Description

Technical Field

[0001] This invention relates to the field of audio, specifically to a multi-speaker anti-interference audio system. Background Technology

[0002] With the rapid development of audio-visual entertainment, public address systems, and intelligent audio-visual systems, multi-speaker systems have become a mainstream market demand due to their wider sound field coverage and richer sound quality. In the design and application of multi-speaker systems, the mutual interference of sound waves generated when multiple speakers operate simultaneously is one of the core technical challenges. Sound wave interference can lead to sound quality distortion and a chaotic sound field, severely impacting the user's listening experience. Therefore, how to suppress mutual interference between multiple speakers through reasonable structural design and ensure the pure sound output of each speaker has become a key direction in the research and development of multi-speaker system technology. The reliability and stability of related anti-interference structures directly determine the market competitiveness of audio products. In the existing anti-interference technology for multi-speaker audio systems, the mainstream mechanical structure design involves setting rigid partitions and porous sound-absorbing panels between multiple speakers. The partitions separate each speaker into an independent mounting chamber. The technical principle is to use the physical barrier effect of the rigid partitions to prevent the sound waves generated by one speaker from directly propagating to the mounting chamber of another speaker, thereby reducing direct sound wave interference. Under the vibrations generated during long-term operation of the audio system, the porous sound-absorbing panel is prone to displacement and loosening, resulting in gaps between the panel and the sound wave transmission components. These gaps become channels for sound wave propagation, allowing redundant sound waves generated by one speaker to bypass the rigid partition and propagate to the mounting chambers of other speakers. This causes mutual interference between multiple speakers, ultimately leading to distortion and reduced clarity in the audio playback, failing to meet users' demands for high-quality sound. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a multi-speaker anti-interference audio system, which solves the problem that existing multi-speaker audio systems are prone to interference and have poor sound quality due to gaps between the honeycomb panel and the sound-absorbing pad.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a multi-speaker anti-interference audio system, comprising an audio body and two speakers installed in the audio body, wherein a honeycomb plate is provided at the front end of each of the two speakers, and a gap elimination component is provided on the outer periphery of each of the two speakers, and a dustproof and cover component is provided on the side of the audio body near the speakers. Each of the gap-eliminating components includes an independent isolation chamber, one side of which is fixedly connected to one side of the honeycomb panel. The independent isolation chamber contains a sound-absorbing pad layer. An annular rotating plate is fixedly connected to the outer periphery of the honeycomb panel. A U-shaped groove is formed in the annular rotating plate. Multiple guide rods are slidably arranged in the annular rotating plate.

The first mounting base is fixedly connected to the outer wall of the independent isolation chamber. The bottom end of the screw is rotatably disposed inside the first mounting base, and an L-shaped movable plate is threaded onto the outer periphery of the screw.

[0006] Preferably, the dustproof and cover-proof assembly includes a protective cover, which is rotatably disposed on the front side of the honeycomb panel. A rotating component is fixedly connected to the inner wall of the protective cover. A first connecting rod is rotatably disposed on the side of the rotating component near the honeycomb panel. A fixed plate is rotatably connected to the other end of the first connecting rod. A second connecting rod is also rotatably disposed on the side of the rotating component with the first connecting rod. The other end of the second connecting rod is rotatably connected to the side of the fixed plate away from the honeycomb panel. A first fixed post is fixedly connected to the side of the rotating component away from the first connecting rod. A second spring is fixedly connected to the lower end of the first fixed post. A second fixed post is fixedly connected to the other end of the second spring. The second fixed post is disposed on one side of the fixed plate.

[0007] Preferably, the first mounting base has a groove inside to restrict the rotation track of the card block, the L-shaped moving plate is slidably connected inside the first mounting base, and the bottom end of the L-shaped moving plate is slidably inserted into the card block.

[0008] Preferably, the sound-absorbing pad is accommodated in the inner wall of the U-shaped groove, and the inner wall of the U-shaped groove is in contact with the edge of the sound-absorbing pad. The sound-absorbing pad is disposed on the rear side of the honeycomb plate. The guide rod is integrally disposed with the abutment post. The abutment post is slidably disposed in the inner wall of the U-shaped groove. The first spring is fixedly disposed in the inner wall of the annular rotating plate. One end of the first spring abuts against the inner wall of the U-shaped groove, and the other end of the first spring abuts against one side of the abutment post.

