Description

Technical Field

[0001] This utility model relates to the field of audio, and in particular to an ear cap and an earplug including the ear cap. Background Technology

[0002] Earplugs are accessories for earbuds or headphones, and typically include a connector for connection and a soundproof cap that covers the connector.

[0003] Since the ear canal is in direct contact with the ear, it is made relatively soft to ensure comfort. This means that traditional ear canals can deform significantly when the ear is slightly compressed, such as when the user is lying on their side, which greatly reduces their sound insulation effect. Utility Model Content

[0004] Therefore, it is necessary to provide an ear cap that can solve the above problems.

[0005] In addition, it is necessary to provide an earplug that includes the aforementioned ear cap.

[0006] An ear cap includes a connecting post and a soundproof cap covering the connecting post;

[0007] The upper end of the connecting column is connected to the upper end of the soundproof cap. The lower end of the connecting column is provided with an installation hole. The lower end of the connecting column extends outward to form an annular support protrusion. The lower end of the soundproof cap is arranged around the periphery of the support protrusion. An annular soundproof cavity is formed between the soundproof cap and the connecting column.

[0008] In one embodiment, the outer side of the support protrusion extends downward and outward to form a sound-damping ring, and the sound-damping ring, the support protrusion, and the lower end of the connecting post together form a first groove.

[0009] In one embodiment, the sidewalls and / or bottom wall of the first groove are provided with a sound-absorbing structure.

[0010] In one embodiment, the thickness of the soundproof cap is 0.5mm to 0.8mm, the distance between the inner wall of the lower end of the soundproof cap and the support protrusion is 0.5mm to 1mm, the distance between the projection of the lower end of the soundproof cap onto the axial direction of the ear cap and the projection of the sound-blocking ring onto the axial direction of the ear cap is 0.9mm to 1.4mm, and the height of the sound-blocking ring is 0.8mm to 1.5mm.

[0011] In one embodiment, the soundproof cap includes, from top to bottom, an ear-insertion area, a fitting area, and a flat area connected in sequence;

[0012] The curvature of the sidewall of the ear-in area gradually decreases from top to bottom, the curvature of the sidewall of the fitting area gradually decreases from top to bottom, and the curvature of the sidewall of the flat area remains unchanged from top to bottom.

[0013] In one embodiment, the curvature of the sidewall at the connection between the ear-in area and the fitting area is R-angle 4° to R-angle 7°, and the curvature of the sidewall of the flat area is 1° to 4°.

[0014] In one embodiment, the height of the in-ear area is 2.6 mm, the height of the fitting area is 3 mm, and the height of the flat area is 4.6 mm to 5.5 mm.

[0015] In one embodiment, a second groove is provided at the top of the ear inlet area.

[0016] In one embodiment, the projection of the sidewall of the second groove onto the axial direction of the ear cap falls within the projection of the upper end of the connecting post onto the axial direction of the ear cap, and the depth of the second groove is 0.2 mm to 1.5 mm.

[0017] An earplug, including the aforementioned ear cap.

[0018] The lower end of the soundproof cap of this invention is arranged around the periphery of the supporting protrusion, and the lower end of the connecting post is provided with the annular supporting protrusion. This reduces the distance between the lower end of the soundproof cap and the supporting protrusion, so that when the ear cap is inserted into the ear, there is slight compression on the ear, such as when the user is lying on their side. This not only reduces the deformation space of the soundproof cap, but the supporting protrusion can also support the lower end of the soundproof cap, thereby reducing the degree of deformation of the soundproof cap, greatly reducing the risk of sound leakage, ensuring a sealed soundproof environment, and avoiding a significant reduction in the soundproofing effect caused by large deformation of the soundproof cap.

[0019] Compared with traditional ear caps, the ear cap of this utility model provides support to the lower end of the soundproof cap through the supporting protrusion, thereby reducing the deformation of the soundproof cap, reducing the risk of sound leakage, and improving the stability of the soundproofing effect.

[0020] In addition, the support protrusion can also block sound from entering the annular soundproof cavity.

[0021] Preferably, the outer side of the support protrusion extends downward and outward to form the sound-blocking ring, which can further block sound entering the annular sound insulation cavity.

[0022] Preferably, the sidewalls and / or bottom walls of the first groove are provided with the sound-absorbing structure. The sound-absorbing structure can effectively reduce the noise intensity of the sound entering the first groove, thereby achieving a better noise reduction effect.

[0023] Preferably, the soundproof cap includes, from top to bottom, the ear-insulating area, the fitting area, and the flat area connected in sequence; the curvature of the sidewall of the ear-insulating area gradually decreases from top to bottom, the curvature of the sidewall of the fitting area gradually decreases from top to bottom, and the curvature of the sidewall of the flat area remains unchanged from top to bottom.

