Description

Technical Field

[0001] This application relates to the field of loudspeaker technology, and more particularly to a loudspeaker assembly. Background Technology

[0002] In existing loudspeaker technology, loudspeaker diaphragms typically use two main categories of materials: flexible materials, such as silk diaphragms, various synthetic fiber diaphragms, and adhesive materials; and rigid materials, such as aluminum diaphragms, titanium diaphragms, and various polymer diaphragms. Flexible diaphragms, due to their flexibility, can better respond to high-frequency sound waves and exhibit good reproduction capabilities in the high-frequency range, covering a high-frequency range of approximately 40kHz. Rigid diaphragms, through the rigidity of their material, provide a more precise high-frequency response, also achieving high-frequency reproduction up to 40kHz, effectively reproducing high-frequency signals, especially ultra-high-frequency audio signals.

[0003] However, despite these designs improving high-frequency reproduction capabilities, existing technologies still have certain limitations in high-frequency response, especially above 40kHz, where existing speaker components have not been able to fully overcome issues such as high-frequency distortion and unstable response.

[0004] A common problem in existing technologies is that, despite high-frequency optimization designs, the structural design of loudspeaker components still fails to fully reproduce high-frequency signals. During high-frequency reproduction, especially above 40kHz, the diaphragm, voice coil, and magnetic circuit systems of existing loudspeakers have limitations in response speed, transmission accuracy, and frequency range. Specifically, while the materials and structural design of the loudspeaker diaphragm can provide a certain degree of high-frequency response, distortion and insufficient accuracy may still occur in ultra-high-frequency reproduction. Therefore, designing a loudspeaker component that can effectively extend high-frequency response and reduce distortion remains a major challenge for current technology. Summary of the Invention

[0005] The purpose of this invention is to provide a loudspeaker assembly to solve the technical problems of high-frequency distortion and unstable response of existing loudspeaker assemblies mentioned in the background art.

[0015] Furthermore, it also includes an arc-shaped transition structure, which includes a first transition member and a second transition member. The first fitting edge and the convex and concave groove are connected through the first transition member, and the second fitting edge and the inner groove are connected through the second transition member. The outer sides of the first transition member and the second transition member are provided with staggered trapezoidal convex ridges. The inner groove and the convex and concave groove are provided with wedge-shaped locking points corresponding to the trapezoidal convex ridges. The continuous groove group and the arc-shaped transition structure are connected by the interlocking of the trapezoidal convex ridges and the wedge-shaped locking points.

[0016] Furthermore, the frame has several circular through holes on its side, the through holes being located above the gap between the polar plate and the magnetic iron, and a porous adjustment mesh is provided inside the circular through holes, the porous adjustment mesh being composed of multiple layers of interlaced mesh sheets.

[0021] Compared with the prior art, this application has the following beneficial effects:

[0022] This application employs a combination of a diamond diaphragm and a precious metal damping layer, giving the speaker a significant advantage in high-frequency response. It better withstands high-frequency signal vibrations and reduces distortion caused by insufficient diaphragm flexibility. Simultaneously, the folded edge design on the outer edge of the diaphragm further enhances its rigidity, improving its accuracy during high-frequency reproduction. The precious metal damping layer covering the diaphragm surface effectively suppresses the peak value of high-frequency resonances, reducing high-frequency distortion and resulting in clearer and smoother sound quality. The frame and diaphragm are bonded with rigid adhesive, providing more stable structural support and preventing deformation or instability during high-frequency playback, ensuring clear and high-quality audio transmission. In terms of magnetic circuit structure, a layered combination of rare-earth magnets, magnetic iron, copper caps, and polar plates is used, along with a receiving cavity, providing a stronger magnetic field and precise magnetic force distribution, further improving the speaker's frequency response range and sensitivity.

