Abstract
Description
Technical Field
[0001] The present application relates to the technical field of loudspeakers, and in particular to a loudspeaker assembly. Background Art
[0002] In existing speaker technology, speaker diaphragms are typically made of two main types of materials: flexible materials, such as silk membranes, various chemical fiber membranes, and rubber-coated materials; and rigid materials, such as aluminum membranes, titanium membranes, and various polymer membranes. Flexible diaphragms, due to their flexibility, are better able to respond to high-frequency sound waves and exhibit excellent reproduction capabilities in the high-frequency range, covering high frequencies up to approximately 40kHz. Rigid diaphragms, on the other hand, utilize their material rigidity to provide a more precise high-frequency response, similarly enabling high-frequency reproduction up to 40kHz, effectively reproducing high-frequency signals, especially ultra-high-frequency audio signals.
[0003] However, although these designs have improved the high-frequency reproduction capability, the existing technology still has certain limitations in high-frequency response. In particular, when the frequency exceeds 40kHz, the existing speaker components fail to fully overcome problems such as high-frequency distortion and response instability.
[0004] A common problem in the prior art is that, despite the adoption of high-frequency optimization design, the structural design of the speaker assembly still fails to fully achieve adequate reproduction of high-frequency signals. During the reproduction of high-frequency bands, especially frequencies above 40kHz, the diaphragm, voice coil and magnetic circuit system of existing speakers have certain limitations in response speed, transmission accuracy and frequency range. Specifically, although the material and structural design of the speaker diaphragm can provide a certain degree of high-frequency response, distortion and insufficient accuracy may still occur during the reproduction of ultra-high-frequency bands. Therefore, how to design a speaker assembly that can effectively extend the high-frequency response and reduce distortion remains the main challenge facing current technology.

[0024] The technical solution of the present application will be further explained below with reference to the accompanying drawings and through specific implementation methods.
[0025] In one embodiment, see Figures 1 to 7A speaker assembly includes a diamond diaphragm 1, wherein the diamond diaphragm 1 includes a diaphragm body 11 and a precious metal damping layer 12 covering the diaphragm body 11, wherein the outer edge of the diaphragm body 11 is set as a folding edge 13 with a preset angle; a skeleton 3, wherein one end of the skeleton 3 is bonded to the folding edge 13 by rigid glue; a magnetic circuit structure 2, including a rare earth magnet 21, a magnetic conductive iron 22, a copper cap 23 and a polarity piece 24, wherein the magnetic conductive iron 22 is provided with a receiving cavity 25, and the rare earth magnet 2 1. The polarity piece 24 and the copper cap 23 are stacked in the accommodating cavity 25. There is a gap between the inner side of the magnetic iron 22 and the outer side of the polarity piece 24. The end of the skeleton 3 away from the diamond diaphragm 1 extends into the gap. The side of the copper cap 23 extends along the side of the rare earth magnet 21 and covers the outer periphery of the polarity piece 24. The voice coil 4 is wound around the side of the skeleton 3 close to the magnetic iron 22 and is located in the gap between the polarity piece 24 and the magnetic iron 22.
[0026] In this embodiment, a diamond diaphragm 1 is provided, featuring an extremely high Young's modulus (1050 GPa). This rigidity enables the diamond diaphragm 1 to exhibit stable and accurate vibration characteristics when driven by high-frequency signals. A pre-set angled fold 13 on the outer edge of the diamond diaphragm 1 increases the diaphragm's rigidity, enabling it to maintain greater stability and vibration accuracy when responding to high-frequency signals, avoiding the deformation and sound quality distortion that commonly occurs with low-rigidity materials in the high-frequency range. The surface of the diamond diaphragm 1 is coated with a precious metal damping layer 12, which can be vapor-deposited from platinum or gold. This precious metal damping layer 12 effectively suppresses high-frequency resonance peaks, avoiding the distortion common in traditional speakers at high frequencies, particularly the harsh high notes caused by resonance. This precious metal damping layer 12 reduces the diaphragm's vibration amplitude, effectively eliminating excessive reflections caused by the diaphragm's material properties, resulting in clearer, softer sound quality and significantly improving the ability to reproduce audio detail. Overall, the combination of the diamond diaphragm 1 and the precious metal damping layer 12 maintains high-frequency response while avoiding harshness and ensuring pure sound. The skeleton 3 is constructed of carbon fiber, boasting extremely high rigidity (approximately 430 GPa) and low density. This allows the skeleton 3 to provide sufficient support to stabilize the movement of the voice coil 4, effectively reducing energy loss due to the skeleton 3's own weight. One end of the carbon fiber skeleton 3 is securely bonded to the folded edge 13 of the diamond diaphragm 1 with rigid glue, ensuring a stable and secure connection between the diaphragm and the skeleton 3. This connection enhances the rigidity and stability of the entire vibration system, preventing potential loosening during vibration and further improving the speaker's high-frequency response. Another advantage of the skeleton 3 is that, while lightweight, it efficiently transmits the vibration signal of the voice coil 4, reducing energy loss due to the skeleton 3's weight and ensuring that the voice coil 4 accurately and quickly responds to the drive signal, enhancing low-frequency performance.
