Among them, as the core material on the outermost side of the product, there have always been problems with the physical and thermal properties of the surface. The temperature in the sound cavity is difficult to reduce and is fragile, and it remains unchanged when it reaches a certain hot spot. The sound quality of music glass increases due to the increase in temperature, causing an increase in electrical signal pulse interference, which not only causes a decline in sound quality but also causes a decrease in lifespan.

[0020] In order to elaborate on the technical scheme adopted by the present invention to achieve the predetermined technical purpose, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments, and the technical means or technical features in the embodiments of the present invention can be replaced without paying creative work. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses an acoustic superconducting structure of music glass. Figure 1 The acoustic superconducting structure of the music glass includes an inner superconducting diaphragm layer 1. In this embodiment, the inner superconducting diaphragm layer 1 is a superstructured crystal material constructed by a series of planar artificial atoms in a specific arrangement. Its surface is smooth and flat, and its physical, thermal and electrical properties are good. Through the precise design of artificial atoms at different positions in the plane, the superconducting diaphragm can have any electromagnetic wave reflection / transmission phase distribution, thereby realizing free and efficient regulation of the electromagnetic wave front, ensuring stable and reliable sound wave transmission with low loss; Secondly, the main material of the inner superconducting diaphragm layer 1 is aluminum nitride and aluminum oxide, and its thermal expansion coefficient is close to that of silicon chips, which reduces thermal resistance, reduces voids, has large current carrying capacity, can be diversified in size, and has high insulation withstand voltage. It has high efficiency in heat dissipation. During the operation of the product, in order to reduce the loss and weight of sound wave transmission, the superconducting diaphragm layer is designed to be very thin. By improving its density, bending strength and Vickers hardness, the problem of easy damage to the superconducting diaphragm layer is solved, and its durability is enhanced; In addition, the inner superconducting diaphragm layer 1 is used for the outermost layer of the music glass because it is easy to integrate and has a simple preparation process compared to traditional three-dimensional metamaterials. On the music glass, there will be multiple superconducting diaphragm layers of different structures and sizes to achieve the best sound field.

[0023] Reference Figure 1 A driving component 2 and an inner cavity structure 3 are provided on the inner superconducting diaphragm layer 1. The number of the driving components 2 is determined by calculating the sound field distribution of the superconducting diaphragm layer based on the acoustic simulation technology of the music glass. In this embodiment, the driving component 2 can be a piezoelectric ceramic driver, an electromagnetic driver or an electrostatic driver, etc.

[0024] Reference Figure 1 and Figure 2In this embodiment, two driving components 2 are respectively placed vertically on both sides of the inner superconducting diaphragm layer 1. At the same time, based on the principle of less sound field interference, another driving component 2 is placed in the central area. In addition, based on the fact that the driving components 2 at both ends are placed in the center and flush to reduce the loss of sound wave transmission, the central driving component 2 is tilted, and the corresponding tilt angle range of the driving component 2 is 30°-60°.

[0025] Reference Figure 1 and Figure 3 A microwave cavity 7 is designed under any driving component 2. The microwave cavities 7 are arranged in an orderly pattern at the bottom of the driving component 2. The microwave cavity 7 is attached to the two ends of the bottom of the driving component 2, and a gap is left in the middle. When the driving component 2 moves, the sound wave signal is transmitted, and the air inside and outside the cavity circulates and increases the air flow. The microwave design is used to ensure the double superposition of sound waves, and the SPL value is improved while changing the frequency.

[0026] Reference Figure 1 and Figure 3 In addition, the size of the single cavity is determined according to the Q value and frequency. The higher the frequency, the smaller the single cavity size, and the lower the frequency, the larger the single cavity size. The single cavity size of the microwave cavity 7 is determined. Therefore, a smaller cavity area is used in the design to divide the inner cavity into several small areas, which not only increases the strength of the cavity and reduces deformation, but also prevents mutual crosstalk between air and improves the noise problem.

[0027] Reference Figure 1 and Figure 4 An outer cavity structure 4 is provided at the edge of the inner superconducting diaphragm layer 1 , and the size of the outer cavity structure 4 covers the driving components 2 and the inner cavity structure 3 .

[0028] Reference Figure 1 and Figure 4 In this embodiment, the outer cavity structure 4 refers to a silicone material with fine and uniform pore size. According to the strength of the amplitude, a structure for solving the sound standing wave is designed at the edge of the inner superconducting diaphragm layer 1, and the interior is designed to be in the form of nano-circular holes inclined at 35°. These nano-circular holes form a dense shape. At the same time, nano-holes are opened on both sides of the outer cavity structure 4 to ensure that air passes through the gaps of the nano-cavity layer from the outer nano-cavity layer, and more regularly enters the hollow and sound cavity through the cavity processing holes of the outer cavity structure, and is also convenient for discharge from the other side. Secondly, the outer cavity structure 4 is thinner, which is more conducive to the flow and weight reduction of air, and will not cause an increase in the damping coefficient, thereby reducing performance.

[0029] Reference Figure 1 and Figure 4In this embodiment, the outer cavity structure 4 is designed according to the edge of the inner superconducting diaphragm layer 1, and the structures at both ends of the outer cavity structure 4 are designed to be symmetrical and consistent in size, and its size range covers the driving devices at both ends. The remaining area of ​​the outer cavity structure 4 is designed according to the size of the driving component 2, which is slightly larger than the corresponding driving component 2.

