[0031] Embodiment 2:

[0032] like Figure 1-Figure 10As shown, the tweeter 1 of the present invention is fixedly connected to the midrange speaker 3 through the connecting substrate 2. The tweeter 1 is a component responsible for playing high-frequency sounds. The tweeter 1 is mainly composed of a diaphragm, a voice coil, a magnet, a T-shaped iron, a washer and other structures. The midrange speaker 3 is mainly composed of a T-shaped iron, a sound guide hole 9, a magnet, a washer, a basin, a spring, a drum paper, a voice coil and other structures. The utility model is fixedly connected between the tweeter 1 and the midrange speaker 3 by a connecting substrate 2. The connecting substrate 2 provides a fixed basic support for other structural components. The connecting substrate 2 is provided with a tweeter electrode seat 4 and a midrange electrode seat 5. The tweeter electrode seat 4 and the midrange electrode seat 5 are both used to install electrical connection terminals. Since the speaker sound The wire of the voice coil is a thin copper wire that is easy to break, and the voice coil is connected to the drum paper. When playing sound, the movement of the copper wire can easily cause the vibration of the drum paper to change, resulting in sound distortion. Therefore, the electrical connection terminal on the tweeter electrode seat 4 is connected to the voice coil wire of the tweeter 1, and the electrical connection terminal on the midrange electrode seat 5 is connected to the voice coil wire of the midrange speaker 3, so that the external connection wire is directly connected to the voice coil indirectly through the electrical connection terminal, preventing the external connection wire from directly affecting the vibration of the voice coil and the drum paper through external force, thereby improving the sound quality of the speaker. The tweeter 1 includes a first T-shaped iron 6, a diaphragm, a voice coil, a magnet, and a washer, which constitute a tweeter 1 system. A T-shaped iron 6 is provided with a chamber 7. Since the volume of the tweeter 1 is small, the cavity inside the tweeter 1 is very small and it is very easy to generate resonance. By providing the chamber 7 on the convex column of the first T-shaped iron 6, the volume of the cavity inside the tweeter 1 is increased, and the sound quality of the tweeter 1 is improved. The midrange speaker 3 includes a second T-shaped iron 8, a sound guide hole 9, a magnet, a washer, a basin, a spring, a drum paper, and a voice coil to form a midrange speaker 3 system. The second T-shaped iron 8 is provided with a sound guide hole 9. The sound guide hole 9 is a through hole that runs through the front and back of the midrange speaker 3. It is generally set at the center of the speaker, or the position of the sound guide hole 9 and the position of the voice coil are the same as the center of the circle, and the bottom of the sound guide hole 9 is opposite to the drum paper of the tweeter 1. The setting is that the drum paper of the tweeter 1 is facing the bottom of the sound guide hole 9, so that the sound waves generated by the vibration of the drum paper of the tweeter 1 can be diffused to the outside through the sound guide hole 9, and the diameter of the drum paper of the tweeter 1 is less than or equal to the diameter of the sound guide hole 9, so that the sound waves can be smoothly transmitted to the outside, and fewer sound waves are reflected inside the tweeter 1 and then the vibration of the drum paper of the speaker box is improved, thereby improving the sound quality of the dry sound speaker, and a tweeter horn 10 is connected to the substrate 2 and located in the sound guide hole 9. The tweeter 1 diffuses the sound through the tweeter horn 10, thereby improving the directivity of the sound, smoothing the frequency response of the tweeter 1, reducing the frequency fluctuation caused by the characteristics of the speaker itself, reducing the acoustic distortion of the speaker, and providing a more balanced sound quality.

