Description

Technical Field

[0001] This invention relates to the field of musical glass technology, and in particular to a hollow magnetic conductor structure based on musical glass. Background Technology

[0002] Music glass is a new type of professional audio product that can be integrated into any automotive glass, providing customers with a large-area, highly directive, highly reliable, and simplified tuning experience, offering top-down, left-to-right, and front-to-back listening sensations. Furthermore, the increasing number of in-car speakers is driving up tuning costs. Music glass, using the car glass as a sound source carrier, will simplify tuning, eventually becoming obsolete; it will inevitably replace car stereos in the future, achieving the goals of thinner, lighter, and more immersive sound experiences and cutting-edge technology. However, music glass creates a large-area surface sound field. As the sound pressure level exceeds 95dB, not only does the sound pressure level on the outer edges increase, but the resonance noise and harmonic distortion generated by the glass also become more pronounced.

[0003] Given this situation, there is an urgent need to invent a hollow magnetic conductor structure based on music glass, which solves the problems of increased sound pressure, resulting in noise, harmonic distortion, and increased external sound pressure. At the same time, it improves fidelity, provides a brand-new Hi-Fi effect, better meets the needs of new energy vehicles for low power consumption, thinning, and weight reduction, presents a brand-new audio experience, and gives car audio a brand-new shock effect. Summary of the Invention

[0004] The purpose of this invention is to provide a hollow magnetic conductor structure based on musical glass, which ensures that the amplitude at the resonance point can be reduced during high sound pressure operation. While reducing displacement, the sound pressure is not affected, thereby improving fidelity and sound quality.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A hollow magnetic conductor structure based on music glass includes a lower metasurface crystal layer, which serves as the main diaphragm of the sound source glass. An active driving element is disposed on the lower metasurface crystal layer, which drives the entire lower metasurface crystal layer to move. A magnetic conductor is attached to the lower metasurface crystal layer, and a magnetic cavity structure is also disposed on the lower metasurface crystal layer. A nano-superconducting layer is disposed on the magnetic cavity structure, and an upper surface crystal layer is disposed on the other side of the nano-superconducting layer.

[0007] Furthermore, the magnetic cavity structure is designed based on the size of the lower metasurface crystal layer, avoiding the portion of the lower metasurface crystal layer with magnetic material at its bottom.

[0008] Furthermore, the magnetic cavity structure includes two "I"-shaped structures that are separated from each other and parallel, and staggered vertically to form upper and lower gas flow holes.

[0009] Furthermore, the magnetic cavity structure and the lower metasurface crystal layer are fixed together by an acrylic adhesive structure.

[0010] Furthermore, the acrylic adhesive structure comprises an acrylic liquid.

[0011] Furthermore, in the upper part of the "I" shaped structure, the acrylic liquid at the junction is designed as dots, while the acrylic liquid along the long side is designed as strips, and the lower part is symmetrically arranged with the upper part, and the inner and outer sides are symmetrically arranged.

[0012] Furthermore, the acrylic liquid is cured by irradiation with a light source.

[0013] Furthermore, the nano-superconducting layer is made of a uniform silicone-based material with a silicone layer deposited on its surface.

[0014] Furthermore, the outer side of the upper surface crystalline layer is coated with a layer of black ink.

[0015] This invention also discloses a method for manufacturing a hollow magnetic conductor structure based on musical glass, comprising the following steps: First, the driving components are bonded to the lower supersurface crystal layer. Based on the overall structure of the active driving components, the position and size of the magnetic cavity are determined on both sides of the driving components or at both ends of the lower supersurface crystal layer. On the contact surface between the magnetic conductor and the lower supersurface crystal layer, the bonding layer is fabricated. According to the magnetic cavity structure, the magnetic conductor is bonded to the lower supersurface crystal layer and connected to the magnetic cavity structure. Secondly, using acrylic liquid, the magnetic cavity structure is bonded to the lower metasurface crystal layer; after completing the acrylic bonding structure, the acrylic liquid is cured by irradiation with a light source; double bonding and curing ensures that the structure is firm and stable; Finally, the nano-superconducting layer is bonded to the magnetic cavity structure, and the other end is bonded to the upper surface crystal layer, wherein the nano-superconducting layer is bonded to the non-ink surface of the upper surface crystal layer.

[0016] In summary, the present invention has the following beneficial effects: It can be widely applied to planar and curved surface sound generation technology and integrated into music glass. It is mainly used in car sunroofs, windshields, etc. It solves the problem that when the sound pressure is >95dB, not only does the sound pressure on the outside increase, but also the resonance noise and harmonic distortion generated by the glass. In addition, it is also an invention for solving resonance noise and harmonic distortion in large-area glass. It is another improvement and discovery of glass diaphragm technology, and an innovative structure that rapidly improves performance indicators. Its value to music glass is immeasurable.