[0023] In summary, the speaker assembly of this application, after the audio electrical signal is input to the voice coil, generates a Lorentz force with the magnetic field in the magnetic circuit structure. This force is transmitted through the carbon fiber voice coil skeleton and extremely rigid adhesive to the diamond diaphragm, driving air vibration to generate sound waves and reproduce the input audio signal. This can extend the high-frequency response of the speaker to 60-70kHz, far exceeding the limitations of existing technologies, greatly improving the high-frequency performance of the speaker, enabling it to reproduce ultra-high frequency audio signals more realistically and clearly, and solving the shortcomings of existing speakers in frequency response and distortion control in the ultra-high frequency range.

[0037] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] In one embodiment, please refer to Figures 1 to 7 A loudspeaker assembly includes a diamond diaphragm 1, the diamond diaphragm 1 comprising a diaphragm body 11 and a precious metal damping layer 12 covering the diaphragm body 11, the outer edge of the diaphragm body 11 being configured as a folded edge 13 at a preset angle; a frame 3, one end of the frame 3 being bonded to the folded edge 13 by rigid adhesive; and a magnetic circuit structure 2, including a rare earth magnet 21, a magnetic permeable iron 22, a copper cap 23, and a polarity plate 24, the magnetic permeable iron 22 having a receiving cavity 25 inside, the rare earth magnet 21... 1. A polarizing plate 24 and a copper cap 23 are stacked in the receiving cavity 25. There is a gap between the inner side of the magnetic iron 22 and the outer side of the polarizing plate 24. The end of the frame 3 away from the diamond diaphragm 1 extends into the gap. The side of the copper cap 23 extends the side of the rare earth magnet 21 and covers the outer periphery of the polarizing plate 24. A voice coil 4 is wound around the side of the frame 3 near the magnetic iron 22 and is located in the gap between the polarizing plate 24 and the magnetic iron 22.

[0039] In this embodiment, a diamond diaphragm 1 with an extremely high Young's modulus (1050 GPa) is provided. This rigidity enables the diamond diaphragm 1 to exhibit stable and accurate vibration characteristics under the drive of high-frequency signals. The outer edge of the diamond diaphragm 1 is designed with a pre-angled folded edge 13 to increase the diaphragm's rigidity, allowing it to maintain better stability and vibration accuracy when responding to high-frequency signals, avoiding the deformation and sound distortion that commonly occur in low-rigidity materials at high frequencies. The surface of the diamond diaphragm 1 is covered with a precious metal damping layer 12, which can be deposited using platinum or gold materials. The precious metal damping layer 12 can effectively suppress high-frequency resonance peaks, avoiding the distortion phenomena commonly found in traditional loudspeakers at high frequencies, especially the harsh high frequencies caused by resonance. The precious metal damping layer 12 can reduce the vibration amplitude of the diaphragm, effectively eliminating excessive reflection caused by the diaphragm material characteristics, making the sound quality clearer and smoother, and significantly improving the detail reproduction capability of the audio. Overall, the combination of the diamond diaphragm 1 and the precious metal damping layer 12 maintains high-frequency response while avoiding harshness in the sound quality, ensuring sound purity. The frame 3 is made of carbon fiber, possessing extremely high rigidity (approximately 430 GPa) and low density, allowing it to provide sufficient support to stabilize the movement of the voice coil 4 and effectively reduce energy loss due to the frame's own weight. One end of the carbon fiber frame 3 is firmly bonded to the folded edge 13 of the diamond diaphragm 1 using rigid adhesive, ensuring a stable and secure connection between the diaphragm and the frame 3. This connection method enhances the rigidity and stability of the entire vibration system, preventing loosening that may occur during vibration and further improving the speaker's high-frequency response accuracy. Another advantage of the frame 3 is its lightweight yet efficient transmission of the voice coil 4's vibration signal, reducing energy loss due to the frame 3's weight and ensuring that the voice coil 4 responds accurately and quickly to the drive signal, thus improving low-frequency performance.

