[0058] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0059] Example 1:

[0060] like Figures 1-13As shown: The mobile KTV karaoke booth includes a base, enclosure panels, and a roof. One side of the base has a stone-plastic base 2, a rock wool layer 3, and a cement fiberboard 20, assembled sequentially from top to bottom. Each of the four corners of the enclosure panels has a support column 5, and one side of each support column 5 has a wall panel. This wall panel is composed of an aluminum-plastic panel 50, a core rock wool layer 30, a rock wool layer 3, and a corrugated board 51, arranged sequentially from indoors to outdoors. One side of the roof has a Great Wall aluminum-plastic panel 7, a rock wool layer 3, and a core rock wool layer 30. The aluminum-plastic panel 50, the roof is provided with a Great Wall aluminum-plastic panel 7, rock wool layer 3, sandwich rock wool layer 30 and aluminum-plastic panel 50 are combined from top to bottom; the mobile KTV singing bar is provided with a control center touch screen 8, color lights, TV 80, song selection touch screen 81, speaker 82, built-in air conditioner 83, phantom mirror 84, coffee table 85, sofa 86. The color lights include five-finger lights 9 and moving head lights 90. The rock wool layer 3 provided in its base, surrounding panels and roof is an opaque material, which has the function of preventing light from passing through, and the rock wool layer 3 has the effect of sound insulation, thereby increasing the user's singing atmosphere experience;

[0061] Rock wool layer 3 is made of natural basalt or diabase as the main raw material. After being melted at high temperature (about 1500℃), it is made into fibers by centrifugation. Then, a small amount of binder (such as phenolic resin) and water-repellent agent are added and pressed into a board. The basalt fibers themselves are opaque and have a fine fiber diameter (usually 4-7μm) and are arranged randomly. However, rock wool layer 3 is provided in the base, surrounding panels and roof, which helps to form an opaque shape in the base, surrounding panels and roof, so as to prevent the light rays of the RGB lights from affecting pedestrians outside.

[0062] The sound insulation principle of rock wool layer 3 mainly relies on its porous fiber structure and material properties. It achieves noise reduction by absorbing, scattering, and damping sound wave energy. Rock wool consists of countless tiny mineral fibers (4-7 μm in diameter) interwoven to form a large number of micropores (porosity >90%). When sound waves enter the rock wool board, they are repeatedly refracted and rubbed within the pores, converting sound energy into heat energy. The elasticity of the rock wool fibers vibrates with the sound waves, but due to its high density and the presence of binders, the vibration is quickly suppressed, reducing sound wave reflection. The disordered distribution of rock wool fibers disrupts the direction of sound wave propagation, causing scattering and reducing the intensity of direct sound. Rock wool has a high surface density (typically 60-200 kg / m³). 3 The rock wool layer 3 effectively blocks the penetration of mid-to-high frequency sound waves; however, the rock wool layer 3 achieves the function of sound insulation.

[0063] like Figure 5As shown: The Phantom Mirror 84 is a type of glass that combines optical principles with special coating technology. The glass surface is coated with a special optical coating (such as a semi-transparent and semi-reflective film), which makes the glass have the characteristics of partial reflection and partial light transmission. It balances the superposition effect of real scenes and virtual images, and can produce the visual effect of superimposed virtual and real images and floating images. In addition, through the configuration of colorful lights, it can enhance the user's singing atmosphere experience.

[0064] The control center touch screen 8 is connected to the color lights, television 80, karaoke touch screen 81, speakers 82, indoor air conditioner 83, electrical box 1, electric door 6, door control touch screen 64, fresh air unit 61, exhaust fan 60, and outdoor air conditioner 62 via conduit. The control center touch screen 8 uses a built-in control module (existing technology). However, the control center touch screen 8 enables one-button control of the electrical appliances installed in the mobile KTV karaoke bar of this application.

[0065] The television set 80, the speaker 82 and the karaoke touch screen 81 are connected. The connection between the karaoke touch screen 81 and the television set 80 and the speaker 82 is such that the television set 80 can play the songs selected by the karaoke touch screen 81.

[0066] The connection between the indoor air conditioner 83 and the outdoor air conditioner 62 is an existing technology that helps to adjust the temperature inside the mobile KTV karaoke room.

[0067] The connection between the electric door 6 and the door control touch screen 64 mainly relies on signal transmission technology and wiring. However, the electric door 6 is the structure for opening and closing.