[0027] To further enhance the overall performance of the loudspeaker, the magnetic circuit structure 2 of the present invention comprises a rare earth magnet 21, a magnetic iron 22, a copper cap 23, and a polar plate 24. The magnetic iron 22 is provided with a housing 25, and the rare earth magnet 21, the polar plate 24, and the copper cap 23 are stacked in the housing 25, thereby optimizing the distribution of the magnetic field. A gap exists between the inner side of the magnetic iron 22 and the outer side of the polar plate 24. The end of the skeleton 3 away from the diamond diaphragm 1 extends into the gap, ensuring the stability of the magnetic field and allowing the voice coil 4 to vibrate freely in the magnetic field, thereby ensuring efficient energy conversion. The side edges of the copper cap 23 extend to the side edges of the rare earth magnet 21 and wrap around the outer periphery of the polar plate 24, stabilizing the strength of the magnetic field, avoiding audio distortion caused by an uneven magnetic field, and ensuring that the loudspeaker can maintain efficient operation at 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, which is transmitted to the diamond diaphragm 1 through the carbon fiber voice coil frame 3 and extremely high rigidity glue to promote air vibration to generate sound waves and reproduce the input audio signal.
[0028] Through the mutual cooperation of the above designs, the speaker assembly of the present invention shows significant advantages in many aspects, and effectively overcomes the limitations of the speakers in the prior art in high-frequency response, especially in the high-frequency band 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 reduces the resonance peak and distortion, and makes the sound quality clearer and softer; the light weight and high rigidity of the carbon fiber voice coil frame 3 ensure the efficient transmission of the vibration signal, reduce energy loss, and improve the overall efficiency of the speaker; and the optimized design of the magnetic circuit system ensures the stability and efficiency of the magnetic field, and improves the working performance and sound reproduction ability of the speaker. Overall, the speaker assembly of the present invention not only performs well in sound quality, but also makes significant innovations in structural design, meeting the high requirements of high-end audio systems for sound quality and performance.
[0029] To sum up, the speaker assembly of the present application effectively expands the response capability of the speaker in the high frequency band, especially the frequency range above 40kHz, greatly reduces high-frequency distortion, improves the sound quality performance of the speaker, and extends the high-frequency bandwidth that the speaker can reproduce to 60-70kHz, which can meet more demanding audio playback requirements and solve the technical bottleneck in ultra-high frequency response in the existing technology.
[0030] In another embodiment, the diaphragm body 11 and the precious metal damping layer 12 are connected in a multi-stage interlocking and sealing manner, wherein the upper surface of the diaphragm body 11 is processed with a continuous trapezoidal groove array, and the inner wall of the groove is engraved with a micro-corrugated texture. The precious metal damping layer 12 is formed by high-temperature deposition and embedded in the groove, and its edge is provided with an inverted cone flange, which is connected to the top of the groove of the diaphragm body 11 by bite-engaging; the outer edge of the diaphragm body 11 is connected to the folded edge 13 in a composite pleated nested connection manner, wherein the outer edge of the diaphragm body 11 is designed as a serrated tapered structure , the inner side of the folded edge 13 is provided with an annular pleat, which is divided into three sections of gradually changing arc-shaped pleats from the inside to the outside, and each section of the pleat is embedded with a spiral support bar, which is connected to the serrated outer edge of the diaphragm body 11 by hot-melt bonding; the folded edge 13 is connected to one end of the skeleton 3 by a porous snap-on bonding connection, wherein the outer edge of the folded edge 13 is provided with a wavy pleat, and the surface of the pleat is distributed with a porous convex array, and each convex top has a micro hook-shaped protrusion, and one end of the skeleton 3 is provided with a mesh groove structure matching it, and the hook-shaped protrusion is connected to the mesh groove by filling and curing with rigid glue. In this embodiment, the connection strength between the diaphragm body 11 and the precious metal damping layer 12 is enhanced by a multi-stage interlocking and sealing connection method, and the design of the trapezoidal groove array and the micro-corrugated texture is used to increase 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 combination of the serrated tapered structure and the annular pleats enhances the rigidity of the connection, optimizes the vibration characteristics of the diaphragm, and further improves the speaker's sound quality. The multi-hole snap-on adhesive connection, through the design of the wavy pleats, a multi-hole bump array, and micro-hook-shaped protrusions, achieves an efficient connection between the folded edge 13 and the frame 3. This not only ensures a secure connection but also effectively reduces energy loss during vibration, improving the overall efficiency of the speaker.
