[0002] Traditionally, the shells of speaker equipment are mostly made of plastic, carbon fiber, metal or woven fabric as the base materials, and are given unique colors and effects through post-processing processes such as spraying, printing, and coating. Transparent materials can give speaker equipment a sense of modernity and technology, but the simple use of transparent materials, based on the light transmittance of transparent materials, often exposes the internal structural parts of the speaker equipment, as well as appearance defects such as gates, stress marks, and BOSS columns generated during the injection molding process, which seriously affects the appearance of the speaker equipment. In addition, the application of transparent materials is also limited by their own injection molding and molding characteristics, making it difficult to achieve complex and varied appearance designs.

[0048] Various exemplary embodiments of the present application are now described in detail. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application unless otherwise specifically stated.

[0049] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0050] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0051] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0052] The following describes in detail the housing of the speaker device and its preparation method and the speaker device provided in the embodiments of the present application in combination with specific embodiments.

[0053] According to an embodiment of the present application, a housing of a speaker device is provided. Figures 1 to 4The shell of the speaker device includes a shell body 1 and a grating layer 2; the shell body 1 is mainly composed of a plurality of cover plates, wherein each of the cover plates is formed into a specific shape by processing a transparent substrate 101; the grating layer 2 is arranged on the surface of the shell body, and the grating layer 2 is a line pattern composed of at least one element of a straight line, a curve and a broken line in a densely arranged manner, see Figure 5 and Figure 6 .

[0054] Specifically, see Figures 1 to 4 The housing of the speaker device of the embodiment of the present application includes a housing body 1 and at least one grating layer 2 formed on the surface of the housing body 1. The housing body 1 is designed to be mainly assembled by splicing a plurality of cover plates, and each cover plate is formed by processing a transparent substrate 101 with a certain thickness. The material of the transparent substrate 101 may include at least one of glass, plastic and carbon fiber composite material.

[0055] In the embodiment of the present application, the grating layer 2 is disposed on the surface of the housing body 1. The grating layer 2 is a line pattern composed of at least one element of straight lines, curves and broken lines in a densely arranged manner, see Figure 5 and Figure 6 The introduction of the grating layer 2 can produce a unique visual effect, which is described in detail below.

[0056] For the shell of the speaker of the present application, its main material is a transparent material, and the introduction of the grating layer 2 can produce a unique light reflection and refraction effect, so that the shell of the speaker device can present different images or visual effects at different angles, thereby enhancing the aesthetics and attractiveness of the product.

[0057] The dense lines of the grating layer 2 can effectively hide the appearance defects such as gates, stress marks, BOSS columns, etc. produced by the transparent substrate 101 (which will be processed into a cover plate of a specific shape later) or the cover plate (also transparent) during the injection molding process, as well as the disorderly internal structure of the speaker device, making the appearance of the speaker device look more neat and beautiful.

[0058] The housing of the speaker device provided in the embodiment of the present application has a wide range of application fields. The housing of the speaker device can also be applied to many electronic products such as headphones and smart wearable devices, and has a wide range of application prospects.

[0059] The shell of the speaker device provided in the embodiment of the present application has a shell body designed with a splicing structure (such as a push-pull and locking structure), which makes the shell of the speaker device easier to disassemble and assemble, so that the internal components of the speaker device can be easily installed and disassembled, thereby facilitating the repair and replacement of the internal components.

[0060] To sum up, the shell of the speaker device provided in this application has a unique and beautiful visual effect, can hide appearance defects and the messy structure inside the speaker device, has a wide range of applications, and is easy to disassemble and repair, providing new ideas and methods for the appearance design of the speaker device.

[0061] In the present application, the cover plate and the transparent substrate 101 are involved. It should be noted that the transparent substrate 101 is the basic material for making the cover plate, which is transparent and allows light to penetrate. During the processing, the transparent substrate 101 may need to go through processes such as cutting, grinding, and hot bending to form the required shape and size, that is, to form the cover plate.

[0062] That is to say, the cover plate in the present application is formed by processing the transparent substrate 101, and is a shell component with a specific shape and size. Multiple cover plates are spliced ​​to form a shell body, which can protect the internal structure of the speaker device and present a unique visual effect through the grating layer thereon.