[0033] The tweeter horn 10 of the utility model includes an outer sound guide tube 11, an inner sound guide tube 12, and a cone 13. The outer sound guide tube 11 is fixedly connected to the inner sound guide tube 12 through a first connecting member 14, and the inner sound guide tube 12 is fixedly connected to the cone 13 through a second connecting member 15. In the coaxial mid-tweeter speaker 1 system of the utility model, the tweeter horn 10 plays an important role in improving sound quality and optimizing sound wave propagation. The tweeter horn 10 is composed of three parts: an outer sound guide tube 11, an inner sound guide tube 12, and a cone 13, which improves the propagation efficiency and directivity of sound. The outer sound guide tube 11 is the external structure of the tweeter horn 10, which is fixedly connected to the inner sound guide tube 12 through a first connecting member 14. The first connecting member 14 enables the outer sound guide tube 11 to stably support the inner sound guide tube 12 and ensures that the acoustic performance between the two is optimized. The inner sound guide tube 12 is located inside the outer sound guide tube 11. The inner sound guide tube 12 is fixedly connected to the cone 13 through the second connecting member 15. The design of the inner sound guide tube 12 further focuses and guides the sound waves, so that they pass through the cone 13 more concentratedly, improves the sound propagation efficiency, and reduces the interference of the sound waves inside the tweeter 10, thereby reducing the acoustic distortion. The cone 13 further focuses the sound waves and optimizes their propagation direction. The conical structure of the cone 13 allows the sound waves to be more concentrated when passing through, improves the directivity of the sound, and also helps to smooth the frequency response and reduce the frequency fluctuations caused by the characteristics of the speaker itself. Overall, the tweeter 10 is composed of an outer sound guide tube 11, an inner sound guide tube 12 and a cone 13, forming an efficient sound wave propagation system, which improves the sound quality of the tweeter 1, reduces the internal reflection and scattering of sound waves, reduces acoustic distortion, and provides users with a clearer and more balanced listening experience. In addition, the tweeter 10 works in coordination with the midrange speaker 3 to ensure the overall performance and sound quality of the entire coaxial mid-treble speaker 1 system.

[0034] The barrel cavity shapes of the outer sound-conducting tube 11 and the inner sound-conducting tube 12 of the utility model are both horn-shaped. In the coaxial mid-high frequency speaker 1 system of the utility model, the barrel cavity shapes of the outer sound-conducting tube 11 and the inner sound-conducting tube 12 are both designed to be horn-shaped, and the horn-shaped barrel cavity design is conducive to the diffusion and concentration of sound waves. The horn-shaped structure of the outer sound-conducting tube 11 and the inner sound-conducting tube 12 enables the sound waves to gradually expand along the barrel wall when passing through these components, thereby forming a wider sound wave diffusion angle at the exit, which not only improves the propagation efficiency of the sound waves, but also helps to form a more uniform sound field coverage, so that the audience can obtain a more consistent auditory experience regardless of which direction of the sound source they are in. The horn-shaped barrel cavity can reduce the reflection and scattering of the sound waves inside the tweeter horn 10. Since the path of the sound waves gradually expands along the barrel wall when propagating in the horn-shaped barrel cavity, this reduces the chance of reflection of the sound waves inside the barrel cavity, thereby reducing the possibility of mutual interference of the sound waves. This design effectively reduces acoustic distortion and improves the purity of the sound quality. In addition, the design of the horn-shaped barrel cavity also takes into account the synergistic effect with the cone 13. The cone 13 is located at the end of the inner sound guide tube 12, and its conical structure forms a gradual sound wave focusing process with the horn-shaped barrel cavity of the inner sound guide tube 12. This design allows the sound waves to gradually concentrate when passing through the inner sound guide tube 12, and then further focus under the action of the cone 13, ultimately achieving highly directional sound wave propagation. The horn-shaped barrel cavity design of the outer sound guide tube 11 and the inner sound guide tube 12 not only improves the propagation efficiency of the sound waves and the purity of the sound quality, but also forms a good synergistic effect with the cone 13, and together improves the acoustic performance of the entire tweeter 10. The design can provide users with a clearer and more balanced listening experience in the fields of audio equipment, car audio, and home theater systems.

[0035] The bottom of the tweeter horn 10 of the present invention is a concave spherical surface, and the drum paper of the tweeter 1 of the present invention is a convex spherical surface. The concave spherical surface at the bottom of the tweeter horn 10 is consistent with the shape of the drum paper of the tweeter 1, that is, the concave spherical surface at the bottom of the tweeter horn 10 and the drum paper of the tweeter 1 are concentric curved surfaces, and the diameter d1 of the concave spherical surface at the bottom of the tweeter horn 10 is greater than the diameter d2 of the drum paper of the tweeter 1, and the difference between d1 and d2 is in the range of 1.2mm-3.0mm.

