For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0033] In the field of loudspeaker technology, loudspeakers with integrated lighting functions can create a sense of spatial atmosphere and enhance the user's immersive listening experience and visual interaction. However, these loudspeakers are usually quite large. In applications with smaller spaces, such as car audio systems, loudspeakers have been miniaturized. However, miniaturized loudspeakers often suffer from uneven light emission or visible LED residue on the diaphragm surface, affecting the visual effect and indicating room for improvement.

[0034] Therefore, this application proposes a loudspeaker 100, and the loudspeaker 100 according to an embodiment of the present disclosure is described below with reference to Figures 1-5.

[0035] As shown in Figures 1-5, a loudspeaker 100 according to an embodiment of the present disclosure includes: a loudspeaker body 10 and a light-emitting component 20. The loudspeaker body 10 includes a frame 11 and a diaphragm 12. The diaphragm 12 is disposed on the frame 11, and there is an installation space 101 between the diaphragm 12 and the frame 11. The light-emitting component 20 is disposed in the installation space 101. The light-emitting component 20 includes a light-emitting element 21 and a reflective element 22. The light-emitting element 21 is located on the side of the reflective element 22 closer to the diaphragm 12, and the light-emitting element 21 is adapted to emit light towards the side closer to the reflective element 22. The reflective element 22 can reflect the light emitted by the light-emitting element 21 towards the direction closer to the diaphragm 12.

[0036] Compared to the light-emitting element 21 emitting light directly towards the diaphragm 12, the speaker 100 of this embodiment can avoid problems such as the afterimage of the LED bead 212 on the surface of the diaphragm 12. It can also avoid the problem of uneven light output caused by the short optical path when the distance between the light-emitting element 21 and the diaphragm 12 is too small. In this embodiment, the light-emitting element 21 emits light away from the diaphragm 12 and then reflects the light to the diaphragm 12 through the reflector 22. This can increase the optical path between the light source and the diaphragm 12, improve the uniformity of brightness, and reduce visual fatigue such as glare caused by the light directly covering the diaphragm 12, thus improving visual comfort. Furthermore, by adjusting the positions of the light-emitting element 21 and the reflector 22, the optical effect can be optimized, and the size and shape of the light spot can be controlled to create a better atmosphere and enhance the visual appeal of the speaker 100.

[0037] According to the speaker 100 of this disclosure, by installing a light-emitting element 21 and a reflective element 22 in the mounting space 101, the light emitted by the light-emitting element 21 is reflected by the reflective element 22 to the diaphragm 12, thereby allowing the light to be reflected by the diaphragm 12 to the outside of the speaker 100. This integrates the light-emitting function into the speaker 100. Furthermore, since the light-emitting element 21 emits light away from the diaphragm 12 and then the light is reflected by the reflective element 22, the optical path between the light source and the diaphragm 12 can be increased, improving the uniformity of brightness. At the same time, it reduces visual fatigue such as glare caused by light directly covering the diaphragm 12, improves visual comfort, and enhances the user experience.

[0038] In the light-emitting component 20, the light-emitting element 21 can be an LED lamp bead 212, and the reflector 22 can be a reflector with high reflectivity. The light emitted by the light-emitting element 21 is reflected by the reflector 22 and then evenly illuminates the diaphragm 12, thereby avoiding the uneven light emission phenomenon caused by the light directly illuminating the diaphragm 12.

[0039] In some examples, the reflector 22 can be designed in an arc or other geometric shape to better control the direction and uniformity of light reflection. By rationally designing the shape and material of the reflector 22, the uniformity and brightness of light can be improved, the visual effect can be enhanced, and the user experience can be improved.

[0040] As shown in Figures 4 and 5, in some embodiments, the reflector 22 includes a diffuser 221 and a reflective layer 222. The reflective layer 222 is disposed on the side of the diffuser 221 away from the light-emitting element 21. The diffuser is used to diffuse the light emitted by the light-emitting element 21, and the reflective layer 222 is used to reflect the light in a direction close to the diaphragm 12.

[0041] The diffuser plate 221 diffuses the light emitted by the light-emitting element 21, making the light more uniform. The reflective layer 222 reflects the light towards the diaphragm 12, preventing the light from penetrating to the bottom of the speaker 100, and making the light emitted through the diaphragm 12 of the speaker 100 have higher energy.

[0042] The diffuser 221 can be made of a transparent or translucent material, such as polycarbonate or plexiglass. The reflective layer 222 can be made of a high-reflectivity material, such as aluminum foil or silver foil, and is coated on the side of the diffuser 221 opposite to the light-emitting element 21. Silicone particles can be used on the diffuser 221, uniformly distributed on its surface through spraying or impregnation processes to achieve uniform light diffusion. The reflective layer 222 can be coated using spraying or vacuum deposition processes to ensure its uniformity and high reflectivity.

