Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0028] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

It should also be understood that additional or alternative steps may be used.
[0029] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

Therefore, the example term "below" can include both upper and lower orientations.
[0031] In the field of optimizing the mechanical performance of the side ribs of the woofer unit basket, in order to ensure that the product (such as large magnetic circuit woofers and subwoofers) has sufficient structural strength and meets the mechanical test requirements of customers, the current solidified structural design of the side ribs of the basket meets the strength requirements of the large magnetic circuit system, but the mass is redundant (the mass of the side ribs of the basket is greater than 50% of the total mass of the basket), resulting in a large weight of the basket and the speaker itself.
[0032] Figure 1 A schematic diagram of a basin stand structure according to a first embodiment of the present invention is shown. Figure 1 As shown, this utility model proposes a basket frame structure and a speaker. The basket frame structure of this utility model includes a bottom wall 10 and a side wall. The side wall is a ring structure and surrounds the outer periphery of the bottom wall 10. An annular fixing part 22 is provided on the outer periphery of the side wall. The annular fixing part 22 and the bottom wall 10 are spaced apart along the axial direction of the annular structure. The side wall includes a skeleton part 21, and the skeleton part 21 has a hollow structure.
[0033] By using the basket frame structure in this technical solution, the bottom wall 10 is used to support and fix other components of the speaker, the annular fixing part 22 is used to connect the basket frame structure to the speaker, the annular structure of the side wall is used to accommodate some speaker components, and the skeleton part 21 has a hollow structure, which can reduce the mass of the skeleton part 21, thereby achieving the purpose of lightweighting the basket frame structure and the speaker. In addition, the hollow structure can also improve the air permeability of the side wall, achieving dual optimization of lightweighting and air permeability of the side wall.
[0034] In addition, the sidewalls in this embodiment are made of thermoplastic carbon fiber, which can reduce the weight of the overall basket structure while ensuring its own strength, thus achieving the goal of lightweighting the basket structure and the speaker.
[0035] Specifically, in this embodiment, carbon fiber itself possesses high strength and high modulus, with tensile strength and stiffness exceeding those of traditional metal materials. When combined with thermoplastic resin, the resulting composite material exhibits superior strength, rigidity, and toughness. Furthermore, thermoplastic carbon fiber materials have low density and are lightweight, significantly reducing weight compared to traditional metal materials. This allows for a substantial reduction in the weight of the sidewalls and the frame structure, fulfilling the lightweight requirements of the frame structure.
[0036] In some embodiments of this utility model, such as Figure 2 As shown, the sidewall includes a frame portion 21, which is disposed between the bottom wall 10 and the annular fixing portion 22. Both ends of the frame portion 21 are connected to the annular fixing portion 22 and the bottom wall 10, respectively. The frame portion 21 has a hollow structure 211 inside. In this embodiment, the sidewall can be an annular structure, connected to the bottom wall 10 and the annular fixing portion 22 along the axial direction of the annular structure. The sidewall is used to accommodate the sound-emitting component of the loudspeaker.
[0037] Specifically, in this embodiment, such as Figure 4 As shown, the sidewall has a hollow structure 211, which can improve the breathability of the sidewall. Combined with the thermoplastic carbon fiber material of the sidewall, it can achieve dual optimization of sidewall lightweighting and breathability.
[0038] Specifically, in this embodiment, the sidewall includes multiple supporting ribs, which enclose a receiving space. Within this space, several intersecting horizontal and vertical ribs, or ribs of triangular, circular, or other irregular shapes, are arranged. Two or more ribs form a perforated structure 211. These ribs not only enhance the overall rigidity of the overall frame 21 but also form the perforated structure 211, improving the air permeability of the sidewall.
[0039] In some embodiments of this utility model, such as Figure 1 As shown, multiple skeleton parts 21 are provided, and the multiple skeleton parts 21 are spaced apart along the circumference of the annular structure. In this embodiment, there are multiple skeleton parts 21, which are arranged along the circumference of the annular structure and together form an annular structure. Compared with the structure of a single skeleton part 21, the annular structure of multiple skeleton parts 21 can further reduce the weight of the sidewalls, and further achieve the lightweighting of the basin stand. Moreover, the spaced arrangement between adjacent skeleton parts 21, combined with the hollow structure 211, can further improve the air permeability.