[0040] To further enhance the overall performance of the loudspeaker, the present invention employs a magnetic circuit structure 2 consisting of rare-earth magnets 21, magnetic conductors 22, a copper cap 23, and a polarizing plate 24. The magnetic conductors 22 have an internal cavity 25, within which the rare-earth magnets 21, polarizing plate 24, and copper cap 23 are stacked, optimizing the magnetic field distribution. A gap exists between the inner side of the magnetic conductors 22 and the outer side of the polarizing plate 24. The end of the frame 3 furthest from the diamond diaphragm 1 extends into this gap, ensuring magnetic field stability and allowing the voice coil 4 to vibrate freely within the magnetic field, thus guaranteeing efficient energy conversion. The side of the copper cap 23 extends to the side of the rare-earth magnets 21 and covers the outer periphery of the polarizing plate 24, stabilizing the magnetic field strength and preventing audio distortion caused by magnetic field inhomogeneity, ensuring the loudspeaker maintains efficient operation across different frequency bands. The working principle of this application is that after the audio electrical signal is input into the voice coil 4, it generates Lorentz magnetic force with the magnetic field in the magnetic circuit structure 2. This force is transmitted through the carbon fiber voice coil skeleton 3 and the extremely rigid glue to the diamond diaphragm 1, which drives the air to vibrate and generate sound waves to reproduce the input audio signal.

[0041] Through the synergistic effect of the above designs, the speaker assembly of this invention exhibits significant advantages in multiple aspects, effectively overcoming the limitations of existing speakers in high-frequency response, especially in the high-frequency range above 40kHz. The combination of the diamond diaphragm 1 and the precious metal damping layer 12 greatly expands the high-frequency response range of the speaker, effectively reducing resonance peaks and distortion, resulting in clearer and smoother sound quality. The lightweight and high-rigidity characteristics of the carbon fiber voice coil skeleton 3 ensure efficient transmission of vibration signals, reduce energy loss, and improve the overall efficiency of the speaker. The optimized design of the magnetic circuit system ensures the stability and efficiency of the magnetic field, improving the speaker's performance and sound reproduction capabilities. In summary, the speaker assembly of this invention not only performs excellently in sound quality but also features significant innovations in structural design, meeting the high demands of high-end audio systems for sound quality and performance.

[0042] In summary, the speaker assembly of this application effectively expands the speaker's response capability in the high-frequency range, especially in the frequency range exceeding 40kHz, significantly reduces high-frequency distortion, improves the speaker's sound quality performance, and extends the high-frequency bandwidth that the speaker can reproduce to 60-70kHz, which can meet more demanding audio reproduction requirements and solves the technical bottleneck in ultra-high frequency response in the prior art.

[0043] In another embodiment, the diaphragm body 11 and the noble metal damping layer 12 are connected by a multi-level interlocking and sealing connection. The upper surface of the diaphragm body 11 is processed with a continuous array of trapezoidal grooves, and the inner walls of the grooves are engraved with micro-wave textures. The noble metal damping layer 12 is formed by high-temperature deposition and embedded in the grooves, with inverted conical flanges at its edges, which are interlocked with the top of the grooves of the diaphragm body 11. The outer edge of the diaphragm body 11 is connected to the folded edge 13 by a composite pleated nesting connection. The outer edge of the diaphragm body 11 is designed with a sawtooth-shaped tapered structure. The inner side of the folded edge 13 is provided with an annular pleated layer, which is divided into three gradually changing arc-shaped pleats from the inside out. Each pleat has a spiral support strip embedded in it, which is connected to the serrated outer edge of the diaphragm body 11 by heat fusion. The folded edge 13 is connected to one end of the frame 3 by a multi-hole snap-fit ​​connection. The outer edge of the folded edge 13 is provided with a wavy pleated edge, and the surface of the pleated edge is distributed with a multi-hole protrusion array. Each protrusion has a micro hook-shaped protrusion at the top. One end of the frame 3 is provided with a matching mesh groove structure. The hook-shaped protrusion and the mesh groove are filled and cured together with rigid glue. In this embodiment, the connection strength between the diaphragm body 11 and the precious metal damping layer 12 is enhanced by the multi-stage interlocking and sealing connection method. At the same time, the design of the trapezoidal groove array and micro-wave texture increases the contact area and friction of the connection surface, effectively preventing the damping layer from falling off or shifting, and ensuring the stability and durability of the speaker in long-term use. The nested composite pleats create a tighter and more stable connection between the outer edge of the diaphragm body 11 and the folded edge 13. The serrated, tapering structure combined with the annular pleats enhances the rigidity of the connection, optimizes the diaphragm's vibration characteristics, and further improves the speaker's sound quality. The multi-hole snap-fit ​​connection, through its wavy pleats, multi-hole protrusion array, and micro-hook-like protrusions, achieves an efficient connection between the folded edge 13 and the frame 3. This not only ensures a strong connection but also effectively reduces energy loss during vibration, improving the overall efficiency of the speaker.

