SPECIFIC IMPLEMENTATIONS



[0019] The specific implementations of the present disclosure will be described below with reference to the drawings.

[0020] As shown in FIG. 1, the present disclosure provides a music glass with a superconducting diaphragm metasurface acoustic superconducting structure, including a superconducting diaphragm assembly integrated with multiple superconducting diaphragm modules. The superconducting diaphragm module includes inner metasurface crystal layer 1, drive layer 2, outer nanocavity structure 3, inner nanocavity structure 4, and an outer metasurface crystal layer.

[0021] The inner metasurface crystal layer 1 is fixed to an original glass. The original glass refers to a primary glass assembly for mounting the music glass, such as vehicle window glass. The outer metasurface crystal layer is located outside the inner metasurface crystal layer 1. The outer nanocavity structure 3 and the inner nanocavity structure 4 are disposed between the inner metasurface crystal layer 1 and the outer metasurface crystal layer to enclose a sound cavity assembly. The outer nanocavity structure 3 and the inner nanocavity structure 4 each are made of a porous material. Air enters the sound cavity assembly from the outer nanocavity structure 3 and exits from the inner nanocavity structure 4. The drive layer 2 is disposed in the sound cavity assembly to drive the inner metasurface crystal layer 1 to vibrate and generate an acoustic wave. The acoustic wave is transmitted to the original glass to cause a diaphragm vibration, thereby forming a surface sound field.

[0022] Specifically, two sides of the inner nanocavity structure 4 are fixed to the inner metasurface crystal layer 1 and the outer metasurface crystal layer through pressure-sensitive adhesive, respectively. Only an outer side of the outer nanocavity structure 3 is fixed to the outer metasurface crystal layer through pressure-sensitive adhesive.

[0023] The inner nanocavity structure 4 and the outer nanocavity structure 3 enhance air compression inside the sound cavity assembly through a forward-flow state of air movement. During operation, the outer nanocavity structure 3 and the outer metasurface crystal layer apply inward thrust to the sound cavity assembly by vibrating to compress air. The sound cavity assembly utilizes a flow-conforming cavity design to allow air to enter from the outer nanocavity structure 3 and exit from the inner nanocavity structure 4. The inner nanocavity structure 4 has a higher density than the outer nanocavity structure 3 to prevent air dispersion in the sound cavity assembly, thereby increasing air compression volume, ensuring enhanced low-frequency amplitude, and improving low-frequency performance and sensitivity.

[0024] Preferably, the sound cavity assembly enclosed by the outer nanocavity structure 3 and the inner nanocavity structure 4 has a symmetrical structure. Specifically, the symmetry is centered on directional lines approaching and departing from a center of the original glass, where the arrow direction in FIG. 1 indicates the direction toward the center of the original glass. The outer nanocavity structure 3 is disposed on a side relatively closer to the center of the original glass, and the inner nanocavity structure 4 is disposed on a side relatively farther from the center of the original glass.

[0025] In a specific embodiment, the direction approaching the center of the original glass is defined as a front side, and the direction departing from the center of the original glass is defined as a rear side. The outer nanocavity structure 3 includes multiple front outer nanocavities 31 arranged on the front side and two side outer nanocavities 32 respectively arranged on left and right sides. The inner nanocavity structure 4 includes multiple front inner nanocavities 41 arranged on the front side and rear inner nanocavity 42 arranged on the rear side. The multiple front outer nanocavities 31 are spaced apart. The multiple front inner nanocavities 41 are spaced apart and disposed at a rear side of gaps of the multiple front outer nanocavities 31. The rear inner nanocavity 42 is disposed at a rear side of the multiple front inner nanocavities 41. The two side outer nanocavities 32 are respectively arranged on the left and right sides, each forming an outwardly convex arc shape extending from the front outer nanocavities 31 to the rear inner nanocavity 42. The arc-shaped side outer nanocavities 32 have a minimum damping coefficient to further increase air compression volume in the sound cavity assembly.

