Description

Technical Field

[0001] This invention relates to the field of acoustic equipment technology, specifically to a pre-assembled acoustic component, its U-shaped support structure, and an integration method. Background Technology

[0002] As a transducer that converts electrical signals into sound signals, loudspeakers are widely used in consumer electronics, car audio, professional sound reinforcement and other fields. Their core vibration system usually consists of a frame, spider, voice coil, diaphragm and connecting wires. Figure 1 This is a schematic diagram of the structure of a traditional loudspeaker. Figure 1 As shown, traditional loudspeaker vibration systems generally employ a component stacking assembly process. First, a magnetic circuit system is constructed using a T-iron and magnets to provide a stable magnetic field for the voice coil. Next, the voice coil, wound on a Whooper skeleton, is precisely installed in the gap of the magnetic circuit to ensure the accuracy of electromagnetic conversion. Then, a spider is connected to use its elasticity to limit diaphragm displacement and buffer vibration. The diaphragm is then fixed to the frame, which integrates the various components to form a stable structure. Finally, a dust cover is installed to protect the internal precision components from contamination.

[0003] The aforementioned traditional solutions, despite long-term industry application, still suffer from several insurmountable technical defects: 1. Low assembly precision and poor consistency: The spider, voice coil and diaphragm are stacked layer by layer on the frame. Each layer bonding will produce cumulative tolerance. In particular, the concentricity of the voice coil in the magnetic gap cannot be effectively guaranteed, which can easily cause defects such as coil contact and under-contact. This problem is particularly prominent in high-power and high-performance loudspeaker products, which directly leads to a decrease in product yield and reliability.

[0004] 2. Unrestricted wire layout makes automated production difficult: Wire routing is a "post-process" and has no dedicated physical limiting structure. It is usually suspended above the bobbin, which not only makes the wires prone to breakage during vibration, but also makes it difficult for robotic arms to complete precise wire routing and fixing in a complex three-dimensional space. This seriously restricts the improvement of production efficiency and keeps labor costs high.

[0005] 3. Insufficient heat dissipation: When the voice coil is inserted into the inner ring of the spider, the spider will obstruct the convection path of the hot air around the voice coil. On the one hand, this will aggravate the further temperature rise of the magnetic circuit and the voice coil. On the other hand, long-term insufficient heat dissipation will cause the spider material to soften, age faster, and reduce the centering accuracy.

[0006] 4. In traditional processes, the conductors are easily damaged during synchronous hot pressing with the spring, leading to abnormal impedance, easy oxidation and burnout, and the risk of short circuit.

[0007] In view of this, the present invention provides a pre-assembled acoustic component, its U-shaped support structure, and an integration method to at least partially solve the above-mentioned technical problems. Summary of the Invention

[0008] This invention addresses the technical problems existing in the prior art by providing a pre-assembled acoustic component, its U-shaped support structure, and an integration method.

[0009] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A U-shaped support structure for a pre-assembled acoustic component includes a U-shaped bottom and a U-shaped sidewall extending upward from the outer periphery of the U-shaped bottom; wherein, a wire guide channel is provided on the U-shaped sidewall, the wire guide channel being used to restrict the routing path of the lead wires from the voice coil in the acoustic component.

[0010] In some embodiments, the wire guide channel is any one or a combination of a groove structure formed on the U-shaped sidewall or a perforated structure penetrating the thickness of the U-shaped sidewall, and the wire guide channel extends a predetermined length along the height and circumferential directions of the U-shaped sidewall.

[0011] In some embodiments, the U-shape has an opening at the center of its bottom.

[0012] In some embodiments, the U-shaped support structure includes a first U-shaped support and a second U-shaped support, the first and second U-shaped supports being nested together to confine the elastic wave between the first and second U-shaped supports.

[0013] In some embodiments, the U-shaped bracket is made of high-temperature resistant engineering plastic or a material similar to or the same as that used in the sponge.