[0044] In one embodiment, a fixing bracket 5 is further included. The fixing bracket 5 includes a first part 51 and a second part 52. A first groove 53 is provided at the connection between the first part 51 and the second part 52. The first part 51 is fixedly connected to the upper side of the magnetic iron 22. The inner side of the second part 52 is fixedly connected to the outer side of the magnetic iron 22. A plurality of protrusions 54 are provided at intervals on the outer side of the second part 52.

[0045] In this embodiment, the fixing bracket 5 serves to support and fix the magnet 22, fixing the first part 51 to the upper side of the magnet 22 and the inner side of the second part 52 to the outer side of the magnet 22. This effectively prevents the magnet 22 from shifting or loosening during use, ensuring its continuous and stable operation and avoiding magnetic field fluctuations or unevenness caused by position changes. This, in turn, guarantees the stability and high efficiency of the speaker's audio performance. The first groove 53 between the first part 51 and the second part 52 helps absorb some external vibrations, thereby reducing negative impacts on the speaker assembly. Specifically, the first groove 53 between the first part 51 and the second part 52 forms a cavity with the upper side of the magnet 22. During the reproduction of high-frequency and low-frequency signals, the speaker vibrates, which can affect sound quality and may also adversely affect other parts of the speaker assembly. By creating a cavity with a groove, unnecessary effects caused by vibration can be effectively mitigated and absorbed, preventing vibration from being transmitted to the fixing bracket 5 or other parts of the magnet 22. Especially under high-frequency vibration conditions, the cavity effectively reduces the interference of vibration on the magnet 22, preventing high-frequency distortion or magnetic field instability, thereby improving the audio clarity and accuracy of the speaker. During the speaker's operation, the magnet 22 and other components generate heat, and the space within the cavity provides a buffer and dissipation channel for this heat. Because the cavity has sufficient space, heat can be dispersed over a wider area, preventing excessively high temperatures from concentrating in a localized region, thus improving the heat resistance of the speaker components. Better heat dissipation reduces performance degradation caused by overheating and extends the speaker's lifespan. Several protrusions 54 are spaced apart on the outer side of the second part 52. The protrusions 54 enhance the stability of the outer side of the second part 52, forming an effective vibration absorption and protection structure through their spaced arrangement. When the speaker is operating, the protrusions 54 effectively disperse vibrations and impacts transmitted to the speaker components from the outside, reducing interference with other structural parts, ensuring that the speaker does not experience unnecessary sound quality distortion due to external vibrations when playing high-frequency or low-frequency sounds. Furthermore, the protrusions 54 effectively improve the speaker's heat dissipation performance. When a loudspeaker operates under high load for an extended period, the temperature of its components may rise. The protrusion 54 provides space for heat dissipation, improving the loudspeaker's heat resistance and operational stability, thereby extending the loudspeaker's lifespan.

