DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In order to make the technical solutions and advantages of the present application clearer, they will be described in detail in conjunction with the drawings below.

[0043] As people's quality of life improves, the use of smart electronic products becomes more and more popular, and smart speakers are one of the popular products among smart electronic products. At present, more and more smart speakers are equipped with mood lights to enhance the aesthetics of the speakers when playing music and create a comfortable and relaxing atmosphere.

[0044] In the related art, the light emitted by the ambient light of the smart speaker is rather dazzling, and generally a soft light cover is provided to soften the light. However, providing a soft light cover on the light propagation path will reduce the brightness of the ambient light and affect the user experience.

[0045] In this regard, the present application provides a speaker, such as Figure 1 , Figure 2 and Figure 3 As shown, the speaker includes a shell 1, a light source 2 and a light guide part 3; the shell 1 has a accommodating cavity 11, and the light source 2 and the light guide part 3 are fixed in the accommodating cavity 11; the light entrance of the light guide part 3 has a polished surface 31, and the light exit of the light guide part 3 is provided with a soft light structure 32, wherein the polished surface 31 is located on the light exit side of the light source 2.

[0046] In the speaker provided in the embodiment of the present application, a light guide part 3 is arranged inside the shell 1, and the light of the light source 2 is guided to the outside through the light guide part 3, thereby realizing the transmission of light, and a soft light structure 32 is arranged at the light outlet of the light guide part 3, so that the light emitted to the outside becomes softer, and a polished surface 31 is arranged at the light entrance of the light guide part 3, so that the diffuse reflection of light on the surface of the light guide part 3 is reduced, so that more light is propagated along the light guide part 3, and the amount of light entering the light guide part 3 is increased. Compared with the speaker in which a soft light cover is arranged outside the light source 2 in the related technology, the light is softened, and the glare of the light is avoided while ensuring the brightness of the atmosphere light.

[0047] In some embodiments, there are multiple light guides 3, and each light guide 3 corresponds to a light source 2, so as to ensure that the atmosphere light can emit light in all directions to enhance the atmosphere of each area around the speaker. For example, there are four light guides 3, and the cross-sectional shape of the housing 1 along the height direction is rectangular. The four light guides 3 are respectively located on the inner sides of the four peripheral walls of the housing 1 and connected to the housing 1.

[0048] In some embodiments of the present application, the orthographic projection of the light source 2 on the plane where the polished surface 31 is located is located inside the polished surface 31, and the polished surface 31 is located on the light output side of the light source 2, so that all light emitted from the light source 2 to the light guide part 3 can pass through the polished surface 31 and enter the light guide part 3, avoiding light loss, thereby increasing the amount of incoming light and ensuring the brightness of the atmosphere light.

[0049] In addition, part of the light emitted from the light source 2 has a certain angle with the axial direction of the light source 2, that is, the projection of the light emitted by the light source 2 on the polishing surface 31 is circular. In order to ensure that all the light can enter the light guide part 3, the projection of the light emitted by the light source 2 on the polishing surface 31 is also located inside the polishing surface 31.

[0050] It should be noted that the size and shape of the polishing surface 31 can be adjusted according to the distance between the light source 2 and the polishing surface 31 and the light output angle of the light source 2 to ensure that all the light emitted by the light source 2 can enter the light guide 3 .

[0051] Optionally, the surface roughness of the polishing surface 31 is not greater than 0.01 micrometers, and those skilled in the art may adjust the surface roughness of the polishing surface 31 according to the brightness requirements of the ambient light.

[0052] In some embodiments of the present application, Figure 5 As shown, at least a portion of a first surface 322 of the soft light structure 32 has a texture 321 , and the first surface 322 is a surface of the soft light structure 32 that is away from the light guide portion 3 .

[0053] The first surface 322 of the soft light structure 32 has a texture 321 , and the texture 321 can soften the light, ensuring that the light emitted by the light source 2 is evenly dispersed after passing through the texture 321 , making the light of the ambient light softer.

[0054] It should be noted that the texture 321 can be arranged in a variety of ways, and those skilled in the art can select and adjust the shape, structure and arrangement of the texture 321 according to needs.

[0055] Optionally, the texture 321 can be any one of a plurality of concentric circles, a plurality of concentric ellipses and a plurality of polygons, or can be other types of textures 321 such as a matte texture 321 and a frosted texture 321, as long as the high transmittance of light and the uniformity of the emitted light can be guaranteed.

[0056] Exemplarily, the texture 321 provided in the embodiment of the present application is a plurality of concentric circles arranged on the first surface 322, and the light emitted by the light source 2 passes through the polishing surface 31, the light guide portion 3 and the texture 321 in sequence and then emits to the outside; wherein, the spacing between adjacent concentric circles can be adjusted based on parameters such as light interference and diffraction.

[0057] In some embodiments of the present application, the light guiding portion 3 is a transparent structure.

[0058] The light guide part 3 is a transparent structure, which has a light guiding function. The polished surface 31 can be directly processed on the light guide part 3 to increase the amount of light entering. Compared with using non-transparent components to make the light guide part 3, the manufacturing cost is saved.

[0059] Optionally, the light guide portion 3 is a light guide made of plastic.

[0060] According to the above embodiments, since the light guide part 3 may be a transparent structure, after the light enters the light guide part 3 , part of the light may pass through the transparent light guide part 3 and be emitted to the outside, resulting in a certain amount of light loss.

[0061] Therefore, in some embodiments of the present application, Figure 6 As shown, the sound box may further include a first light reflecting portion 4 , which wraps the light guiding portion 3 between the polishing surface 31 and the soft light structure 32 .