[0063] In some examples of the present application, the grating layer 2 is formed by any of the following methods:

[0064] Forming the line pattern on the transparent substrate 101 by printing;

[0065] Forming the line pattern on the transparent substrate 101 by laser engraving; and

[0066] The line pattern is formed on the film 21 by printing or laser engraving, and then the film 21 is attached or injection-molded on the cover plate.

[0067] In this example of the present application, there are multiple options for forming the grating layer 2, which provide different technical paths to achieve the grating effect, and each has a specific technical effect.

[0068] The first forming method of the grating layer 2 is as follows:

[0069] The line pattern is formed on the transparent substrate 101 by printing. This method involves printing on the transparent substrate 101 using high-precision transparent UV ink.

[0070] Specifically, the ink is precisely attached to the transparent substrate 101 by screen printing or roller printing technology to form a densely arranged line pattern. The printing method can achieve a very fine line pattern, and the line density can reach a very high level (such as ≥600 lines / mm), thereby providing an excellent grating effect. The shape of the line (straight line, curve, broken line, etc.) and the arrangement method can be adjusted according to the design requirements, increasing the design flexibility of the product.

[0071] For mass production, printing is a cost-effective method.

[0072] The second method for forming the grating layer 2 is as follows:

[0073] A line pattern is formed on the transparent substrate 101 by laser engraving. This method involves using a laser engraving machine to form grooves on a pre-set transparent substrate 101 by light beam burning, thereby forming a line pattern.

[0074] Laser engraving can form grooves on the transparent substrate 101. Since the grating lines are physically engraved on the transparent substrate 101, this method has high durability and is not easy to wear.

[0075] The third method for forming the grating layer 2 is as follows:

[0076] A line pattern is formed on the film 21 by printing or laser engraving, and then the film is attached or injection molded on the cover. The film 21 is, for example, a PET film.

[0077] The third method is as follows: firstly, a line pattern is printed or laser engraved on a film, and then the film with the line pattern is attached or injection molded on the cover plate by intra-film injection or intra-film transfer.

[0078] This method allows the grating pattern to be first made on the diaphragm and then applied to the cover plate or the housing body 1 (the housing body 1 is mainly composed of multiple cover plates spliced ​​together) of different shapes and curves, thereby increasing the freedom of design.

[0079] For product surfaces with large curvature, using a film may be easier than directly printing or laser engraving on the transparent substrate 101 or cover. The film can fit tightly to various complex shapes of cover or housing body, including curved, concave or irregular surfaces, without sacrificing the presentation of the grating effect.

[0080] For the shell body that has been manufactured (mainly composed of multiple cover plates), direct film lamination is a fast and convenient post-processing method without the need for additional processing or modification of the shell body itself.

[0081] In addition, if the grating layer 2 is damaged or aged, only the diaphragm needs to be replaced without replacing the entire housing body.

[0082] The following describes in detail the method for realizing the grating layer 2 on the transparent substrate 101 (such as a glass substrate or a plastic substrate) and the film 21 (such as a PET film), including three main processes: printing, laser engraving and film printing.

[0083] Directly manufacturing the grating layer 2 on the transparent substrate 101 of the present application includes two processes.

[0084] (1) Printing process (i.e., embossing method), as follows:

[0085] A glass plate (suitable for a flat structure and cannot be bent) or a transparent plastic material is selected as the material of the transparent substrate 101 , and there is no specific requirement for the thickness.

[0086] Use ultra-fine steel screen, nylon screen printing or high-precision roller printing plate, and ensure that the screen mesh is not less than 400 mesh to ensure printing accuracy. When roller printing, the roller accuracy needs to be adjusted according to the line requirements.

[0087] The specific process of printing is as follows:

[0088] Lay the transparent substrate 101 flat and fix it under the screen (steel mesh or nylon mesh);

[0089] Fix the screen on the transparent substrate 101 and apply transparent UV ink;

[0090] The ink is evenly scraped with a scraper, and the ink leaks onto the transparent substrate 101 through the pattern on the screen to form the desired lines. The thickness of the line ink is controlled to be 1-20 μm. Of course, if roller printing is used, the screen is replaced with a roller engraved with lines, and rolling printing is performed on the transparent substrate 101;

[0091] Place the printed transparent substrate 101 in a UV irradiator at 600-1000 MJ / cm 2 In this way, the grating layer 2 is formed on the transparent substrate 101.