[0046] In one embodiment, the central part of the protruding post 54 is a hollow cylinder 541, and the inner wall of the cylinder 541 is provided with an internal thread groove. The thread groove is embedded with radially distributed arc-shaped reinforcing ribs. The top of the protruding post 54 is an arc-shaped crown 542. The bottom surface of the arc-shaped crown 542 is provided with an external thread protrusion that matches the internal thread groove. The outer edge of the arc-shaped crown 542 extends into a wavy fold along the arc direction. The arc-shaped crown 542 is connected to the hollow cylinder 541 by a threaded connection.

[0047] In this embodiment, the arc-shaped crown 542 and the hollow cylinder 541 are firmly joined by a threaded connection, effectively preventing loosening or displacement during speaker operation. The radially distributed arc-shaped reinforcing ribs within the internal thread groove increase its strength and rigidity. These ribs, through their radial distribution, effectively disperse the stress generated by the threaded connection, preventing stress concentration in a specific part of the thread groove and reducing the risk of damage or deformation. Furthermore, the arc-shaped reinforcing ribs enhance the load-bearing capacity of the connection, allowing the entire structure to withstand greater loads without easily deforming under external impact or pressure. The engagement of the external threaded ridge with the internal thread groove allows the two components to be easily and firmly connected by rotation, avoiding a complex installation process. The high precision of threaded connections helps ensure a tight connection, reducing the possibility of loosening. The screw-on method also simplifies installation and disassembly. The fit between the external thread ridge and the internal thread groove guarantees connection accuracy, ensuring that each component maintains its predetermined relative position during speaker operation, preventing performance instability or sound distortion caused by component misalignment. The wavy pleats extending along the curvature of the arc-shaped crown 542 not only enhance its aesthetic appearance but also improve its strength, preventing deformation or damage during operation and increasing structural elasticity. This elastic design helps absorb and buffer vibrations generated during high-load operation, reducing vibration transmission to other components and lowering the risk of sound distortion and component damage caused by vibration. The addition of the wavy pleats also effectively improves the speaker's response speed during audio playback, making the speaker more sensitive in high and low frequency responses, resulting in clearer and more accurate sound quality.

[0048] In one embodiment, an elastic connector 6 is further included. The elastic connector 6 includes an end fitting structure and a continuous groove group. The end fitting structure includes a first fitting edge 61 and a second fitting edge 62. The first fitting edge 61 is fixedly connected to the upper side of the fixed bracket 5, and the second fitting edge 62 is attached to the diamond diaphragm 1. The continuous groove group is disposed between the first fitting edge and the second fitting edge 62. The continuous groove group includes an inwardly recessed inner groove 63 and an outwardly protruding convex groove 64.

[0049] In this embodiment, the first mating edge 61 is fixedly connected to the upper side of the fixed bracket 5, ensuring the stable positioning of the elastic connector 6 in the speaker assembly and preventing loosening or displacement of the elastic connector 6 during operation. This stable connection not only enhances the structural stability of the speaker but also ensures that the diaphragm can move stably on the fixed bracket 5, thereby ensuring stable sound output and high-efficiency performance of the speaker during long-term operation. The second mating edge 62 is attached to the diamond diaphragm 1, which can further fix the diaphragm and the frame 3, forming a tight but elastic connection. This allows the diaphragm to vibrate stably under the drive of signals of different frequencies and intensities, avoiding excessive vibration or reverse twisting, improving the sound quality of the speaker, reducing distortion, and enhancing the clarity and expressiveness of the audio. The alternating arrangement of the inner groove 63 and the convex groove 64 provides stress buffering effect for the elastic material, enabling the connector to maintain a high elastic recovery capability when subjected to external vibration and impact. The advantage of this design lies in the fact that when the speaker is operating, vibrations are transmitted through the elastic connector 6, and the presence of the grooves effectively mitigates these vibrations, reducing their impact on the diaphragm and mounting bracket 5, and preventing sound quality degradation or distortion caused by vibration. Furthermore, the reverse fit between the inner groove 63 and the convex groove 64 also disperses stress to a certain extent, reducing localized stress concentration and thus extending the lifespan of the speaker assembly. The design of the inner groove 63 and the convex groove 64 also provides a more uniform elastic distribution when the connector is under stress, avoiding the stress concentration problem common in traditional designs. This uniform stress distribution not only ensures the stability of the elastic connector 6 but also improves the overall structural durability. During long-term use, the continuous groove design helps reduce fatigue damage caused by frequent vibrations, ensuring that the speaker assembly can withstand high-intensity use for a longer period, and preventing loose connections or component damage due to material fatigue.