[0043] As shown in Figures 4 and 5, in some embodiments, the angle between the normal at any point on the diffuser plate 221 and the center line of the diaphragm 12 is α, where 0°≤α≤15°.

[0044] That is, the normal at any point on the diffuser plate 221 is parallel to the center line of the diaphragm 12, or it can have a certain angle. The parallel arrangement allows the light diffused by the diffuser plate 221 to be directed toward the side where the diaphragm 12 is located. By limiting the angle, the light diffused by the diffuser plate 221 can be tilted toward the center of the diaphragm 12, thereby improving the uniformity of light output at the diaphragm 12.

[0045] By setting the angle between the normal on the diffuser plate 221 and the center line of the diaphragm 12 to α, where 0°≤α≤15°, it can be ensured that the light emitted by the light-emitting component 20 is evenly distributed on the surface of the diaphragm 12, thereby improving the uniformity of the light output effect at the diaphragm 12.

[0046] The angle α between the normal at any point on the diffuser plate 221 and the center line of the diaphragm 12 can be achieved through precision machining or mold forming. Specifically, the diffuser plate 221 can be made of a high-transmittance material, and during the manufacturing process, the microstructure or shape of its surface can be controlled to ensure that the angle between the normal at each point and the center line of the diaphragm 12 is within the range of 0° to 15°. For example, this angle can be achieved by setting tiny uneven structures on the diffuser plate 221 or by bending the diffuser plate 221 during the forming process. In addition, the choice of material for the diffuser plate 221 can also affect the light scattering effect; materials with high light transmittance and a certain degree of flexibility, such as plexiglass or polycarbonate, are preferred.

[0047] Therefore, this application can effectively improve the light emission effect of the miniaturized speaker 100. Compared with the prior art, this application, through the reasonable design of the geometry of the diffuser plate 221, enables the light emitted by the light-emitting component 20 to be evenly distributed on the surface of the diaphragm 12, avoiding the problems of uneven light spots or afterimages of the LED beads 212, thereby improving the visual effect and user experience of the speaker 100.

[0048] As shown in Figure 2, in some embodiments, the diffuser plate 221 is formed into an annular plate.

[0049] By designing the diffuser plate 221 as a ring plate, interference between the diffuser plate 221 and the internal structure of the speaker 100 can be avoided, and the light can be distributed more evenly on the surface of the diaphragm 12 of the speaker 100, thus avoiding the problem of uneven light output and improving the visual effect. This structural design allows the light to be evenly distributed on the surface of the diaphragm 12 of the speaker 100, thereby solving the problem of uneven light output after the miniaturization design of the speaker 100.

[0050] The ring-shaped plate can be manufactured using processes such as molding or 3D printing to ensure the precision of its shape and dimensions. Furthermore, the surface of the ring-shaped plate can undergo special treatments, such as adding tiny scattering particles, to further enhance the uniform scattering effect of light.

[0051] In some embodiments, the diffuser plate 221 has silicone particles with a radius ranging from 1.2 μm to 2 μm and a concentration ranging from 30,000 / mm². 3 -80000 / mm 3 .

[0052] Specifically, the diffuser plate 221 contains silicone particles. As diffuser particles, silicone particles have a certain scattering effect on light, which increases the randomness of the light propagation direction and the degree of diffusion. The light emitted after passing through the diffuser plate will be more uniform.

[0053] The concentration of diffusing particles can be adjusted according to needs. The higher the concentration, the better the light diffusion effect and the higher the uniformity. However, due to the increased number of light scattering events, the overall brightness will decrease. The transparent diaphragm 12 can be made of transparent materials such as PP, and the surface is treated with a frosted process to make the light transmission more uniform.

[0054] The radius of the organosilicon particles ranges from 1.2 μm to 2 μm, meaning the radius can be any value within or between 1.2 μm, 1.4 μm, 1.5 μm, 1.6 μm, 1.8 μm, 1.9 μm, and 2 μm; the concentration of the organosilicon particles ranges from 30,000 / mm³. 3 -80000 / mm 3 That is, the concentration of organosilicon particles can be 30,000 / mm³. 3 40000 / mm 3 50000 / mm 3 60000 / mm 3 70000 / mm 3 80000 / mm 3 The value can be any point in the spectrum or any range between the two. This allows the silicone particles to effectively diffuse the light emitted by the light-emitting element 21, thereby improving the uniformity of the light output while ensuring appropriate brightness, and reducing the possibility of seeing the LED bead 212 as a ghost image on the surface of the diaphragm 12.