[0030] Reference Figure 1 and Figure 4 In this embodiment, the lead end of the driving component 2 is designed with an external cavity structure 4 to fully cover the driving component 2 structure, and the tail of the driving component 2 is designed with an internal cavity structure 3 to cover the gap of the external cavity structure 4. A certain gap needs to be reserved between the internal cavity structure 3 and the external cavity structure 4.

[0031] Reference Figure 1 and Figure 4 There are multiple inner cavity structures 3, and an inner cavity structure 3 with the same length as the component is placed in the middle of the gap between the two ends of the driving component 2 and the outer cavity structure 4. At the same time, the inner cavity structure 3 is placed on the side of the outer cavity structure 4 where the nanohole is opened. Under the action of the inner and outer cavity structures 4, the mass of the internal cavity is minimized and the air flow is maximized, which effectively improves the sensitivity of the music glass and reduces the problem of harmonic THD.

[0032] Reference Figure 1 and Figure 4 In this embodiment, the inner cavity structure 3 is mainly made of a silicone material with a higher specific gravity, fine and uniform pore size, and is supplemented by the outer cavity structure 4 to form a sealed cavity structure to enhance the internal cavity sound pressure and improve the SPL. The interior of the inner cavity structure 3 is designed to be a nano-circular hole shape inclined at 40°. These nano-circular holes are stacked in a dense shape. At the same time, nano-pores are also opened on both sides of the inner cavity structure 3. The aperture of the nano-pores in the inner cavity structure 3 is twice the aperture of the nano-pores in the outer cavity.

[0033] Reference Figure 1 and Figure 4 In addition, the inner and outer cavity structures 4 have the advantages of excellent flame retardancy, high temperature resistance, low specific gravity, waterproofness, shock absorption, sealing, heat insulation, UV resistance, ozone resistance, good resistance to compression deformation and creep resistance, etc.

[0034] Reference Figure 1 A conducting structure 5 is provided on the driving component 2, and an outer superconducting diaphragm layer 6 is provided on the side of the transmission structure away from the driving component 2. The outer superconducting diaphragm layer 6 has the same structure and material as the inner superconducting diaphragm layer 1, and is mainly used for the outermost side to serve as a sound cavity cover.

[0035] Reference Figure 1The conductive structure 5 is centrally arranged above the driving component 2. The conductive structure 5 is made of millimeter-level porous silicone material. The pores in the conductive structure 5 are arranged irregularly, which will drive the outer superconducting diaphragm layer 6 to vibrate slightly during movement. At the same time, the characteristics of the silicone material can play a role in buffering and shock absorption. The internal cavity structure utilizes airflow buffering and increases sound wave transmission to ensure that FR performance is improved and THD is reduced.

[0036] In the embodiment of the present application, an acoustic superconducting structure of music glass is provided. The structure is centered on a carefully designed inner superconducting diaphragm layer 1, which is constructed of planar artificial atoms with a specific arrangement, and can effectively regulate the wavefront of electromagnetic waves to ensure that the sound waves are stable and have low losses during transmission. The drive components 2 are integrated and arranged according to precise acoustic simulation results. These drive components 2 can excite the vibration of the inner superconducting diaphragm layer 1. The design of the microwave cavity 7 further enhances the double-layer superposition effect of the sound wave. By adjusting the cavity structure, the sound pressure level of the sound wave is effectively improved. At the same time, the inner , the outer cavity structure 4 is made of silicone material and is designed with inclined nanopores, which not only optimizes the flow of air, but also reduces the weight of the overall structure, while avoiding an increase in the damping coefficient; the conduction structure 5 is located between the driving component 2 and the outer superconducting diaphragm layer 6, and utilizes the pore characteristics of the silicone material to achieve a buffering and shock-absorbing effect, and enhance the transmission efficiency of sound waves; in summary, the acoustic superconducting structure of the music glass achieves efficient regulation and low-distortion transmission of sound waves through the coordinated work of this series of precisely designed components, thereby improving the sound quality performance of the music glass.

[0037] The present application also discloses a method for manufacturing an acoustic superconducting structure of music glass: S1. Sound field simulation based on internal superconducting diaphragm structure: Firstly, the structure of the inner superconducting diaphragm layer 1 is simulated and analyzed using advanced sound field simulation technology to determine the optimal design of the driver component 2, including the type, position, power and other parameters of the driver; S2, Structural design stage: Secondly, the outer cavity structure 4 and part of the inner cavity structure 3 are designed based on the structure of the inner superconducting diaphragm layer 1. The design of the outer cavity structure should take into account the propagation and reflection of sound waves, as well as the stability and aesthetics of the structure, while the design of the inner cavity structure focuses on the propagation efficiency of sound waves and the optimization of sound quality. S3, complete the lower part of the structure: According to the design requirements, the outer cavity structure 4 and part of the inner cavity structure 3 are gradually manufactured and assembled to ensure that the connection between the components is stable and reliable and meets the design requirements; S4. Design the remaining inner cavity structure 3: After the lower half structure is completed, the remaining inner cavity structure 3 is designed according to the characteristics and requirements of the outer superconducting diaphragm layer 6 structure to ensure that the inner cavity structure 3 can closely cooperate with the outer superconducting diaphragm layer 6 structure to jointly achieve the transmission of sound waves and the optimization of sound quality; S5, assembly and connection stage: After completing all structural designs, the outer superconducting diaphragm layer 6 structure is connected to the inner superconducting diaphragm layer 1 structure and other components using the conductive structure 5 design. The conductive design should ensure that sound waves can be efficiently transmitted between the components while maintaining the stability and reliability of the structure, ultimately forming a complete acoustic superconducting structure. At the same time, the number and location of the required acoustic superconducting structures can be determined based on the size of the sky curtain and the simulation results.
