[0036] The plurality of diaphragm assemblies comprise an edge 1, the edge 1 is fixedly connected to the top of the upper protective shell 2, a carbon fiber layer 16 is fixedly connected to the bottom side of the end of the edge 1, the carbon fiber layer 16 can respond to the vibration signals transmitted by the voice coil 18 very quickly and accurately due to its excellent characteristics of high strength and high rigidity. A butyl rubber layer 15 and a glass fiber layer 14 are also fixedly connected to the bottom side of the end of the edge 1, the butyl rubber layer 15 has a unique good damping characteristic. During the vibration of the diaphragm, it can absorb and store part of the vibration energy, and then slowly release the stored energy when the vibration is in a specific cycle stage. The glass fiber layer 14 has a relatively affordable cost, and has a good balance of rigidity and toughness. It can be processed into a thin and effective layer, can stably propagate sound vibration, and has good chemical stability, can withstand a certain degree of temperature change and chemical corrosion, and provides reliable protection for the long-term stable use of the diaphragm. A dust cover 19 is fixedly connected to the bottom of the glass fiber layer 14, and the butyl rubber layer 15 and the carbon fiber layer 16 are also fixedly connected to the outer side of the dust cover 19. The dust cover 19 plays a role in protecting the internal structure of the diaphragm, preventing dust and other impurities from entering and affecting the normal vibration of the diaphragm, and on the other hand, it is tightly connected with each layer of the diaphragm, and also vibrates during the vibration and sound generation of the diaphragm, and plays an auxiliary role in the propagation of sound and the echo effect.

The sound-absorbing cottons 7 can absorb excess sound energy, avoid excessive reflection of sound inside to produce chaotic echo, make the sound more pure, and thus highlight the echo effect of the horn itself.
[0037] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application. Figure 2 Figure 3 The sound amplification assembly comprises a support 10 fixedly connected to the inner side of the end of the lower protective shell 5, the inner side of the end of the support 10 is fixedly connected with a sound post 8, and the bottom of the support 10 is fixedly connected with a yoke 11. The sound post 8 is fixed to the inner side of the end of the support 10, and after the diaphragm vibrates to generate sound, the sound will propagate to the sound post 8. The sound post 8 plays a precise guiding and certain enhancement role on the sound according to its special shape and acoustic characteristics. The bottom of the carbon fiber layer 16 is fixedly connected with a coil holder 17, the end of the coil holder 17 is fixedly connected with a centering branch 9, and the end of the centering branch 9 is fixedly connected to the inner side of the end of the plurality of supports 10. The coil holder 17 can stably and accurately transmit the power transmitted by the voice coil 18 to the carbon fiber layer 16 connected above, thereby driving the entire multilayer diaphragm assembly to stably and regularly vibrate, and finally realizing the purpose of converting electric energy into stable and high-quality sound energy and propagating outward.
[0038] Referring to Figure 3 , Figure 4 and Figure 5The connecting assembly comprises two fixing rings 3, one of which is fixedly connected to the outer side of the end of the upper protective shell 2, and the other of which is fixedly connected to the outer side of the end of the lower protective shell 5, and a plurality of bolts 4 are installed on the inner sides of the two fixing rings 3. The upper protective shell 2 and the lower protective shell 5 are aligned, the corresponding fixing rings 3 are attached, and then the bolts 4 are inserted and tightened, so that the two parts are firmly connected together to form the overall housing structure of the loudspeaker, facilitating the assembly process of the entire loudspeaker. When maintenance, replacement or debugging of the internal components of the loudspeaker is required, the bolts 4 are simply unscrewed, and the upper protective shell 2 and the lower protective shell 5 can be easily separated, making it easy for the operator to access the internal components, greatly improving the convenience of maintenance. The lower protective shell 5 is fixedly connected to the inner side of the bottom of the lower protective shell 5, and the plurality of brackets 10 are fixedly connected to the bottom side of the end of the yoke 11. The yoke 11 and the magnet 13 are fixedly connected between the yoke 11 and the glass fiber layer 14. The yoke 11 and the magnet 13 are slidably connected to the inner sides of the yoke 11 and the magnet 13. The yoke 18 is slidably connected to the outer side of the yoke 12. When audio current passes through the yoke 18, the yoke 18 is subjected to the action of the Ampere force in the magnetic field formed by the yoke 11, the magnet 13 and the yoke 12 according to the principle of electromagnetic induction. The yoke 18 is fixedly connected to the outer side of the coil holder 17, and the coil holder 17 is also slidably connected to the inner sides of the yoke 11 and the magnet 13. The coil holder 17 is also slidably connected to the outer side of the yoke 12. The yoke 18 and the coil holder 17 are slidably connected to the inner sides of the yoke 11 and the magnet 13 and the outer side of the yoke 12, respectively, to ensure that their movement trajectories can be along the axial direction of the magnetic field. That is, the yoke 18 and the coil holder 17 can stably reciprocate in the space defined by these components under the drive of the Ampere force, and further transmit the motion to the diaphragm assembly and other structures connected thereto, to finally drive the diaphragm to vibrate and sound, realizing the process of converting electrical energy into sound energy, so that the loudspeaker can normally emit sound.