[0014] The present invention also provides a pre-assembled acoustic component, comprising the U-shaped support structure as described above, as well as a spider, a voice coil, a diaphragm, and a wire; wherein: The inner ring of the spring is fixed to the top end face of the U-shaped bracket; The voice coil is connected to the inner ring of the spider. The edge of the diaphragm overlaps and is fixed to the top end face of the U-shaped sidewall; After the wire is led out from the voice coil, it is confined within the wire guide channel and extends along the channel to the outside of the U-shaped bracket.

[0015] In some embodiments, in the pre-assembled acoustic assembly, the U-shaped support structure includes a first U-shaped support and a second U-shaped support, wherein a wire guide channel is provided on the side wall of the second U-shaped support; wherein... The inner ring of the spring wave is fixed to the top end face of the first U-shaped bracket; The voice coil is connected to the inner ring of the spider. After the wire is led out from the voice coil, it is confined within the wire threading channel on the side wall of the second U-shaped bracket and extends along the channel to the outside of the U-shaped bracket; The second U-shaped bracket is nested with the first U-shaped bracket, confining the elastic wave and the wire between the first and second U-shaped brackets; The edge of the diaphragm overlaps and is fixed to the top end face of the side wall of the nested U-shaped bracket.

[0016] In some embodiments, the U-shaped bracket, together with the spider, the voice coil, and the diaphragm, constitutes an independent modular unit, which is detachably assembled into the speaker basket.

[0017] The present invention also provides an integration method for a pre-assembled acoustic component, based on the U-shaped support structure described above or the pre-assembled acoustic component described above, the integration method comprising the following steps: S1: Fix the inner ring of the spring to the top end face of the U-shaped bracket; S2: Connect and fix the voice coil to the inner ring of the spider; S3: Press or pass the wire leading from the voice coil into the wire passing channel on the U-shaped side wall to complete the wire limiting; S4: Overlap and fix the edges of the diaphragm to the top end face of the U-shaped sidewall to form a pre-assembled acoustic component; S5: Place the pre-assembled acoustic components into a hot press and press them.

[0018] In some embodiments, the integration method includes a U-shaped support structure comprising a first U-shaped support and a second U-shaped support, wherein a wire guide channel is provided on the side wall of the second U-shaped support; the integration method includes the following steps: S1: Fix the inner ring of the spring to the top end face of the first U-shaped bracket; S2: Connect and fix the voice coil to the inner ring of the spider; S3: Press or thread the wire leading from the voice coil into the wire threading channel on the side wall of the second U-shaped bracket to complete the wire limiting; S4: The second U-shaped bracket is nested with the first U-shaped bracket, and the spring and the wire are confined between the first and second U-shaped brackets; S5: Overlap and fix the edge of the diaphragm to the top end face of the side wall of the nested U-shaped bracket to form a pre-assembled acoustic component; S6: Place the pre-assembled acoustic components into a hot press and press them.

[0019] In one or more of the above specific embodiments, the pre-assembled acoustic component, its U-shaped support structure, and integration method provided by the present invention have at least the following technical effects: This invention systematically overcomes the structural defects of existing technologies by changing the traditional method of stacking speaker components, and achieves synergistic optimization of structural design and process sequence. Specifically: Assembly precision and product yield are significantly improved. In traditional processes, the spider, voice coil, and diaphragm are bonded to the frame layer by layer. Each assembly step introduces positioning errors, which, when accumulated over multiple layers, directly lead to loss of voice coil concentricity. This invention uses the U-shaped bottom and sidewalls of the U-shaped bracket as a unified assembly benchmark. The spider, voice coil, and diaphragm are all pre-positioned and fixed on the bracket, eliminating the tolerance transfer path of layer-by-layer stacking. Structurally, this ensures the coaxial relationship between the voice coil and the magnetic gap, fundamentally avoiding defects caused by eccentricity such as coil contact and underlayment. As a result, product consistency and yield are guaranteed in high-power scenarios.