[0092] (2) Laser engraving process (i.e. recessed method), as follows:

[0093] Using a laser engraving machine, fine lines are engraved on the surface of the transparent substrate 101 by burning, and the lines are in various forms, including straight lines, curves, broken lines, etc. The depth of the groove formed by laser engraving is adjusted according to the effect requirements, ranging from 0.01mm to 0.1mm.

[0094] (3) When the curvature of the outer shell of the speaker device is large, a line pattern can be formed on a membrane 21 first. Specifically, a PET membrane with a thickness between 0.01 mm and 0.3 mm is selected, and a transparent UV grating strip is printed on the front of the PET membrane using screen printing or roller printing technology. The printed membrane is then attached or injection molded to the surface of the cover plate or the outer shell body by in-film injection molding or in-film transfer technology, see Figure 7 .

[0095] The above three processes are suitable for the production of grating structures in different scenarios. Raised printing is suitable for flat or slightly curved surfaces; recessed engraving provides another visual effect, especially suitable for occasions pursuing unique textures; and film printing is flexible and applicable to various complex curved surfaces, especially when traditional plate processing is limited. Each process requires strict control of the accuracy and depth of printing or engraving to ensure the quality and aesthetics of the final grating effect.

[0096] In some examples of the present application, the material of the transparent substrate 101 includes at least one of glass, plastic and carbon fiber composite material.

[0097] In this example of the present application, the material of the transparent substrate 101 is described, which includes at least one of glass, plastic and carbon fiber composite material. This provides a diversified solution for realizing the application of the grating structure on the housing of electronic products such as speaker equipment.

[0098] Glass material has excellent transparency and a certain hardness, can provide good optical properties and scratch resistance. It can also withstand higher temperatures and is suitable for use in high temperature processing environments.

[0099] Plastic materials are lightweight, low cost, easy to process and shape, and can meet the structural design requirements of complex shell bodies.

[0100] Carbon fiber composites have extremely high strength and stiffness while maintaining low weight, making them ideal for lightweight design. They also have good corrosion resistance and thermal stability.

[0101] By selecting transparent substrates 101 of different materials, the housing design requirements of different products can be met. For example, for a speaker device that requires high transparency and scratch resistance, a transparent substrate 101 made of glass can be selected as the material for making the housing body. For a speaker device that pursues lightweight and cost control, a transparent substrate 101 made of plastic or carbon fiber composite material can be selected as the material for making the housing body.

[0102] Different materials have different physical and chemical properties, and the appropriate transparent substrate 101 material can also be selected according to the use environment or working conditions of the speaker device. For example, for a speaker device working in a high temperature environment, a high temperature resistant glass material or a carbon fiber composite material can be selected as the material for making the transparent substrate 101. That is, a transparent substrate made of glass or a transparent substrate made of carbon fiber composite material is used to make the shell body.

[0103] Plastic materials and carbon fiber composite materials are easier to process and shape than glass materials, which can reduce production costs and cycles. In particular, plastic materials and carbon fiber composite materials have stronger plasticity in the design of complex shell bodies.

[0104] By properly selecting the material for the transparent substrate, the cost can be reduced while ensuring the performance of the speaker equipment. For example, for mass-produced products, choosing a transparent substrate made of a relatively low-cost plastic material can significantly improve economic benefits.

[0105] Different transparent substrate 101 materials have different adaptability to environmental factors. For example, a speaker device that works in a humid or corrosive environment can choose a corrosion-resistant carbon fiber composite material transparent substrate.

[0106] In the present application, the selection of the material of the transparent substrate 101 fully considers multiple factors such as the design requirements, performance requirements, processing convenience, cost-effectiveness and environmental adaptability of the speaker equipment, providing a basis for the application of the grating structure on the outer shell of the speaker equipment such as the speaker equipment.

[0107] In some examples of this application, see Figure 5 and Figure 6 , the line density of the line pattern is: ≥600 lines / mm.