[0039] Working principle: When audio current passes through the yoke 18, the yoke 18 will move in the magnetic field according to the principle of electromagnetic induction. The magnetic field is formed by the yoke 11, the magnet 13 and the yoke 12. The yoke 18 is fixed to the outer side of the coil holder 17, so the movement of the yoke 18 drives the movement of the coil holder 17. The end of the coil holder 17 is connected to the centering piece 9, which stabilizes the movement direction of the coil holder 17, ensuring that it can move linearly in the magnetic field along the axial direction. At the same time, the movement of the coil holder 17 is transmitted to the multi-layer diaphragm assembly composed of the carbon fiber layer 16, the butyl rubber layer 15 and the glass fiber layer 14.
[0040] The carbon fiber layer 16 has the characteristics of high strength and high rigidity, and can quickly and accurately respond to the vibration signal transmitted by the voice coil 18, effectively transmit the vibration to the air, produce clear and loud sound, and stably vibrate for a long time. The butyl rubber layer 15 has good damping characteristics and can absorb and store part of the vibration energy. When the diaphragm vibrates, the butyl rubber layer 15 will produce elastic deformation, temporarily store part of the energy, and then release it at the appropriate stage of the vibration cycle, slowing down the decay process of the sound and prolonging the duration of the sound, thereby enhancing the echo effect. The glass fiber layer 14 has relatively low cost and good rigidity and toughness. It can be made very thin and can effectively transmit sound vibration. It has good chemical stability and can resist certain temperature changes and chemical corrosion to ensure the service life of the diaphragm. In the multi-layer diaphragm structure, it cooperates with the other two layers to act on the generation of sound and the enhancement of echo. The multiple sound-absorbing cotton 7 on the outer side of the end of the glass fiber layer 14 can absorb and adjust part of the sound. It can absorb excess sound energy to avoid excessive internal reflection of sound and produce chaotic echoes, making the sound purer and highlighting the echo effect of the loudspeaker itself.
[0041] The sound post 8 is fixed to the inner side of the end of the support 10. When the diaphragm vibrates to produce sound, the sound propagates to the sound post 8. The sound post 8 can guide and enhance the sound, making the sound more effectively propagate outward. At the same time, the yoke 11 at the bottom of the support 10 is part of the magnetic field loop and plays a key role in the entire electromagnetic driving process, which indirectly affects the generation and propagation of sound. The perforated plate 6 at the bottom of the edge 1 can change the propagation direction and scattering characteristics of the sound. When the sound propagates from the diaphragm, the perforated plate 6 will make the sound more evenly distributed in space during propagation, increasing the number of reflections and scattering of the sound, thereby enhancing the echo effect.
[0042] The two fixing rings 3 are located on the outer side of the end of the upper protective shell 2 and the lower protective shell 5, and are connected by the multiple bolts 4 installed on the inner side. This connection method is convenient for disassembly and installation, and is convenient for maintenance and replacement of the internal components of the loudspeaker. Moreover, the appropriate tightness can ensure the tightness between the upper and lower protective shells, prevent sound leakage, and also avoid excessive extrusion of the internal components to affect their normal work.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for part of the technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent substitution, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
