[0029] Embodiment one

[0030] In combination Figures 1 to 4 As shown in the figure, the embodiment provides a folding projection device, such as a projector, a projection display screen, etc., which comprises a light engine module 1, a horn module 2 and a hinge 3. Among them, the light engine module 1 is the core part of the device, mainly used for converting image signals into light signals and projecting onto the screen; the light engine module 1 is conductively connected to the horn module 2, which can input electrical signals into the horn module 2 and convert them into sound waves, in addition, the horn module 2 is provided with a horn mouth 21, when the electrical signals are converted into sound waves in the horn module 2, the sound waves can be diffused outward through the horn mouth 21, thereby providing the user with basic audio experience; the hinge 3 is used to realize the rotary connection of the light engine module 1 and the horn module 2, so that the light engine module 1 and the horn module 2 can form a foldable structure.

[0031] Through the above setting, the light engine module 1 and the horn module 2 can be independently set, on the one hand, the weight of the light engine module 1 can be reduced, and the internal structure complexity of the light engine module 1 can be reduced, thereby facilitating manufacturing and use; on the other hand, when the folding projection device is unfolded for use, the light engine module 1 can be away from the horn module 2, so that the heat dissipation surface of the light engine module 1 is increased, and the heat dissipation system in the light engine module 1 can effectively improve the heat dissipation effect of the heating components in the light engine module 1. In addition, after the folding projection device is folded, the light engine module 1 can be connected with the horn module 2, thereby reducing the volume of the entire device, facilitating carrying and storage.

[0032] Preferably, in the embodiment, the light engine module 1 and the horn module 2 are both square structures, compared with other shape structures such as circular, when the entire device is folded, the square structure of the light engine module 1 and the horn module 2 can further reduce the occupation of space volume, and when in use, the entire device can be placed in multiple postures, both vertically and horizontally, thereby greatly enhancing the use flexibility of the entire device.

[0033] Further, in the embodiment, referring to Figures 1 to 3 As shown in the figure, the horn mouth 21 is arranged on the circumferential side wall of the horn module 2, so that the horn mouth 21 can be exposed to the external environment after the light engine module 1 and the horn module 2 are folded, so that when the above-mentioned device needs to realize the projection requirement with a small volume, the horn mouth 21 can still be completely exposed to the external environment and output audio outward, thereby reducing the influence of the change of folding state.

[0034] Further, in the embodiment, the loudspeaker module 2 is provided with a plurality of loudspeaker openings 21 on both sides, so that the loudspeaker openings 21 on one side serve as the "left channel", and the loudspeaker openings 21 on the other side serve as the "right channel". This arrangement not only effectively improves the stereo sense, clarity and spatial sense of the audio, but also enables the user to obtain a more immersive and realistic sound experience. In addition, when the entire device is used in a side-up position, that is, the loudspeaker openings 21 on one side are blocked by the desktop, the loudspeaker openings 21 on the other side are still fully exposed to the external environment, so that the effect of transmitting audio outward can still be achieved.

[0035] It should be noted that in other parallel embodiments, referring to Figure 4 It should be noted that in other parallel embodiments, referring to

[0036] Further, the end of the loudspeaker module 2 is provided with a plurality of loudspeaker openings 21 on both sides, so that the effect of transmitting audio outward can still be achieved.

[0037] Optionally, in the embodiment, the hinge 3 includes a rotating block and a rotating shaft, one end of the rotating block is connected to the light machine module 1, and the other end is rotatably connected to the loudspeaker module 2 through the rotating shaft, so as to realize flexible connection between the light machine module 1 and the loudspeaker module 2. In addition, the hinge 3 has a simple structure, and can realize compact design of the light machine module 1 and the loudspeaker module 2, thereby saving the installation space of the device.

[0038] Specifically, the folding projection device provided in the embodiment further includes a power supply module 4, which is conductively connected to the loudspeaker module 2 and the light machine module 1, so that the loudspeaker module 2 and the light machine module 1 can normally operate. In addition, the hinge 3 provided in the embodiment is provided with two, the power supply module 4 is hingedly connected to the loudspeaker module 2 through one hinge 3, and the light machine module 1 is hingedly connected to the loudspeaker module 2 through the other hinge 3, so that the light machine module 1, the loudspeaker module 2 and the power supply module 4 are connected together to form a foldable structure with three folding layers.

[0039] Through the above arrangement, the adjustable angle of the light machine module 1 in the folding projection device can be more comprehensive, and the adjustable height is higher, thereby further improving the use flexibility. In addition, since the power supply module 4 is arranged independently of the light machine module 1, the power supply module 4 can reduce the influence on the heat dissipation of the light machine module 1, and compared with the traditional projector, the volume of the light machine module 1 can be further reduced, thereby further improving the use convenience and safety.

[0040] In other parallel embodiments, the opposite ends of the loudspeaker module 2 are provided with the above-mentioned loudspeaker ports 21, so as to further increase the number of sound wave output channels, so that the output sound is brighter and the adjustable range is wider. After folding, the light machine module 1 and the power supply module 4 can block the loudspeaker ports 21 at both ends of the loudspeaker module 2, so that all the loudspeaker ports 21 can be blocked.

[0041] Further, the power supply module 4 is a battery pack, so that the power supply module 4 can independently supply power to the light machine module 1 and the loudspeaker module 2, and no longer needs an external power supply, thereby further improving the portability and endurance of the entire folding projection device.

[0042] It should be noted that, due to the large weight of the power supply module 4, when the power supply module 4 and the light machine module 1 are arranged on the two sides of the loudspeaker module 2, the power supply module 4 can be supported and arranged on the desktop as a support of the entire device, thereby ensuring that the entire device is not easy to fall and ensuring the stability during use, and further allowing the light machine module 1 to be adjusted in a larger angle and height range to achieve the best projection effect.

[0043] Further, in the present embodiment, the thickness of the loudspeaker module 2 is less than the thickness of the power supply module 4 and the light machine module 1, so as to help reduce the weight of the entire device, make the entire device more portable and compact, and further reduce the space occupied by the entire device after folding.