[0055] In some examples, the radius of the silicone particles can be selected to be around 1.5 μm, which can further improve the uniformity of light while ensuring the diffusion effect. In addition, the concentration of silicone particles can also be adjusted according to actual needs. For example, when a stronger diffusion effect is required, the concentration can be adjusted to close to 80,000 / mm². 3 The upper limit.

[0056] Therefore, by introducing silicone particles with a specific radius and concentration range into the diffuser plate 221, the uniformity of the light output effect of the speaker 100 can be significantly improved, avoiding the problem of the LED bead 212 being seen on the surface of the diaphragm 12, and improving the overall visual effect of the speaker 100.

[0057] As shown in Figures 4 and 5, in some embodiments, the reflective layer 222 is a coating applied to the surface of the diffuser plate 221.

[0058] The reflective layer 222 can be coated with different materials, such as acrylic resin and polyurethane resin. These materials have good reflective properties and durability, ensuring the stability and reliability of the reflective layer 222 during long-term use. The coating process can be spraying, brushing, or rolling, and the specific choice can be adjusted according to production conditions and costs.

[0059] By applying the reflective layer 222 to the surface of the diffuser plate 221, the manufacturing process is simple and facilitates the manufacturing and molding of the reflective element 22.

[0060] In some embodiments, the reflective layer 222 is made of acrylic resin.

[0061] Acrylic resin possesses excellent optical properties, effectively reflecting light and resulting in a more uniform light emission. As the material for the reflective layer 222, acrylic resin can be applied to the side of the diffuser plate 221 facing away from the light-emitting element 21, forming a uniform reflective coating. Acrylic resin can also be mixed with other materials to enhance its reflective properties and durability.

[0062] As shown in Figures 4 and 5, in some embodiments, the light-emitting element 21 includes a lamp board 211 and an LED bead 212. The lamp board 211 is arranged opposite to the reflector 22, and the LED bead 212 is disposed on the lamp board 211 and located on the side of the lamp board 211 closer to the reflector 22.

[0063] The lamp plate 211 and the reflector 22 are arranged opposite to each other. This arrangement allows the light emitted by the lamp beads 212 to be reflected by the reflector 22, thus distributing it evenly on the surface of the diaphragm 12. The lamp beads 212 are located on the lamp plate 211 and on the side closer to the reflector 22, allowing the light to be directly projected onto the reflector 22. After reflection by the reflector 22, the light distribution is more uniform, reducing the occurrence of afterimages of the lamp beads 212.

[0064] The lamp board 211 can be a flexible circuit board or a rigid circuit board, and the lamp beads 212 can be LED lamp beads 212 or other types of light-emitting diodes.

[0065] In the above technical solution, the light-emitting element 21 has a simple structure and a compact arrangement, which meets the design requirements of miniaturization of the speaker 100. At the same time, it helps to distribute light evenly, reduce the appearance of afterimages of the lamp beads 212, and enable the speaker 100 to maintain good light output while miniaturizing, thereby improving the visual experience.

[0066] In some embodiments, the diaphragm 12 is made of a light-transmitting material.

[0067] By using light-transmitting materials, light can pass through the diaphragm 12 evenly. These materials can be implemented in various ways, such as using transparent plastics, glass, or other materials with good light transmission properties. Transparent plastics are lightweight and easy to process, while glass has high rigidity and wear resistance.

[0068] In addition, the light transmission performance of light-transmitting materials can be further optimized by adding different coatings or processing techniques. For example, applying an anti-reflective coating to the material surface can reduce light reflection loss and increase light transmission efficiency.

[0069] As shown in Figures 2 and 3, in some embodiments, the loudspeaker body 10 further includes a spider 13 and a voice coil 14. The outer periphery of the spider 13 is connected to the frame 11, and the inner periphery of the spider 13 is connected to the voice coil 14. An installation space 101 is defined between the diaphragm 12, the spider 13, the voice coil 14, and the frame 11.

[0070] The spider 13 can be made of a highly elastic material to ensure good vibration characteristics and stability in miniaturized design. By using a highly elastic material for the spider 13, sufficient elastic restoring force can be provided in the miniaturized loudspeaker 100 to ensure normal operation of the loudspeaker 100. The voice coil 14 can be made of a lightweight, highly conductive material to reduce weight and improve response speed. In addition, the lightweight, highly conductive material of the voice coil 14 can provide a fast electrical signal response while reducing weight.

[0071] The diaphragm 12, spider 13, voice coil 14 and frame 11 define an installation space 101. The light-emitting component 20 is installed in the installation space 101. That is, the light-emitting component 20 is installed using the space between the diaphragm 12, spider 13, voice coil 14 and frame 11, making the structure of the speaker 100 more compact, while protecting the light-emitting component 20 and reducing the probability of damage to the light-emitting component 20.

