[0023] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0024] The terms “first”, “second”, etc. used in this document do not specifically refer to an order or sequence, nor are they used to limit this application. They are merely used to distinguish components or operations described with the same technical terms.

[0025] See also Figure 1 This is a schematic diagram of an ambient light music glass with a sound cavity structure using a light guide plate as a diaphragm, according to one embodiment of the present application. As shown, the ambient light music glass 1 with a sound cavity structure using a light guide plate as a diaphragm includes a window assembly 2, a light guide plate 3, a light and audio linkage control module 4, an audio driver module 5, multiple ambient light assemblies 6, and a spacer assembly (not shown). In this embodiment, the window assembly 2 refers to a window on a car, rail transit, subway, or the like. The window assembly 2 includes a transparent region 21 and a non-transparent region 22 surrounding the transparent region 21.

[0026] Please also refer to Figure 2 , which is a schematic diagram of a light guide plate provided on a window assembly according to an embodiment of the present application; as shown in the figure, the light guide plate 3 is provided on the window assembly 2. Part of the light guide plate 3 is located in the transparent area 21 of the window assembly 2, and the other part of the light guide plate 3 is located in the non-transparent area 22 of the window assembly 2. Preferably, the size of the light guide plate 3 located in the transparent area 21 of the window assembly 2 is 2-10 cm, but not limited to this. The outer layer of the light guide plate 3 is a diaphragm, and the interior of the light guide plate 3 is a sealed hollow structure, forming a first sound cavity 301 for transmitting full-band audio.

[0027] Specifically, the light guide plate 3 is designed to have a mutually fusionable structure based on the structure of the window assembly 2. In other words, the light guide plate 3 is mainly fused with the non-transparent area 22 of the window assembly 2. The inner size of the light guide plate 3 exceeds the edge of the transparent area 21 by 2-10 cm. The structure of the light guide plate 3 is similar to an ultra-thin, fully sealed hollow structure to facilitate audio transmission.

[0028] The spacer assembly is arranged between the window assembly 2 and the light guide plate 3. The spacer assembly separates the light guide plate 3 and the window assembly 2 into another sealed hollow structure, forming a second sound cavity 302 for enhancing high-frequency transmission. In this embodiment, the spacer assembly includes a spacer and an adhesive. The adhesive bonds the outer edge of the light guide plate 3 to the window assembly 2, and the adhesive is preferably an acrylic adhesive. The spacer is arranged in the non-transparent area 22 and is located on the inner side of the adhesive. The spacer is preferably made of acrylic material. The light guide plate 3 is arranged on the spacer. Another sealed hollow structure is formed between the light guide plate 3, the spacer, the adhesive and the window assembly 2.

[0029] Specifically, at the edges of the non-transparent area 22 and the transparent area 21 of the light guide plate 3 and the window assembly 2, that is, the range covered by the entire light guide plate 3, a layer of chemical liquid is applied on the edge of the window assembly 2, and the chemical liquid needs to be air-dried at room temperature. After air-drying, a layer of ultra-thin acrylic material is added on the surface, and finally a layer of acrylic adhesive is applied to the edge of the light guide plate 3 to fit the light guide plate 3 and the window assembly, thereby forming a second sound cavity 302.

[0030] See also Figure 3 Also see Figure 1 , Figure 3 This is a partial schematic diagram of an ambient light music glass with a sound cavity structure using a light guide plate as a diaphragm, according to an embodiment of the present application. As shown, the audio driver module 5 is connected to the light guide plate 3 and is used to drive the diaphragm to produce sound. When the audio driver module 5 drives the diaphragm to produce sound, the first sound cavity 301 transmits full-band audio, and the second sound cavity 302 enhances high-frequency transmission. The first sound cavity 301 and the second sound cavity 302 form a dual sound cavity, which can ensure improved sound quality, create a strong low-frequency shock and super strong directionality, and fully demonstrate the advantages of surface sound. In this embodiment, the audio driver module 5 includes multiple driving components (not shown) and multiple resonance absorption layers (not shown). Each driving component is arranged in the non-transparent area 22 through the resonance absorption layer and is connected to the light guide plate 3. The driving components include linear motors, piezoelectric ceramics, or actuators.

[0031] Specifically, the audio driver module 5 is located at the edge of the light guide plate 3. Using acoustic simulation technology, driver components are placed on the surface of the light guide plate 3 to create surface sound generation. A resonance absorption layer is placed between the driver components and the glass to absorb excess resonance forces, thereby extending the lifespan of the light guide plate 3. Furthermore, the driver component electrode terminals are connected to an ultra-thin cathode electrolyte layer. By varying the connection method, multiple independent driver modules are formed. Each of these individual driver modules is ultimately driven uniformly, transforming the entire light guide plate 3 into a large diaphragm for audio transmission.

[0032] Refer back Figure 1 As shown, multiple ambient light components 6 are arranged on the window component 2 and are located at the edge of the light guide plate 3. Figure 4 , which is a decomposed schematic diagram of the atmosphere lamp assembly of an embodiment of the present application; as shown in the figure, the atmosphere lamp assembly 6 includes an atmosphere lamp 61 and a calcium carbonate layer 62. The atmosphere lamp 61 is arranged on the window assembly 2 through the calcium carbonate layer 62. In order to increase the visual effect, the light source of the atmosphere lamp 61 can be selected as a colorful lamp. In order to improve the reliability and safety of the product, the atmosphere lamp assembly 6 also includes a flame retardant coarse cloth base material 63, and the flame retardant coarse cloth base material 63 is arranged on the atmosphere lamp 61. The flame retardant coarse cloth base material 63 has the characteristics of high temperature resistance, aging resistance, softness and fit, good shape, easy punching, acid and alkali resistance, and poison resistance.