[0108] Line density refers to the number of lines per unit length. In this example of the present application, the line density is ≥600 lines / mm, which means that there are at least 600 lines per millimeter of length.

[0109] See also Figure 5 and Figure 6 The lines in the line pattern may be straight lines, and the straight lines may be oblique lines, and the lines in the line pattern are densely arranged.

[0110] To achieve such a high line density, high-precision printing or engraving technology is required. For example, ultra-fine steel mesh or nylon screen printing, as well as high-precision roller printing or laser engraving technology are used. During the printing process, it is necessary to ensure uniform distribution and precise curing of the ink to achieve the desired grating effect.

[0111] The description of the line density of the line pattern in this example of the present application can bring at least the following technical effects:

[0112] (1) Enhanced grating effect: High-density lines can produce a more delicate and complex grating effect. When viewed from a certain angle, you can see richer light refraction and image changes. This effect is particularly significant on transparent shells, giving the speaker equipment a unique visual aesthetic.

[0113] (2) Improve shielding: When the line density is high enough, they can effectively conceal the messy internal structure of the speaker device, making it difficult to easily see the internal components of the speaker device from the outside. This is especially important for electronic products that use transparent materials as the casing, as it can maintain the aesthetics of the product while hiding unnecessary internal details.

[0114] The unique grating effect and high-quality appearance can significantly enhance the market competitiveness of products. Consumers are more inclined to choose products with unique designs and high-quality appearance, so this high-density line design helps to attract more consumers.

[0115] In some examples of this application, see Figure 7 The thickness of the diaphragm 21 is T, 0.01mm≤T≤0.3mm.

[0116] Among the methods for forming the grating layer 2 provided in the present application, a third method involves first forming a line pattern on the diaphragm 21 .

[0117] The thickness of the diaphragm 21 directly affects the difficulty of processing and the quality of the finished product. Within this thickness range, the diaphragm 21 printed with dense line patterns (i.e., grating structures) can be arranged on the surface of the housing body of the sound box device by using precise in-film injection molding or in-film transfer technology.

[0118] Although a thinner diaphragm can be bent and fit the surface of a complex shell body more easily, it also requires higher processing accuracy and more detailed printing process to ensure the clarity and uniformity of the grating effect. The thickness range of the diaphragm 21 provided in this example of the present application takes into account both the process difficulty and the fit with the shell body.

[0119] The diaphragm 21 within the thickness range of this example of the present application can be closely attached to the surface of the housing body of the speaker device, and is not prone to problems such as bubbles or warping. This allows the grating layer 2 to be evenly distributed on the surface of the housing body, presenting a clear and delicate visual effect.

[0120] While ensuring the transparent appearance of the speaker device, the grating structure on the diaphragm 21 can effectively cover the disordered internal structure of the speaker device. Even if the internal components of the speaker device are relatively complex, the refraction effect of the grating structure can be used to see a neat and beautiful appearance from the outside.

[0121] In some examples of this application, see Figures 1 to 4The shell body 1 is mainly composed of an upper cover plate 11, a lower cover plate 12, a left cover plate 13, a right cover plate 14, a front cover plate 15 and a rear cover plate 16; the upper and lower sides of the left cover plate 13 and the right cover plate 14 are respectively connected to the upper cover plate 11 and the lower cover plate 12 in a push-pull manner through a concave-convex structure to form a locking structure, and the upper cover plate 11, the lower cover plate 12, the left cover plate 13 and the right cover plate 14 are enclosed to form a shell frame with front and rear openings; the front cover plate 15 and the rear cover plate 16 are respectively detachably connected to the front and rear openings of the shell frame.

[0122] The embodiment of the present application provides a shell of a speaker device, wherein the shell body 1 can be decomposed into six independent cover plates, and each cover plate has its own specific shape and installation position.

[0123] The six cover plates in the present application are connected in a push-pull manner: the upper and lower sides of the left cover plate 13 and the right cover plate 14 are respectively connected to the upper cover plate 11 and the lower cover plate 12 in a push-pull manner through a concave-convex structure. This connection method not only simplifies the assembly process, but also makes the shell body more stable after closing and not easy to loosen.