[0036] The chamber 7 of the utility model is fixedly installed with sound-absorbing cotton 16, which is used to absorb standing waves in the chamber 7, eliminate noise and improve sound quality. In the design of the coaxial tweeter 1, the chamber 7 is a key structure inside the tweeter 1. The chamber 7 increases the cavity volume inside the tweeter 1 and improves the sound quality of the tweeter 1, but standing waves will be generated in the chamber 7. These standing waves are formed by the reflection of sound waves in the chamber 7. Standing waves will cause the sound quality to deteriorate, which is manifested as noise and distortion. In order to solve this problem, the utility model is fixedly installed with sound-absorbing cotton 16 in the chamber 7. The role of the sound-absorbing cotton 16 is multifaceted. It can not only absorb standing waves, but also eliminate noise, thereby significantly improving the sound quality of the speaker. The sound-absorbing cotton 16 can absorb the standing waves reflected and formed in the chamber 7 through its porous structure. This absorption effect reduces the interference of standing waves on the vibration of the diaphragm, thereby reducing the sound quality distortion caused by standing waves. Due to the existence of standing waves, unnecessary resonance and echo will be generated in the chamber 7, which will be converted into noise and affect the sound quality. The sound-absorbing cotton 16 can effectively absorb these noises, making the sound emitted by the tweeter 1 purer. By reducing the influence of standing waves and noise, the sound-absorbing cotton 16 helps to improve the overall sound quality. It enables the tweeter 1 to reproduce the details of high-frequency sounds more accurately and provide a clearer auditory experience. The use of the sound-absorbing cotton 16 helps to optimize the frequency response curve of the tweeter 1, reduce unnecessary frequency peaks and valleys, and make the frequency response of the speaker smoother and more linear. By reducing the sound wave interference in the chamber 7, the sound-absorbing cotton 16 also helps to enhance the positioning accuracy of the sound field. This is especially important for stereo systems and multi-channel systems because they rely on accurate sound field positioning to provide an immersive auditory experience. The fixed installation of the sound-absorbing cotton 16 also helps to enhance the structural stability of the chamber 7. As a filler, it can reduce the cavity effect inside the chamber 7, thereby reducing the mechanical noise caused by vibration.

[0037] The hole shape of the sound guide hole 9 of the utility model is horn-shaped, and the horn-shaped hole design enables the sound waves emitted by the tweeter 1 to be more evenly diffused to the external space when passing through the sound guide hole 9. This diffusion effect helps to form a wide sound field, so that the sound coverage range is wider, and the audience can get a consistent auditory experience regardless of their position. The design of the horn-shaped sound guide hole 9 helps to reduce the distortion of sound waves during propagation. Since the sound waves can diffuse more smoothly when passing through the sound guide hole 9, the compression and reflection of the sound waves at the hole mouth are reduced, thereby reducing the distortion of the sound waves and ensuring the naturalness and clarity of the sound. The shape of the horn-shaped sound guide hole 9 helps to control the propagation direction of the sound waves and improve the directivity of the sound waves. This directivity is particularly important for stereo systems and multi-channel systems because they rely on precise sound wave propagation directions to create an immersive auditory environment. The design of the horn-shaped sound guide hole 9 helps to smooth the frequency response curve of the midrange speaker 3. By reducing the unevenness of the sound waves at the hole, the horn-shaped sound guide hole 9 helps to reduce the peaks and valleys in the frequency response, making the frequency response of the midrange speaker 3 more balanced and linear. In addition to the improvement of acoustic performance, the design of the horn-shaped sound guide hole 9 also has a high aesthetics. This design adds a unique appearance feature to the speaker, making it more visually attractive.

[0038] In the coaxial mid-high frequency speaker 1 system of the utility model, the body 31 of the mid-range speaker 3 is made of mica paper. Mica paper (paper + mica sheet) has the flexibility of paper material and the rigidity of mica sheet material. Based on the unique physical and acoustic properties of mica paper, the mid-range speaker 3 has the characteristics of non-piercing high-frequency sound, full mid-frequency sound, and steady low-frequency sound, making the sound clear, soft, and clean, and improving the sound quality of the tweeter 1. As a lightweight and high-strength material, mica paper has good rigidity and internal damping properties, which enables it to produce less resonance when vibrating, thereby reducing sound wave distortion and providing purer sound quality. In addition, the internal structure of mica paper helps to absorb and disperse vibration energy, further reducing noise and resonance. Mica paper has good heat resistance and can remain stable in high temperature environments, which is crucial for the stability of the speaker when working for a long time or at high power output. Mica paper has a low affinity for moisture, so it has good moisture resistance, which allows the speaker to maintain a good working condition even in a humid environment. Mica paper is an environmentally friendly material, and its production process has little impact on the environment, which meets the environmental protection requirements of modern audio equipment. Mica paper has a good appearance texture, which can provide the speaker with an elegant and professional appearance design and enhance the overall beauty of the product. The high strength and wear resistance of mica paper make the carcass 31 of the mid-range speaker 3 more durable, able to resist wear and impact in daily use, and extend the service life of the speaker. Mica paper has high acoustic transparency, which means that it has little obstruction to the sound waves passing through it, helping to maintain the natural characteristics and details of the sound, providing a more realistic and clear listening experience.

