Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a basket frame structure that enhances mechanical impact. Background Technology

[0002] As a core component for electroacoustic conversion, the structural reliability of loudspeakers directly affects the performance of audio equipment. In traditional loudspeaker structures, the outer frame structure used to fix the magnet is called a basket structure. Because the basket and magnet are in direct surface-to-surface contact, impact forces cannot be effectively dispersed during use, posing a risk of magnet detachment. In existing technologies, the contact surface between the basket and magnet is usually designed as a flat surface, which leads to stress concentration under mechanical impact, easily causing adhesive failure. Furthermore, the design of the glue reservoir in the basket is often unreasonable, resulting in insufficient buffering of the glue between the basket and magnet, uneven glue layer thickness, and instances of magnet detachment during testing or use. These structural defects not only affect the lifespan of the loudspeaker but also lead to sound quality degradation. Especially under high-frequency vibration environments, traditional basket structures struggle to maintain stable mechanical connection performance, severely restricting the improvement of loudspeaker product reliability. Utility Model Content

[0007] In some embodiments, the groove depth is 0.1mm-5mm.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the basket adopts a wave-shaped structure design, which is to avoid considering only a single force transmission path and reduce deformation and damage during mechanical impact; the basket and the magnet cover have a relatively wide area at the glued joint, which can store more glue, increase the thickness and volume of the glue, and effectively absorb and buffer the impact force during mechanical impact, reduce the risk of magnet detachment and failure of the speaker during drop tests, drum tests and consumer use, avoid permanent damage to the speaker, and improve customer satisfaction.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In existing technologies, the contact surface between the speaker frame and the magnet in a loudspeaker structure is designed as a flat surface, which prevents the effective dispersion of mechanical impact forces. When the device is subjected to external vibration or impact, stress concentrates in a localized area of ​​the contact surface, easily causing adhesive failure between the magnet and the frame. Traditional glue reservoir designs do not consider the flow characteristics of the glue, resulting in uneven glue distribution under dynamic loads, further exacerbating the risk of adhesive interface separation. For example, in car audio systems, the continuous vibration generated by vehicle movement can cause micro-cracks at the joint surface between the magnet and the frame, ultimately leading to the failure of acoustic components.

[0018] To address these issues, the primary causes of magnetic shield detachment must first be analyzed: stress concentration from planar contact and uneven distribution of the adhesive buffer layer. Research into the vibration transmission path revealed that stress dispersion relies on optimizing the geometry of the contact surface. Further observation of the adhesive flow characteristics under dynamic load showed that traditional adhesive reservoirs cannot maintain adhesive layer continuity during impact. The final solution is to construct a wave-shaped structure with adhesive storage function on the contact surface, using grooves of a specific shape to simultaneously achieve stress dispersion and adhesive positioning.

[0019] Therefore, as Figure 1-5 As shown, this application proposes a basin frame structure to enhance mechanical impact, including a basin frame body. The inner side of the basin frame body is provided with a wave groove structure consisting of a plurality of continuously and uniformly arranged grooves on the surface in contact with the magnetic cover. Each groove is configured as a structure with a closed bottom and an open top. The contact surface of the magnetic cover and the groove form a glue storage tank, which is filled with adhesive.

[0020] The speaker frame body refers to the annular metal or plastic frame supporting the speaker's magnetic circuit system, which can be manufactured using aluminum alloy die-casting and serves as the mounting base for the magnetic cover. The wave-groove structure refers to a regular array of grooves extending circumferentially along the contact surface, which can be achieved using CNC milling, altering the stress transmission path through periodic undulations. The bottom-closed, top-open structure means the bottom of the groove is integrally connected to the speaker frame body, which can be achieved by controlling the machining depth, creating a glue storage space while preventing glue leakage. The groove depth is set in the range of 0.1mm-5mm, which can be achieved using stepped machining tools; this size range balances structural strength and glue storage capacity.

[0021] Specifically, the wave-groove structure creates alternating raised support areas and recessed adhesive storage areas between the frame and the magnetic cover. When mechanical impact is applied to the magnetic cover, the raised sections decompose the concentrated stress into components in multiple directions, while the adhesive layer in the recessed areas absorbs the remaining energy. The closed bottom structure ensures that the adhesive storage area forms an independent sealed cavity, preventing adhesive loss before curing. The open top structure allows the adhesive to fully fill the grooves during assembly, forming a mechanically interlocking structure after curing. In a vibration environment, the wave-shaped contour guides stress along the crests and troughs of the grooves, preventing excessive stress accumulation in a single direction.

[0022] Compared to existing technologies, traditional planar contact structures rely solely on the adhesive film to withstand shear forces, while the corrugated groove structure achieves a triple protection mechanism through geometric modification: the groove crests provide rigid support points, the troughs form an elastic buffer layer for storing adhesive, and the mechanical interlocking effect generated after the adhesive cures enhances the bonding strength. This combined effect allows the bonding surface to maintain structural integrity even when subjected to multi-directional impacts.