[0020] Standardized wire layout supports fully automated mass production. In traditional solutions, wire routing is a post-processing step without dedicated constraint structures. The suspended state of the wires forces robotic arms to grasp, arrange, and fix the flexible wires in a complex three-dimensional space, making the operation extremely difficult. This invention integrates a wire threading channel on the U-shaped sidewall, completely confining the wires within a preset physical path. This transforms the originally non-standard flexible wire management into a standardized "threading / clamping" action, significantly reducing the operational complexity and control difficulty of automated equipment. It provides a structural foundation for fully automated production lines and avoids the risks of wire breakage and short circuits caused by disordered swaying.

[0021] The client assembly process is significantly simplified, reducing overall costs. Traditional speaker assembly requires multiple steps of bonding, positioning, and wiring, resulting in a lengthy process that relies heavily on manual labor. This invention integrates disparate vibration system components into independent functional modules. The client only needs to perform two steps—"integrating the entire frame + external wire bonding"—to complete the single-unit assembly, significantly shortening the production cycle, reducing reliance on skilled workers, and lowering the investment in fixtures and equipment. This achieves cost reduction from multiple dimensions, including time, manpower, and equipment. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0033] Reference Figures 2-8 The U-shaped support structure of the pre-assembled acoustic component provided by the present invention includes a U-shaped bottom 6 and a U-shaped sidewall 7 extending upward from the outer periphery of the U-shaped bottom 6; wherein, a wire guide channel 8 is provided on the U-shaped sidewall 7, and the wire guide channel 8 is used to restrict the routing path of the lead wires of the voice coil in the acoustic component. Figure 3This is the front view of the U-shaped bracket. The U-shaped bottom and sidewalls form a closed load-bearing structure, providing a unified assembly benchmark for the spider, voice coil, and diaphragm. At the same time, the sidewalls integrate wire guide channels, structurally replacing the traditional unrestrained suspended wiring method. This fundamentally solves the industry pain points of messy wire arrangement, easy breakage, and difficulty in automation, and serves as the basic carrier of the entire pre-assembly solution.

[0034] Specifically, the wire guide channel 8 is either a groove structure formed on the U-shaped sidewall 7 or a perforation structure penetrating the thickness of the U-shaped sidewall 7, or a combination thereof, and the wire guide channel 8 extends a predetermined length along the height and circumference of the U-shaped sidewall 7. Designing the wire guide channel as a groove or a perforation, and extending a predetermined length along the height and circumference of the sidewall, accommodates the routing requirements of wires of different lengths and is compatible with voice coil structures of different winding methods. The groove structure facilitates visual recognition and wire insertion operations by automated equipment, while the perforation structure further enhances the limiting stability of the wire, preventing the wire from coming out during vibration and improving product reliability.

[0035] Furthermore, the U-shaped bottom 6 has an opening structure 9 in the center. The open structure of the U-shaped bottom facilitates heat dissipation of the voice coil, reduces heat retention in the magnetic circuit and voice coil, delays the softening and aging of the spider material at high temperatures, and ensures the centering accuracy of the spider. The top of the U-shaped sidewall 7 also has an outer edge 10 along the circumference for supporting and fixing the spider. Figure 2 This is a schematic diagram of the U-shaped support and the elastic wave. Figure 4 This is a 3D view of the U-shaped bracket and the spring after assembly.

[0036] In some preferred embodiments, the U-shaped support structure includes a first U-shaped support and a second U-shaped support, the first and second U-shaped supports being nested together to confine the elastic wave between the first and second U-shaped supports. Figure 6 This is a schematic diagram of the double-layer U-shaped bracket and the spider. Fixing the spider between the double-layer U-shaped brackets provides a more stable platform, thereby increasing its stability under high-power, high-intensity vibrations. Additionally, the voice coil leads can be confined within the double-layer U-shaped brackets, preventing damage to the leads during subsequent synchronous hot-pressing with the spider, thus avoiding impedance abnormalities, oxidation burnout, short circuits, and other issues.