[0050] In one embodiment, an arc-shaped transition structure is further included, comprising a first transition member 71 and a second transition member 72. The first mating edge 61 and the convex and concave groove 64 are connected by the first transition member 71, and the second mating edge 62 and the inner groove 63 are connected by the second transition member 72. The outer sides of the first transition member 71 and the second transition member 72 are provided with staggered trapezoidal convex ridges, and the inner groove 63 and the convex and concave groove 64 are provided with wedge-shaped locking points corresponding to the trapezoidal convex ridges. The continuous groove group and the arc-shaped transition structure are connected by the interlocking engagement of the trapezoidal convex ridges and the wedge-shaped locking points.

[0051] In this embodiment, the connection between the first transition member 71, the first mating edge 61, and the protrusion and groove 64 provides an effective transmission path. The transition function of the first transition member 71 ensures a stable connection between the diaphragm and the fixed support 5. During speaker operation, the diaphragm needs to vibrate precisely on the fixed support 5, and the stability of this vibration has a crucial impact on sound quality. The first transition member 71 ensures the fixation of the mating edge and also ensures a good fit with the protrusion and groove 64, avoiding vibration instability caused by a loose connection, thereby improving the speaker's sound quality performance. The connection between the second transition member 72, the second mating edge 62, and the inner groove 63 is similar to that of the first transition member 71. As part of the curved portion, the inner groove 63, through the connection of the second transition member 72, ensures precise contact between the inner groove 63 and the second mating edge 62, and maintains stability during vibration. This design effectively controls the deformation of the inner groove 63, avoiding sound quality degradation or distortion caused by structural instability due to vibration. The second transition piece 72 not only provides the necessary structural support but also grants the diaphragm the necessary degrees of freedom, enabling it to vibrate efficiently under the influence of the drive signal and ensuring high-fidelity sound output. In the outer design of the arc-shaped transition structure, staggered trapezoidal ridges enhance the stability and robustness of the connection. The trapezoidal ridges, in conjunction with wedge-shaped locking points, ensure a tighter and more reliable connection between the various parts. When the arc-shaped transition structure and the continuous groove assembly are connected through the interlocking of the trapezoidal ridges and wedge-shaped locking points, the structural stability of the entire speaker assembly is improved. The staggered design of the trapezoidal ridges increases the contact area of ​​the connection, making the connection tighter and preventing loosening or detachment due to vibration. This ensures that the speaker maintains reliability for a longer period even under high-intensity vibration.

[0052] In one embodiment, the frame 3 has a plurality of circular through holes 31 on its side. The through holes are located above the gap between the polar plate 24 and the magnetic iron 22. The circular through holes 31 are provided with a porous adjustment mesh, which is composed of multiple layers of interlaced mesh sheets.

