[0048] The technical solution of the utility model is to respectively arrange the first light guide structure 11 and the second light guide structure 12 on the circumferential side wall surface and the top wall surface of the accommodating cavity 1, so as to guide the light in the accommodating cavity 1 to the outside of the light guide shell 100, thereby greatly improving the light output brightness and light output uniformity of the light guide shell 100; and due to the double-layer stacked light output method, the light guide shell 100 has a relatively three-dimensional light output effect, which is more aesthetically pleasing and greatly improves the user's viewing experience.

[0049] For further information, please refer to Figure 1 and Figure 2The light guide housing 100 includes a mounting shell assembly 2 and a cover assembly 3; a receiving space with at least one end open is formed in the mounting shell assembly 2; the cover assembly 3 is covered at the opening of the receiving space, and is arranged to cover the opening of the receiving space, and together with the receiving space forms the receiving cavity 1; wherein the first light guide structure 11 is formed on the mounting shell assembly 2, and the second light guide structure 12 is formed on the cover assembly 3. It can be understood that, for the consideration of installation and assembly, the light guide shell 100 adopts a split setting, that is, the light guide shell 100 is assembled by the mounting shell component 2 and the cover plate component 3; specifically, the mounting shell component 2 forms the accommodating space with at least one end open; the cover plate component 3 covers the opening of the accommodating space and is set to cover the opening of the accommodating space, and then, the cover plate component 3 and the accommodating space together form the accommodating cavity 1; in particular, the first light guide structure 11 is formed on the mounting shell component 2, and the second light guide structure 12 is formed on the cover plate component 3. Therefore, by dividing the light guide shell 100 into the mounting shell component 2 and the cover plate component 3, the first light guide structure 11 and the second light guide structure 12 are respectively arranged on the mounting shell component 2 and the cover plate component 3, so that each component is easy to process, and the light guide shell 100 is easy to assemble and form, which greatly reduces the difficulty of manual production.

[0050] For further information, please refer to Figure 4The mounting shell assembly 2 includes an inner shell 21, an outer shell 22 and a first light guide member 23; the inner shell 21 forms the accommodating space; the outer shell 22 is sleeved on the outer side of the inner shell 21; the first light guide member 23 is arranged between the inner shell 21 and the outer shell 22; one end of the first light guide member 23 extends into the accommodating space, and the other end extends to the outer side wall of the outer shell 22, so as to guide the light in the accommodating space to the outside of the outer shell 22; wherein, the first light guide structure 11 includes the first light guide member 23. It can be understood that the mounting shell assembly 2 forms the accommodating space. Specifically, the mounting shell assembly 2 is composed of the inner shell 21, the outer shell 22 and the first light guide 23, wherein the accommodating space is formed by the inner shell 21; the outer shell 22 is sleeved on the outer side of the inner shell 21 to protect the inner shell 21 from being damaged by external force, thereby protecting the stability and reliability of the accommodating space; the first light guide 23 is arranged between the inner shell 21 and the outer shell 22; one side of the first light guide 23 is provided with a plurality of light guides, and the light guides are provided with a plurality of light guides.

[0051] It can be understood that, for the sake of light guiding efficiency, 0.1% of light diffuser is added to the material of the first light guide member 23 to improve the light guiding efficiency and reduce the loss of light when propagating in the first light guide member 23, thereby improving the light output brightness of the first light guide member 23 and enabling the first light guide member 23 to better guide the light inside the accommodating cavity 1 to the outside of the accommodating cavity 1; in addition, the light emitting surface of the first light guide member 23 adopts an etching process, and an optical microstructure is made on the surface, so that the light is softer and more uniform, which further sets off the beauty of the light guide shell 100 and improves the user experience.

[0052] For further information, please refer to Figure 1 and Figure 2The mounting shell assembly 2 also includes a top shell 24, which is mounted on the inner shell 21 and is spaced apart from the outer shell 22 along the axial direction of the outer shell 22; a light-transmitting gap is formed between the top shell 24 and the outer shell 22; and the first light guide 23 extends into the light-transmitting gap. In some embodiments, the first light guide 23 is sandwiched between the inner shell 21 and the outer shell 22, so that its end face facing the outside of the outer shell 22 is exposed, which is not beautiful on the one hand, and the first light guide 23 is easily damaged on the other hand. Therefore, the mounting shell assembly 2 also includes the top shell 24, which is installed on the inner shell 21 and is spaced apart from the outer shell 22 along the axial direction of the outer shell 22; the light-transmitting gap is formed between the top shell 24 and the outer shell 22; the first light guide 23 extends into the light-transmitting gap, and the light-transmitting gap formed between the top shell 24 and the outer shell 22, on the one hand, protects the first light guide 23 from being easily damaged by external force, and on the other hand, the light inside the accommodating cavity 1 can be guided to the outside of the outer shell 22 through the light-transmitting gap.

The cover plate 32 and the second light guide can be bonded or bolted. Here, there is no specific limitation on how the cover plate 32 and the second light guide are connected. In addition, for light guiding efficiency considerations, the surface of the second light guide is sprayed with white ink to increase the reflectivity and improve the optical efficiency, so as to reduce the loss of light when it propagates in the second light guide, thereby improving the brightness of the light. 0.1% of light diffuser is added to the material of the second light guide to enable the second light guide to better guide the light inside the accommodating cavity 1 to the outside of the accommodating cavity 1.

[0055] For further information, please refer to Figure 5 , the cover assembly 3 also includes a rubber ring 33, which is sleeved on the second light guide. It can be understood that the sound of the speaker 300 can also pass out from the light guide shell 100. Since the accommodating cavity 1 of the light guide shell 100 is a closed arrangement, there will be times when the air pressure inside and outside the accommodating cavity 1 is different. Therefore, the sound transmitted from the light guide shell 100 is different from the sound transmitted from other parts of the speaker 300, which greatly reduces the user's experience. Therefore, the cover assembly 3 also includes the rubber ring 33, which is sleeved on the second light guide to neutralize the air pressure inside and outside the accommodating cavity 1, improve the sound quality, and thus bring a good user experience.