[0024] The above design, by simulating the lever principle, allows the contact area that is in direct contact with the ear canal to exert optimal support, making the soundproof cap less prone to deformation and thus making it fit better for sealing and sound insulation.

[0025] Preferably, the height of the in-ear area is 2.6mm, the height of the fitting area is 3mm, and the height of the flat area is 4.6mm to 5.5mm, so that the overall height of the soundproof cap is about 10.5mm. This not only improves the fit for different ear canal sizes and shapes, but also greatly enhances the sound insulation effect and wearing stability. It ensures that users can maintain a stable and strong sound insulation effect even when using the cap in different environments or sleeping positions. It also enhances the sound insulation effect and wearing stability, ensuring that users can maintain a stable wearing effect even when lying on their side.

[0026] Preferably, the top of the ear-in-ear area is provided with the second groove, thereby reducing the thickness of the top of the ear-in-ear area, reducing the elasticity generated by the deformation of the top of the ear-in-ear area after the ear cap is inserted into the ear, and reducing the feeling of pressure when wearing the ear.

[0027] Preferably, the projection of the sidewall of the second groove in the axial direction of the ear cap falls within the projection of the upper end of the connecting post in the axial direction of the ear cap, thereby avoiding the impact on the overall mechanical strength of the ear cap after the thickness of the top of the ear inlet area is reduced.

[0034] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The ear cap of one embodiment shown includes a connecting post 10 and a soundproof cap 20 covering the connecting post 10.

[0036] The upper end of the connecting post 10 is connected to the upper end of the soundproof cap 20. The lower end of the connecting post 10 is provided with an installation hole 101. The lower end of the connecting post 10 extends outward to form an annular support protrusion 12. The lower end of the soundproof cap 20 is arranged around the support protrusion 12. An annular soundproof cavity 102 is formed between the soundproof cap 20 and the connecting post 10.

[0037] The lower end of the soundproof cap 20 of this invention is arranged around the periphery of the support protrusion 12. The lower end of the connecting post 10 is provided with an annular support protrusion 12, which reduces the distance between the lower end of the soundproof cap 20 and the support protrusion 12. This results in slight compression of the ear after the ear is inserted, such as when the user is lying on their side. This not only reduces the deformation space of the soundproof cap 20, but the support protrusion 12 can also provide support for the lower end of the soundproof cap 20, thereby reducing the degree of deformation of the soundproof cap 20, greatly reducing the risk of sound leakage, ensuring the sealing and soundproofing effect, and avoiding the significant reduction in soundproofing effect caused by large deformation of the soundproof cap 20.

[0038] Compared with traditional ear caps, the ear cap of this utility model provides support to the lower end of the soundproof cap 20 through the support protrusion 12, thereby reducing the deformation of the soundproof cap 20, reducing the risk of sound leakage, and improving the stability of the soundproofing effect.

[0039] In addition, the support protrusion 12 can also block sound entering the annular sound insulation cavity 102.

[0040] Referring to the accompanying drawings, in this embodiment, the upper end of the connecting post 10 is recessed, so that the upper space of the mounting hole 101 is smaller than the lower end of the mounting hole 101, thereby reducing the feeling of pressure when the ear cap is inserted into the ear.

[0041] Referring to the accompanying drawings, in this embodiment, the angle between the outer wall of the connecting post 10 and the inner wall of the soundproof cap 20 is 20°, which can reduce the feeling of pressure when the ear cap is inserted into the ear.

[0042] It should be noted that in this embodiment, both the connecting post 10 and the soundproof cap 20 are made of nanoporous liquid soft material (e.g., silicone), which can absorb and reduce most of the noise from the outside, thereby reducing the intensity of the noise.

[0043] Specifically, in this embodiment, the ear cap is manufactured as a single piece.

[0044] Preferably, in this embodiment, the hardness of the silicone is between 25 and 60 degrees. In other embodiments, materials with appropriate hardness can be selected according to actual needs.

[0045] Preferably, in conjunction with the accompanying drawings, in this embodiment, the outer side of the support protrusion 12 extends downward and outward to form a sound-blocking ring 14, and the sound-blocking ring 14, the support protrusion 12 and the lower end of the connecting post 10 together form a first groove 103.

[0046] The outer side of the support protrusion 12 extends downward and outward to form a sound-blocking ring 14, which can further block the sound entering the annular sound insulation cavity 102.

[0047] Preferably, in this embodiment, the sidewalls and / or bottom walls of the first groove 103 are provided with a sound-absorbing structure 104.

