Description

Technical Field

[0001] The present application relates to the technical field of ear wearable devices, and in particular to an earplug, an earphone, and an accessory for ear wear. Background Art

[0002] The earplug can be inserted into the ear canal to isolate external noise or be used for fixing. The earplug can be combined with a sound-emitting element to form an earphone, and the earplug can also be combined with a decorative piece to play a decorative role.

[0003] A typical earplug consists of a plug and an operating element. The plug includes a connecting tube and a contact cap located at the inner end of the connecting tube. A deformation space is formed between the contact cap and the outer circumference of the connecting tube. The operating element engages the outer end of the connecting tube to connect with the plug. To install the earplug, grasp the exposed end of the operating element, move it, and then insert the plug into the ear canal. Ideally, the contact cap should deform evenly to ensure long-term wear comfort. However, in practice, it is difficult to control the spatial position of the plug in the ear canal.

[0004] To improve wearing comfort, the Chinese utility model patent, CN202873022U, titled "An In-Ear Headphone Earplug," proposes an earplug that replaces the contact cap with multiple circumferentially arranged elastic sheets. While this earplug reduces the difficulty of fitting into the ear canal and improves wearing comfort through the inward deformation of the multiple elastic sheets, this shape also makes it more susceptible to dirt and grime, making long-term use prone to ear canal diseases. Utility Model Content

[0005] The main purpose of this application is to propose an earplug, earphones and ear accessories, which aim to solve the technical problem that existing earplugs are difficult to evenly fill the ear canal to ensure wearing comfort and keep the ear canal clean.

[0006] To achieve the above-mentioned purpose, the earplug proposed in this application includes a terminal plug and an operating member, the outer end surface of the terminal plug is provided with a rotation groove, the inner wall surface of the rotation groove is a concave arc surface; the inner end of the operating member is formed with a rotating head, the rotating head is detachably embedded in the rotating groove, the outer surface of the rotating head has a convex arc surface adapted to the concave arc surface, the convex arc surface and the concave arc surface can be rotatably matched to enable the operating member to rotate non-directionally relative to the terminal plug.

[0007] Preferably, a position-avoiding inclined surface is provided at the connection between the inner wall surface of the rotating groove and the outer end surface of the terminal plug.

[0008] Preferably, the inner end surface of the terminal plug is provided with a through hole communicating with the rotation groove, and the inner diameter of the through hole is smaller than the minimum inner diameter of the avoidance inclined surface.

[0009] Preferably, the terminal plug is made of flexible material, and an avoidance groove is provided on the inner end surface of the terminal plug corresponding to the rotation groove, the inner diameter of the avoidance groove is smaller than the inner diameter of the rotation groove, and the through hole is provided on the bottom wall surface of the avoidance groove.

[0010] Preferably, the operating member is provided with a channel extending between an outer end surface and an inner end surface of the operating member, and the channel is communicated with the through hole.

[0011] Preferably, the inner diameter of the inner opening of the channel is smaller than the inner diameter of the through hole.

[0012] Preferably, the terminal plug includes a core and a contact portion connected to the core, the rotation groove is opened on the outer end surface of the core, the contact portion is arranged on the periphery of the core, and the outer end surface of the contact portion is higher than the outer end surface of the core.

[0013] Preferably, the core is cylindrical, the contact portion is connected to the inner end of the core, the contact portion is a thin-walled structure and a deformation cavity is formed between the contact portion and the core;

[0014] The operating member includes a gripping portion, a connecting shaft and the rotating head. The outer diameters of the gripping portion and the rotating head are both larger than the outer diameter of the connecting shaft. The gripping portion protrudes from the outer circumferential surface of the connecting shaft. When the central axis of the operating member is aligned parallel to the central axis of the terminal plug, the inner end surface of the gripping portion is higher than the outer end surface of the contact portion.

[0015] The present application also proposes an earphone, comprising an earplug and a sound-emitting element provided in the earplug, wherein the earplug is the earplug described above.

[0016] The present application also proposes an accessory for ear wear, comprising an earplug and a decorative piece, wherein the earplug is the earplug as described above, the decorative piece is connected to or integrally arranged with the operating piece, and the outer surface of the decorative piece has a clamping surface that clamps with the inner wall of the auricle.

[0017] The present invention utilizes a universally rotatable connection between the operating member and the terminal plug, thereby flexibly adjusting the spatial position of the terminal plug within the ear canal, thereby more conveniently and evenly filling the ear canal with the terminal plug. This eliminates the need for an elastic pleated structure on the outer circumference of the plug, thereby eliminating the need for a complex outer surface. This facilitates both manufacturing and maintaining a clean outer surface. Furthermore, because the terminal plug is detachably connected to the operating member, the terminal plug can be replaced if it becomes difficult to clean or becomes aged.

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] Reference Figures 1 to 6 In one embodiment, the earplug 100 proposed in the present application includes a terminal plug 10 and an operating member 20. The outer end surface of the terminal plug 10 is provided with a rotation groove 12, and the inner wall surface of the rotation groove 12 is a concave arc surface 13; the inner end of the operating member 20 is formed with a rotating head 21, which is detachably embedded in the rotation groove 12. The outer surface of the rotating head 21 has a convex arc surface 22 adapted to the concave arc surface 13. The convex arc surface 22 and the concave arc surface 13 can be rotatably matched to enable the operating member 20 to rotate non-directionally relative to the terminal plug 10.