[0062] The first light reflecting part 4 is wrapped on the outside of the light guiding part 3, so that the light directed to the outside of the light guiding part 3 is blocked by the first light reflecting part 4 and is reflected by the first light reflecting part 4 to the outside, thereby avoiding the light loss caused by the light penetrating the light guiding part 3 and ensuring the brightness of the atmosphere light.

[0063] In some embodiments, the light guide portion 3 is linear, and a polished surface 31 and a soft light structure 32 are respectively provided on both sides of the light guide portion 3. The light emitted by the light source 2 passes through the polished surface 31, the light guide portion 3 and the soft light structure 32 in sequence before being emitted to the outside.

[0064] In the above embodiment, the center of the light source 2 is located on the axis of the light guide 3. When the light source 2 is turned on, the user can directly see the light source 2 from the outside, which is dazzling to the user, affecting the user experience and not aesthetically pleasing.

[0065] In some embodiments, Figure 6As shown, the surface of the light guide portion 3 away from the light outlet is an arc-shaped surface, which protrudes in the direction away from the bottom surface 14 of the sound box; wherein the polished surface 31 and the first surface 322 are perpendicular to each other, and the first surface 322 is parallel to the bottom surface 14.

[0066] In the speaker provided in the embodiment of the present application, the polished surface 31 and the first surface 322 are arranged vertically, and one side surface of the light guide part 3 is arranged as an arc-shaped surface, so that most of the light emitted by the light source 2 into the light guide part 3 is guided by the light guide part 3 and reflected by the first light reflecting part 4, and then propagates in a direction perpendicular to the bottom surface of the speaker, instead of being directly emitted to the outside. The user cannot directly see the light source outside the speaker, which avoids the light emitted by the light source being too glaring, thereby improving the user's experience; and, by setting one side of the light guide part 3 as a curved surface, the light can be better focused and guided.

[0067] In some embodiments of the present application, Figure 4 and Figure 7 As shown, a light-transmitting opening 12 is opened on the outer wall of the shell 1; the sound box also includes a second light-reflecting portion 5, which is located on the side of the light-guiding portion 3 close to the bottom surface and is respectively connected to the shell 1 and the light-guiding portion 3, and the second light-reflecting portion 5 is used to reflect the light emitted from the soft light structure 32 to the outside of the light-transmitting opening 12.

[0068] The speaker provided in the embodiment of the present application, by providing a second reflective portion 5, guides the light emitted by the light source 2 to the outside through the light-transmitting port 12 through two reflections. Compared with the above-mentioned embodiment, not only the light source 2 can be hidden, but also the propagation distance of the light can be made longer; and, compared with directing the light toward the placement plane of the speaker (such as a desktop or the ground), the effect of the ambient light is better, further enhancing the sense of atmosphere.

[0069] In some embodiments of the present application, Figure 4 As shown, there are multiple light-transmitting openings 12 , which are spaced apart along the circumference of the sound box, and a light-shielding structure 13 is provided between two adjacent light-transmitting openings 12 .

[0070] By providing a plurality of light-transmitting openings 12 and a plurality of light-shielding structures 13, the light-emitting area of ​​the speaker can be divided into a plurality of areas, thereby emitting light in various directions and improving the atmosphere in various areas around the speaker. For example, the cross-section of the speaker along the height direction is rectangular, the number of light-transmitting openings 12 can be four, the number of light-shielding structures 13 is also four, and the light-shielding structures 13 are respectively located at the four corners of the speaker, dividing the light-emitting area around the speaker into four areas, and the light source emits light to the front, rear, left and right of the speaker respectively.

[0071] In some embodiments of the present application, the shell 1 also includes a mounting plate 15, which is located on a side of the light guide portion 3 away from the light transmitting port 12 and is connected to the shell 1, wherein the mounting plate 15 is parallel to the bottom surface 14 and arranged at intervals; the light source 2 includes a plurality of light-emitting units 21, which are located on a side of the mounting plate 15 away from the bottom surface 14 and are distributed at intervals along the circumference of the mounting plate 15.

[0072] In some embodiments, Figure 1 As shown, each light guide portion 3 can extend along the width direction or the length direction of the speaker, and the light source 2 corresponding to the light guide portion 3 can include a plurality of light emitting units 21, and the plurality of light emitting units 21 are arranged along the circumference of the mounting plate 15 to emit light from a plurality of light-transmitting openings 12, thereby increasing the light output and enabling the light emitted to the outside to be more uniform.

[0073] In some embodiments, Figure 7 and Figure 8 As shown, the second reflective portion 5 may include a connecting member 51 and a reflective member 52, the connecting member 51 being connected to the shell 1 and the light guide portion 3 respectively; the connecting member 51 includes a slope 511, the slope 511 is inclined so as to be closer to the bottom surface 14 as it is farther away from the light source 2, and at least part of the reflective member 52 is laid on the slope 511.

[0074] The speaker provided in the embodiment of the present application is provided with an inclined surface 511 and a reflective member 52 is laid on the inclined surface 511, so that the light emitted from the light outlet of the light guide part 3 to the ground is reflected at the inclined surface 511, that is, the light emitted to the outside through the light-transmitting port 12 is not directly emitted to the ground, but forms a certain angle with the ground, so that the light can be transmitted over a longer distance and the effect of the atmosphere light will be better.

[0075] Optionally, those skilled in the art may select and adjust the inclination angle of the inclined surface 511 according to actual needs.

[0076] Optionally, the first reflective portion 4 and / or the reflective element 52 is a reflective structure made of reflective paint.

[0077] Exemplarily, the first reflective portion 4 is a paint coating, and the reflective element 52 is a mirror coating.