[0026] Preferably, pores in the outer nanocavity structure 3 are nanopores. Numerous nanopores are densely packed in the outer nanocavity structure 3 and oriented at 35-45° relative to the inner metasurface crystal layer 1 to facilitate air entry into the sound cavity assembly. Pores in the inner nanocavity structure 4 are nanopores. Numerous nanopores are densely packed in the inner nanocavity structure 4 and oriented at 25-35° relative to the inner metasurface crystal layer 1 to hinder air exit from the sound cavity assembly.

[0027] The outer nanocavity structure 3 and the inner nanocavity structure 4 each are made of silicone. Silicone not only provides a porous structure but also exhibits excellent flame retardancy, high temperature resistance, low specific gravity, waterproof performance, vibration damping, sealing, heat insulation, ultraviolet (UV) resistance, ozone resistance, effective compression deformation resistance, and creep resistance.

[0028] The inner metasurface crystal layer 1 and the outer metasurface crystal layer each are made of a two-dimensional crystal material. Alternatively, the inner metasurface crystal layer 1 is a metal diaphragm with a three-dimensional cavity structure, and the outer metasurface crystal layer is a nano-metal layer.

[0029] The two-dimensional crystal material is constructed as a two-dimensional artificial crystalline metamaterial including a series of planar artificial atoms arranged in a specific configuration, featuring a smooth surface with exceptional optical transparency and conductivity. Precise design of artificial atoms at different planar positions enables the metasurface crystal layer to achieve arbitrary electromagnetic wave reflection/transmission phase distributions, thereby allowing free and efficient control of electromagnetic wavefronts. This ensures stable and reliable acoustic wave transmission with low loss. The two-dimensional crystal material may specifically be ultrathin transparent glass or an ultrathin opaque material made primarily from ceramics and silicon.

[0030] The metal diaphragm includes a nano-metal layer, a nano-alloy layer, a nanocavity structure layer, and a nano-alloy layer sequentially arranged. The nano-metal layer is located at an outermost side close to the original glass. The nano-metal layer is made of a metal with good thermal conductivity such as copper, gold, or silver for cooling. The nano-alloy layer is a two-dimensional crystal, such as sodium-magnesium-aluminum alloy. The nanocavity structure layer is a cavity structure formed by a nanomaterial arrangement and may specifically be silicone, thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), thermoplastic polyolefin (TPO), natural rubber, etc.

[0031] The metal diaphragm improves conductivity and reduces surface temperature through the nano-metal layer, and acoustic wave transmission exhibits no loss when contacting the nano-metal layer. The nanocavity structure layer not only reduces damping and weight but also connects the nano-alloy layers on both sides to ensure acoustic signal superposition. This effectively enhances low-frequency performance while preventing high-frequency attenuation.

[0032] As shown in FIG. 2, the drive layer 2 includes sound-generating component 21 in surface-emission form and pneumatic connection layer 22. The sound-generating component 21 is a linear motor, piezoelectric ceramic, or actuator. The sound-generating component 21 provides an audio source and directly applies force to the inner metasurface crystal layer 1. The pneumatic connection layer 22 is made of a nano-porous material, which may specifically be ethyl vinyl acetate (EVA), polyethylene (PE), chloroprene rubber (CR), polyurethane (PU) foam, PORON, vibration-damping paper, composite pearl cotton, expanded polypropylene (EPP), etc., but is not limited to solid damping materials such as rubber, silicone, or air cushions. The sound-generating component 21 is fixed to the inner metasurface crystal layer 1 through the pneumatic connection layer 22. Specifically, a surface of the pneumatic connection layer 22 is coated with pressure-sensitive adhesive, with one side contacting the sound-generating component 21 and the other side contacting the inner metasurface crystal layer 1. Nano-pores in the pneumatic connection layer 22 optimize force transmission of the sound-generating component 21 while serving as a buffer between the sound-generating component 21 and the inner metasurface crystal layer 1 to reduce vibration amplitude. A lead of the sound-generating component 21 passes through the front outer nanocavity 31.

[0033] As shown in FIG.3, the superconducting diaphragm module further includes a conduction structure. The conduction structure includes composite ultrasonic conduction layer 51 and bonding layers 52 bonded to two side surfaces of the composite ultrasonic conduction layer.