[0029] In this embodiment, the terminal plug 10 is at the innermost side and is directly connected to the operating member 20, so the rotation radius of the terminal plug 10 is relatively small. The terminal plug 10 blocks the ear canal 201 by deforming its shape or outer surface. In order to improve wearing comfort, the terminal plug 10 is usually made of a flexible material, such as silicone or rubber. The operating member 20 is used for the user to apply force to the terminal plug 10 in an indirect manner, so the operating member 20 is usually made of a hard part, such as hard plastic. The outer end of the operating member 20 is preferably flat, so that it is convenient to grasp and rotate. The concave arc surface 13 can be a spherical arc surface or a plurality of connected spherical arc surfaces.

[0030] The present application utilizes a universally rotatable connection between the operating member 20 and the terminal plug 10, thereby flexibly adjusting the spatial position of the terminal plug 10 within the ear canal 201. This allows the terminal plug 10 to more easily and evenly fill the ear canal 201 without requiring an elastic pleated structure to be provided on the outer circumference of the plug 10. Consequently, the terminal plug 10 does not require a complex outer surface, thereby facilitating both manufacturing and maintaining a clean outer surface. Furthermore, since the terminal plug 10 is detachably connected to the operating member 20, the terminal plug 10 can be replaced if it becomes difficult to clean or becomes aged.

[0031] Furthermore, a position-avoiding inclined surface 14 is provided at the connection between the inner wall surface of the rotating groove 12 and the outer end surface of the terminal plug 10. In this way, the operating member 20 is not likely to interfere with the edge of the rotating groove 12 when rotating, thereby obtaining a larger adjustment operation space.

[0032] Furthermore, to facilitate the molding of the terminal plug 10, the inner end surface of the terminal plug 10 is provided with a through hole 15 connected to the rotating groove 12; in order to avoid improper assembly caused by the rotating head 21 passing through the through hole 15 during the assembly process, the inner diameter D1 of the through hole 15 is smaller than the minimum inner diameter D2 of the avoidance slope 14.

[0033] Furthermore, the terminal plug 10 is made of a flexible material, and a relief groove 16 is formed on the inner end surface of the terminal plug 10, corresponding to the rotation groove 12. This allows the inner end of the terminal plug 10 to better fit into or be inserted into the ear canal 201 by deforming toward the relief groove 16. The inner diameter D3 of the relief groove 16 is smaller than the inner diameter of the rotation groove 12. This reduces the structural strength of the relief groove 16 and weakens the inner end of the core 11. The via 15 is formed on the bottom wall of the relief groove 16. This allows the relief groove 16 with a larger inner diameter to be used to form the rotation groove 12, for example, to facilitate the clamping and removal of the mold.

[0034] Furthermore, the operating member 20 is provided with a channel 23 extending between the outer end surface and the inner end surface of the operating member 20 , and the channel 23 is communicated with the through hole 15 .

[0035] In this embodiment, the provision of the channel 23 can reduce the weight of the operating member 20. In the scenario of earphone application, the channel 23 can also be used to install a sound element or provide a path for sound propagation.

[0036] Furthermore, the inner diameter of the inner opening D4 of the channel 23 is smaller than the inner diameter D1 of the through hole 15. Thus, during the rotation of the operating member 20 relative to the terminal plug 10, the communicating area between the channel 23 and the through hole 15 is maximized.

[0037] Furthermore, the terminal plug 10 includes a core 11 and a contact portion 17 connected to the core 11, the rotation groove 12 is opened on the outer end surface of the core 11, the contact portion 17 is provided on the periphery of the core 11, and the outer end surface of the contact portion 17 is higher than the outer end surface of the core 11. Figure 5 As shown in H1 , by avoiding interference between the contact portion 17 and the operating member 20 in a larger range, a larger operating space can be provided for the operating member 20 .

[0038] Furthermore, the core 11 is cylindrical, and the contact portion 17 is connected to the inner end of the core 11. The contact portion 17 is a thin-walled structure and a deformation cavity 18 is formed between the contact portion 17 and the core 11, so that the contact portion 17 can use its own deformation to more evenly fill the ear canal 201. The operating member 20 includes a gripping portion 24, a connecting shaft 25, and a rotating head 21. The outer diameters of the gripping portion 24 and the rotating head 21 are both larger than the outer diameter D5 of the connecting shaft 25. The gripping portion 24 protrudes from the outer circumference of the connecting shaft 25. When the central axis of the operating member 20 is aligned parallel to the central axis of the terminal plug 10, the inner end surface of the gripping portion 24 is higher than the outer end surface of the contact portion 17. Figure 5 As shown in H2 , the compact structure formed at the connecting shaft 25 can also avoid interference between the connecting shaft 25 and the contact portion 17 within a larger operating space, so that the operating member 20 can rotate within a larger range.

[0039] This application also provides an earphone, comprising an earplug 100 and a sound-emitting element disposed on the earplug 100. The earplug 100 is the earplug 100 described above. The specific structure of the earplug 100 is referenced to the above embodiments. Since this earphone adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be detailed here.

[0040] This application also provides an earplug 200 accessory, comprising an earplug 100 and a decorative piece. The earplug 100 is as described above. The decorative piece is connected to or integrally formed with an operating member 20. The outer surface of the decorative piece has a retaining surface that engages with the inner wall of the auricle 202. The decorative piece can have various decorative shapes, such as geometric shapes or animal figures. The specific structure of the earplug 100 is similar to that of the above-described embodiments. Since this earplug 200 accessory utilizes all the technical solutions of all the above-described embodiments, it also possesses all the beneficial effects brought about by the technical solutions of the above-described embodiments, and will not be further elaborated here.