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0020] A hollow magnetic conductor structure based on musical glass can be widely used in glass components such as sunroofs and windshields of rail transit vehicles. Figure 1 and Figure 2 As shown, it includes a lower supersurface crystal layer 1, which is the main diaphragm of the sound source glass. An active driving element (such as a linear motor, piezoelectric ceramic, or exciter) is provided on the lower supersurface crystal layer 1. The active driving element drives the entire lower supersurface crystal layer 1 to move and produce sound. A bonding layer 2 is also provided on the lower supersurface crystal layer 1, and a magnetic conductor 3 is bonded to it through the bonding layer 2. A magnetic cavity structure 4 is also connected to the lower supersurface crystal layer 1. A nano-superconducting layer 6 is provided on the magnetic cavity structure 4, and the other end of the nano-superconducting layer 6 is connected to the upper surface crystal layer 7. In this embodiment, the magnetic cavity structure 4 and the lower supersurface crystal layer 1 are fixed together by an acrylic adhesive structure 5, and the upper side of the magnetic conductor 3 is connected to the upper surface crystal layer 7. The magnetic conductor 3 and the magnetic cavity structure 4 are symmetrically arranged, while the active driving component is located in the middle.

[0021] like Figure 2 As shown, the lower metasurface crystal layer 1 is a two-dimensional metacrystalline material constructed from a series of planar artificial atoms arranged in a specific manner. Used as the main diaphragm, its surface is smooth and flat, with good light transmittance and conductivity. Through precise design of the artificial atoms at different positions within the plane, the metasurface can have arbitrary electromagnetic wave reflection / transmission phase distribution, thereby achieving free and efficient control of the electromagnetic wave wavefront, ensuring stable and reliable sound wave transmission with low loss. Secondly, the lower metasurface crystal layer 1 serves as the main diaphragm of the sound source glass. Its surface integrates driving components and many microcavities, and its surface is transparent, making it easy to process and inspect. In addition, compared with traditional three-dimensional metamaterials, the metasurface crystal layer has advantages such as low loss, easy integration, and simple preparation process.

[0022] like Figure 2 As shown, the bonding layer 2 is a pressure-sensitive adhesive that is directly bonded to the lower supersurface crystal layer 1. Its thickness is very thin, on the micrometer scale. Its main function is to bond and fix the magnetic conductor 3 to the lower supersurface crystal layer 1, serving as a buffer and vibration damping agent. The bonding layer 2 has many advantages, such as excellent wide temperature range; excellent electrical properties and good leakage resistance; uniform water resistance, temperature resistance and weather resistance; and the ability to bond various difficult-to-bond low surface energy materials.

[0023] like Figure 2 and Figure 3 As shown, magnetic conductor 3 refers to a brand-new rare earth permanent magnet material, which is processed into powder, compressed into the required structural shape through processing, and then smoothed on the surface. Secondly, the magnetic conductor 3 is magnetized according to the resonant frequency generated by the operation of the lower metasurface crystal layer 1 to achieve a certain magnetic flux, thereby giving the magnetic conductor 3 permanent magnetism. Under the action of its magnetic field, it is blocked from propagating in a certain frequency range, while it can propagate without loss in other frequency ranges, playing a vibration reduction role to ensure stability during sound wave transmission.

[0024] like Figure 3 As shown, the magnetic cavity structure 4 refers to the structure designed according to the magnitude of the vibration using a magnetic conductor material to form the final magnetic cavity, thereby increasing the magnetic field and acting on the lower metasurface crystal layer 1 to enhance the sound wave. The magnetic cavity structure 4 is designed based on the size of the lower metasurface crystal layer 1 and is directly fixed on the lower metasurface crystal layer 1, but avoids the part with magnetic material at the bottom of the lower crystal layer, and the size of its upper edge is smaller than the size of the upper edge of the bottom magnetic material. The magnetic cavity structure 4 is divided into upper and lower parts. The upper part is shaped like an "I" and is parallel to the short side crystal layer. The lower part is the same as the upper part, and the two are separated and parallel to each other. The two are staggered and combine to form upper and lower gas flow holes, which act on both sides of the lower metasurface crystal layer 1.

[0025] like Figure 4As shown, the acrylic adhesive structure 5 refers to the use of an acrylic liquid to fix the magnetic cavity structure 4 and the lower metasurface crystal layer 1. First, at the junction of the upper part of the "I" shape, the acrylic liquid is designed as dots, and the lower part is the same as the upper part; second, in the upper and lower parts along its long side, the acrylic liquid is designed as strips, and the inner and outer sides are symmetrical. Finally, the acrylic liquid is cured by irradiation with a light source, and a secondary fixation process is performed to ensure that the magnetic cavity structure 4 is firmly fixed to the lower metasurface crystal layer 1.