[0053] In this embodiment, the circular through-holes 31 on the sides of the frame 3 act as air channels, allowing air to flow inside the speaker assembly, especially above the gap between the polarizer 24 and the magnet 22. During speaker operation, the rapid vibration of the diaphragm causes airflow and pressure fluctuations. By providing these circular through-holes 31, air can flow freely inside the speaker, effectively mitigating the negative effects caused by uneven airflow pressure. The regulating mesh consists of multiple layers of interlaced mesh. This interlaced design improves the uniformity of airflow and better regulates the speed and distribution of airflow. Since the working principle of the speaker assembly involves the generation and propagation of sound waves, any uneven airflow can lead to audio output distortion. The multiple layers of interlaced mesh change the direction and speed of airflow, allowing air to be distributed more evenly as it passes through these meshes, thus avoiding sound quality degradation caused by unstable airflow. High-frequency and low-frequency sound outputs are particularly affected by uneven airflow; the regulating mesh design effectively avoids this problem and improves the speaker's sound quality performance. The porous regulating mesh, composed of multiple layers of interlaced mesh, enhances its overall rigidity, making it less prone to deformation when subjected to changes in internal air pressure, thus ensuring stable airflow. As air passes through these meshes, it is filtered and diverted layer by layer by the interlaced meshes, effectively preventing system instability or noise interference caused by sudden airflow changes. This multi-layered design allows the speaker to maintain a relatively stable operating state, further improving sound fidelity and stability.

[0054] In one embodiment, the outer side of the porous adjustment mesh is provided with a tapered retaining edge, the outer surface of the tapered retaining edge is provided with anti-slip texture, and the inner side of the circular through hole 31 is provided with a tapered hole corresponding to the tapered retaining edge. The porous adjustment mesh and the circular through hole 31 are connected by the interlocking and embedding of the tapered retaining edge and the tapered hole.

[0055] In this embodiment, the tapered locking ridges achieve a secure connection between the porous adjustment mesh and the circular through-hole 31, enhancing installation convenience. The anti-slip texture prevents the tapered locking ridges from easily slipping during installation, thus ensuring the structural stability and durability of the speaker assembly. The interlocking engagement of the tapered locking ridges and the tapered holes allows the porous adjustment mesh to fit tightly within the circular through-hole 31, effectively preventing air leakage and further improving the speaker assembly's operating efficiency. Furthermore, this design facilitates subsequent maintenance and replacement. When the porous adjustment mesh needs cleaning or replacement due to prolonged use, the user can easily remove it from the circular through-hole 31 without disassembling the entire speaker assembly, thereby reducing maintenance costs and time. In summary, the interlocking design of the tapered locking ridges and the tapered holes provides strong support for improving the performance and ease of use of the speaker assembly.

[0056] In one embodiment, a protective cover 8 is further included, which is disposed above the diamond diaphragm 1. The protective cover 8 includes a first circular ring 81, a second circular ring 82 disposed inside the first circular ring 81, and a plurality of arc-shaped connectors 83 connecting the first circular ring 81 and the second circular ring 82. The first circular ring 81 includes an annular base 811 and an arc-shaped surface 812. The arc-shaped surface 812 is fixedly connected to the elastic connector 6. The annular base 811 is disposed around the outer side of the fixed bracket 5. A spiral-shaped track is provided on the inner side of the first circular ring 81. An arc-shaped ridge is provided on one end of the arc-shaped connector 83 near the first circular ring 81. The first circular ring 81 and the arc-shaped connector 83 are connected by compression fitting through the spiral-shaped track and the arc-shaped ridge. A dustproof mesh is provided between every two arc-shaped connectors 83.

