Technical Field

[0001] The invention relates to the technical field of earmuff manufacturing, and in particular to an earmuff manufacturing process, an earmuff and an earphone. Background Art

[0002] One of the factors that affects the quality of headphones is the quality of the earmuffs.

[0003] In the related art, in order to make the earmuffs have better skin-friendly properties and sound-transmitting effects, the base material of the earmuffs is preferably a mesh cloth. However, due to the soft texture of the mesh cloth, after the mesh cloth is processed into a shape that fits the human ear, it is difficult for the mesh cloth itself to maintain a molded state for a long time. Therefore, in existing earmuffs, it is often necessary to use plastic parts such as ABS and PC to support the mesh cloth so that the mesh cloth can remain in a molded state.

[0004] However, plastic parts such as ABS and PC will increase the overall weight of the earmuffs. Summary of the invention

[0047] Reference below Figures 1 to 6 The earmuff manufacturing process according to the first aspect of the present invention is described in detail.

[0048] refer to Figure 1 The earmuff manufacturing process according to the embodiment of the present invention includes but is not limited to the following steps:

[0049] Step S100, hardening the mesh to obtain a mesh layer 100, wherein the mesh layer 100 has a composite area 110 located at the edge and a deformation area 120 located in the middle, wherein the hardened mesh layer 100 can remain in the deformed state after being deformed by an external force;

[0050] Step S200, compounding the PET layer 200 in the compounding area 110 of the mesh layer 100;

[0051] Step S300: stamping the deformation area 120 of the mesh layer 100 to form an earmuff.

[0052] It should be noted that the texture of the mesh cloth is relatively soft. If the deformation zone 120 of the mesh cloth layer 100 is directly stamped and formed, it is difficult for the mesh cloth layer 100 to maintain the formed state for a long time. Therefore, in the prior art, after the deformation zone 120 of the mesh cloth layer 100 is stamped and formed, it is necessary to use plastic parts such as ABS and PC to support the formed mesh cloth layer 100 so that the mesh cloth layer 100 can maintain the formed state for a long time. Correspondingly, the provision of plastic parts such as ABS and PC makes the overall weight of the earmuffs larger, and plastic parts such as ABS and PC will affect the overall appearance of the earmuffs.

[0053] In the earmuff manufacturing process of the present invention, the mesh cloth is first hardened to obtain the mesh cloth layer 100, wherein the mesh cloth layer 100 has a composite area 110 located at the edge and a deformation area 120 located in the middle, wherein the hardened mesh cloth layer 100 can remain in the deformed state after being deformed by an external force, and then, the composite area 110 of the mesh cloth layer 100 is composited with a PET layer 200, and then, the deformation area 120 of the mesh cloth layer 100 is stamped to form the earmuff. Because the deformation zone 120 of the mesh cloth layer 100 undergoes a hardening treatment before the stamping forming, the deformation zone 120 of the mesh cloth layer 100 can maintain the molded state for a long time after the stamping forming, and there is no need to use plastic parts such as ABS and PC to support the molded mesh cloth layer 100. Accordingly, the earmuffs made by the earmuff manufacturing process of the present invention do not need to be additionally provided with plastic parts such as ABS and PC, so that the earmuffs made by the earmuff manufacturing process of the present invention can be lighter, the wearing comfort of the user is improved, and the aesthetics can be better.

[0054] It can be understood that since the earmuffs manufactured using the earmuff manufacturing process of the present invention no longer need to use plastic parts such as ABS and PC to support the molded mesh layer 100, the influence of plastic parts such as ABS and PC on the sound insulation performance of the earmuffs can be reduced, so that the earmuffs have a better sound quality experience.

[0055] It is understandable that since the earmuffs manufactured using the earmuff manufacturing process of the present invention no longer need to use plastic parts such as ABS and PC to support the molded mesh layer 100, the use of plastic parts in the earmuff manufacturing process is reduced, which is conducive to environmental protection and sustainable development.