[0026] like Figure 2 As shown, the nano-superconducting layer 6 is the intermediate layer between the magnetic cavity structure 4 and the upper surface crystal layer 7, transmitting the acoustic signals of both. Through the nano-cavity inside the nano-superconducting layer 6, air circulation is ensured and the airflow is increased; at the same time, its material properties are used to reduce vibration and reduce motion displacement, effectively ensuring the stability of the overall structure and solving the harmonic distortion caused by resonance. Secondly, the nano-superconducting layer 6 uses a novel, uniform silicone-based material with a dense nanoporous design arranged in an orderly manner. A silicone layer is deposited on the surface, and on the surface of the silicone layer is a novel pressure-sensitive adhesive system, ensuring a smooth surface, high hardness, and easy shaping and bonding.

[0027] like Figure 2 As shown, the nano-superconducting layer 6 is placed on the magnetic cavity structure 4, and its adhesive layer is directly attached to the magnetic cavity structure 4. The size of the nano-superconducting layer 6 is slightly larger than that of the magnetic cavity structure 4 to achieve complete coverage, leaving only the upper and lower pores of the magnetic cavity structure. The nano-superconducting layer 6 is in direct contact with the upper surface crystal layer 7, and the bonding is bubble-free; In addition, the Linkage Nano Air Cushion (nano superconducting layer 6) has excellent flame retardancy, high temperature resistance, low specific gravity, waterproof, shock absorption, sealing, heat insulation, UV resistance, ozone resistance, good resistance to compression deformation and creep resistance.

[0028] The upper surface crystal layer 7 is a two-dimensional metacrystalline material constructed from a series of planar artificial atoms arranged in a specific manner, used as an auxiliary diaphragm; its surface is smooth and flat, with good light transmittance and conductivity. Through the precise design of artificial atoms at different positions in the plane, the metasurface can have arbitrary electromagnetic wave reflection / transmission phase distribution, thereby achieving free and efficient control of the electromagnetic wave wavefront, ensuring stable and reliable sound wave transmission with low loss; Secondly, the difference between the upper surface crystal layer 7 and the lower supersurface crystal layer 1 is that the outermost layer of the upper surface crystal layer 7 is coated with a layer of black ink and subjected to high temperature treatment, resulting in a smooth and flat surface with a certain protective function; the internal structure cannot be seen from the outside, which contributes to the aesthetics of the process.

[0029] This embodiment also discloses a method for manufacturing a hollow structure of a magnetic conductor 3 based on music glass. First, the driving components are bonded to the lower metasurface crystal layer 1. Based on the overall structure of the active driving components, the position and size of the magnetic cavity are determined on both sides of the driving components or at both ends of the lower metasurface crystal layer 1. A bonding layer 2 is fabricated on the contact surface between the magnetic conductor and the lower metasurface crystal layer 1. The magnetic conductor 3 is bonded to the lower metasurface crystal layer 1 according to the magnetic cavity structure 4, and the magnetic cavity structure 4 is connected.

[0030] Secondly, using acrylic liquid, the magnetic cavity structure 4 is bonded to the lower metasurface crystal layer 1; after completing the acrylic bonding structure 5, the acrylic liquid is cured by irradiation with a light source; double bonding and curing ensure that the structure is firm and stable.

[0031] Finally, the nano-superconducting layer 6 is bonded to the magnetic cavity structure 4, and the other end is bonded to the upper surface crystal layer 7 (Note: the nano-superconducting layer 6 is bonded to the non-ink side of the upper surface crystal layer 7), ensuring that the planar bonding is completed without air bubbles.

[0032] Working principle: During normal operation, the active driving components drive the movement of the lower metasurface crystal layer 1. The sound wave is transmitted to the magnetic conductor 3 through the lower metasurface crystal layer 1, ensuring that the sound wave is lossless. The magnetic conductor 3 then passes through the magnetic cavity structure 4 to increase airflow, which enhances the sound wave. The sound wave is then processed by the nano-superconducting layer 6 to reduce the resonance at the point of resonance, while the rest remains unchanged. The finally processed sound wave is transmitted to the upper surface crystal layer 7, which further enhances the sound wave. This hollow structure of the magnetic cavity ensures that the amplitude at the resonance point can be reduced during high sound pressure operation, and the displacement is reduced without affecting the sound pressure; its fidelity is improved and the sound quality is better.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection. Such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present invention.