[0048] The noise reduction structure 104 can reduce the noise intensity of sounds entering the first groove 103, thereby achieving a better noise reduction effect.

[0049] More preferably, in this embodiment, the sound-absorbing structure 104 is a plurality of multifaceted convex rhombuses. It should be noted that in this invention, a prism is called a faceted prism if it has a certain number of sides.

[0050] Referring to the accompanying drawings, specifically in this embodiment, the noise-absorbing structure 104 is a five-sided convex rhombus.

[0051] Preferably, in this embodiment, the thickness of the soundproof cap 20 is 0.5mm to 0.8mm, the distance between the projection of the lower end of the soundproof cap 20 onto the axial direction of the ear cap and the projection of the sound-blocking ring 14 onto the axial direction of the ear cap is 0.9mm to 1.4mm, and the height of the sound-blocking ring 14 is 0.8mm to 1.5mm.

[0052] Preferably, in this embodiment, the distance between the inner wall of the lower end of the soundproof cap 20 and the support protrusion 12 is 0.5mm to 1mm, so that the support protrusion 12 can better support the soundproof cap 20, reduce the deformation of the soundproof cap 20, reduce the risk of sound leakage, and improve the stability of the soundproofing effect.

[0053] Preferably, in conjunction with the accompanying drawings, in this embodiment, the soundproof cap 20 includes, from top to bottom, an ear-insertion area 22, a fitting area 24, and a flat area 26 connected in sequence.

[0054] When the user wears the ear cap, the fitting area 24 provides the optimal area for a tight seal with the user's ear canal.

[0055] It should be noted that when the user wears the ear cap, part of the flat area 26 will also fit into the user's ear canal.

[0056] The curvature of the sidewall of the ear inlet area 22 gradually decreases from top to bottom, the curvature of the sidewall of the fitting area 24 gradually decreases from top to bottom, and the curvature of the sidewall of the flat area 26 remains unchanged from top to bottom.

[0057] The above design, by simulating the lever principle, allows the contact area 24, which is in direct contact with the ear canal, to exert the best support force, making the soundproof cap 20 less prone to deformation and making it fit better for sealing and sound insulation.

[0058] Preferably, in this embodiment, the curvature of the sidewall at the connection between the ear-in area 22 and the fitting area 24 is R angle 4° to R angle 7°, and the curvature of the sidewall of the flat area 26 is R angle 18° to R angle 23°.

[0059] It should be noted that, in order to achieve adaptability, by continuously summarizing the ear canal structure and size of Chinese people, and using the new ear cap, we have created exclusive golden specifications for men and women, which fit each user's ear canal better. Specifically, there are four inner diameter specifications, namely XS=10mm (child's ear canal), S=11mm (women's ear canal), M=11.6mm (men's ear cap), and L=12.5mm (large ear canal).

[0060] More preferably, in this embodiment, the height of the ear-in area 22 is 2.6 mm, the height of the fitting area 24 is 3 mm, and the height of the flat area 26 is 4.6 mm to 5.5 mm.

[0061] The aforementioned height design ensures that the overall height of the soundproof cap is approximately 10.5mm, which not only improves the fit of different ear canals but also enhances the sound insulation effect and wearing stability, ensuring that users can maintain a strong sound insulation effect even in different environments or sleeping positions.

[0062] Referring to the accompanying drawings, in this embodiment, a second groove 201 is provided at the top of the ear inlet area 22.

[0063] The top of the ear inlet area 22 is provided with a second groove 201, which reduces the thickness of the top of the ear inlet area 22, reduces the elasticity caused by the deformation of the top of the ear inlet area 22 after the ear cap is inserted into the ear, and reduces the feeling of pressure when wearing the ear.

[0064] More preferably, in this embodiment, the projection of the sidewall of the second groove 201 in the axial direction of the ear cap falls within the projection of the upper end of the connecting post 10 in the axial direction of the ear cap, and the depth of the second groove 201 is 0.2mm to 1.5mm.

[0065] The projection of the sidewall of the second groove 201 onto the axial direction of the ear cap falls within the projection of the upper end of the connecting post 10 onto the axial direction of the ear cap, thereby avoiding the impact on the overall mechanical strength of the ear cap after the top thickness of the ear inlet area 22 is reduced.

[0066] It should be noted that in this embodiment, the top of the ear inlet area 22 is closed, so that the ear cap can be used with the earplug.

[0067] In other embodiments, the top of the in-ear area 22 may be provided with a through hole, which forms a sound outlet channel after communicating with the mounting hole 101. In this case, the ear cap is suitable for earplugs or headphones.