[0009] Preferably, the rotating component and the fixed plate are arranged on different horizontal lines, and the first connecting rod and the second connecting rod are arranged between the rotating component and the fixed plate.

[0010] Preferably, a second mounting base is fixedly provided on the side of the independent isolation chamber opposite to the first mounting base, and a rotating shaft is rotatably provided inside the second mounting base, the outer wall of the rotating shaft being rotatably connected to the inner wall of the annular rotating plate.

[0011] Preferably, a first support plate is fixedly provided on the top side of the speaker body near the honeycomb panel. The first support plate is T-shaped, and a dustproof and cover-proof assembly is provided below the first support plate.

[0012] Preferably, a second support plate is fixedly connected to one end of the fixing plate facing the speaker body, and the protective cover is disposed in front of the honeycomb panel.

[0013] Preferably, the guide rod and the abutment post are integrally formed, and the guide rod and the abutment post are arranged at equal angles along the circumferential direction on the inner wall of the annular rotating plate, with the front end of the guide rod extending out of the inner wall of the annular rotating plate.

[0014] This invention provides a multi-speaker anti-interference audio system. It has the following beneficial effects: 1. The gap elimination component of this invention sets independent isolation chambers around the two speakers, accommodates the sound-absorbing pad layer in the isolation chambers and clamps it to the back of the honeycomb panel. At the same time, the guide rod in the annular rotating plate cooperates with the first spring on the outer periphery to drive the abutment column to elastically abut against the sound-absorbing pad layer, realizing the clamping and elastic abutment gap elimination between the honeycomb panel and the sound-absorbing pad layer. This solves the problem that the gap between the honeycomb panel and the sound-absorbing pad layer can easily cause mutual interference between multiple speakers in daily use, effectively improves the anti-interference capability of multi-speaker audio, and ensures that the sound quality of each speaker is not affected by each other when playing. 2. The present invention's disassembly component, by rotating the screw inside the first mounting base, drives the L-shaped moving plate on the outer periphery to move along the base and disengage from the matching groove of the locking block. Then, the annular rotating plate integrated with the locking block is rotated, causing the honeycomb plate to rotate around the rotating shaft. This allows the old sound-absorbing pad layer to be removed without removing the honeycomb plate, solving the problem of the sound-absorbing pad layer becoming loose and losing its sound wave absorption capacity after long-term high-load use, making replacement inconvenient. The operation is convenient and efficient, and can maintain the anti-interference effect of the gap elimination component in a timely manner. 3. The dustproof and cover-proof assembly of this invention uses a protective cover to shield the honeycomb panel in normal operation, reducing dust from entering and clogging the honeycomb panel's through holes. When in use, flipping the protective cover causes the rotating component to flip synchronously. The first and second connecting rods support the rotating component, while the second spring provides tension, ensuring the protective cover is stably fixed after flipping to be flush with the first support plate. This solves the problem of dust clogging the honeycomb panel and affecting sound transmission, and also provides support for the speaker after flipping, preventing the speaker from being covered and affecting sound quality. It ensures both the sound transmission performance of the honeycomb panel and the stability of the protective cover after operation, without interfering with the normal use of the speaker.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see the appendix Figure 1 -Appendix Figure 4This invention provides a multi-speaker anti-interference audio system, including an audio body 1. Two speakers 8 are installed inside the audio body 1. Each speaker 8 is the core sound-generating component, providing the foundation for the audio's sound output. A honeycomb plate 5 is provided at the front end of each speaker 8. The honeycomb plate 5 can regulate and conduct the sound output from the speaker 8, and simultaneously provides a fixed mounting carrier for the independent isolation chamber 41 and the annular rotating plate 42 in the gap elimination assembly 4. A gap elimination assembly 4 is provided on the outer periphery of each speaker 8. The gap elimination assembly 4 can effectively isolate the mutual interference generated when the two speakers 8 are working, ensuring the purity of the sound output.