[0023] Through the above technical solution, this application effectively disperses the concentrated stress generated by mechanical impact, significantly improving the bonding stability between the magnet and the frame. The adhesive storage space formed by the wave-shaped grooves ensures uniform distribution and full penetration of the adhesive, maintaining the continuity of the adhesive layer under dynamic loads. The closed bottom structure prevents adhesive loss and bonding failure, while the open top design ensures efficient adhesive filling. This structure is particularly suitable for speaker assemblies in high-vibration environments, fundamentally solving the industry problem of magnet detachment.

[0024] This application further proposes that the cross-section of the upper opening of the groove is set in the shape of a flared mouth.

[0025] The flared opening refers to an opening whose cross-sectional shape gradually expands from the inside out. This can be achieved using a trapezoidal, arc-shaped, or conical structure, with the width of the opening gradually increasing from the bottom to the top. This structure increases the contact area of ​​the adhesive at the edge of the groove by expanding the opening cross-section, making it easier for the adhesive to fill the gap between the inner wall of the groove and the magnetic cover, thereby improving the fluidity and uniformity of the adhesive distribution.

[0026] Specifically, the flared shape of the groove opening forms a flow channel during the bonding process between the magnetic cover and the frame. Under gravity or pressure, the adhesive flows naturally into the groove along the sloping surface of the flared opening, preventing adhesive buildup or insufficient filling due to a narrow opening. After the adhesive cures, a continuous and gradually varying thickness buffer layer is formed within the groove. Its cross-sectional shape matches the flared opening, allowing impact force to be dispersed and transmitted along the sloping surface of the adhesive layer, reducing localized stress concentration. Furthermore, the flared structure at the edge of the flared opening limits adhesive overflow, ensuring a clean bonding surface.

[0027] Compared to existing technologies, traditional adhesive storage tanks typically have vertical openings or rectangular cross-sections. During filling, surface tension can easily create voids, and the adhesive layer thickness at the edges is uneven, leading to decreased bond strength. This application utilizes a flared opening design, allowing the adhesive to spread evenly along the slope during flow. This improves filling efficiency while reducing air bubbles and delamination defects, and enhances the adhesive layer's ability to absorb impact energy.

[0028] Through the above technical solution, this application solves the problem of uneven glue distribution caused by unreasonable opening shape of traditional basin rack glue storage tank, effectively improves the bonding strength between glue and magnetic cover and basin rack, and avoids glue layer cracking or magnetic cover falling off under mechanical impact.

[0029] This application further proposes that the height between the closed end of the bottom of the groove and the upper opening is less than or equal to the height of the surfaces where the magnetic cover and the basin stand are bonded.

[0030] The height between the closed end of the groove and the upper opening refers to the vertical distance from the lowest point of the groove to the opening. This can be achieved by adjusting the molding depth of the mold. Its function is to match the height of the adhesive filling space with the bonding surface, ensuring a uniform adhesive layer thickness. The bonding surface between the magnetic cover and the basin frame refers to the planar area where the two come into contact through adhesive. This can be achieved using a flat annular contact surface. Its function is to limit the distribution range of the adhesive layer, preventing adhesive overflow or insufficient filling.

[0031] Specifically, when the height of the groove matches the height of the bonding surface, the filling layer formed by the adhesive within the groove can completely cover the bonding surface, without excessive adhesive buildup due to an overly deep groove or insufficient adhesive layer thickness due to an overly shallow groove. Under mechanical impact, the evenly distributed adhesive layer effectively disperses stress, preventing localized stress concentration that could lead to delamination.

[0032] This solution improves bonding reliability by matching the height of the groove with the height of the bonding surface, allowing the adhesive to form a continuous and stable buffer layer within the groove.

[0033] Through the above technical solution, this application solves the problem of magnetic cover easy to fall off due to uneven adhesive layer thickness in traditional basin frames. The adhesive forms a uniformly distributed buffer structure in the groove, which enhances the impact resistance of the bonding surface and avoids the risk of adhesive waste or bonding failure.

[0034] This application further proposes a groove depth of 0.1mm-5mm.

[0035] The groove depth refers to the vertical distance from the closed end of the groove to the upper opening. It can be achieved through machining or mold forming processes. This depth range is set to ensure that the glue fills the space while avoiding excessive weakening of the basin frame structure.

[0036] Specifically, the lower limit of the groove depth is controlled at 0.1mm to prevent insufficient adhesive storage leading to inadequate adhesive layer thickness; the upper limit is limited to 5mm to avoid a decrease in the local structural strength of the basin frame due to excessively deep grooves. When the magnetic cover is bonded to the basin frame, the adhesive seeps into the groove through capillary action. Grooves within this depth range can both create sufficient adhesive storage space to absorb mechanical impact energy and maintain the overall structural stability of the basin frame.

[0037] Compared to existing technologies, the depth of traditional glue reservoirs in plastic basins is not quantitatively designed, resulting in uneven glue distribution and ineffective shock absorption. This solution, by limiting the depth range of the groove, creates a controllable buffer space in the vertical direction of the glue reservoir, thereby optimizing the glue distribution and stress dispersion path.

[0038] Through the above technical solution, this application solves the problem of glue buffer failure caused by unreasonable glue storage tank depth in traditional basin frames. Under the premise of ensuring the structural integrity of the basin frame, the glue layer can effectively absorb mechanical impact energy, significantly reducing the risk of magnetic cover falling off under dynamic load.
