[0025] Please refer to Figure 1 - Figure 5 In this embodiment, a portable combined KTV projection device is provided, including a main box body 1, a projector 2, and a microphone. The left and right sides of the main box body 1 are respectively provided with a first box chamber 110 and a second box chamber 120 of an integral structure; an installation area 130 is provided between the first box chamber 110 and the second box chamber 120; the projector 2 is arranged in the installation area 130 and is detachably connected to the main box body 1; and the projector 2 is rotationally connected to the outer walls of the first box chamber 110 and the second box chamber 120 through a rotary damping member 3; the installation area 130 is transparent on the front and rear sides of the main box body 1; at least one speaker is provided in each of the first box chamber 110 and the second box chamber 120.
[0026] By separating the first box chamber 110 and the second box chamber 120 by using the installation area 130, on the one hand, the first box chamber 110 and the second box chamber 120 can at least achieve the sound box playing effect of the left and right channels by using the speakers provided therein. On the other hand, by using the space of the installation area 130 to arrange the projector 2, the sound box and the projector 2 of this device are integrated, which is convenient for users to carry and use.
[0027] In addition, by using the detachable connection between the projector 2 and the main box body 1 and the fact that the installation area 130 is transparent on the front and rear sides of the main box body 1 without blocking the light projection of the lens of the projector 2, when the lens of the projector 2 faces the horizontal direction, it can be rotated to be the same as or opposite to the front-facing direction of the main box body 1. Then, the position of the whole device arranged by the user in the space is more flexible to meet the need of freely adjusting the front and back directions, ensuring the correct direction and effect of the sound source and improving the user experience.
[0028] Moreover, in combination with the rotary damping member 3, after the user adjusts the angle of the projector 2 relative to the main box body 1, it stops rotating and can directly be positioned at the adjusted angle for holding, avoiding using additional tools for locking; the projection angle of the projector 2 can be freely adjusted from 0° to 135°.
[0029] The main box 1 has a built-in control system board, and the microphone is wirelessly connected to the control system board. After the microphone receives the sound, it can be amplified and played by the speakers in the first box chamber 110 and the second box chamber 120, so that the user can sing karaoke.
[0030] Please refer to Figure 1 and Figure 3 , including a lifting mechanism connected to the main box 1 and the projector 2, and the height of the projector 2 relative to the main box 1 can be adjusted by the lifting mechanism.
[0031] Please refer to Figure 1 and Figure 3 The lifting mechanism includes a guide slide 410, a slide 420 slidably connected to the guide slide 410, and a locking member (not shown) provided on the slide 420; the relative position of the slide 420 relative to the guide slide 410 is adjusted by the locking member; the slide 420 is provided with a connecting portion 421 connected to the rotation damping member 3; the guide slide 410 is arranged in the installation area 130 and connected to the main box 1.
[0032] In some embodiments, the locking member is a hand screw that passes through the slide 420. The slide 420 is provided with a screw hole corresponding to the hand screw. By screwing the hand screw, the slide 420 can be kept fixed relative to the guide slide 410, or can slide relatively.
[0033] Preferably, the length direction of the guide slide 410 is parallel to the height direction.
[0034] Please refer to Figure 1 and Figure 3 , the main box body 1 is made of elastic material; when the outer walls of the first box chamber 110 and the second box chamber 120 of the installation area 130 are pressed, the first box chamber 110 and the second box chamber 120 can be relatively far away.
[0035] The main box body 1 can be made of plastic, and when the first box chamber 110 and the second box chamber 120 are pushed and moved relatively away, the space of the installation area 130 is expanded, and the projector 2 can be easily disassembled and connected to the main box body 1. After the external force is removed, the main box body 1 automatically returns to its original state.
[0036] Please refer to Figure 1 and Figure 3 When the rotation damping member 3 is a damping bearing, the connecting portion 421 is a shaft column corresponding to the shaft hole of the damping bearing, and preferably, the end of the shaft column is rounded.
[0037] Please refer to Figure 1 and Figure 3 , including a vibration isolator (not shown), and the rotation damping member 3 is connected to the outer walls of the first chamber 110 and the second chamber 120 through the vibration isolator.
[0038] In some embodiments, the vibration isolation member is a magnetic levitation device that generates magnetism from electricity. During operation, the projector 2 is not directly connected to the main cabinet 1 through the magnetic levitation device. In this way, when the speakers in the first chamber 110 and the second chamber 120 vibrate during operation, they will not drive the projector 2 to vibrate together, avoiding jitter in the projected image output by the projector. In addition to the magnetic levitation device, the vibration isolation member can also be other forms of vibration isolation devices in the prior art, which play a role in isolating or reducing vibration conduction.
[0039] Please refer to Figure 1 and Figure 3 , including a separation frame 5, the separation frame 5 is provided with a mounting portion 520 connected to the rotary damper 3; the main cabinet 1 is provided with an avoidance hole 140 corresponding to the separation frame 5; after the projector 2 is disassembled from the main cabinet 1, it is connected to the separation frame 5 and is mounted on the installation area 130.
[0040] The structure of the mounting portion may be the same as the structure of the connecting portion 421.
[0041] After confirming the placement position of the device, disconnect the connection between the projector 2 and the main cabinet 1 by disassembly. The lower support portion 510 of the separation frame 5 is located in the avoidance hole 140 and does not contact the main cabinet 1. The projector 2 is connected to the separation frame 5, and also obtains the characteristic of not having a direct connection with the main cabinet 1. In this way, when the speaker vibrates during operation, it will not drive the projector 2 to vibrate together, resulting in jitter in the projected image output by the projector 2.
[0042] Preferably, the separation frame 5 is a folding telescopic frame; the main cabinet 1 is provided with a receiving groove (not shown) for receiving the separation frame 5.
[0043] Please refer to Figure 1 and Figure 3 , including a bottom support plate 150, the first chamber 110 and the second chamber 120 are connected as a whole through the bottom support plate 150; and the first chamber 110 and the second chamber 120 are detachably connected to the bottom support plate 150.
[0044] Through this design, when some components of the device need to be maintained, only the parts that need to be maintained need to be disassembled, rather than carrying the whole machine, which provides convenience during the maintenance and transportation process.