[0040] In some embodiments of this utility model, such as Figure 1As shown, the sidewall also includes a reinforcing ring 23, which is located within the annular structure and positioned between the bottom wall 10 and the annular fixing portion 22. The outer periphery of the reinforcing ring 23 is connected to a plurality of skeleton portions 21. In this embodiment, the reinforcing ring 23 is connected to the inner side of the plurality of skeleton portions 21, enabling the plurality of skeleton portions 21 to be connected together, so that the sidewall forms a whole and improves the overall strength of the sidewall.
[0041] Specifically, the reinforcing ring 23 can also be connected to only one skeleton part 21, such as Figure 3 As shown.
[0042] Specifically, in this embodiment, multiple reinforcing rings 23 can be provided, and the multiple reinforcing rings 23 are spaced apart along the axial direction of the annular structure. Each reinforcing ring 23 can connect multiple skeleton parts 21 together, and the multiple reinforcing rings 23 can further improve the overall strength of the sidewall and improve reliability.
[0043] In some embodiments of this utility model, such as Figure 1 As shown, the bottom wall 10 has a first mounting hole 11, which is arranged along the axial direction of the annular structure. In this embodiment, the first mounting hole 11 can connect the bottom wall 10 to the first component of the speaker, thereby fixing the first component.
[0044] In some embodiments of this utility model, such as Figure 1 As shown, the annular fixing part 22 has a second mounting hole 221, which is arranged along the axial direction of the annular structure. In this embodiment, the second mounting hole 221 can connect the annular fixing part 22 to the second component of the speaker, thereby fixing the second component.
[0045] In some embodiments of this utility model, such as Figure 1 As shown, multiple first mounting holes 11 are provided, and the multiple first mounting holes 11 are spaced apart circumferentially along the bottom wall 10. In this embodiment, the provision of multiple first mounting holes 11 can improve the connection strength and reliability of the first component.
[0046] Specifically, in this embodiment, such as Figure 1 As shown, multiple second mounting holes 221 are provided, and these multiple second mounting holes 221 are spaced apart circumferentially along the annular structure. The provision of multiple second mounting holes 221 can improve the connection strength and reliability of the second component.
[0047] In some embodiments of this utility model, the bottom wall 10 and the annular fixing part 22 are thermoplastic carbon fiber parts. In this embodiment, by making both the bottom wall 10 and the annular fixing part 22 thermoplastic carbon fiber parts, together with the upper side wall, the lightweight effect of the basin frame structure can be further improved.
[0048] In some embodiments of this utility model, the basin frame structure is integrally manufactured by 3D printing. In this embodiment, 3D printing can easily realize internal hollow structures 211 (such as honeycomb or lattice structures) or topology optimization designs (such as biomimetic bone structures) that are difficult to process using traditional methods. This facilitates the processing of the hollow structure 211 of the sidewalls in this application. In this embodiment, only the sidewalls can be integrally formed by 3D printing.
[0049] Specifically, 3D printing allows for one-piece molding, reducing stress concentration and fatigue risks associated with connection points (such as welding and bolts). This makes the basin frame structure in this invention more integrated, improving its stability and reliability.
[0050] This invention, based on the optimization of 3D printing technology, can break through the limitations of traditional manufacturing processes and realize the multi-dimensional biomimetic skeleton reconstruction of the speaker basket structure. Through a highly flexible integrated molding solution, its lightweight level is improved by more than 50% compared with conventional injection molding / die casting processes, and a hollow structure 211 is constructed simultaneously to achieve dual optimization of breathability and lightweight.
[0051] Furthermore, the basin frame structure is made of thermoplastic carbon fiber with a density of 1.56 g / cm³, achieving a 50% or more lightweight improvement in 3D carbon fiber printing compared to conventional injection molding / die casting processes. Secondly, the basin frame structure's ventilation system offers over 56% better breathability than traditional solutions. Thirdly, while ensuring product lightweighting, the basin frame structure allows for adjustments to the multi-dimensional biomimetic skeletal framework, ensuring the product's strength meets customer requirements and various mechanical testing standards.
[0052] This invention also proposes a loudspeaker having the aforementioned frame structure.
[0053] By using the speaker frame structure in this technical solution, the bottom wall 10 is used to support and fix other speaker components, the annular fixing part 22 is used to connect the frame structure to the speaker, and the annular structure of the side wall is used to accommodate some speaker components. Furthermore, the side wall is made of thermoplastic carbon fiber, which can reduce the weight of the overall frame structure while ensuring its own strength, thereby achieving the goal of lightweight frame structure and speaker.
[0054] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