[0124] See also Figures 1 to 4 In the present application, the cover plates connected by push-pull mode form a locking structure, which further enhances the stability and durability of the housing body. This locking mechanism ensures that the housing of the speaker device is not easily deformed or damaged when subjected to external forces.

[0125] In the present application, the front cover plate 15 and the rear cover plate 16 are detachably connected to the front and rear openings of the housing frame, respectively. This design makes it more convenient to repair and replace the internal components of the speaker device without disassembling the entire housing.

[0126] It can be seen that the solution provided in this example of the present application can simplify the assembly process, and at the same time, this design also reduces the difficulty of assembly. The design of the concave-convex structure locking makes the shell body more stable when closed and not easily deformed or damaged by external forces. This improves the overall quality and service life of the speaker equipment. The detachable front cover 15 and rear cover 16 design makes it easier and quicker to repair and replace internal components. Users do not need to disassemble the entire speaker equipment, but simply remove the front cover 15 and the rear cover 16 to perform internal repairs or upgrades.

[0127] This unique shell structure design not only improves the aesthetics of the product, but also enhances the user experience. During use, you can feel the stability and durability of the shell of the speaker equipment.

[0128] In addition, the spliced ​​shell structure design in the present application provides more possibilities for innovation of, for example, speaker equipment. Shell bodies of different shapes and styles can be designed according to different user needs and preferences, thereby meeting the diverse needs of the market.

[0129] In some examples of this application, see Figures 1 to 4 The front cover plate 15 and the rear cover plate 16 are respectively bonded and fixed to the front and rear openings of the outer shell frame.

[0130] In this embodiment of the present application, the front cover plate 15 and the rear cover plate 16 are respectively fixed to the front and rear openings of the housing frame by bonding. The bonding method has high strength, durability and good sealing performance, and is also convenient for disassembly.

[0131] The front cover plate 15 and the rear cover plate 16 fixed by bonding form a tight connection with the housing frame, thereby improving the structural strength of the entire housing body. This structure can better maintain stability when subjected to external impact or vibration, thereby extending the service life of the speaker device.

[0132] The bonding method can ensure a seamless connection between the front cover plate 15 and the rear cover plate 16 and the housing frame, thereby enhancing the sealing performance of the speaker device such as the speaker device. This helps prevent external substances such as dust and moisture from entering the interior of the device and protect the internal components of the device from damage.

[0133] The bonding method is simpler and faster than other connection methods such as screw fixing and snap connection. It does not require additional tools or equipment, nor does it require complicated assembly steps, thus reducing production costs and assembly difficulty.

[0134] In some examples of the present application, one of the upper cover plate 11, the lower cover plate 12, the left cover plate 13 and the right cover plate 14 is used to support internal components of the speaker device.

[0135] In the housing body of the present application, the internal components of the speaker device can be centrally arranged on one of the four push-pull cover plates, such as the upper cover plate 11, the lower cover plate 12, the left cover plate 13 and the right cover plate 14. In this way, when the speaker device needs to be repaired, the front cover plate 15 and the rear cover plate 16 can be opened first, and then the cover plate with the internal components of the speaker device can be pushed and pulled out for repair, which is very convenient.

[0136] In one example, according to the structure of the speaker device, the lower cover plate 12 can be used as a bearing plate to bear its internal components, because it is located at the bottom of the speaker device, which is convenient for supporting and fixing the internal components. The internal components of the speaker device include, for example, speaker units, circuit boards, batteries and other key components, which need to be reasonably arranged on the bearing plate to ensure the performance and stability of the speaker device.

[0137] The lower cover plate 12 (as a bearing plate) is combined with other cover plates such as the upper cover plate 11, the left cover plate 13, and the right cover plate 14 through a splicing structure to form a complete housing frame. This splicing structure is not only convenient for assembly and disassembly, but also helps to maintain the integrity and stability of the housing of the speaker device.

[0138] In addition, arranging the internal components on a cover plate can greatly simplify the assembly process. You only need to install all the internal components on the cover plate, and then splice the cover plate with other cover plates. The centralized layout of internal components can shorten the assembly time and improve the assembly efficiency, which is especially important for large-scale production and can significantly reduce production costs.