[0031] In one embodiment, a fixing bracket 5 is further included, and 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, and 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.
[0032] In this embodiment, the fixing bracket 5 plays the role of supporting and fixing the magnetic iron 22. The first part 51 is fixedly connected to the upper side of the magnetic iron 22, and the inner side of the second part 52 is fixedly connected to the outer side of the magnetic iron 22. This can effectively prevent the magnetic iron 22 from being displaced or loosened during use, allowing the magnetic iron 22 to operate continuously and stably, avoiding magnetic field fluctuations or unevenness caused by position changes, and thus ensuring the stability and high efficiency of the audio performance of the speaker. The first groove 53 provided between the first part 51 and the second part 52 helps absorb some external vibrations, thereby reducing the negative impact on the speaker assembly. Specifically, the first groove 53 provided between the first part 51 and the second part 52 forms a cavity with the upper side of the magnetic iron 22. During the playback of high-frequency and low-frequency signals, the speaker will vibrate. These vibrations will affect the sound quality and may also have adverse effects on other parts of the speaker assembly. By providing a groove to form a cavity, it is possible to effectively mitigate and absorb unnecessary effects caused by vibration, and prevent vibration from being transmitted to the fixing bracket 5 or other parts of the magnetic iron 22. Especially in the case of high-frequency vibration, the cavity can effectively reduce the interference of vibration on the magnetic iron 22, preventing high-frequency distortion or magnetic field instability, thereby improving the audio clarity and accuracy of the speaker. During the operation of the speaker, the magnetic iron 22 and other components generate a certain amount of heat. The space within the cavity provides a buffer and heat dissipation channel. Because the cavity has a certain amount of space, the heat can be dispersed over a wider area, avoiding excessively high temperatures from being concentrated in a local area, thereby improving the heat resistance of the speaker assembly. Better heat dissipation can reduce the performance degradation of the speaker caused by overheating and extend its service life. Several protrusions 54 are arranged at intervals on the outside of the second part 52. The arrangement of the protrusions 54 enhances the stability of the outside of the second part 52. Through their spaced arrangement, an effective vibration absorption and protection structure is formed. When the speaker is operating, the protrusions 54 can effectively disperse the vibrations and impacts transmitted to the speaker assembly from the outside, reducing interference with other structural parts, so that the speaker will not produce unnecessary sound quality distortion due to external vibrations when playing high-frequency or low-frequency sound effects. In addition, the protrusions 54 can also effectively improve the heat dissipation performance of the speaker. When the speaker operates under high load for a long time, the temperature of the components may increase. The protruding column 54 can provide a certain space for the release of heat, thereby improving the heat resistance and working stability of the speaker, thereby extending the service life of the speaker.
[0033] In one embodiment, the middle portion of the boss 54 is a hollow cylinder 541, the inner wall of the cylinder 541 is provided with an internal thread groove, and radially distributed arc-shaped reinforcing ribs are embedded in the thread groove. The top of the boss 54 is an arc-shaped crown 542, and the bottom surface of the arc-shaped crown 542 is provided with an external thread ridge that matches the internal thread groove. The outer edge of the arc-shaped crown 542 extends a wavy frill along the arc direction, and the arc-shaped crown 542 is connected to the hollow cylinder 541 by a threaded connection.
