[0021] To make the objectives, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0022] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic diagram of the transparent speaker with reliable metal in the first embodiment of the present application. Figure 2 Another schematic diagram of the transparent speaker with reliable metal in the first embodiment of the present application. As shown in the figure, the transparent speaker 1 with reliable metal includes a dielectric plane 2, a plurality of sound source components 3, a reliable metal structure 4, a speaker cover 5 and an adhesive structure layer 6. The reliable metal structure 4 is arranged around the dielectric plane 2, and the speaker cover 5 is arranged on the reliable metal structure 4. A hollow sound cavity is formed among the speaker cover 5, the dielectric plane 2 and the reliable metal structure 4. The dielectric plane 2 is made of glass, a PC board or an acrylic board, but is not limited thereto.

[0023] Refer to Figure 1 again. As shown, a plurality of sound source components 3 are arranged on the dielectric plane 2 and inside the reliable metal structure 4. The plurality of sound source components 3 and the dielectric plane 2 form a surface sound generation structure. In this way, the reliable metal structure 4 is applied to the surface sound generation transparent speaker, which can not only ensure the reliability of the transparent speaker, but also enhance the low-frequency sound quality. In this embodiment, a black ink area 201 is provided on the dielectric plane 2, and the plurality of sound source components 3 and the reliable metal structure 4 are located within the black ink area 201, but are not limited thereto.

[0024] Please refer to Figure 3 , which is a schematic diagram of the sound source component in the first embodiment of the present application. As shown in the figure, each sound source component 3 includes a planar buffer layer 31 and a sound generating component 32. The sound generating component 32 is arranged on the dielectric plane 2 through the planar buffer layer 31. The planar buffer layer 31 is the most important buffer layer between the sound generating component 31 and the vibration force generated by the dielectric plane 2, and plays a role in buffering and reducing the amplitude. The material of the planar buffer layer 31 is a solid damping material such as rubber, silica gel or air cushion, such as PE, CR, PU foam, PORON, adhesive non-woven fabric, flocking paper, and composite pearl cotton, EPP, etc. The sound generating component 32 mainly provides the sound source, and it can use a linear motor, a piezoelectric ceramic or an exciter, but is not limited thereto.

[0025] Refer back to Figure 1 As shown in Figure 2 The reliability metal structure 4 is a rectangular arc-shaped structure with a hollow interior. At the corresponding position between the reliability metal structure 4 and the sound source component 3, there is a V-shaped hole 41 to allow sound to enter. The interior of the metal is hollow, and the combination of the two enhances the sound quality effect in some frequency bands. In this embodiment, a molecular sieve 42 is provided inside the reliability metal structure 4 to ensure reliability requirements. When the sound source component 3 generates sound and propagates, this reliability metal structure 4 will generate a part of resonance displacement to improve the rock music experience effect.

[0026] Refer back to Figure 2 As shown in, the glue structure layer 6 is provided on the outer side of the reliability metal structure 4. The glue structure layer 6 is connected to the speaker cover 5, the dielectric plane 2, and the reliability metal structure 4, realizing the connection of the dielectric plane 2 with the reliability metal structure 4 and the speaker cover 5 together, enhancing the sealing effect of the hollow sound cavity. The glue structure layer 6 and the reliability metal structure 4 together ensure that the gas in the hollow sound cavity is not easily lost, and it has a dual moisture-proof and waterproof function.

[0027] The transparent speaker 1 with a reliability metal in this embodiment is mainly applicable to transparent display side windows of subways, urban rails, high-speed rails, cars, etc. The specific implementation steps are as follows: First, prepare the dielectric plane 2 with a black ink area 201, then sequentially bond multiple sound source components 3 on the dielectric plane 2, then bond the reliability metal structure 4 around the dielectric plane 2 while reserving a certain glue space, then place the speaker cover 5 on the reliability metal structure 4 to ensure its alignment with the dielectric plane 2, and finally apply glue to form the glue structure layer 6. In this way, the transparent speaker 1 can have extremely high sealing performance, not only with strong waterproof and moisture-proof capabilities, but also ensuring that the gas in the hollow sound cavity is not easily discharged, increasing the sound pressure. In addition, due to the frequency and design commonality of the metal, the enhanced low-frequency effect is more prominent, especially the sound of low-frequency musical instruments, which is applicable to percussion instruments, wind instruments, and plucked string instruments, with clear and transparent rhythm. It not only gives people a brand-new audio enjoyment in terms of hearing, but also a brand-new visual enjoyment.

[0028] In one embodiment, each sound source component 3 further includes a calcium carbonate material layer 34, and the calcium carbonate material layer 34 covers the periphery of part or all of the sound generating components 32 and the medium plane 2. The calcium carbonate material layer 34 means that the calcium carbonate material is selected according to the vibration amount to ensure that the calcium carbonate material fully covers the adhesive and the plane. The calcium carbonate material layer at least includes plastics, rubbers, coatings, ceiling panels, PVC, PE, paints or polyvinyl alcohol. This calcium carbonate material has unique strong adhesion, film flexibility, smoothness, oil and solvent resistance, protective colloid property, gas barrier property, abrasion resistance, temperature reduction property, etc. The calcium carbonate material layer 34 mainly functions to increase the impedance value, slow down the propagation of the vibration amount, and at the same time has strong shrinkage and temperature reduction functions, thereby solving the resonance distortion phenomenon caused by excessive sound pressure or large low-frequency amplitude in surface sound generation, and also solving the effect of reducing the temperature of the plane due to the increase in the rated power.

[0029] In one embodiment, referring back to Figure 3 As shown, each sound source component 3 further includes a sound absorption and vibration damping functional layer 33. The sound absorption and vibration damping functional layer 33 is disposed on the sound generating component 32. In addition, the inner top of the speaker cover 5 is closely combined with the sound absorption and vibration damping functional layer 33, and the two interact to generate a vertically downward pressure acting on the sound generating component 31, so that the sound generating component 31 can be closely attached, increasing the impedance of the sound generating component 31 and eliminating a part of the noise. The main materials of the sound absorption and vibration damping functional layer 33 include glass wool, extra-thick foam, nano tape, organic fiber materials, plywood, hard fiberboard, rubber pads or silicone pads.

[0030] In one embodiment, referring back to Figure 2 As shown, the transparent speaker 1 with reliable metal further includes a plurality of U-shaped structural members 7. The plurality of U-shaped structural members 7 are disposed on the medium plane 2. Each sound source component 3 is located within the corresponding U-shaped structural member 7. In other words, a circle of vibration damping material in the shape of a U is added around the sound source component 3, and its main purpose is to reduce the vibration amount while ensuring the uniformity of the sound field. The main materials of the U-shaped structural member 7 include rubber, silicone, EVA, PE, CR, PU foam or PORON, but are not limited thereto.

[0031] In summary, the present application provides a transparent speaker with reliable metal, which has extremely high sealing performance, not only has strong waterproof and moisture-proof properties, but also ensures that the gas in the hollow sound cavity is not easy to flow out to increase the sound pressure. In addition, due to the frequency and design commonality of the metal, the enhanced low-frequency effect is more prominent, especially the sound of low-frequency musical instruments, which is suitable for percussion instruments, wind instruments, plucked instruments, with clear and transparent rhythm. It not only gives people a brand-new audio enjoyment in terms of hearing, but also a brand-new visual enjoyment.