[0139] In the shell design of the speaker device provided in the embodiment of the present application, the use of transparent materials combined with the grating layer 2 can present unique visual effects at different angles, increasing the aesthetics and attractiveness of the shell of the speaker device. The grating structure in the grating layer 2 can hide the appearance defects generated during the injection molding process, such as gates, stress marks, etc., while covering the complex internal structural parts, making the overall appearance of the speaker device neater.

[0140] See also Figures 1 to 4 The outer shell of the speaker device may adopt a spliced ​​push-pull structure, such as an upper cover plate 11, a lower cover plate 12, a left cover plate 13, a right cover plate 14, a front cover plate 15 and a rear cover plate 16, which are easy to assemble and disassemble. The internal components may be centrally installed on a cover plate such as the lower cover plate 12, and combined with other cover plates by a convex-concave structure push-pull method to form a complete outer shell of the speaker device.

[0141] The shell design of the speaker device provided in the embodiment of the present application can also be applied to the shell of smart wearable devices. For example, it can be applied to the temples of AR glasses, the front panel of VR glasses, the strap of smart watches, etc., and its shell design needs to take into account both aesthetics and functionality. The grating structure of the grating layer 2 can increase the visual layering and technological sense of these devices, and enhance the user's wearing experience.

[0142] The shell design of the speaker device provided in the embodiment of the present application can be applied to the shell of the earphone. Specifically: the design of the earphone shell needs to focus on personalization and comfort. The grating layer 2 can provide a unique visual effect for the earphone shell, while meeting the user's demand for personalized appearance. The earphone shell may be manufactured using technologies such as injection molding or 3D printing, and the grating layer 2 can be implemented by means of diaphragm pasting. The application of the grating structure can make the earphone shell more unique in appearance and improve the recognition of the product. The personalized appearance design can meet the aesthetic needs of different users and increase the market appeal of the product.

[0143] According to an embodiment of the present application, a speaker device is provided, wherein the speaker device includes the housing of the speaker device as described above.

[0144] The speaker device provided in the embodiment of the present application has a shell made of transparent material, and a grating layer 2 is designed on the surface of the shell body 1. The grating lines in the grating layer 2 are arranged with equal width and equal spacing, forming a unique visual effect. When the user observes the speaker device from different angles, different light refraction effects can be seen, thereby increasing the stereoscopic sense and dynamic beauty of the speaker device.

[0145] In addition, the splicing structure of the housing body 1 makes assembly and disassembly easier and more convenient. At the same time, this design also helps to improve the maintainability and upgradeability of the speaker device.

[0146] According to an embodiment of the present application, a method for preparing a housing of a speaker device is provided, the method comprising the following steps S100 to S400:

[0147] Step S100, providing a transparent substrate 101;

[0148] Step S200, forming a grating layer 2 on the transparent substrate 101 by printing or laser engraving; wherein the grating layer 2 is a line pattern composed of at least one element of straight lines, curves and broken lines in a densely arranged manner;

[0149] Step S300, processing the transparent substrate 101 with the grating layer 2 to form a cover plate with a specific shape;

[0150] Step S400: splice and assemble the multiple processed cover plates according to the design requirements to form the shell of the speaker device.

[0151] When the shell of the speaker equipment is mainly a flat structure without complex curved shapes, such as Figures 1 to 4 The housing body 1 shown can be manufactured by using steps S100 to S400 in this example of the present application. The specific analysis is as follows.

[0152] Step S100 is to provide a transparent substrate 101. This step is the starting point of the preparation process. The transparent substrate 101 is used as the basic material for making the housing body 1 (that is, the material for making the cover plate). Its transparency is the key to the subsequent formation of the grating effect.

[0153] The transparent substrate 101 material includes glass, transparent plastic, carbon fiber composite material, etc. That is to say, the transparent substrate 101 is a glass substrate or a plastic plate, and of course it can also be a carbon fiber composite substrate. Among the substrates of these materials, the glass substrate cannot be bent after the grating layer 2 is printed based on material properties, and it can only be used as a planar structural member. The plastic substrate can be bent to a certain extent after the grating layer 2 is formed, so that the shell body 1 with a certain curvature can be manufactured.