[0034] In this embodiment, the arc-shaped crown 542 and the hollow cylinder 541 can be firmly combined by screwing together, which can effectively prevent loosening or displacement during the operation of the speaker. The radially distributed arc-shaped reinforcement ribs provided in the internal thread groove increase the strength and rigidity of the internal thread groove. These arc-shaped reinforcement ribs can effectively disperse the stress generated by the threaded connection through their radial distribution, avoid stress concentration in a certain part of the thread groove, and thus reduce the risk of damage or deformation of the thread groove. In addition, the design of the arc-shaped reinforcement ribs improves the bearing capacity of the connection part, so that the entire structure can withstand a large load without being easily deformed when subjected to external impact or pressure. The cooperation between the external thread ridge and the internal thread groove enables the two components to be easily and firmly connected together through a rotation operation, avoiding a complicated installation process. The high precision of the threaded connection helps ensure a tight connection, reducing the possibility of loosening. The screw-on connection also simplifies installation and disassembly. The fit between the external thread ridges and the internal thread grooves ensures precise connection, allowing the various components to precisely maintain their predetermined relative positions during operation, avoiding unstable performance or sound quality distortion caused by component misalignment. The wavy frills extending along the outer edge of the curved crown 542 not only provide an aesthetically pleasing appearance, but also enhance the crown's strength, preventing deformation or damage during operation and increasing the structural elasticity to a certain extent. This elastic design helps absorb and cushion vibrations generated during high-load operation, reducing the transmission of vibration to other components and thus reducing the risk of vibration-induced sound distortion and component damage. The addition of the wavy frills also effectively improves the speaker's response speed during audio playback, making the speaker more sensitive in both high and low frequency response and providing clearer and more precise sound quality.
[0035] In one embodiment, an elastic connector 6 is further included, and the elastic connector 6 includes an end interlocking structure and a continuous groove group. The end interlocking structure includes a first interlocking edge 61 and a second interlocking edge 62. The first interlocking edge 61 is fixedly connected to the upper side of the fixed bracket 5, and the second interlocking edge 62 is fitted with the diamond diaphragm 1. The continuous groove group is arranged between the first interlocking edge and the second interlocking edge 62, and the continuous groove group includes an inwardly concave inner groove 63 and an outwardly protruding convex groove 64.
[0036] In this embodiment, the first interlocking edge 61 is fixedly connected to the upper side of the fixed bracket 5 to ensure the firm positioning of the elastic connector 6 in the speaker assembly and to ensure that the elastic connector 6 will not loosen or shift during operation. This firm 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 the stable output of sound quality and the high efficiency of the speaker in long-term operation. The second interlocking edge 62 fits with the diamond diaphragm 1, which can further fix the diaphragm and the skeleton 3 to form a tight but elastic connection, so that the diaphragm can vibrate stably when driven by signals of different frequencies and intensities, avoiding excessive vibration or reverse distortion, 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 a stress buffering effect of the elastic material, so that the connector can maintain a high elastic recovery ability when subjected to external vibration and impact. The advantage of this design is that when the speaker is working, vibration will be transmitted through the elastic connector 6, and the presence of the groove can effectively alleviate this vibration, reduce the impact of vibration on the diaphragm and the fixed bracket 5, and avoid sound quality attenuation or distortion caused by vibration. In addition, the reverse fit between the inner groove 63 and the convex groove 64 can also disperse stress to a certain extent, reduce local stress concentration, and thus extend the service life of the speaker assembly. The design of the inner groove 63 and the convex groove 64 can also provide 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 durability of the overall structure. During long-term use, the design of the continuous groove group helps to reduce fatigue damage caused by frequent vibration, ensures that the speaker assembly can withstand high-intensity use for a longer period of time, and avoids loose connections or component damage due to material fatigue.
[0037] In one embodiment, an arcuate transition structure is further included, which includes a first transition piece 71 and a second transition piece 72. The first fitting edge 61 and the convex groove 64 are connected by the first transition piece 71, and the second fitting edge 62 and the inner groove 63 are connected by the second transition piece 72. The outer sides of the first transition piece 71 and the second transition piece 72 are both provided with staggered trapezoidal ridges, and the inner groove 63 and the convex groove 64 are provided with wedge-shaped clamping points corresponding to the trapezoidal ridges. The continuous groove group is connected to the arcuate transition structure by the engagement and embedding of the trapezoidal ridges and the wedge-shaped clamping points.