[0072] Therefore, through the cooperation of various components, a stable structure and spatial arrangement are provided in the miniaturized speaker 100, thereby solving the problems of uneven light emission and LED bead 212 ghosting on the diaphragm 12 surface. Through the above solution, the speaker 100 can effectively avoid uneven light emission and LED bead 212 ghosting in its miniaturized design, improving visual effects and user experience.

[0073] As shown in Figure 2, in some embodiments, the frame 11 is provided with a limiting rib (not shown in the figure). The limiting rib extends along the arrangement direction of the light-emitting element 21 and the reflector 22. The outer periphery of the light-emitting element 21 is provided with a limiting protrusion 2101, and the outer periphery of the reflector 22 is provided with a limiting groove 2201. The limiting rib can be inserted into the limiting groove 2201, and the limiting protrusion 2101 can abut against one end of the limiting rib. Thus, the limiting rib cooperates with the light-emitting element 21 and the reflector 22 simultaneously. On the one hand, it can realize the positioning of the installation of the light-emitting element 21 and the reflector 22, and at the same time, it can limit the shaking of the light-emitting element 21 and the reflector 22 after they are installed in place. On the other hand, by designing the length of the limiting rib, the light-emitting element 21 and the reflector 22 can be arranged at intervals, and the distance between the light-emitting element 21 and the reflector 22 can be kept within a specific range, thereby improving the light output effect at the diaphragm 12.

[0074] As shown in Figures 2 and 3, in some embodiments, the basin frame 11 has a receiving cavity 1101 with an opening on one side. The outer periphery of the receiving cavity 1101 has a first limiting portion 111 and a second limiting portion 112. The first limiting portion 111 is located outside the second limiting portion 112 and is closer to the opening relative to the second limiting portion 112. The outer periphery of the diaphragm 12 can be mounted to the first limiting portion 111, the reflector 22 can be mounted to the second limiting portion 112, and the limiting rib is located between the first limiting portion 111 and the second limiting portion 112.

[0075] As shown in Figures 2 and 3, the frame 11 forms a receiving cavity 1101 with a multi-step structure. The step at the opening of the receiving cavity 1101 (i.e., the first limiting part 111) is used to install the diaphragm 12. The second step of the receiving cavity 1101 (i.e., the second limiting part 112) in the direction away from the opening (as shown in Figure 3, the direction from top to bottom) is used to install the reflector 22. The limiting rib is located between the two steps, thereby the light-emitting element 21 can be installed between the diaphragm 12 and the reflector 22. The overall structure is compact and easy to assemble, which can meet the design requirements of miniaturization of the loudspeaker 100.

[0076] In some examples, the basin frame 11 also has a third step, which is far away from the first limiter 111 relative to the second limiter 112. The third step can be used to install the spring 13, thereby making full use of the structure of the basin frame 11 to realize the installation of multiple components. The structure is simple and the installation is convenient.

[0077] In addition, a magnet 15 is provided in the receiving cavity 1101 of the frame 11, and a gasket 16 is installed on the opening side of the frame 11. The gasket 16 is connected to the frame 11 and can limit the position of the diaphragm 12 and other structures. Thus, the overall structure is simple, easy to assemble, and can meet the design requirements of miniaturization of the loudspeaker 100.

[0078] As shown in Figure 6, the vehicle according to an embodiment of the present disclosure includes a speaker 100 according to an embodiment of the present disclosure. By employing the speaker 100, the speaker 100 integrates a light-emitting function, and the light-emitting component 20 can achieve a uniform light emission effect in the miniaturized speaker 100. Furthermore, the light-emitting component 21 emits light away from the diaphragm 12 and then reflects the light through the reflector 22, which can increase the optical path between the light source and the diaphragm 12, improve the uniformity of brightness, avoid the afterimage of the LED beads 212 on the surface of the diaphragm 12, and at the same time reduce visual fatigue such as glare caused by the direct exposure of light to the diaphragm 12, improve visual comfort, enhance visual effects, and improve the user experience.

[0079] As shown in Figures 1-5, in some specific embodiments, the loudspeaker 100 uses a diaphragm 12 with a diameter of 2 inches. The LED beads 212 of the light-emitting element 21 are installed on the side of the lamp plate 211 away from the diaphragm 12. The lamp plate 211 with LED beads 212 is installed facing away from the diaphragm 12 of the loudspeaker 100, with a distance of 5 mm between it and the diaphragm 12. At the same time, the reflector 22 is spaced 2 mm to 4 mm away from the light-emitting element 21. The reflector 22 can be placed horizontally or at a certain angle to the horizontal direction towards the diaphragm 12.
