[0006] Preferably, the semi-transparent lens sheet and the liquid crystal screen are tightly matched or loosely matched.

[0007] Preferably, the backlight module includes a light guide plate and a light emitting circuit board, which is arranged at the edge and / or back of the light guide plate. The light guide plate is illuminated by the light emitting circuit board, thereby forming a uniformly luminous surface light source on the front of the light guide plate.

[0008] Preferably, the audio control circuit is provided with an AI voice control module, which includes a voice control chip and at least two sound pickup heads.

[0009] As an improvement of one aspect of the above technical solution, it also includes one or more speaker assemblies, the speaker assembly includes a speaker shell and a speaker arranged on the speaker shell, and the speaker is driven by an audio control circuit.

[0010] Preferably, one or more bass radiators are provided on the speaker housing.

[0011] Preferably, the housing is provided with a transparent decorative plate placed in front of the semi-transparent lens sheet, and the sound box assembly further comprises one or more external speakers embedded in the transparent decorative plate, and the external speakers are also driven by the sound control circuit.

[0021] like Figures 1 to 5 As shown, in one embodiment, the audio system with naked-eye 3D visual effects of the utility model includes a shell 1, a display component 2 arranged on the shell 1, and an audio control circuit 3 arranged in the shell 1, the display component 2 is driven by the audio control circuit 3, and the display component 2 includes a liquid crystal screen 21, a backlight module 22 arranged on the back of the liquid crystal screen 21, and a semi-transparent lens sheet 23 arranged on the front of the liquid crystal screen 21; wherein, the incident light on the front of the semi-transparent lens sheet 23 forms a virtual image behind the liquid crystal screen 21.

[0022] The audio system with naked-eye 3D visual effects in the above embodiment can be used to drive an external speaker. Since the access method of the external speaker and the circuit connection of the display module and the audio control circuit can be obtained according to the prior art, the utility model will not elaborate on them.

[0023] The semi-mirror sheet 23 in the above embodiment is a currently known semi-mirror, which is specifically made by vacuum plating on the lens so that a part of the incident light can be transmitted and another part can be reflected. The common ratio is five-to-five or seven-to-three.

[0024] Therefore, in the above embodiment, the incident light on the front side of the semi-transparent lens 23 forms a virtual image behind the liquid crystal screen 21, so that the picture of the liquid crystal screen 21 appears to float in the virtual image in the eyes of the user. Although the structure is simple, the effect is very significant. Specifically, the user can see the mirror image of the real world through the semi-transparent lens 23, and at the same time see the picture of the liquid crystal screen 21 appear in the mirror image of the real world through the semi-transparent lens 23, thereby producing a naked eye 3D special effect painted in the scene.

[0025] Based on a large number of experimental evaluations, the applicant found that for the desired effect of the present invention, the transmittance and emissivity of the semi-transparent lens sheet have extremely wide compatibility, with a transmittance of 20% to 80% for incident light and a corresponding reflectivity of 80% to 20%. The present invention can achieve ideal naked-eye 3D effects within this range.

[0026] Preferably, the semi-transparent lens sheet 23 and the liquid crystal screen 21 are tightly matched or loosely matched.

[0027] Preferably, the backlight module 22 includes a light guide plate 221 and a light emitting circuit board 222. The light emitting circuit board 222 is arranged on the edge and / or back of the light guide plate 221. The light guide plate 221 is illuminated by the light emitting circuit board 222, thereby forming a uniformly luminous surface light source on the front of the light guide plate 221.
