (III) Beneficial Effects

[0013] The present utility model provides a deformable earplug for headphones, with the following beneficial effects:

[0014] 1. For the deformable earplug for headphones provided in this solution, the earplug body is selected from thermoplastic eucommia rubber elastomer, which softens upon heating and hardens after cooling to room temperature. The shape of the earplug can be freely adjusted according to the needs of users, providing better sound quality and wearing experience. In addition, the thermoplastic eucommia rubber elastomer in this solution has excellent abrasion resistance and a long service life.

[0015] 2. For the deformable earplug for headphones provided in this solution, an interface is provided on the through hole. This interface can adapt to different headphone models on the market. Without customization, users can enjoy a perfect wearing experience, significantly reducing the cost and inconvenience when purchasing different earplugs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] An embodiment of the present utility model provides a deformable earplug for headphones. As Figure 1-2 shown, it includes an earplug body 1 and a fixed core body 2. A through hole 21 that is open in the middle is provided in the middle of the fixed core body 2. A plurality of clamping grooves 22 are provided on the outer side of the fixed core body 2. The earplug body 1 is provided with grooves matching the clamping grooves 22, so that the earplug body 1 can be fixed in the clamping grooves 22. One end of the through hole 21 is provided with an interface 23, and the interface 23 and the through hole 21 are of an integral structure. Among them, the interface 23 can be adaptively connected to headphones on the market. The earplug body 1 is selected from thermoplastic eucommia rubber elastomer. Before using the earplug, it is first placed in hot water, taken out after softening, cooled to an appropriate temperature and then put into the external auditory canal for shaping. After cooling to room temperature and the earplug body hardening, the earplug is connected to the headphone interface.

[0022] In a specific embodiment, such as Figure 3 As shown, the interface 23 includes a limiting groove 231 and a sliding groove 232. The limiting groove 231 is recessed into the interior of the fixed core 2. The sliding groove 232 is perpendicular to the limiting groove 231 and is connected to the limiting groove 231. In this embodiment, the connection hole of the earphone slides into the limiting groove 231 through the sliding groove 232 for limiting and fixing.

[0023] In a specific embodiment, the depth of the limiting groove 231 is greater than or equal to the depth of the sliding groove 232, which can make the connection hole of the earphone be clamped in the limiting groove 231 and improve the stability of the connection between the earplug and the earphone.

[0024] In a specific embodiment, along the direction of the limiting groove 231 from the sliding groove 232 to the end of the through hole 21, the diameter of the through hole 21 gradually increases, so that the inner diameter plane of the through hole 21 has a gradient. By providing an inclined surface inside the through hole 21, earphones of different models can be adapted, and it is more convenient to slide into the limiting groove 231 along the sliding groove 232.

[0025] In a specific embodiment, the fixed core 2 is selected from silica gel materials. It should be noted that the silica gel material in the present utility model is a hard silica gel material. On the one hand, the fixed core 2 can serve as a support for the earplug main body 1. On the other hand, the fixed core 2 can achieve a stable connection with the earphone interface.

[0026] According to Figure 1 and Figure 4 As shown, since the earplug main body 1 of the present utility model adopts thermoplastic eucommia rubber elastomer, before wearing, the earplug is placed in hot water to soften the earplug main body 1, taken out and cooled to an appropriate temperature, then stuffed into the user's ear for shaping. After taking out, the earplug main body 1 hardens and takes shape at room temperature. Different-shaped earplugs can be obtained, and then the earplug is connected to the earphone connector, and an earphone that conforms to the shape of the user's ear canal can be customized, improving the sound quality and wearing experience.

[0027] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