[0034] The composite ultrasonic conduction layer 51 is a magnetic structure made of a rare-earth permanent magnetic material. The composite ultrasonic conduction layer 51 generates a magnetic field to enhance driving thrust for the sound-generating component 21. Specifically, the composite ultrasonic conduction layer 51 is compressed into a required structural form by processing the rare-earth permanent magnetic material into powder and applying a technical treatment. The composite ultrasonic conduction layer 51 acquires ultra-strong magnetism through magnetic processing to ensure a strong surrounding magnetic field, which synergizes with the sound-generating component 21 for magnetic superposition. When the sound-generating component 21 operates, additional driving thrust is provided, enabling the sound-generating component 21 to generate great vibration amplitude with low voltage, thereby significantly extending the lifespan of the sound-generating component 21. A layer of black ink is coated on the surface of the composite ultrasonic conduction layer 51 and undergoes smoothing and high-temperature treatment. This black coating exhibits excellent resistance to high/low temperatures and corrosion. The bonding layer 52 is pressure-sensitive adhesive.

[0035] The composite ultrasonic conduction layer 51 is fixed between the inner metasurface crystal layer 1 and the original glass A through the bonding layers 52. Specifically, the bonding layer 52 is further fixed to the inner metasurface crystal layer 1 and the original glass A through acrylic adhesive 53: The bonding layer 52 and the center of the inner metasurface crystal layer 1 are bonded via the acrylic adhesive 53. The bonding layer 52 assembly and the original glass A are bonded via the acrylic adhesive 53 on both sides.

[0036] Integration of the superconducting diaphragm modules refers to multiple superconducting diaphragm modules being integrated onto the same original glass. The quantity of the integrated superconducting diaphragm modules depends on the dimensions, thickness, curvature, and structure of the original glass. Specifically, multiple superconducting diaphragm modules are determined according to the glass vibration amplitude uniformity principle to ensure overall sound field homogeneity.

[0037] The music glass further includes an audio decoding chip and a control power amplification module. The sound-generating components 21 of the multiple superconducting diaphragm modules are electrically connected to the audio decoding chip and the control power amplification module, forming a current-dominant circuit module. This circuit module primarily uses current as the key parameter for controlling, processing, and transmitting signals.

[0038] Specifically, the audio decoding chip and the control power amplification module are formed by an integrated printed circuit board assembly (PCBA) and an external control box. The PCBA includes the audio decoding chip to facilitate various audio inputs while providing filtering, power amplification, and overload protection functions.

[0039] The music glass possesses output current and output voltage protection functions. When the output current reaches a maximum allowable value or the output voltage exceeds a peak voltage, the music glass automatically limits the output voltage or current by adjusting the audio input voltage. This ensures operation within maximum allowable limits of voltage and current to protect a control board and a music glass load. The music glass also features real-time monitoring of output current and output voltage. The resistance of the connected load is calculated via output voltage and current values, and open/short-circuit faults are determined based on resistance magnitude. The music glass further includes equalizer (EQ) voltage (abbreviated as sound effects) software import functionality with an audio range of 20 Hz to 20 kHz.

[0040] The present disclosure enables the music glass to replace an in-vehicle audio system for in-vehicle stereo sound. Specifically, the superconducting diaphragm assemblies are disposed on a front windshield, a sunroof, and a rear windshield of a vehicle, forming a left channel, a right channel, and a left channel in sequence, or forming a right channel, a left channel, and a right channel in sequence to achieve front-row and rear-row left-right stereo sound. The front-row stereo sound is realized via the superconducting diaphragm assemblies on the front windshield and the sunroof, while the rear-row stereo sound is achieved via the superconducting diaphragm assemblies on the sunroof and the rear windshield.

[0041] In the present disclosure, unless otherwise specified, the scientific and technical terms used herein have the meanings commonly understood by those skilled in the art.

[0042] It should be noted that, as used herein, terms such as "upper", "lower", "left", "right", "front" and "back" are merely employed for ease of a description, and not intended to limit the implementable scope of the present disclosure, and a change or adjustment of its relative relation shall also be deemed as falling within the implementable scope of the present disclosure without a substantial alteration of a technical content.