[0056] It should be noted that when the mesh cloth layer 100 is hardened, if the degree of hardening of the mesh cloth layer 100 is relatively small, in this case, after the deformation zone 120 of the mesh cloth layer 100 is stamped and formed, it is difficult for the mesh cloth layer 100 to maintain the formed state for a long time; if the degree of hardening of the mesh cloth layer 100 is relatively large, in this case, the brittleness of the mesh cloth layer 100 is relatively large, and after the deformation zone 120 of the mesh cloth layer 100 is stamped and formed, the mesh cloth layer 100 is prone to breakage under the action of external force, thereby affecting the normal use of the earmuffs produced subsequently.

[0057] Based on the above problems, in some embodiments of the present invention, reference Figure 2 In step S100, the following steps are included but not limited to:

[0058] Step S110, coating the mesh with slurry to increase a preset weight m per square meter of the mesh, wherein the preset weight m satisfies: 8.76 g ≤ m ≤ 11.26 g.

[0059] It is understandable that by coating the slurry on the mesh, the slurry can penetrate into the fiber structure of the mesh to enhance the overall plasticity of the mesh, so that the mesh layer 100 can maintain the deformed state for a long time after being deformed by an external force.

[0060] It should be noted that if more slurry penetrates into the fiber structure of the mesh, the overall plasticity of the mesh will be greater, and the overall brittleness of the mesh will be greater. In this case, when the mesh is deformed under the action of external force, the mesh is prone to breakage; therefore, the staff needs to control the amount of slurry coated on the mesh to achieve control of the hardening effect of the mesh.

[0061] In the earmuff manufacturing process of this embodiment, the slurry is coated on the mesh, and the weight of the slurry per square meter on the mesh is controlled to be within a preset weight m, wherein the preset weight m satisfies: 8.76 g ≤ m ≤

[0062] 11.26g, so that the hardened mesh cloth layer 100 has greater plasticity and lower brittleness, and further the hardened mesh cloth layer 100 can maintain the formed state for a long time after forming and is not easy to break.

[0063] In some embodiments of the present invention, the slurry is a water-based environmentally friendly adhesive of model ZS-9890B.

[0064] It should be noted that the material properties of meshes made of different materials are also different.

[0065] Based on the above problems, in some embodiments of the present invention, the material of the mesh is nylon, and the preset weight m satisfies: 10.01g≤m≤11.26g.

[0066] In other embodiments of the present invention, the mesh is made of polyester, and the preset weight m satisfies: 8.76g≤m≤10.76g.

[0067] In some embodiments of the present invention, reference Figure 3 In step S110, the following steps are also included but not limited to:

[0068] Step S111, rolling a layer of slurry on the front side of the mesh;

[0069] It should be noted that dust and other impurities may adhere to the surface of the mesh, and these impurities may affect the appearance of the earmuffs produced after subsequent processing.

[0070] It can be understood that coating a layer of slurry on the front of the mesh by rolling brushing can not only complete the coating of the slurry on the front of the mesh, but also remove dust and other impurities adhering to the front of the mesh in the process of rolling brushing the slurry, so that the subsequently manufactured earmuffs have clearer hearing and better comfort.

[0071] Step S112, scraping the slurry on the front side of the mesh to remove excess slurry on the front side of the mesh;

[0072] It should be noted that if the slurry distribution uniformity on the front side of the mesh is poor, it will affect the subsequent forming effect of the mesh layer 100, resulting in the forming shape of some areas of the mesh layer 100 being able to be maintained for a long time, while the forming shape of other areas is difficult to maintain for a long time.

[0073] It can be understood that after rolling a layer of slurry on the front side of the mesh, by scraping the slurry on the front side of the mesh, not only the excess slurry on the front side of the mesh can be removed, but also the distribution of the slurry on the front side of the mesh can be made more uniform, so as to improve the forming effect of the deformation zone 120 of the subsequent mesh layer 100.

[0074] Step S113, baking the mesh to solidify the slurry on the front side of the mesh;

[0075] It is understandable that by baking the mesh to solidify the slurry on the front side of the mesh, it is possible to increase the difficulty of the slurry on the front side of the mesh to fall off.

