Description

Technical Field

[0001] The utility model relates to the technical field of earphone products, in particular to a noise-reducing earplug that is more comfortable to wear. Background Art

[0002] Earphones are a commonly used electronic product. Since the original earphones generally use a hard shell, wearing them for a long time can easily cause ear discomfort. For this reason, people have invented various earplugs to be used with earphones. Since earplugs are generally made of soft rubber, such as silicone, they can reduce the discomfort when worn. For example, the Chinese utility model patent application CN219999550U filed by the applicant discloses a noise-reducing earplug that can receive external sound and maintain sound quality. However, the existing earplugs of this type are not designed with a deformation avoidance structure (solid structure) inside the earmuffs or the deformation avoidance structure is unreasonably designed. For example, the deformation part has a small range of deformation due to the small cavity. This causes discomfort or even pain in the ears after long-term wearing of the earplugs, thereby affecting the user experience. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a noise reduction earplug with a more reasonable structural design, which can generate sufficient deformation when worn to better fit the ear and make it more comfortable to wear.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a noise reduction earplug that is more comfortable to wear, comprising an earplug main body and an earmuff, the earmuff being connected to a fixing portion of the earplug main body, the earplug main body having a sound inlet hole, the earmuff being made of a silicone material and having a sound outlet hole, the sound outlet hole being connected to the sound inlet hole, characterized in that: a fixing seat is provided inside the earmuff, the outer wall of the fixing seat and the inner wall of the earmuff are spaced a distance from each other to form a cavity; a connecting portion is provided at the bottom of the earmuff protruding toward the fixing seat, the outer diameter of the connecting portion is smaller than the outer diameter of the fixing seat, so that the connecting portion forms an inwardly contracted recessed structure relative to the fixing seat; the bottom of the fixing seat is contracted inwardly to form a recessed portion, the recessed portion is connected to the connecting portion, so that the fixing seat is upright inside the earmuff, and a deformation cavity is formed inside the earmuff by the inward contraction structure of the connecting portion and the recessed portion, the deformation cavity is located at the bottom of the cavity and is connected to the cavity.

[0005] Furthermore, the recessed portion is contracted and tilted inwardly, so that an inclined connecting portion is formed between the fixing seat and the connecting portion, and the deformation cavity cooperates with the recessed portion to form a structure that tilts inwardly and deeply relative to the fixing seat.

[0006] Furthermore, the fixing seat, the recessed portion, the connecting portion and the earmuff are an integrated structure and are made by one-piece molding.

[0007] Furthermore, the sound outlet hole passes through the connecting portion and the fixing seat from the bottom of the earmuff, and the hole diameter of the sound outlet hole in the connecting portion is smaller than the hole diameter of the sound outlet hole in the fixing seat.

[0008] Furthermore, a buckle portion is provided in the fixing seat, and a buckle groove is provided on the fixing portion. After the fixing portion is inserted into the fixing seat, the buckle portion is buckled into the buckle groove to fix the earmuff and the earplug body together.

[0009] Furthermore, the height of the fixing seat is lower than the height of the earmuff, so that the fixing seat does not protrude from the rear end of the earmuff.

[0010] Furthermore, the surface of the buckle portion has a portion that is inclined inwardly, and the end of the fixing portion also has a portion that is inclined inwardly and contracted. This structure can make the assembly operation smoother.

[0011] The present invention connects the fixing base to the earmuff by arranging an inwardly contracted recessed portion and a connecting portion inside the earmuff, thereby forming an inwardly deep recessed deformation cavity. This significantly increases the deformable space, making the earmuff softer and easier to deform, so that it can better fit the ear and is more ergonomic. Long-term wearing of the earplugs is more comfortable and will not cause ear discomfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In this embodiment, refer to Figure 1-Figure 4The noise reduction earplugs that are more comfortable to wear include an earplug body 1 and an earmuff 2. The earmuff 2 is connected to a fixing portion 11 of the earplug body 1. The earplug body 1 has a sound inlet. The earmuff 2 is made of silicone material and has a sound outlet 5. The sound outlet 5 is connected to the sound inlet. A fixing seat 3 is provided inside the earmuff 2. The outer wall of the fixing seat 3 and the inner wall of the earmuff 2 are separated from each other by a distance to form a cavity. A connecting portion 21 protruding toward the fixing seat 3 is provided at the bottom of the earmuff 2. The outer diameter of the connecting portion 21 is smaller than that of the fixing seat 3. The outer diameter of the connecting portion 21 forms an inwardly contracted recessed structure relative to the fixing base 3; the bottom of the fixing base 3 contracts inwardly to form a recessed portion 31, which is connected to the connecting portion 21 so that the fixing base 3 is upright inside the earmuff 2. The inward contraction structure of the connecting portion 21 and the recessed portion 31 forms a deformation cavity 4 inside the earmuff 2. The deformation cavity 4 is located at the bottom of the cavity and communicates with the cavity. Due to the existence of the deformation cavity 4, the part of the earmuff 2 corresponding to the deformation cavity 4 is softer and more easily deformed.

[0018] The recessed portion 31 is contracted and tilted inwardly, so as to form an inclined connecting portion between the fixing seat 3 and the connecting portion 21 , and the deformation cavity 4 cooperates with the recessed portion 31 to form a structure that tilts inwardly and deeply relative to the fixing seat 3 .

[0019] The fixing base 3 , the recessed portion 31 , the connecting portion 21 and the earmuff 2 are an integral structure and are made of silicone material by injection molding.

[0020] The sound outlet hole 5 passes through the connecting portion 21 and the fixing base 3 from the bottom of the earmuff 2 , and the hole diameter of the sound outlet hole 5 in the connecting portion 21 is smaller than the hole diameter of the sound outlet hole 5 in the fixing base 3 .

[0021] A buckle portion 32 is provided in the fixing seat 3 , and a buckle groove 12 is provided on the fixing portion 11 . After the fixing portion 11 is inserted into the fixing seat 3 , the buckle portion 32 is buckled into the buckle groove 12 to fix the earmuff 2 to the earplug body 1 .

[0022] The height of the fixing base 3 is lower than that of the earmuff 2 , so that the fixing base 3 does not protrude from the rear end of the earmuff 2 .

[0023] The surface of the locking portion 32 has an inwardly inclined portion, and the end of the fixing portion 11 also has an inwardly inclined and contracted portion. This structure can make the assembly operation smoother.

[0024] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
