However, the installation of the display module is limited by the structure of the housing, and the portable intelligent sound box is usually small in size, so that the installation space for the display module is small, the display module is usually embedded in the housing directly, the display module is exposed out of the housing, and the display module is easily damaged due to environmental interference such as hard collision, so that the problem of poor working stability exists.

And, display module during operation is at its surface imaging, and display module is fixed in the casing surface, and when intelligent stereo set is comparatively short for the user, the user generally needs the low head to watch the display module on the casing, and the viewing angle has been restricted to the structure of intelligent stereo set, influences user experience.

On the other hand, the mode of interaction between the intelligent sound equipment and the user in the related technology is usually voice interaction or key operation interaction, and the interaction mode is monotonous.

Therefore, the embodiment of the application provides an intelligent sound box.

Referring to fig. 1 and 2, the intelligent sound box includes a housing 1, a display module 2 and an optical element 3 with equivalent negative refractive index, wherein the housing 1 is provided with a receiving cavity 11, the display module 2 and the optical element 3 with equivalent negative refractive index are both disposed in the receiving cavity 11, a display opening 12 is disposed at one side of the housing 1, and the display opening 12 penetrates through the housing 1 to communicate the receiving cavity 11 with an external space.

The display module 2 is accommodated in the accommodating cavity 11, and the display module 2 is fixed on the shell 1. The display module 2 has a distance from the display port 12 and faces the display port 12. The display module 2 has a light emitting direction, which is a direction in which the display module 2 emits light when operating. The display module 2 faces the display port 12, which means that one side of the display screen of the display module 2 faces the display port 12, and the light emitting direction of the display module 2 faces the display port 12.

The equivalent negative refractive index optical element 3 is fixed on the shell 1, the equivalent negative refractive index optical element 3 is positioned at the display port 12, and an included angle is formed between the light emitting direction of the display module 2 and the mirror surface of the equivalent negative refractive index optical element 3. The mirror surface of the equivalent negative refractive index optical element 3 refers to the surface of the equivalent negative refractive index optical element 3, and both side surfaces of the equivalent negative refractive index optical element 3 are parallel to each other.

Referring to fig. 2 and 3, in the present embodiment, the equivalent negative refractive index optical element 3 may be a plate lens. When the illuminant emits light from one side of the plate lens towards the plate lens, the plate lens can refocus the divergent light in the air, so that an aerial image which does not need medium bearing is formed in the air at the other side of the plate lens.

In this way, after the display module 2 emits light to the optical element 3 with equivalent negative refractive index, negative refraction occurs when the light passes through the optical element 3 with equivalent negative refractive index, and the light after negative refraction can pass through the display port 12 to enter the outside of the housing 1, and form a floating real image in the air outside the housing 1.

The region where the floating real image is located forms an imaging region 13, the imaging region 13 is located outside the housing 1, and the imaging region 13 and the display module 2 are distributed in mirror image with the equivalent negative refractive index optical element 3