[0076] Step S114, rolling a layer of slurry on the reverse side of the mesh;

[0077] It can be understood that coating a layer of slurry on the back of the mesh by rolling brushing can not only complete the coating of the slurry on the back of the mesh, but also remove dust and other impurities adhering to the back of the mesh in the process of rolling brushing the slurry, so that the subsequently manufactured earmuffs have clearer hearing and better comfort.

[0078] Step S115, scraping the slurry on the back side of the mesh to remove excess slurry on the back side of the mesh;

[0079] It should be noted that if the slurry distribution uniformity on the back of the mesh is poor, it will affect the subsequent forming effect of the mesh layer 100, resulting in the forming shape of some areas of the mesh layer 100 being able to be maintained for a long time, while the forming shape of other areas is difficult to maintain for a long time.

[0080] It can be understood that after a layer of slurry is rolled on the back of the mesh, by scraping the slurry on the back of the mesh, not only can the excess slurry on the back of the mesh be removed, but the distribution of the slurry on the back of the mesh can also be made more uniform, so as to improve the forming effect of the deformation zone 120 of the subsequent mesh layer 100.

[0081] Step S116: baking the mesh to solidify the slurry on the back side of the mesh.

[0082] It is understandable that by baking the mesh to solidify the slurry on the front side of the mesh, it is possible to increase the difficulty of the slurry on the front side of the mesh to fall off.

[0083] In some embodiments of the present invention, the aperture size of the mesh cloth is 0.3 mm to 2 mm. For example, the aperture size of the mesh cloth can be selected to be 0.3 mm, 1 mm, 1.5 mm or 2 mm.

[0084] It should be noted that if the aperture of the mesh is too large, the slurry will not easily adhere to the surface of the mesh; if the aperture of the mesh is too small, when too much slurry is coated on the mesh, the slurry adhering to the surface of the mesh will not be easy to scrape off, so that too much slurry will easily remain on the surface of the mesh.

[0085] In the earmuff manufacturing process of the present invention, by setting the aperture size of the mesh cloth to 0.3 mm to 2 mm, the slurry can be easily adhered to the surface of the mesh cloth while the slurry adhered to the surface of the mesh cloth can be easily scraped off.

[0086] In some embodiments of the present invention, reference Figure 2 In step S100, the following steps are also included but not limited to:

[0087] Step S120 , cutting the hardened mesh cloth to form a plurality of mesh cloth layers 100 .

[0088] It is understandable that the overall volume of the mesh layer 100 is relatively small, and its size is 40mm×13mm, and it is difficult to apply slurry on the mesh layer 100; in the earmuff manufacturing process of the present embodiment, applying slurry on the mesh before cutting the mesh can make the application of slurry on the mesh more convenient.

[0089] Specifically, the hardened mesh is laser cut using a laser machine.

[0090] In some embodiments of the present invention, reference Figure 4 In step S200, the following steps are included but are not limited to:

[0091] Step S210, placing the protective layer and the mesh layer 100 in a hot pressing lower mold, and making the protective layer separate the hot pressing lower mold and the mesh layer 100;

[0092] Step S220, placing the PET layer 200 on the composite area 110 of the mesh layer 100, with the side of the PET layer 200 having the hot melt adhesive facing the mesh layer 100;

[0093] Step S230 , driving the hot pressing upper mold and the hot pressing lower mold to approach each other, so that the PET layer 200 is thermally laminated to the laminating area 110 of the mesh layer 100 .

[0094] It should be noted that if the mesh layer 100 directly contacts the hot press lower mold, in this case, after the hot press upper mold and the hot press lower mold cooperate to composite the PET layer 200 to the composite area 110 of the mesh layer 100, since the mesh layer 100 directly contacts the hot press lower mold, the texture on the surface of the hot press lower mold will be printed on the mesh layer 100, thereby affecting the appearance of the earmuffs processed subsequently.