[0037] The aforementioned U-shaped bracket can be made of high-temperature resistant engineering plastics or materials similar to or the same as those used in sponges. High-temperature resistant engineering plastics offer excellent dimensional stability and lightweight advantages, balancing structural strength, temperature resistance, and environmental compliance, making them suitable for large-scale mass production. High-temperature resistant engineering plastics, such as polyphenylene sulfide (PPS) and liquid crystal polymers (LCP), possess excellent high-temperature resistance, dimensional stability, and lightweight characteristics. They can be directly injection molded into an integrated structure with wire guide channels, suitable for large-scale mass production, and meeting environmental regulations. The U-shaped bracket is manufactured using materials similar to or the same as those used in sponges to match their coefficient of thermal expansion, thereby avoiding pre-assembly accuracy failures caused by deformation differences due to temperature variations during hot pressing or high-power operation, ensuring pre-assembly accuracy.

[0038] The present invention also provides a pre-assembled acoustic component, including the U-shaped support structure as described above, a spider 2, a voice coil 3, a diaphragm 4, and a wire 5; wherein, the inner ring of the spider 2 is fixed to the top end face of the U-shaped support 1; the voice coil 3 is connected to the inner ring of the spider 2; the edge of the diaphragm 4 overlaps and is fixed to the top end face of the U-shaped sidewall 7; the wire 5, after being led out from the voice coil 3, is confined within the wire guide channel 8 and extends along the channel to the outside of the U-shaped support 1. Subsequently, the wire 5 is fixed to the spider 2 by means of perforation or adhesive fixation. Figure 5 This is a three-dimensional top view of the pre-assembled acoustic component. By defining the fixed positional relationship between the spider, voice coil, diaphragm, and U-shaped support, as well as the limiting relationship of the wires within the channel, the dispersed independent parts are integrated into an indivisible functional whole. Compared with traditional component stacking, this structure eliminates the cumulative tolerance of layer-by-layer assembly, ensures the concentricity of the voice coil from the physical connection level, and achieves the standardization of wire layout, providing a structural prerequisite for subsequent automated assembly.

[0039] In some preferred embodiments, in the pre-assembled acoustic assembly, the U-shaped support structure includes a first U-shaped support and a second U-shaped support, with a wire guide channel provided on the side wall of the second U-shaped support; wherein, the inner ring of the spider 2 is fixed to the top end face of the first U-shaped support; the voice coil 3 is connected to the inner ring of the spider 2; the wire 5, after being led out from the voice coil 3, is confined within the wire guide channel 8 on the side wall of the second U-shaped support and extends along the channel to the outside of the U-shaped support; the second U-shaped support is nested with the first U-shaped support, confining the spider 2 and the wire 5 between the first and second U-shaped supports; the edge of the diaphragm 4 overlaps and is fixed to the top end face of the side wall of the nested U-shaped support. Figure 7 This is a structural diagram of a pre-assembled acoustic assembly including a double-layer U-shaped support. Figure 8 This is a top view of the pre-assembled acoustic assembly, including the double-layer U-shaped support.

[0040] The aforementioned U-shaped bracket, together with the spider 2, the voice coil 3, and the diaphragm 4, constitutes an independent modular unit. This modular unit can be detachably assembled into the speaker basket. By defining the U-shaped bracket and each component as an independent modular unit, the client no longer needs to assemble the vibration system in steps. Instead, the core structure assembly can be completed in a single step: the entire assembly is installed into the basket. This significantly simplifies the client's process flow, reduces reliance on manual skills, and minimizes the risk of component damage during assembly.

[0041] The present invention also provides an integration method for a pre-assembled acoustic component, based on the U-shaped support structure described above or the pre-assembled acoustic component described above, the integration method comprising the following steps: S1: Fix the inner ring of the spindle 2 to the top end face of the U-shaped bracket 1; S2: Connect and fix the voice coil 3 to the inner ring of the spider 2; S3: Press or pass the wire 5 led out from the voice coil 3 into or through the wire passage 8 on the U-shaped side wall 7 to complete the wire limiting; S4: Overlap and fix the edge of the diaphragm 4 to the top end face of the U-shaped sidewall 7 to form a pre-assembled acoustic component; S5: Place the pre-assembled acoustic components into the hot press for hot pressing. Set the parameters: temperature (150-220℃), time (10-40 seconds), and pressure (0.1-1Mpa); start the hot press to tightly bond the U-shaped bracket, spider, voice coil, and diaphragm through hot pressing, thereby improving structural strength and assembly efficiency.

