[0045] Figure 1-Figure 3 : is a structural diagram of the audio device of this embodiment. The audio device may be a speaker. In this embodiment, the speaker is a speaker with a screen, which can achieve the effect of 360-degree continuous display of content, so that the online content can follow the screen display of the speaker, forming a new speaker form.

[0046] like Figure 1-Figure 3As shown, the audio device includes an at least partially transparent shell 1, an upper inner bracket 2, a lower inner bracket 3, a light board fixing bracket 4 and a light board 5. The upper inner bracket 2 and the lower inner bracket 3 are installed in the shell 1, the upper inner bracket 2 is located above the lower inner bracket 3, and a cavity is formed between the upper inner bracket 2, the lower inner bracket 3 and the shell 1. The light board fixing bracket 4 is installed in the cavity, and the light board 5 is fixed on the side of the light board fixing bracket 4 facing the shell 1. When the light board fixing bracket 4 is controlled to rotate at a high speed, it drives the light board 5 fixed thereon to rotate at a high speed in the cavity. Under the visual delay effect, the user can see that the light of the light board 5 is continuously and uninterruptedly transmitted from the transparent part of the shell 1 in the circumferential direction, so that the transparent shell can achieve a colorful screen-like display effect. The above-mentioned transparent shell and the internal rotating light board and other structures greatly reduce the cost compared to the curved screen.

[0047] like Figure 2 As shown, a connecting cavity 100 is formed between the bottom surface of the upper inner bracket 2 and the top surface of the lower inner bracket 3, and a rotating cavity 200 is formed between the side surface of the upper inner bracket 2, the side surface of the lower inner bracket 3 and the inner side surface of the outer shell 1. The rotating cavity 200 is connected with the connecting cavity 100 to form the above-mentioned cavity.

[0048] like Figure 3 As shown, the light board fixing bracket 4 includes a connecting frame 41 and at least one light board bracket 42 fixed on the outside of the connecting frame 41. Among them, the connecting frame 41 is located in the connecting cavity 100, the light board bracket 42 is located in the rotating cavity 200, and the light board 5 is fixed on the side of the light board bracket 42 facing the outer shell 1. When the light board fixing bracket 4 rotates at a high speed, the connecting frame 41 rotates in the connecting cavity 100, and the light board bracket 42 drives the light board 5 to rotate in the rotating cavity 200, so that the light of the light board 5 can be transmitted from the transparent part of the outer shell 1. The light board fixing bracket 4 will not collide with other structures during the rotation process. Preferably, in order to ensure the display effect of the light emitted by the light board 5, the light board 5 and the light board bracket 42 are set to a structure similar to the busbar of the rotating cavity 200, and are arranged in parallel in the rotating cavity 200, thereby improving the display effect and preventing collision with other structures, thereby improving the safety performance of the audio equipment.

[0049] In this embodiment, the housing 1 is a rotating body structure with the top and bottom connected, the upper inner bracket 2 is a rotating body with a bottom surface, and the lower inner bracket 3 is a rotating body with a top surface. After the upper inner bracket 2 and the lower inner bracket 3 are installed in the housing 1, a cavity is formed for the light board fixing bracket 4 to rotate.

[0050] like Figure 1 and Figure 2As shown, the outer shell 1 includes an upper transparent shell 11, a lower transparent shell 12 and an intermediate bracket 13, and the intermediate bracket 13 connects the upper transparent shell 11 and the lower transparent shell 12 to form an integral structure that is through from top to bottom. Among them, after the upper inner bracket 2 and the lower inner bracket 3 are installed in the outer shell 1, the upper inner bracket 2 is arranged opposite to the upper transparent shell 11, and the lower inner bracket 3 is arranged opposite to the lower transparent shell 12. The upper inner bracket 2 and the lower inner bracket 3 can be used to shield other internal structures except the light board 5 and the light board bracket 42, so as to prevent the internal structure from being seen by the user and affecting the appearance of the product. Among them, the light of the light board 5 can be transmitted from the upper transparent shell 11 and the lower transparent shell 12.

[0051] Preferably, the bottom surface of the upper inner bracket 2 and the top surface of the lower inner bracket 3 extend to the inner side of the intermediate bracket 13, respectively, and can further shield other structures except the light board 5 and the light board bracket 42. That is, the height of the upper inner bracket 2 is greater than the height of the upper transparent shell 11, and the height of the lower inner bracket 3 is greater than the height of the lower transparent shell 12.

[0052] In this embodiment, the revolving surface of the upper inner bracket 2 is the same as and parallel to the revolving surface of the upper transparent shell 11, and the revolving surface of the lower inner bracket 3 is the same as and parallel to the revolving surface of the lower transparent shell 12, thereby improving the aesthetics of the revolving cavity 200. Among them, the shape of the light board bracket 42 is the same as the generatrix shape of the revolving body formed by the upper transparent shell 11, the lower transparent shell 12 and the intermediate bracket 13, so that the light board bracket 42 can be arranged in parallel in the revolving cavity 200, so that when the light board bracket 42 drives the light board 5 to rotate, it will not collide with other structures.

[0053] Among them, the revolving surface of the upper inner bracket 2, the revolving surface of the lower inner bracket 3, the revolving surface of the upper transparent shell 11, and the revolving surface of the lower transparent shell 12 can be one of the cylindrical side surface, spherical surface and conical surface. In addition, the revolving surface of the upper inner bracket 2, the revolving surface of the lower inner bracket 3, the revolving surface of the upper transparent shell 11, and the revolving surface of the lower transparent shell 12 can also be a revolving surface structure formed by rotating other generatrixes. Among them, the upper inner bracket 2 and the lower inner bracket 3 are basically symmetrical structures relative to the horizontal plane, and the upper transparent shell 11 and the lower transparent shell 12 are basically symmetrical structures relative to the horizontal plane. The intermediate bracket 13 is a hyperbolic paraboloid or a saddle surface, and the characteristic of the hyperbolic paraboloid is that two opposite directions are curved. Thus, the intermediate bracket 13 connects the upper transparent shell 11 and the lower transparent shell 12 to maintain a symmetrical structure. The intermediate bracket 13 can be a non-transparent structure, which is used to shield the connecting frame 41 and the structure fixed thereon.

[0054] In this embodiment, the revolving surfaces of the upper inner bracket 2, the lower inner bracket 3, the upper transparent shell 11, and the lower transparent shell 12 are the side surfaces of the truncated cone revolving body.

In this embodiment, the upper light group 51 and the lower light group 52 are both arranged with a plurality of LED lights in the height direction. The light board 5 can be fixed to the light board bracket 42 by bonding, screws, etc.

[0056] Preferably, the light board fixing bracket 4 includes a connecting frame 41 and more than two light board brackets 42.

The multiple light board brackets 42 are all located in parallel in the rotating cavity 200, and a light board 5 of the above structure is fixed on each light board bracket 42. The connecting frame 41 drives multiple light boards 5 to rotate at high speed at the same time, which can further improve the continuity of the display effect.

[0057] The outer shell 1, the upper inner bracket 2, the lower inner bracket 3 and the connecting frame 41 are coaxially arranged, and the driver 8 drives the connecting frame 41 to rotate around the central axis to improve the rotation effect and the display effect.

The main board 10 is used to control the driver 8 to rotate at high speed. The encoder 101 is used to read the rotation speed of the driver 8 and feed it back to the main board 10, so that the main board 10 can accurately control the movement of the driver 8. In this embodiment, the driver 8 is a servo motor.
