AI Technical Summary
Existing speaker ambient lights lack a reasonable diffusion structure, causing the light emitted by the LEDs to directly illuminate the area, resulting in uneven brightness in certain areas. Increasing the density of LEDs to improve brightness uniformity would increase production costs.
A light-shielding block and a diffusion notch are set on the mounting bracket. The light emitted by the LED beads enters the light guide through the diffusion notch. Combined with the reflection and diffusion groove of the light guide, the light is diffused evenly. The light-shielding block is fixed by the snap-fit groove, which reduces the number of LED beads and reduces costs.
This achieves uniform light diffusion, reduces the number of LED beads, lowers production costs, and enhances the product's market competitiveness and aesthetics.

Description
Technical Field
[0001] This utility model relates to the field of speaker equipment technology, specifically to a speaker ambient light with uniform diffusion. Background Technology
[0002] A speaker is a device that converts audio signals into sound, amplifies the audio signal, and then emits the sound. With societal development and rising living standards, people have greater ability and willingness to engage in entertainment. Most customers want products with enhanced entertainment features. For speakers, advancements can extend beyond simply pursuing high-quality sound; they can also include other entertainment features, such as the strategic use of ambient lighting.
[0003] Ambient lighting in speakers typically consists of LED chips and a light guide plate. Current ambient lighting in speakers lacks a proper diffusion structure; the light emitted by the LED chips directly hits the light guide plate and diffuses outwards, resulting in areas with LED chips being significantly brighter than areas without them. To address this, current methods increase the density of the LED chips and reduce the gaps between them to achieve more uniform brightness. However, this approach inevitably increases manufacturing costs and hinders market competitiveness. Utility Model Content
[0004] To address some or all of the problems existing in the prior art, this utility model provides a speaker ambient light with uniform diffusion, comprising an end cap, a circuit board, a mounting bracket, and a semi-transparent light guide. The mounting bracket is connected to the end cap, the circuit board is connected to the mounting bracket, and the light guide is connected to the mounting bracket, with the light guide sleeved around the periphery of the mounting bracket. The circuit board is provided with multiple LED beads, the light emitted by the LED beads illuminating the light guide. The mounting bracket is provided with light-shielding blocks and diffusion notches at positions corresponding to the LED beads, the light-shielding blocks being located directly in front of the LED beads, and the diffusion notches being located on the left and right sides of the LED beads.
[0005] As a further improvement of this utility model, a snap-fit groove is provided on the light guide at a position corresponding to the light-shielding block, and the light-shielding block is interference-fitted with the snap-fit groove.
[0006] As a further improvement of this utility model, the depth of the snap-fit groove is not less than 80% of the thickness of the light guide.
[0007] As a further improvement of this utility model, the inner wall of the light guide is provided with an arc-shaped light guide surface for reflecting the light emitted by the lamp beads.
[0008] As a further improvement of this utility model, the light guide is provided with arched diffusion grooves at the corresponding positions of the lamp beads, and the arched diffusion grooves are sleeved around the lamp beads.
[0009] As a further improvement of this utility model, the light-shielding block and the mounting bracket are integrally formed.
[0010] As a further improvement of this utility model, it also includes a semi-transparent decorative ring, which is connected to the end cap and is sleeved around the light guide.
[0011] As a further improvement of this utility model, both the decorative ring and the light guide are made of acrylic material, and the decorative ring and the light guide are different colors.
[0012] As a further improvement of this utility model, the number of LED beads is 15, and the 15 LED beads are distributed in a circular array on the circuit board.
[0013] On the other hand, this utility model also provides a smart speaker including the above-mentioned speaker ambient light, and further includes a shell, wherein a speaker is provided inside the shell, the speaker is electrically connected to the circuit board, and the light guide is connected to the shell.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention utilizes a light-shielding block on the mounting bracket to block direct light from the LED beads. Combined with diffusion notches on both sides of the LED beads, the light is guided to the sides, eliminating localized bright spots in the light guide and ensuring more uniform light dispersion. This allows for a reduction in the number of LED beads while maintaining the same luminous efficacy uniformity, thereby lowering the overall manufacturing cost of the ambient light and enhancing the product's market competitiveness. In operation, the light emitted by the LED beads cannot directly penetrate the light-shielding block; it can only pass horizontally through the diffusion notches into the light guide. After reflection and diffusion by the light guide, the light disperses outwards, resulting in a more uniform luminous emission when observed from the outside. Attached Figure Description

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.
[0024] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.