[0042] In some preferred embodiments, in the integration method of the pre-assembled acoustic components, the U-shaped bracket structure includes a first U-shaped bracket and a second U-shaped bracket, and the second U-shaped bracket has a wire guide channel on its side wall; the integration method includes the following steps: S1: Fix the inner ring of the spring wave 2 to the top end face of the first U-shaped bracket; S2: Connect and fix the voice coil 3 to the inner ring of the spider 2; S3: Press or thread the wire 5 led out from the voice coil 3 into the wire threading channel 8 on the side wall of the second U-shaped bracket to complete the wire limiting; S4: The second U-shaped bracket is nested with the first U-shaped bracket, and the elastic wave 2 and the wire 5 are confined between the first and second U-shaped brackets; S5: Overlap and fix the edge of the diaphragm 4 to the top end face of the side wall of the nested U-shaped bracket to form a pre-assembled acoustic component; S6: Place the pre-assembled acoustic components into the hot press for hot pressing. Set the parameters: temperature (150-220℃), time (10-40 seconds), and pressure (0.1-1Mpa); start the hot press to tightly bond the first and second U-shaped brackets, spider, voice coil, and diaphragm through hot pressing, thereby improving structural strength and assembly efficiency.

[0043] This invention completely changes the assembly logic of stacked components by first fixing the spider and voice coil, then introducing the wires to the channel, and finally assembling the diaphragm. This is achieved by changing the traditional post-processing of wiring to pre-processing. Each step is completed on a flat support platform, avoiding the complexity of three-dimensional space operation and providing a feasible process path for fully automated production lines.

[0044] Thus, after completing the pre-assembled acoustic components, the speaker unit assembly can be completed simply by installing the entire component into the speaker frame and completing the external wire bonding process. By limiting the pre-assembled components to only two steps—installing them into the frame and bonding the wires—the traditional multi-step, lengthy assembly process is compressed into extremely simple steps, significantly reducing production time and equipment investment for the client. Simultaneously, it reduces quality fluctuations caused by multiple manual operations, improving batch consistency of the final product.

[0045] In one or more of the above specific embodiments, the pre-assembled acoustic component, its U-shaped support structure, and integration method provided by the present invention have at least the following technical effects: This invention systematically overcomes the structural defects of existing technologies by changing the traditional method of stacking speaker components, and achieves synergistic optimization of structural design, process sequence, and material properties. Specifically: Assembly precision and product yield are significantly improved. In traditional processes, the spider, voice coil, and diaphragm are bonded to the frame layer by layer. Each assembly step introduces positioning errors, which, when accumulated over multiple layers, directly lead to loss of voice coil concentricity. This invention uses the U-shaped bottom and sidewalls of the U-shaped bracket as a unified assembly benchmark. The spider, voice coil, and diaphragm are all pre-positioned and fixed on the bracket, eliminating the tolerance transfer path of layer-by-layer stacking. Structurally, this ensures the coaxial relationship between the voice coil and the magnetic gap, fundamentally avoiding defects caused by eccentricity such as coil contact and underlayment. As a result, product consistency and yield are guaranteed in high-power scenarios.

[0046] Standardized wire layout supports fully automated mass production. In traditional solutions, wire routing is a post-processing step without dedicated constraint structures. The suspended state of the wires forces robotic arms to grasp, arrange, and fix the flexible wires in a complex three-dimensional space, making the operation extremely difficult. This invention integrates a wire threading channel on the U-shaped sidewall, completely confining the wires within a preset physical path. This transforms the originally non-standard flexible wire management into a standardized "threading / clamping" action, significantly reducing the operational complexity and control difficulty of automated equipment. It provides a structural foundation for fully automated production lines and avoids the risk of breakage and short circuits caused by disordered wire movement.