[0033] Specifically, a circle of ambient lights 61 is added to the edge of the light guide plate 3. The light source of the ambient lights 61 can be a colorful light to enhance the visual effect. A layer of calcium carbonate 62 is also added to the bottom of the ambient lights 61. The ambient lights 61 are evenly attached to the calcium carbonate layer 62. This lifts the ambient lights 61 up, lowering their temperature and protecting them from wear and tear caused by vibrations between them and the window components, thereby increasing their service life. Furthermore, a layer of flame-retardant coarse cloth-based material 63 is provided above the ambient lights 61. The flame-retardant coarse cloth-based material 63 completely covers the ambient lights 61 underneath, thereby improving the reliability and safety of the product.

[0034] The light-audio linkage control module 4 is electrically connected to the audio driver module 5 and the ambient light assembly 6. In this embodiment, the light-audio linkage control module 4 includes an amplification control module (not shown) and a master control module (not shown). The amplification control module is used to amplify the input micro-signal to a desired signal that has the same variation pattern as the original input signal. The master control module is equipped with an input interface, an amplifier output interface, a control interface, and a single-chip microcomputer circuit.

[0035] Specifically, the light audio linkage control module 4 refers to the connection of the audio signal amplification control module on the main control of the integrated control system, which amplifies the input WeChat signal to a signal that is consistent with the change law of the original input signal, that is, distortion-free amplification. The main control module is provided with an input interface, an amplifier output interface and a control interface. Among them, the input interface is set to 4 channels to meet the audio input of 4 different parameter requirements. The 4-channel input interface includes a Bluetooth audio input interface, an ordinary standard AUX audio input interface, an audio input interface matching the 5W 8-ohm amplifier audio output interface, and a differential audio input interface. The 4-channel input interface is a 4-choose-1 interface, that is, only 1 of them is working at the same time; the amplifier output interface has an output impedance dynamic adjustment function to match speaker loads with different impedances.

[0036] In addition, the main control module is equipped with a single-chip microcomputer circuit to collect audio signal changes in real time and convert them into serial communication data. This data is used to interact with the control system of the ambient light 61, so that the lighting of the ambient light 61 can display different display effects according to the changes in the audio signal. It also has the function of real-time sampling of output voltage and current. It can meet two functions simultaneously: the first is that the audio driver module 5 and the ambient light component 6 operate simultaneously, and the second is that the audio driver module 5 operates alone and the ambient light component 6 does not operate.

[0037] In one embodiment, the acoustic cavity structure of the ambient light music glass 1, which utilizes a light guide plate as a diaphragm, also includes a light guide plate dot design. Specifically, a dot pattern is provided on the side of the light guide plate 3 facing away from the ambient light assembly 6. This dot pattern enhances the creativity and brightness of the ambient light 61. The dot pattern is introduced onto the light guide plate 3 using a special chemical liquid and ultra-high-precision printing technology. When the ambient light assembly 6 illuminates, the light projects the dot pattern onto the transparent area 21, enhancing the visual experience while also increasing its brightness. Furthermore, the dots are transparent in sunlight, but the designed dot pattern is visible when illuminated.

[0038] When the sound cavity structure atmosphere light music glass 1 with a light guide plate as a diaphragm of this embodiment is applied to a car sunroof, the window assembly 2 is selected as a car sunroof, and the size of the light guide plate 3 is determined according to the transparent area of ​​the car sunroof (note that the light guide plate 3 here is in a transparent state), and its overall size exceeds the transparent area of ​​the sunroof glass by 2-10cm. The light guide plate 3 is then designed to be an ultra-thin hollow structure, and then the audio driving module 5 is placed in the edge area of ​​the light guide plate 3 using a unique sound field simulation technology.

[0039] Next, a layer of chemical liquid is applied to the edge of the skylight area covered by the light guide plate 3. This chemical liquid needs to be air-dried at room temperature. After drying, an ultra-thin layer of acrylic material (spacer) is added to the surface. The light guide plate 3 is symmetrically bonded to the transparent area of ​​the skylight to form a second sound cavity 302.

[0040] Finally, attach the ambient light assembly 6 to the edge of the light guide plate 3. Connect the leads from the ambient light 61 and the audio driver module 5 to the light-audio linkage module 7 for unified control of the product. The light-audio linkage module 7's output cable connects to the car's PC control unit, ultimately outputting two functions: the first, audio-controlled ambient light 61; the second, music-activated glass, which disables the ambient light 61.

[0041] The sound cavity structure atmosphere light music glass with a light guide plate as the diaphragm in this embodiment mainly provides an ultra-high reliability surface sound transparent car sunroof audio and atmosphere light integration. The application of the surface sound principle can ensure that the sound pressure in the area covered by the glass is almost the same, forming a Dolby effect, replacing the car speakers, not only satisfying the auditory experience, but also enhancing the visual experience. In addition, it can also improve the overall structure of the current car, reduce the weight of the car, and improve the space utilization of the car.

[0042] In summary, the present application provides an ambient light music glass with a sound cavity structure using a light guide plate as a diaphragm. The present application sets a light guide plate on the window assembly, and part of the light guide plate extends beyond the transparent area. The audio driver module is placed at the edge of the light guide plate using sound field simulation technology, and then the structure of the second sound cavity is designed to form a dual-cavity structure with the light guide plate body. The ambient light assembly is then installed and designed around the light guide plate, and finally the output leads of the two are connected to the light audio linkage control module to realize audio control of the ambient light lighting changes, presenting a new listening and visual enjoyment.

[0044] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
