Description

Technical Field

[0001] This invention relates to a musical glass, specifically to a linkage structure cavity that can enhance the SPL (Special Purpose Lift) of the 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. It is poised to replace traditional car stereos in the future, achieving thinner and lighter designs, and delivering a stunning new sound source experience and cutting-edge technology. However, due to the significant thickness of automotive glass components such as sunroofs and windshields, and their laminated structure, research has encountered a bottleneck: consistently low SPL values, making it difficult to increase sound pressure levels and further reduce overall power. Furthermore, as a large-area surface sound source, insufficient SPL can easily lead to increased THD, causing severe noise interference. Therefore, these issues urgently need to be addressed. Summary of the Invention

Detailed Implementation

[0023] The technical solution of the present invention will be clearly and completely described below through specific embodiments.

[0024] The present invention provides a linkage structure cavity for enhancing the SPL (Special Purity) of musical glass, comprising an active device 2, a microwave cavity 3, a linkage nano-cushion 4, and a metasurface crystal layer 5; the specific structure is as follows: Figures 1-3As shown, the active device 2 is attached to the original glass 1, and a metasurface crystal layer 5 is horizontally attached to the end face away from the original glass 1, thereby ensuring the stability of the sound wave transmission process through the metasurface crystal layer 5; wherein, the active device 2 is selected from linear motors, piezoelectric ceramics or exciters, thereby driving the original glass 1 to vibrate to achieve surface sound generation.

[0025] In this invention, a circular microwave cavity 3 is horizontally attached between the metasurface crystal layer 5 and the original glass 1, relative to the outer side of the active device 2. Figures 1-3 As shown, the microwave cavity 3 is spaced and sleeved on the active device 2, and together with the metasurface crystal layer 5 and the original glass 1, it forms a circular area, thereby enclosing the active device 2 within it; wherein, the coverage area of ​​the metasurface crystal layer 5 is larger than the coverage area of ​​the active device 2, and the size of the microwave cavity 3 matches the size of the metasurface crystal layer 5, thereby ensuring that it, the metasurface crystal layer 5, and the original glass 1 can form a circular area.

[0026] The microwave cavity 3 of this invention is made of a uniform silicone-like material, and several hexagonal holes 7 are evenly distributed and spaced along its circumferential direction on the outer circumferential surface of the microwave cavity 3, such as... Figures 1-3 As shown, each hexagonal hole 7 penetrates the inner circumference of the microwave cavity 3 perpendicularly, and the corresponding hexagonal holes 7 in adjacent columns are staggered at a certain angle, thereby ensuring the stability of airflow through the hexagonal holes 7; the size of each hexagonal hole 7 is determined according to the Q value and frequency of the loudspeaker, and the lower the frequency, the larger the size of a single hexagonal hole 7.

[0027] The upper surface of the microwave cavity 3 of this invention is a smooth and flat plane, and an acrylic adhesive layer is also provided on it, which is then bonded and connected to the metasurface crystal layer 5; for example Figures 1-3 As shown, the inner circumferential surface of the microwave cavity 3 is spaced apart from the active device 2, and a smooth and flat circular slot 8 is embedded through one side of the microwave cavity 3 at the position of the output end of the active device 2. The circular slot 8 is arranged without interfering with each hexagonal hole 7, and the lead wire 6 of the active device 2 is led out through the circular slot 8. A calcium carbonate sealing ring 9 matching the lead wire 6 is also coaxially sleeved in the circular slot 8. The size of the calcium carbonate sealing ring 9 matches the circular slot 8, and the lead wire 6 is sealed and fixed by the calcium carbonate sealing ring 9. The calcium carbonate sealing ring 9 used in this invention has excellent flame retardancy, high temperature resistance, low specific gravity, waterproof, shock absorption, sealing and heat insulation.

[0028] like Figures 1-3 As shown, a silicone film is also provided on the outermost edge of the microwave cavity 3 relative to the circular slot 8, thereby protecting the lead wire 6 from impact.

[0029] like Figures 1-3 As shown, the metasurface crystal layer 5 is a two-dimensional metacrystalline material constructed from a series of planar artificial atoms arranged in a specific manner, and its arrangement is determined according to the distribution of the hexagonal holes 7 in the microwave cavity 3. This makes the surface of the metasurface crystal layer 5 smooth and flat, with good light transmittance and conductivity. Through the precise design of artificial atoms at different positions in the plane, this invention can make the metasurface 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. In addition, compared with traditional three-dimensional metamaterials, the metasurface crystal layer 5 has advantages such as low loss, easy integration, and simple preparation process, so it can be used as the outermost layer of music glass.

[0030] In this invention, a linked nano-air cushion 4 is horizontally bonded between the metasurface crystal layer 5 and the active device 2. The linked nano-air cushion 4 and the microwave cavity 3 are configured to not interfere with each other, thereby forming a strongly coupled planar sound field through multi-dimensional integration with the microwave cavity 3 and the metasurface crystal layer 5, thus improving the SPL value of the musical glass. Figures 1-3 As shown, the linked nano-cushion 4 serves as a transition layer connecting the active device 2 and the metasurface crystal layer 5, and its size matches that of the active device 2. The linked nano-cushion 4 is made using a porous stacking technology, with its intermediate layer composed of stacked nanocavities 41. This not only provides cushioning and shock absorption but also ensures the transmission and transient stability of the acoustic wave pattern, enhancing SPL sensitivity and significantly improving high-frequency performance. A silicone layer 42 is deposited on the upper and lower surfaces of the nanocavities 41, and an acrylic adhesive 43 is applied to the outer surface of each silicone layer 42. The acrylic adhesive 43 is used for shaping and bonding, thus forming the linked nano-cushion 4. The linked nano-cushion 4 of this invention possesses excellent flame retardancy, high temperature resistance, low specific gravity, waterproofing, shock absorption, sealing, heat insulation, UV resistance, ozone resistance, and good resistance to compression deformation and creep.

[0031] When the present invention is working normally, the active driving device will drive the overall linkage structure cavity to move. Through the multi-dimensional combination of microwave cavity 3 and nano cavity 41, the SPL value of the music glass is improved, and the FR performance is indirectly improved, and the THD is improved. As a result, the sound quality is not only better, but the overall power is also reduced, making it more energy-saving and environmentally friendly.

[0032] The beneficial effects of this invention are:

Thus, the sound quality is not only better, but the overall power is also reduced, making it more energy-saving and environmentally friendly.