[0047] The client assembly process is significantly simplified, reducing overall costs. Traditional speaker assembly requires multiple steps of bonding, positioning, and wiring, resulting in a lengthy process that relies heavily on manual labor. This invention integrates disparate vibration system components into independent functional modules. The client only needs to perform two steps—"integrating the entire frame + external wire bonding"—to complete the single-unit assembly, significantly shortening the production cycle, reducing reliance on skilled workers, and lowering the investment in fixtures and equipment. This achieves cost reduction from multiple dimensions, including time, manpower, and equipment.

[0048] To facilitate understanding, the following will be combined with... Figures 2-8 The overall technical solution provided by the present invention is described through a complete embodiment.

[0049] In this embodiment, the acoustic component, taking a loudspeaker as an example, includes a pre-assembled loudspeaker unit structure consisting of a spider body, a first U-shaped bracket, a second U-shaped bracket, a voice coil, a wire, and a diaphragm. The first and second U-shaped brackets are the same or similar in shape and size, allowing them to be nested together; each has an opening at the center of its U-shaped bottom, and each has an outer edge at the top of its U-shaped sidewall, with a notch on the outer edge. The notches of the first and second U-shaped brackets correspond perfectly, forming a complete outlet for the wire to exit the U-shaped bracket. The spider body has an inner edge and an outer edge; the inner edge is used to connect to the voice coil frame, and the outer edge is used to connect to the frame; the spider body has an opening at the center, and the cross-section (radial section) of the spider is irregularly corrugated, composed of multiple concentric ring-shaped peaks and troughs arranged alternately.

[0050] The pre-assembled speaker unit structure, consisting of the spider body, first and second U-shaped brackets, voice coil, wires, and diaphragm, specifically includes: The inner ring of the spring is fixed to the top end face of the first U-shaped bracket; The voice coil is connected to the inner ring of the spider; After the wire is led out from the voice coil, it is neatly routed inside the U-shaped bracket through the wire guide channel on the side wall of the second U-shaped bracket. The second U-shaped bracket is nested with the first U-shaped bracket, confining the spring and the wire between the first and second U-shaped brackets; align the notches on the outer edges of the first and second U-shaped brackets with the wire interface to ensure that the notch positions on the two U-shaped brackets correspond perfectly, so that the notch completely covers the wire. This can prevent the wire from being pulled and broken during hot pressing and ensure the wire impedance. The edge of the diaphragm overlaps and is fixed to the top end face of the side wall of the nested U-shaped bracket.

[0051] The integration method of the above-mentioned pre-assembled acoustic components is as follows: S1: Place the first U-shaped bracket into the bottom positioning groove of the winding mold, ensuring that the U-shaped bracket is aligned with the positioning hole / slot of the mold, and fix it with slight pressure (to prevent displacement in subsequent operations). Place the bobbin on top of the first U-shaped bracket and adjust its position: make the center of the bobbin coincide with the center of the U-shaped bracket (to avoid eccentricity that could lead to vibration imbalance). Confirm that the corrugation direction of the bobbin is consistent with the winding direction of the U-shaped bracket (the corrugation direction affects the elastic restoring force of the bobbin).

[0052] S2: Connect and fix the voice coil to the inner coil of the spider. Take the voice coil (the coil wound with wire), insert one end of the wire into the pre-reserved winding port of the U-shaped bracket, and evenly wind it along the edge of the spider and the U-shaped bracket (such as by hand winding, soldering, crimping, or gluing). Ensure the connection is firm and not loose, and avoid the coil being loose or too tight. After winding, cut off the excess wire with scissors.