[0068] The combination of the fresh air unit 61 and the exhaust fan 60 is a ventilation device used for indoor and outdoor air exchange. Its core function is to filter outdoor air and send it into the room without opening the windows, while simultaneously exhausting indoor polluted air, thus achieving the effect of ventilation and purification.

[0069] Electrical box 1 is connected to the control center touch screen 8, colored lights, TV 80, karaoke touch screen 81, speakers 82, indoor air conditioner 83, electric door 6, door control touch screen 64, fresh air unit 61, exhaust fan 60, and outdoor air conditioner 62 via conduit, and has a structure for power supply.

[0070] The electrical box 1 is connected to the light strip 41 separately via a conduit. However, the start time can be controlled by a time controller (existing technology), which helps the light strip 41 of the mobile KTV to start at night, thereby enhancing the aesthetics of the mobile KTV.

[0071] like Figure 6As shown: The base is made of rock wool layer 3, and the cement front panel is equipped with a fixed base on the side. The bottom of the base is equipped with a fixed base or a wide support surface to lower the center of gravity, but increase the weight of the mobile KTV karaoke bar, which helps to improve the stability of the mobile KTV karaoke bar and reduce the impact of collisions or vibrations.

[0072] The fixed base has support bases 21 at the four corners. The bottom surface of the support bases 21 is provided with rubber pads and silicone anti-slip texture (not shown in the figure) to prevent the mobile KTV from sliding on smooth tabletops or floors.

[0073] A crossbeam 4 is provided on one side of the fixed base. There are multiple crossbeams 4. The crossbeams 4 bear the weight from the upper structure and transmit the force to the wall panel or support column 5, thus avoiding the problem of excessive local stress on the mobile KTV karaoke bar.

[0074] The fixed base includes a first crossbar 22 and a second crossbar 23. The support column 5 and one end of the wall panel are located on the first crossbar 22 and the second crossbar 23. The wall panel is provided with four pieces, and the wall panel is provided with an electric control door 6, an exhaust fan 60, a fresh air unit 61, an air conditioner outdoor unit 62 and a one-way mirror 63 respectively.

[0075] A door control touch screen 64 is provided on one side of its wall panel. The door control touch screen 64 is adjacent to the electric door 6, and a one-way mirror 63 is provided on one side of the electric door 6.

[0076] One-way mirror 63, also known as one-way perspective glass, is a special type of optical glass. Its core characteristic is that one side is transparent while the other side has a mirror effect. When the light is sufficient, most of the light is reflected by the mirror metal layer, creating a mirror effect. When the light is dim, the light reflected from the mirror side is stronger than the light from the transparent side, making it impossible for the observer to see the dark side. However, users inside the mobile KTV can observe problems outside through the one-way mirror 63, while pedestrians outside cannot observe problems inside the mobile KTV.

[0077] The bottom of the eaves block 70 is connected to the support column 5 and one end of the wall panel, while the roof is formed at the other end of the support column 5 and the wall panel. The side of the Great Wall aluminum composite panel 7 is located on the top of the eaves block 70, and the rock wool layer 3 and the sandwich rock wool layer 30 are located inside the eaves block 70.

[0078] like Figure 13 As shown: The top of the eaves block 70 is provided with a protruding support plate 700, which is connected to the frame of the Great Wall aluminum composite panel 7, which helps to improve the stability of the Great Wall aluminum composite panel 7 installation.

[0079] The bottom of the eaves block 70 is provided with a groove, which can be used to store the conduit installed in the mobile KTV karaoke booth;

[0080] The eaves block 70 has an inclined shape on one side, which helps the eaves block 70 to guide drainage;

[0081] Preferably, the gaps in the assembled mobile KTV karaoke booth can be filled with sound-insulating adhesive (not shown in the figure). Sound-insulating adhesive is a sealing material specially designed to block the transmission of sound. It improves the sound insulation effect by filling gaps and reducing vibration and sound bridging effect.

[0082] Example 2:

[0083] Preferably, a solar panel (not shown in the figure) can be installed on the roof. The solar panel, also known as a photovoltaic panel, is a module that directly converts sunlight into electrical energy. However, the mobile KTV karaoke bar of this application has an energy-saving and environmentally friendly structure.

[0084] Example 3:

[0085] like Figure 6 As shown: The fixed base is composed of a first crossbar 22 and a second crossbar 23. The end of the first crossbar 22 is bolted into the positioning block 220, and the height of the combination of the first crossbar 22 and the positioning block 220 is equal to the height of the second crossbar 23. However, the end of the combination of the first crossbar 22 and the positioning block 220 is connected to the end of the second crossbar 23. The top surface of the support base 21 is provided with the positioning block 220 and the second crossbar 4 respectively. A right-angle seat 210 is provided on one side of the top surface of the support base 21. The right-angle seat 210 is bolted to the first crossbar 22 and the second crossbar 23. However, the fixed base forms a rectangular shape, which helps to form a wide support surface at the bottom of the base, thereby reducing the impact of collisions or vibrations.