[0019] Specifically, the speaker body 1 carries the speaker 8, honeycomb panel 5, and gap elimination component 4, achieving coordinated protection of multi-speaker sound generation and anti-interference. The speaker 8 serves as the core to complete the sound signal output, the honeycomb panel 5 regulates the sound wave transmission to improve clarity, and the gap elimination component 4 isolates the sound wave interference between speakers, solving the problem of poor sound quality caused by mutual interference in existing multi-speaker audio systems and improving the reliability of audio generation.

[0020] Please see the appendix Figure 2 -Appendix Figure 8 The gap-eliminating assembly 4 includes an independent isolation chamber 41, which provides a closed space for the sound-absorbing pad 43 and is positioned by fixing it to the honeycomb panel 5. An annular rotating plate 42 is fixed to one side of the independent isolation chamber 41, providing a mounting carrier for the U-shaped groove 44, guide rod 45 and first spring 47. At the same time, the guide rod 45 slides. The annular rotating plate 42 has a U-shaped groove 44 inside, which provides a placement space for the sound-absorbing pad 43 and limits its position by edge fitting. At the same time, it allows the abutment post 46 to slide. The sound-absorbing pad 43 is located on the rear side of the honeycomb panel 5 and can absorb redundant noise from the operation of the speaker 8, enhancing anti-interference. In effect, multiple guide rods 45 are slidably arranged inside the annular rotating plate 42. The guide rods 45 and the abutment posts 46 are integrally formed and distributed at equal angles along the circumference. The front end of the abutment posts 46 extends out of the inner wall of the annular rotating plate 42 to ensure stable sliding stroke. At the same time, the abutment posts 46 are slidably arranged on the inner wall of the U-shaped groove 44, which can press against the sound-absorbing pad 43 to ensure that it fits tightly against the inner wall of the U-shaped groove 44. A first spring 47 is arranged on the outer periphery of the guide rods 45. The two ends of the first spring 47 abut against the inner wall of the U-shaped groove 44 and the abutment posts 46 respectively. Through the elastic force, it provides a continuous pressing force to ensure stable abutment state. Specifically, the gap elimination component 4 solves the problems of mutual interference and poor working stability of existing multi-speaker audio systems. The independent isolation chamber 41 provides space for the positioning and installation of the sound-absorbing pad 43. The U-shaped groove 44 is adapted to limit the sound-absorbing pad 43 and provides sliding space for the abutment post 46 and guide rod 45 to ensure sliding stability. The sound-absorbing pad 43 absorbs redundant sound waves from the speaker 8 and enhances the anti-interference effect. The abutment post 46 presses against the sound-absorbing pad 43 to ensure that the sound-absorbing pad 43 fits tightly with the U-shaped groove 44. At the same time, the first spring 47 provides continuous pressing force through elastic force to maintain a stable abutment state and effectively improve the purity of the sound output.

[0021] Please see the appendix Figure 2 Appendix Figure 5 and attached Figure 8 The disassembly assembly 6 includes a locking block 64, a first mounting base 61, a screw 62, and an L-shaped movable plate 63. The disassembly assembly 6 is the core structure for easily disassembling and stably connecting the annular rotating plate 42 and the independent isolation chamber 41, providing convenient support for the maintenance and replacement of the gap-eliminating assembly 4. The locking block 64 is fixed to the outside of the annular rotating plate 42, and a matching groove 65 is provided inside the locking block 64. The matching groove 65 provides fitting space for the screw 62 to be inserted and lowered, achieving precise docking between the screw 62 and the locking block 64. The first mounting base 61 is located on the outer periphery of the matching groove 65 and is fixedly connected to the outer wall of the independent isolation chamber 41, providing a mounting space for the screw 62. 2. A stable rotating mounting carrier is provided. The slot inside the first mounting base 61 can restrict the rotation track of the locking block 64, ensuring the accuracy of the docking between the locking block 64 and the first mounting base 61. The bottom end of the screw 62 is rotatably set inside the first mounting base 61. The L-shaped moving plate 63 with threads on the outer circumference of the screw 62 is slidably connected inside the first mounting base 61, and the bottom end of the L-shaped moving plate 63 can be slidably inserted into the locking block 64. The rotation of the screw 62 can drive the L-shaped moving plate 63 to rise and slide, realizing the locking and separation of the L-shaped moving plate 63 and the locking block 64, thereby completing the disassembly and assembly of the annular rotating plate 42 and the independent isolation chamber 41.