[0038] In this embodiment, the connection between the first transition piece 71, the first engaging edge 61, and the convex groove 64 provides an effective transmission path. The transition effect of the first transition piece 71 ensures a stable connection between the diaphragm and the fixed bracket 5. During the operation of the speaker, the diaphragm needs to vibrate precisely on the fixed bracket 5, and the stability of this vibration has a crucial impact on the sound quality. The first transition piece 71 ensures the fixation of the engaging edge and the good fit of the convex groove 64, avoiding the problem of unstable vibration caused by a loose connection, thereby improving the sound quality of the speaker. The connection between the second transition piece 72, the second engaging edge 62, and the inner groove 63 is similar to the first transition piece 71. The inner groove 63 is part of the curved portion. The connection of the second transition piece 72 ensures that the inner groove 63 can make precise contact with the second engaging edge 62 and maintain stability during vibration. This design can effectively control the deformation of the inner groove 63 and avoid the phenomenon of sound quality degradation or distortion caused by structural instability caused by vibration. The second transition piece 72 not only provides the necessary structural support but also provides the diaphragm with the necessary degrees of freedom, enabling it to vibrate efficiently under the action of the drive signal, ensuring high-fidelity sound output. In the design of the outer edge of the arcuate transition structure, the staggered trapezoidal ridges enhance the stability and firmness of the connection. The trapezoidal ridges, in conjunction with the wedge-shaped snap points, provide a tighter and more reliable connection between the various components. When the arcuate transition structure is connected to the continuous groove group through the interlocking engagement of the trapezoidal ridges and the wedge-shaped snap 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 snapping process tighter, preventing loosening or falling off due to vibration, and ensuring that the speaker can maintain its reliability for a long time even under high-intensity vibration.
[0039] In one embodiment, a plurality of circular through holes 31 are provided on the side of the skeleton 3, and the through holes are located above the gap between the polar plate 24 and the magnetic iron 22. A porous adjustment net is provided in the circular through hole 31, and the porous adjustment net is composed of multiple layers of staggered mesh sheets.
[0040] In this embodiment, the circular through-holes 31 on the sides of the frame 3 act as air passages, allowing air to flow within the speaker assembly, particularly above the gap between the polar plate 24 and the magnetic conductor 22. When the speaker is operating, the rapid vibration of the diaphragm triggers air flow and pressure fluctuations. By providing these circular through-holes 31, air can flow freely within the speaker, effectively mitigating the negative effects caused by uneven airflow pressure. The regulating net is composed of multiple layers of interlaced mesh. This interlaced design improves the uniformity of air flow and can better regulate the speed and distribution of airflow. Because the operating principle of the speaker assembly involves the generation and propagation of sound waves, any uneven airflow can cause distortion in the audio output. The multiple layers of interlaced mesh change the direction and speed of the airflow, allowing the air to be more evenly distributed as it passes through these meshes, thereby avoiding the degradation of sound quality caused by unstable airflow. High- and low-frequency sound output, in particular, is significantly affected by uneven airflow. The design of the regulating net effectively avoids this problem and improves the sound quality of the speaker. The porous control mesh, composed of multiple layers of interlaced mesh, enhances its overall rigidity, making it less susceptible to deformation when subjected to fluctuations in air pressure within the speaker, thereby ensuring stable airflow. As air passes through these interlaced mesh layers, it is filtered and diverted by each layer, effectively preventing system instability or noise interference caused by sudden airflow fluctuations. This multi-layered design ensures the speaker maintains a relatively stable operating state, further enhancing the fidelity and stability of the sound.
[0041] In one embodiment, a conical clip edge is provided on the outer side of the porous adjustment net, and the outer surface of the conical clip edge is provided with anti-slip grooves. A conical hole corresponding to the conical clip edge is provided on the inner side of the circular through hole 31. The porous adjustment net and the circular through hole 31 are connected by the bite and interlocking of the conical clip edge and the conical hole.
[0042] In this embodiment, the conical clip edge realizes a stable connection between the porous adjustment net and the circular through hole 31, thereby enhancing the convenience of installation. The anti-slip pattern prevents the conical clip edge from slipping off easily during the installation process, thereby ensuring the structural stability and durability of the speaker assembly. The occlusal connection between the conical clip edge and the conical hole enables the porous adjustment net to fit tightly within the circular through hole 31, effectively preventing air leakage and further improving the working efficiency of the speaker assembly. In addition, this design is also convenient for subsequent maintenance and replacement. When the porous adjustment net needs to be cleaned or replaced due to long-term 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 short, the occlusal connection design between the conical clip edge and the conical hole provides a strong guarantee for the performance improvement and ease of use of the speaker assembly.