[0086] Example 4:

[0087] like Figure 6 As shown: the crossbeam 4 is in the shape of a grid, with a notch on one side. The combination structure of multiple crossbeams 4 is a riveted structure. However, the distribution of the crossbeams 4 forms a rivet array, which helps the crossbeams 4 avoid stress concentration and local deformation.

[0088] The base has a crossbeam 4, the ends of which are connected to one side of the first crossbar 22 and the second crossbar 23 by bolts;

[0089] The roof has a crossbeam 4 located on the side where the rock wool layer 3 and 30 meet. The crossbeam 4 on the roof and the crossbeam 4 on the base have the same structure.

[0090] The rock wool layer 3 inside the top layer is located in each grid-shaped cell;

[0091] The sandwich rock wool layer 30 is a composite building material, which is formed by bonding and pressing rock wool core material with metal or non-metal panels, and has the functions of heat preservation, fireproofing, sound insulation and structural strength.

[0092] Example 5:

[0093] like Figures 1-2 As shown: The first crossbar 22 and the second crossbar 23 have a protruding extension layer 40 on the other side. The wall panel and the support column 5 have an extension layer 40 on the outer side of the other end. The extension layer 40 has a head end 400 on one side and an end end 401 on the other side. The head end 400 and the end end 401 are both located on one side of the wall panel. The extension layer 40 of the base and the extension layer 40 of the wall panel and the support column 5 are connected by the head end 400 and the end end 401. The extension layer 40 has a groove on one side, and a light strip 41 is installed in the groove to enhance the aesthetics of the mobile KTV.

[0094] The first end 400 is adjacent to the electric door 6 and the door control touch screen 64. Its first end 400 is a protruding structure and has an arc shape, as shown in the reference. Figure 1 As shown, however, the electric door 6 and the door control touch screen 64, through the head end 400, have the function of shielding against rainwater;

[0095] Preferably, a hidden light strip 41 can be installed in the middle of the mobile KTV room to enhance the lighting effect of the mobile KTV room.

[0096] Example 6:

[0097] like Figure 11 As shown: A plurality of rubber pads 24 are provided on one side of the cement fiberboard 20. The cement fiberboard 20 is provided in multiple pieces. Rubber pads 2 are provided at the joints of the cement fiberboard 20 pieces. The cement fiberboard 20 and the rubber pads 2 can be assembled with sound insulation adhesive, which helps to form a whole from the cement fiberboard 20 pieces and facilitates the installation of the cement fiberboard 20.

[0098] One side of the rubber pad 24 is attached to one side of the crossbeam 4, and the gap formed by the rubber pad 24 and the crossbeam 4 can be assembled with sound insulation adhesive, thereby increasing the sound insulation effect at the joint of multiple cement fiberboards 20.

[0099] Example 7:

[0100] like Figure 5 As shown: The speaker 82 is connected to the roof frame by multiple support rods 820. However, the speaker 82 uses the support rods as a vibration transmission path to transmit the low-frequency vibration of the speaker cabinet to the mounting surface (such as a stage or support). By utilizing the resonance of a larger mass object (such as the ground), the low-frequency extension is enhanced (such as an electric guitar speaker amplifying the bass through a wooden stage).

[0101] Example 8:

[0102] like Figure 12As shown: Both ends of the TV set 80 are equipped with a karaoke touch screen 81, and the TV set 80 is mounted on one side of the enclosure with a wall mount 10. The wall mount 10 is connected to the frame of the karaoke touch screen 81, which helps to assemble the TV set 80 and the karaoke touch screen 81 into an integrated form.

[0103] The karaoke touchscreen 81 is located on top of the electrical box 1, which is triangular in shape. However, the triangular shape reduces the area occupied by the electrical box 1.

[0104] The assembly of the karaoke touchscreen 81 and the support plate 11 forms a triangular shape. However, the application of the triangle theorem helps to increase the stability of the karaoke touchscreen 81 installation.

[0105] Example 9:

[0106] like Figure 6 As shown: Multiple reinforcing rods 51 are provided between the support rods 5 and the roof, thereby increasing the stability of the roof.

[0107] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