[0022] Specifically, the disassembly component 6 solves the problems of inconvenience in replacing the existing sound-absorbing pad 43 and the potential impact on the function of the gap-eliminating component 4 after replacement. When the sound-absorbing pad 43 needs to be replaced, the screw 62 rotates to generate driving force, which moves the outer L-shaped moving plate 63 along the first mounting base 61, releasing the lock between the L-shaped moving plate 63 and the matching groove 65. Then, the annular rotating plate 42 and the locking block 64 are pulled to rotate synchronously, causing the integrated honeycomb plate 5 to flip along the rotating shaft 10, ensuring that the annular rotating plate 42 flips smoothly. Finally, the sound-absorbing pad 43 is exposed, and the old pad can be replaced without disassembling the honeycomb plate 5, thus improving the convenience of replacement and the working stability of the gap-eliminating component 4.

[0023] Please see the appendix Figure 1 Appendix Figure 3 -Appendix Figure 7 The dustproof cover assembly 7 includes a protective cover 71. The dustproof cover assembly 7 is rotatably mounted on the side of the speaker body 1 near the honeycomb panel 5 to prevent dust and debris from entering and protect the honeycomb panel 5 and the speaker 8. A rotating component 72 is fixedly connected to the inner wall of the protective cover 71. The rotating component 72 provides a rotating mounting carrier for the first connecting rod 77 and the second connecting rod 78. The rotating component 72 and the fixed plate 73 are positioned on different horizontal lines. The first connecting rod 77 and the second connecting rod 78 are rotatably connected to the side of the rotating component 72 near the honeycomb panel 5, respectively. The second connecting rod 78 at the other end is rotatably connected to the fixed plate 73. The first connecting rod 77 and the second connecting rod 78 are arranged between the rotating part 72 and the fixed plate 73, which cooperate to realize the smooth rotation and opening and closing of the protective cover 71. The rotating part 72 is fixedly connected to the side away from the first connecting rod 77 with the first fixed post 74. The fixed plate 73 is provided with the second fixed post 75 on one side. The first fixed post 74 and the second fixed post 75 are connected with the second spring 76, which can provide elastic support for the rotation and reset of the protective cover 71 through the elastic force of the second spring 76.

[0024] Specifically, the dustproof cover assembly 7 solves the problems of unstable protection and muffled sound caused by obstructing sound-producing components in existing audio dustproof structures. After the protective cover 71 is flipped and positioned flush with the horizontal plate of the first support plate 2, it forms a support and protection to prevent foreign objects from covering the honeycomb plate 5 and causing muffled sound. The first connecting rod 77 and the second connecting rod 78 ensure the smooth flipping of the rotating part 72 and the protective cover 71 through the stable support and guidance provided by the fixing plate 73. The second spring 76 between the first fixing post 74 and the second fixing post 75 transmits the force. By pulling the second fixing post 76, the tension is generated to maintain the flat positioning of the protective cover 71 and ensure the stability of the protection. This enhances the support reliability for the flipping and positioning of the protective cover 71. No additional fixing structure is required, which greatly improves the stability and convenience of dustproof protection.

[0025] In addition, a T-shaped first support plate 2 is fixedly installed on the top side of the speaker body 1 near the honeycomb panel 5. A dustproof cover assembly 7 is installed below the first support plate 2 to provide stable installation support for the dustproof cover assembly 7. A second support plate 3 is fixedly connected to the end of the fixing plate 73 facing the speaker body 1 to further improve the installation stability of the fixing plate 73. A second mounting base 9 is fixedly installed on the opposite side of the independent isolation chamber 41 away from the first mounting base 61. A rotating shaft 10 is rotatably installed inside the second mounting base 9. The outer wall of the rotating shaft 10 is rotatably connected to the inner wall of the annular rotating plate 42, providing a rotatable connection structure between the annular rotating plate 42 and the independent isolation chamber 41. Together with the disassembly assembly 6, it enables convenient disassembly, assembly and maintenance of the two.