[0039] The connection substrate 2 of the utility model is provided with a tweeter electrode seat 4 and a midrange electrode seat 5. The tweeter electrode seat 4 includes a tweeter positive electrode seat 17 and a tweeter negative electrode seat 18. The midrange electrode seat 5 includes a midrange positive electrode seat 19 and a midrange negative electrode seat 20. The tweeter electrode seat 4 and the midrange electrode seat 5 are both used to install electrical connection terminals. Since the wire of the speaker voice coil is a thin copper wire that is easy to break, and the voice coil is connected to the drum paper, when playing sound, the pulling of the copper wire easily causes the vibration of the drum paper to change, resulting in sound distortion. Therefore, the electrical connection terminal on the tweeter electrode seat 4 is connected to the voice coil wire of the tweeter 1, and the electrical connection terminal on the midrange electrode seat 5 is connected to the voice coil wire of the midrange speaker 3, so that the externally connected connection wire is directly connected to the voice coil indirectly through the electrical connection terminal, which prevents the externally connected connection wire from being directly pulled by external force to affect the vibration of the voice coil and the drum paper, thereby improving the sound quality of the speaker.

[0040] In the coaxial mid-high frequency speaker 1 system of the utility model, the connecting substrate 2 and the tweeter horn 10 are made of a plastic material to form an integral part. The plastic material has the characteristics of electrical insulation, lightness, low cost and easy processing. The electrical insulation prevents the tweeter electrode seat 44 and the mid-range electrode seat 55 from short-circuiting. The connecting substrate 2 and the tweeter horn 10 are made of a plastic material to form an integral part, which further simplifies the production process, reduces the assembly cost and time, and also improves the stability and durability of the structure. The integrally formed connecting substrate 2 and tweeter horn 10 provide better mechanical stability, reduce structural deformation caused by vibration, and ensure the performance of the speaker at high power output. The plastic material has a certain waterproof performance, which can provide additional protection for the speaker system, especially when used in a humid environment. The plastic integral part can easily realize complex geometric shapes and smooth surface treatment, which helps to improve the appearance quality of the product and meet the requirements of modern consumers for product aesthetics. The processing flexibility of plastic materials allows designers to create more innovative shapes and structures to adapt to different application requirements and aesthetic preferences. Plastic materials can be easily recycled, which helps to reduce environmental impact and meets the pursuit of environmentally friendly products in modern society. Plastic materials have good insulation properties, which help protect electrical components, reduce electromagnetic interference, and improve the safety and reliability of speaker systems. Compared with metal or other materials, plastics have lower manufacturing costs, which helps reduce the production cost of the entire speaker system and improve market competitiveness. High-quality plastic materials have good anti-aging properties and can maintain stable physical and acoustic properties during long-term use. Plastic materials can achieve a variety of colors and appearance effects through coloring or coating processes, providing more diverse design options for products.

[0041] The connecting substrate 2 of the utility model is extended with three connecting arms 21, and the connecting arms 21 are used to connect and fix the tweeter 1 and the woofer. The connecting arm 21 is provided with two assembly holes 22, the first assembly hole is used to fix and connect the tweeter 1, and the other assembly hole is used to fix and connect the midrange speaker 3. In the coaxial mid-high speaker 1 system of the utility model, the connecting substrate 2 realizes the stable fixation and connection of the tweeter 1 and the midrange speaker 3 through the three extending connecting arms 21. The setting of the connecting arm 21 provides a more stable support for the tweeter 1 and the midrange speaker 3. Through the two assembly holes on the connecting arm 21, the tweeter 1 and the midrange speaker 3 can be fixed respectively to ensure their stability and synchronization during operation. Through the two assembly holes, the tweeter 1 and the midrange speaker 3 are firmly connected together, which improves the stability of the structure of the utility model, so that the speaker assembly can be kept stable and the sound distortion can be reduced in the case of high volume output or external vibration. The design of the three connecting arms 21 simplifies the installation process of the tweeter 1 and the midrange speaker 3. The installer can easily fix them through the assembly holes, which improves the assembly efficiency. The design allows the speaker system to be more easily adapted to tweeters and midrange speakers 3 of different models and sizes, increasing the versatility and flexibility of the product. Through precise fixing and connection, the connecting arm 21 helps optimize the acoustic performance of the speaker and provide clearer and more balanced sound quality. The design of the connecting arm 21 can also take into account the appearance of the product, forming a harmonious whole with the connecting substrate 2 and the speaker assembly, and enhancing the visual appeal of the product.