[0043] In one embodiment, a protective cover 8 is further included. The protective cover 8 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 arcuate 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 arcuate surface 812. The arcuate surface 812 is fixedly connected to the elastic connector 6. The annular base 811 is disposed around the outside of the fixed bracket 5. A spiral insert is disposed on the inside of the first circular ring 81. An arcuate convex pattern is disposed on one end of the arcuate connector 83 adjacent to the first circular ring 81. The first circular ring 81 and the arcuate connector 83 are connected by extrusion and interlocking the spiral insert and the arcuate convex pattern. A dust screen is disposed between every two arcuate connectors 83.
[0044] In this embodiment, the first circular ring 81 serves as the main structural component of the protective cover 8. Its annular base 811 is arranged around the outer side of the fixed bracket 5 and includes a curved surface 812 that is fixedly connected to the elastic connector 6. This design allows the protective cover 8 to be firmly fixed to the other components of the speaker, preventing the protective cover 8 from loosening or shifting when the speaker is operating, thereby enhancing the structural stability of the speaker assembly. The fixed connection between the curved 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 forces. A spiral groove is designed on the inner side of the first circular ring 81. The provision of the spiral groove allows the various annular components to fit tightly together, preventing the 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 firmness, but also maintains a high degree of convenience during installation and removal. Multiple arcuate connectors 83 are connected to the first circular ring 81. Each arcuate connector 83 has an arcuate ridge at one end. These ridges cooperate with the spiral inserts to securely connect the arcuate connector 83 to the first circular ring 81 through a squeeze-fitting mechanism. The arcuate connectors 83 are designed to provide excellent elasticity and durability, ensuring connection strength while also adapting to vibration and deformation during speaker operation, preventing excessive wear or loosening. The interaction between the spiral inserts and the arcuate ridges creates a stable and reliable connection between the arcuate connector 83 and the first circular ring 81. This connection not only improves the overall strength of the protective cover 8 but also enhances the speaker's stability during long-term use. A dust screen is installed between each pair of arcuate connectors 83. Its primary function is to prevent external dust or impurities from entering the speaker, particularly the diaphragm area covered by the protective cover 8. The intrusion of dust or impurities can not only cause physical damage to the diaphragm but also affect the speaker's sound quality. The dust screen effectively prevents dust from entering, protecting the speaker's internal structure and sound quality. This design effectively extends the speaker's lifespan, reduces maintenance frequency, and improves the user experience.
[0045] In one embodiment, a second groove 251 and a third groove 252 are provided at 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 accommodating cavity 25, and the third groove 252 is provided on the outside of the second groove 251, and a part of the gap is formed between the third groove 252 and the upper inner side of the magnetic iron 22 and the third groove 252, and the bottom of the second groove 251 is provided with heat dissipation fins, which are evenly distributed circumferentially along the bottom of the second groove 251.
[0046] In this embodiment, a second groove 251 and a third groove 252 are provided at the inner bottom of the magnetic iron 22. The second groove 251 is deeper than the third groove 252. The second groove 251 is located at the bottom of the accommodating cavity 25, while the third groove 252 is located outside the second groove 251. This design makes the internal structure of the magnetic iron 22 more compact and provides better physical support and functional separation for the speaker. The layout and depth difference of the two grooves determine their relationship, allowing the entire assembly to achieve both structural strength and heat dissipation. Heat dissipation fins are installed at the bottom of the second groove 251. The fins are evenly distributed around the bottom of the second groove 251, effectively improving the heat dissipation efficiency of the speaker assembly. The heat dissipation fins enhance heat dissipation through their increased surface area, helping to promptly release heat generated during speaker operation, thereby preventing overheating. Heat accumulation can not only affect speaker performance but can also cause component damage or shorten service life. Therefore, this structural design significantly improves heat dissipation performance, ensuring stable operation of the speaker under high loads or long-term operation. A gap is formed between the third groove 252 and the upper inner side of the magnetic iron 22. The existence of the gap helps to enhance the fluidity of the airflow inside the speaker, improve the heat exchange and airflow distribution inside the speaker, and thus further optimize the heat dissipation effect. The size of the gap and its coordination with the third groove 252 provide a certain amount of space for the structure of the speaker, so that the heat dissipation fins can fully play their role, while also avoiding the problem of poor heat dissipation caused by excessive sealing or overly compact structural design. By precisely controlling the distribution of the heat dissipation fins and the size of the gap, it is possible to effectively prevent the heat generated by the speaker during high-load operation from accumulating in a certain local area, thereby ensuring that the speaker can maintain stable sound output under long-term high-power operation. The combination of the gap and the third groove 252 can also provide a smoother flow path for the heat inside the speaker, so that the heat dissipation efficiency of the entire system is optimized.