[0026] Specifically, the protective cover 71 solves the problems of easy dust blockage and unstable dustproof structure of the honeycomb panel 5 in existing audio equipment, and realizes reliable protection of the honeycomb panel 5, stable installation and convenient maintenance. The protective cover 71, together with the first support plate 2 and the second support plate 3, forms a protective barrier to block dust and prevent the through holes of the honeycomb panel 5 from being blocked. The second mounting base 9 and the rotating shaft 10 connect the annular rotating plate 42 and the independent isolation chamber 41. The disassembly component 6, together with the rotating shaft 10, enables convenient disassembly and assembly of the two without complicated operation, thereby improving the reliability of protection and the convenience of maintenance.

[0027] Working principle: A protective cover 71 is provided on the side of the speaker body 1 facing the honeycomb panel 5. The protective cover 71, together with the first support plate 2 and the second support plate 3, protects the honeycomb panel 5 and reduces dust from entering the honeycomb panel 5 during normal operation, thus preventing blockage of the through holes inside the honeycomb panel 5. When a multi-speaker anti-interference speaker is required, the protective cover 71 in the dustproof cover assembly 7 is flipped to be flush with the horizontal plate of the first support plate 2. During the flipping process, the protective cover 71 drives the rotating part 72 integrated with it to flip synchronously. The rotating part 72 and the fixed plate 73 are connected by a parallel first connecting rod 77 and a second connecting rod 78. The rotating part 72 is connected to the fixed plate 73, which provides support for the rotation of the rotating part 72. The rotating part 72 and the fixed plate 73 are each provided with the same first fixed post 74 and second fixed post 75. The first fixed post 74 and the second fixed post 75 are connected by a second spring 76. When the protective cover 71 drives the rotating part 72 to rotate, it will drive the first fixed post 74 to move, which will pull the second spring 76. When the protective cover 71 is rotated to be flush with the horizontal plate of the first support plate 2, the second spring 76 can provide tension. After the protective cover 71 is rotated, it provides support for the speaker body 1 and prevents something from accidentally covering the honeycomb plate 5, which would cause muffled sound. After flipping over the protective cover 71, turn on the speaker body 1 and play music. During the playback, the independent isolation chamber 41 on the outside of the two speakers 8 and the sound-absorbing pad 43 can provide sound insulation. The sound-absorbing pad 43 is sandwiched between the honeycomb plate 5 and the independent isolation chamber 41, and the guide rod 45 in the annular rotating plate 42 will directly contact the sound-absorbing pad 43. The guide rod 45 is provided with a first spring 47 on its outer periphery. The guide rod 45 is provided with an abutment post 46 on the side facing the speaker 8. The diameter of the abutment post 46 is larger than that of the first spring 47. When the honeycomb plate 5 and the sound-absorbing pad 43 are clamped, they will elastically abut against each other. By clamping and elastically abutting, the gap between the honeycomb plate 5 and the sound-absorbing pad 43 is eliminated. The gap elimination component 4 realizes the mutual interference prevention between the two speakers 8 and prevents the two speakers 8 from being affected by each other's sound quality during playback. After long-term use, the sound-absorbing pad 43 on the outside of the speaker 8 will become loose due to high load and lose its sound wave absorption capacity. The sound-absorbing pad 43 needs to be replaced, otherwise it will affect the function of the gap elimination component 4. Rotate the screw 62 along the first mounting base 61 in the split assembly 6. The rotation of the screw 62 drives the L-shaped moving plate 63 on the outer periphery of the screw 62 to move along the first mounting base 61 until the bottom end of the L-shaped moving plate 63 leaves the matching groove 65 in the locking block 64. Then rotate the annular rotating plate 42 integrated with the locking block 64, so that the annular rotating plate 42 drives the integrated honeycomb plate 5 to rotate along the rotating shaft 10 on the other side. Then remove the exposed sound-absorbing pad 43 from the independent isolation chamber 41 and replace it with a new sound-absorbing pad 43.