[0057] In this embodiment, the first circular ring 81 serves as the main structural component of the protective cover 8. Its annular base 811 surrounds the outer side of the fixed bracket 5 and includes an arc-shaped surface 812 fixedly connected to the elastic connector 6. This design allows the protective cover 8 to be firmly fixed to other components of the speaker, preventing it from loosening or shifting during speaker operation and enhancing the structural stability of the speaker assembly. The fixed connection between the arc-shaped surface 812 of the first circular ring 81 and the elastic connector 6 further improves the connectivity between the protective cover 8 and other components, ensuring that the protective cover 8 will not be excessively deformed or damaged under vibration or external force. A spiral-shaped insert is designed inside the first circular ring 81. This spiral-shaped insert allows the various annular components to fit tightly, preventing components from loosening due to long-term use or external vibration. Through this design, the overall structure of the protective cover 8 not only has good robustness but also maintains high convenience during installation and disassembly. Multiple arc-shaped connectors 83 are connected to the first circular ring 81. Each arc-shaped connector 83 has an arc-shaped protrusion at one end. These protrusions cooperate with a spiral-shaped guide rail, which can firmly connect the arc-shaped connector 83 to the first circular ring 81 through compression fitting. The arc-shaped connector 83 is designed with good elasticity and durability. While ensuring connection strength, it can also adapt to the vibration and deformation of the speaker during operation, avoiding excessive wear or loosening. Through the cooperation of the spiral-shaped guide rail and the arc-shaped protrusion, a stable and reliable connection structure is formed between the arc-shaped connector 83 and the first circular ring 81. This connection method not only improves the overall strength of the protective cover 8, but also enhances the stability of the speaker during long-term use. A dustproof mesh is set between every two arc-shaped connectors 83. The main function of the dustproof mesh is to prevent external dust or impurities from entering the speaker, especially in the diaphragm area covered by the protective cover 8. The entry of dust or impurities may not only cause physical damage to the diaphragm, but may also affect the sound quality of the speaker. By installing a dust filter, dust can be effectively prevented from entering, thus protecting the speaker's internal structure and sound quality stability. This design effectively extends the speaker's lifespan while reducing maintenance frequency and improving the user experience.

[0058] In one embodiment, a second groove 251 and a third groove 252 are provided on the inner bottom of the magnetic iron 22. The depth of the second groove 251 is greater than the depth of the third groove 252. The second groove 251 is the bottom of the receiving cavity 25. The third groove 252 is provided on the outer side of the second groove 251. The third groove 252 forms part of the gap between the upper inner side of the magnetic iron 22 and the third groove 252. A heat dissipation fin is provided on the bottom of the second groove 251. The heat dissipation fin is evenly distributed circumferentially along the bottom of the second groove 251.

[0059] In this embodiment, a second groove 251 and a third groove 252 are provided on the inner bottom of the magnet 22, with the second groove 251 being deeper than the third groove 252. The second groove 251 is located at the bottom of the receiving cavity 25, while the third groove 252 is located on the outer side of the second groove 251. This design makes the internal structure of the magnet 22 more compact and provides better physical support and functional separation for the speaker. The difference in layout and depth of the two grooves determines their relationship, allowing the entire assembly to balance strength and heat dissipation in its structure. Heat dissipation fins are installed at the bottom of the second groove 251, and the fins are evenly distributed circumferentially along the bottom of the second groove 251, thereby effectively improving the heat dissipation efficiency of the speaker assembly. The heat dissipation fins enhance heat dissipation capacity through their increased surface area, helping to release the heat generated by the speaker during operation in a timely manner, thus avoiding overheating. The accumulation of heat can not only affect the performance of the speaker, but may even lead to damage to components or a shortened service life. Therefore, through this structural design, heat dissipation performance is significantly improved, ensuring that the speaker can operate stably under high load or long-term operation. A gap is formed between the third groove 252 and the upper inner side of the magnet 22. This gap enhances airflow within the speaker, improving heat exchange and airflow distribution, thus further optimizing heat dissipation. The size of this gap, and its interaction with the third groove 252, provides sufficient space for the speaker's structure, allowing the heat sink fins to function effectively while avoiding poor heat dissipation caused by excessive sealing or overly compact designs. By precisely controlling the distribution of the heat sink fins and the size of the gap, heat generated by the speaker under high load can be effectively prevented from accumulating in a localized area, ensuring stable sound output even under prolonged high-power operation. The combination of the gap and the third groove 252 also provides a smoother flow path for heat within the speaker, optimizing the overall system's heat dissipation efficiency.