[0053] S3: Take the second U-shaped bracket (the same size as the first U-shaped bracket) and align its notch with the wire interface. Ensure the notches of the two U-shaped brackets are perfectly aligned, completely covering the wire (to prevent exposed wires from causing short circuits or damage). Adjust the position of the second U-shaped bracket so that it is parallel to the first U-shaped bracket and centered, then secure it with light pressure. Continue winding and tidying the wire ends. After winding, use pliers again to tidy the wire ends, confirming that they are securely fixed and not loose.

[0054] S4: Overlap the edge of the diaphragm onto the top end face of the U-shaped sidewall (the top of the second U-shaped bracket), and adjust the position of the diaphragm to align it with the U-shaped sidewall.

[0055] S5: Place the pre-assembled components into the hot press and set the parameters: temperature (150-220℃), time (10-40 seconds), and pressure (0.1-1 MPa). Start the hot press to tightly bond the U-shaped bracket, spider, voice coil, and diaphragm through hot pressing, improving structural strength and assembly efficiency.

[0056] The biggest difference between the technical solution provided by this invention and existing technologies lies in the pioneering use of a U-shaped bracket as an integrated carrier, transforming "post-assembly" into "pre-assembly." Specifically: U-shaped bracket body design: This invention designs an integrated bracket structure including first and second U-shaped brackets. The bracket material must meet the requirements of lightweight and temperature resistance. Furthermore, on the second U-shaped bracket, wire guide channels with specific orientations, such as grooves or perforations, are integrally formed or machined.

[0057] The connection relationships and integration order of the various components have changed: First, fix the inner ring of the spinner to the inner side of the top end face of the first U-shaped bracket; Connect the voice coil to the inner coil of the spider; Press or thread the lead wire from the voice coil into the lead wire channel on the side wall of the second U-shaped bracket; The second U-shaped bracket is nested with the first U-shaped bracket, and the spring and the wire are confined between the first and second U-shaped brackets; the notches on the outer edges of the first and second U-shaped brackets are aligned with the wire interface to ensure that the notch positions on the two U-shaped brackets are completely corresponding, so that the notch completely covers the wire and completes the wire confinement; The edges of the diaphragm are overlapped and fixed to the top end face of the side wall of the nested U-shaped bracket; During the wire integration process, at the same time or before the voice coil is connected to the diaphragm, the wire is led out from the voice coil and directly pressed into or passed through the wire passing channel on the second U-shaped bracket. The wire's direction is completely defined by the wire passing channel. Finally, place the pre-assembled components into the hot press; set the parameters: temperature (150-220℃), time (10-40 seconds), and pressure (0.1-1Mpa); start the hot press to tightly bond the U-shaped bracket, spider, voice coil, and diaphragm through hot pressing, thereby improving structural strength and assembly efficiency.

[0058] Through the above steps, before placing this component with the U-shaped bracket into the basket, the spider, voice coil, diaphragm, and wires have formed a highly integrated "pre-assembled acoustic component (module)".

[0059] In combination with the above technical solutions, the beneficial effects of the technical solutions provided by the present invention compared with the prior art are as follows: (1) Significantly improve assembly accuracy and yield: Since the spider, voice coil and diaphragm are pre-positioned and bonded on the unified reference platform of the U-shaped bracket, the cumulative tolerance caused by layering on the frame in the traditional process is eliminated, and the concentricity of the voice coil is absolutely guaranteed.

[0060] (2) Achieving standardized and fully automated production of wires: By setting up dedicated wire threading channels on the U-shaped sidewalls, the routing of wires is completely physically constrained. This allows the robotic arm to perform standardized and flat wiring operations in the pre-assembly stage, just like inserting wires, completely solving the problem of difficult wire management in three-dimensional space and greatly improving the degree of automation and production efficiency.

[0061] (3) Enhance customer manufacturing capabilities: After receiving the pre-assembled components, customers (speaker finished product manufacturers) only need to perform one "overall drop into the frame" action and wire bonding to complete the assembly, which greatly reduces the complexity of the customer's process, labor costs and equipment investment.

[0062] (4) The pre-assembled speaker unit structure composed of U-shaped bracket, wire and spring can be bonded by composite process, making it more suitable for mass production, with limited increase in cost.