[0154] Step S200 is to form a grating layer 2 on the transparent substrate 101. The grating layer 2 is formed on the transparent substrate 101 by a specific process such as printing or laser engraving, and is a line pattern composed of at least one element of straight lines, curves and broken lines in a densely arranged manner. These line patterns can produce unique light reflection and refraction effects, thereby giving the shell a unique visual effect.

[0155] In the line pattern, parameters such as line accuracy, line width, and the space between two lines can be controlled according to design requirements to achieve different grating effects.

[0156] Step S300 is to process the transparent substrate 101 with the grating layer 2 to form a cover plate with a specific shape. After the grating layer is formed on the transparent substrate 101, the transparent substrate needs to be further processed, such as cutting, hot bending, etc., to form a cover plate with a specific shape that meets the requirements of the shell of the speaker device. This step ensures that the overall design and structure of the shell and the speaker device match.

[0157] Step S400 is to splice and assemble the multiple processed cover plates according to the design requirements to form the shell of the speaker device. In other words, finally, the multiple processed cover plates are spliced ​​and assembled according to the design requirements to form a complete shell of the speaker device.

[0158] The splicing and assembly methods can be customized according to specific design requirements, such as using a splicing push-pull structure to ensure the stability and easy disassembly of the shell.

[0159] According to an embodiment of the present application, a method for preparing a housing of a speaker device is provided, the method comprising the following steps S500 to S800:

[0160] Step S500, providing a transparent substrate 101 and a film 21;

[0161] Step S600: processing the transparent substrate 101 to form a cover plate of a specific shape;

[0162] Step S700, see Figure 7 , forming a line pattern on the film 21 by printing or laser engraving, thereby forming a grating layer 2;

[0163] Step S800, directly attaching or injection molding a grating layer 2 on the cover plate; wherein the grating layer 2 is a line pattern composed of at least one element of straight lines, curves and broken lines in a densely arranged manner;

[0164] Step S900: splice and assemble a plurality of processed cover plates with grating layers 2 according to design requirements to form a housing of a sound box device.

[0165] When the shape of the shell of the speaker device is relatively complex, for example, having many curved or arcuate structures, the grating layer 2 can be firstly made on a diaphragm, and then the diaphragm is attached to the surface of the processed cover plate or the shell body 1.

[0166] Step S500 is to provide a transparent substrate 101 and a film. In this step, the transparent substrate 101 is provided as a base material for the shell and a base material for forming the grating layer 2. The film 21 is, for example, a PET film.

[0167] Step S600 is to process the transparent substrate 101 to form a cover plate of a specific shape.

[0168] Step S700 is to form a line pattern on the film 21 , that is, to form a grating layer 2 .

[0169] Step S800 is to arrange the grating layer 2 manufactured in step S700 on the processed cover plate by means of attachment or injection molding.

[0170] Different from step S200 and step S300 in the above example, in this example of the present application, the transparent substrate 101 is first processed into a cover plate and then the grating layer 2 is attached or injection molded. However, step S200 and step S300 in the above example are to first form the grating layer 2 on the transparent substrate 101 and then process it into a cover plate.

[0171] In step S800 of this example of the present application, the attachment method may be a process of gluing after printing a line pattern on the film 21. For example, a glue layer of a certain thickness may be provided on the back of the film 21, and the glue layer is used to bond with the cover plate or the housing body.

[0172] Optionally, the thickness of the glue layer on the back of the diaphragm 21 is 0.01mm-0.02mm. There is a protective film on the back of the glue layer to protect the cured glue layer. When it is necessary to bond with the material, just peel off the protective film and stick it on the cover or the shell body.

[0173] Step S900 is to splice and assemble a plurality of processed cover plates with grating layers 2 to form a complete sound box device housing, see Figures 1 to 4 .

[0174] Compared with the above example, this example of the present application is different in processing order, but it can also achieve the application of grating effect on the shell of the speaker device.

[0175] Both examples of this application provide methods for preparing the housing of a speaker device, and the application of the grating effect on the housing of the speaker device is achieved through different processing sequences and processes. Both methods can prepare the housing of the speaker device with unique visual effects and light refraction effects, and the prepared housings have good structural stability and easy disassembly. The specific method to be selected can be determined based on actual production requirements and process conditions.

[0176] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