[0095] In the earmuff manufacturing process of the present invention, a protective layer is provided, and the protective layer separates the hot pressing lower mold and the mesh layer 100. Thus, in the process of the hot pressing upper mold and the hot pressing lower mold cooperating to compound the PET layer 200 to the compounding area 110 of the mesh layer 100, the protective layer can protect the mesh layer 100, so as to reduce the generation of surface textures of the mesh layer 100, thereby improving the appearance of the earmuffs processed subsequently.

[0096] In a specific embodiment of the present invention, the protective layer is a silicone layer.

[0097] In some embodiments of the present invention, reference Figure 5 The manufacturing process of the PET layer 200 includes but is not limited to the following steps:

[0098] Step S410, cutting the PET blank to form a plurality of PET sheets 210, wherein the area of ​​the PET sheet 210 is larger than the area of ​​the PET layer 200;

[0099] Step S420, cutting the hot melt adhesive blank to form a plurality of hot melt adhesive sheets 220;

[0100] Step S430, attaching the hot melt adhesive sheet 220 to one side of the PET sheet 210 to form a PET layer semi-finished product;

[0101] Step S440 , fine-cutting the semi-finished PET layer product to remove the excess of the semi-finished PET layer product and form a finished PET layer 200 .

[0102] It is understandable that due to the influence of errors, after the PET sheet 210 and the hot-melt adhesive sheet 220 are compounded, it is difficult for the two to overlap exactly. If the area of ​​the PET sheet 210 is exactly equal to the area of ​​the PET layer 200, and the area of ​​the hot-melt adhesive sheet 220 is exactly equal to the area of ​​the PET layer 200, there will be a certain misalignment between the PET sheet 210 and the hot-melt adhesive sheet 220 in the PET layer 200 formed by the subsequent compounding, thereby affecting the quality of the earmuffs manufactured subsequently.

[0103] In the earmuff manufacturing process of the present invention, since the area of ​​the PET sheet 210 is larger than the area of ​​the PET layer 200, and the area of ​​the hot melt adhesive is larger than the area of ​​the PET layer 200, after the PET sheet 210 and the hot melt adhesive sheet 220 are compounded to form the PET layer semi-finished product, although there is still a certain misalignment between the PET sheet 210 and the hot melt adhesive sheet 220, the misalignment between the PET sheet 210 and the hot melt adhesive sheet 220 can be eliminated by subsequent precision cutting of the PET layer semi-finished product, so that in the PET layer 200 of the finished product, the PET sheet 210 and the hot melt adhesive sheet 220 can just overlap.

[0104] In some embodiments of the present invention, reference Figure 6 In step S300, the following steps are included but are not limited to:

[0105] Step S310: Punch the deformation area 120 toward the side where the PET layer 200 is attached to form a groove, thereby forming an earmuff.

[0106] In a further embodiment of the present invention, reference Figure 6 In step S300, the following steps are also included but not limited to:

[0107] Step S320: trimming the edge of the earmuff to remove burrs on the edge of the earmuff.

[0108] It can be understood that by trimming the edge of the earmuff, the burrs on the edge of the earmuff can be removed, thereby making the earmuff have a better sense of layering.

[0109] Reference below Figure 7 The earmuff according to the second aspect of the present invention will be described in detail.

[0110] According to a second aspect of the present invention, an earmuff is provided, which is manufactured using the earmuff manufacturing process provided in the first aspect of the present invention.

[0111] refer to Figure 7The earmuff includes a mesh layer 100 and a PET layer 200. The mesh layer 100 includes a composite area 110 located at the edge and a deformation area 120 located in the middle. The PET layer 200 includes a hot-melt adhesive sheet 220 and a PET sheet 210. The PET sheet 210 is composited on the composite area 110 through the hot-melt adhesive sheet 220. The deformation area 120 is recessed toward the side of the mesh layer 100 where the PET layer 200 is composited to form a groove.

[0112] The headset provided according to the embodiment of the third aspect of the present invention includes the earmuff provided by the embodiment of the second aspect of the present invention.