[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0026] like Figure 1-6As shown, a speaker ambient light with uniform diffusion includes an end cap 1, a circuit board 2, a mounting bracket 3, a translucent light guide 4, and a translucent decorative ring 5. The mounting bracket 3 is fixedly connected to the end cap 1 by screws. The circuit board 2 is fixedly mounted on the mounting bracket 3. The light guide 4 is fixedly connected to both the mounting bracket 3 and the end cap 1, and is sleeved around the periphery of the mounting bracket 3. The light guide 4 is used to reflect and diffuse light. Multiple LED beads 6 are soldered on the circuit board 2. The LED beads 6 are used to emit light, and the light emitted by the LED beads 6 can illuminate the light guide 4. The mounting bracket 3 is provided with a light-shielding block 31 and a diffusion notch 32 at the corresponding positions of the LED beads 6. The light-shielding block 31 is located directly in front of the LED beads 6 and is used to block the light emitted by the LED beads 6 from shining outward directly. The diffusion notch 32 is located on the left and right sides of the LED beads 6 and is used to guide the light emitted by the LED beads 6 to the light guide 4.
[0027] During operation, the light emitted by LED 6 cannot directly penetrate the light-shielding block 31. Instead, it passes horizontally through the diffusion gap 32 into the light guide 4. After reflection and diffusion by the light guide 4, the light radiates outward, making the light emitted by the light guide 4 more uniform when observed by the user. This uniformly diffused speaker ambient light, by using the light-shielding block 31 on the mounting bracket 3 to block the direct light from LED 6, and in conjunction with the diffusion gaps 32 on both sides of LED 6 to guide the light to both sides of LED 6, eliminates local bright spots on the light guide 4, making the light emitted by LED 6 more uniformly diffused outward through the light guide 4. Under the same light efficiency uniformity, the number of LEDs 6 can be reduced, thereby reducing the overall manufacturing cost of the ambient light and enhancing the product's market competitiveness.
[0028] To improve structural stability, corresponding slots 41 are provided on the light guide 4 at positions corresponding to the light-shielding blocks 31. The light-shielding blocks 31 are inserted into the corresponding slots 41 with an interference fit. Through the cooperation between the slots 41 and the light-shielding blocks 31, the light guide 4 is connected and fixed to the mounting bracket 3, thereby improving the structural stability.
[0029] In order for the light-shielding block 31 to effectively block the light emitted by the lamp bead 6 from shining outwards, the depth of the locking groove 41 needs to be no less than 80% of the thickness of the light guide 4, that is, the light-shielding block 31 can extend into the light guide 4 with a thickness of more than 80%. In this embodiment, the depth of the locking groove 41 is 85% of the thickness of the light guide 4.
[0030] In this embodiment, the light-shielding block 31 and the mounting bracket 3 are integrally formed; in other embodiments, the light-shielding block 31 and the mounting bracket 3 can also be two independent components, which can be fixed together by snap-fit or other means.
[0031] To ensure uniform light diffusion within the light guide 4, an arc-shaped light guide surface 42 is provided on the inner wall of the light guide 4. The arc-shaped light guide surface 42 is used to reflect the light emitted by the LED beads 6. When the light emitted by the LED beads 6 enters the light guide 4 through the diffusion notch 32, the light will illuminate the arc-shaped light guide surface 42. The arc-shaped light guide surface 42 can reflect and diffuse the light, thereby allowing the light from each LED bead 6 to mix within the light guide 4, making the light more uniformly diffused outward after passing through the light guide 4.
[0032] To further improve the uniformity of light effect, arched diffusion grooves 43 are respectively provided on the light guide 4 at corresponding positions to the lamp beads 6, and the arched diffusion grooves 43 are fitted around the lamp beads 6. During operation, the light emitted by the lamp beads 6 will first illuminate the arched diffusion grooves 43. Because the diffusion grooves are arched, the light can enter the light guide 4 more evenly, making the light emitted outward through the light guide 4 more uniform.
[0033] The decorative ring 5 is fixedly connected to the end cap 1 and is fitted around the light guide 4. The decorative ring 5 enhances the aesthetics of the ambient light, thereby improving the user's experience. When in operation, the light emitted by the LED 6 shines onto the light guide 4 and diffuses outward. Part of the light guide 4 is blocked by the decorative ring 5, so the light enters the decorative ring 5 before diffusing outward, resulting in two rings of light visible to the user from the outside, thus enhancing the overall aesthetics.
[0034] In this embodiment, both the decorative ring 5 and the light guide 4 are made of acrylic material, and the decorative ring 5 and the light guide 4 are different colors. Acrylic has a certain degree of light transmittance, allowing the light emitted by the LED 6 to pass through the light guide 4 and the decorative ring 5 sequentially; and the fact that they are made of different colors allows the user to see two distinct light rings when viewing the ambient light from the outside, further enhancing the aesthetics of the ambient light.
[0035] In this embodiment, there are 15 LEDs 6, and the 15 LEDs 6 are arranged in a circular array on the circuit board 2. In other embodiments, the number of LEDs 6 can be any other number.
[0036] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
