Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4 As shown, an easy-to-install sound-permeable screen includes a base 100, on which a mounting box 101 is fixedly connected. The mounting box 101 has a mounting groove 102, and a fixing frame 201 is fixedly connected to the mounting groove 102 via a snap-fit ​​mechanism. An LED display screen 202 is fixedly connected to the fixing frame 201. The LED display screen 202 has multiple sound-permeable holes 203 in the middle. The mounting box 101 contains a cleaning unit for preventing the sound-permeable holes 203 from becoming clogged and a transmission component for driving the cleaning unit. The snap-fit ​​mechanism allows workers to easily fix the LED display screen 202 onto the mounting groove 102 of the mounting box 101. When the LED display screen 202 is damaged, the snap-fit ​​mechanism allows workers to easily remove the LED display screen 202. When the sound-permeable holes 203 become clogged due to prolonged use, the cleaning unit can unclog the sound-permeable holes 203 to ensure the audience's listening experience.

[0025] In this embodiment, as Figure 2 and Figure 3As shown, the latching mechanism includes two fixed latching blocks 301 and two movable latching blocks 302. The two fixed latching blocks 301 are fixedly connected to the lower end of the mounting box 101. The lower side of the fixing frame 201 is provided with a first latching groove 303 corresponding to the fixed latching blocks 301. The two movable latching blocks 302 are slidably connected in the sliding grooves 304 on the mounting box 101. A track 305 is provided between the two sliding grooves 304. A limiting groove 306 is provided in the middle of the track 305. A sliding connection button 307 is provided. A connecting rope 308 is fixedly connected between the two movable blocks 302. The connecting rope 308 passes through the track 305 and through the button 307. A spring 309 is provided in the slide groove 304. One end of the spring 309 is fixedly connected to the inner wall of the slide groove 304, and the other end of the spring 309 is fixedly connected to the movable block 302. The upper side of the fixing frame 201 is provided with a second slot 310 corresponding to the movable block 302. When the LED display screen 202 is... During installation, first, the fixing block 301 is inserted into the first slot 303. Then, the LED display screen 202 is pushed. The fixing frame 201 first pushes the movable block 302 back into the slide groove 304 and compresses the spring 309. When the LED display screen 202 is in place, under the action of the spring 309, the movable block 302 pops out of the slide groove 304 and is inserted into the second slot 310, thus completing the fixed installation of the LED display screen 202. When it is necessary to disassemble the LED display screen 202... Press button 307. Button 307 drives the connecting rope 308 to retract into the limiting groove 306. The connecting rope 308 pulls the movable block 302 back into the slide groove 304 and compresses the spring 309. The movable block 302 disengages from the second slot 310, so that the fixation at the upper end of the LED display screen 202 is removed, and the LED display screen 202 can be rotated outward. Then lift the LED display screen 202 to disengage the fixing block 301 from the first slot 303, thus completing the disassembly of the LED display screen 202.

[0026] In one embodiment, such as Figure 2 and Figure 4 As shown, the cleaning unit includes two fixed frames 401, which are respectively fixedly connected to the inner walls on both sides of the mounting box 101. Two guide rods 402 are fixedly connected to the two fixed frames 401 respectively. Sliding blocks 403 are slidably connected to the outer ends of the two guide rods 402. A connecting plate 404 is fixedly connected between the two sliding blocks 403. Multiple ejector pins 405 are fixedly connected to the side of the connecting plate 404 near the sound-permeable hole 203. A transmission component is provided on the side of the sliding block 403. When the sound-permeable hole 203 is blocked due to long-term use, the sliding block 403 moves along the guide rods 402, and the ejector pins 405 push into the sound-permeable hole 203 to push out the dust in the sound-permeable hole 203, ensuring the transparency of the sound-permeable hole 203 and the audience's listening experience.

[0027] In one embodiment, such as Figure 4 As shown, the transmission component includes a motor 501, which is fixedly connected to the upper end of the fixed frame 401. The output end of the motor 501 is fixedly connected to one end of the first rotating rod 502. The other end of the first rotating rod 502 is rotatably connected to one end of the second rotating rod 503. The other end of the second rotating rod 503 is rotatably connected to the sliding block 403. When the motor 501 is started, the motor 501 drives the first rotating rod 502 to rotate. The first rotating rod 502 pulls the sliding block 403 along the guide rod 402 to move back and forth through the second rotating rod 503, thereby thoroughly cleaning the sound-permeable hole 203.

[0028] In one embodiment, such as Figure 4 As shown, the diameter of the ejector pin 405 is smaller than the diameter of the sound-permeable hole 203, so that the ejector pin 405 can be inserted into the sound-permeable hole 203 to clean the sound-permeable hole 203.

[0029] In one embodiment, such as Figure 4 As shown, a support plate 600 for mounting the speaker is fixedly connected in the mounting box 101, so that the sound comes out from the back of the LED display screen 202, giving the audience the best viewing experience.

[0030] In one embodiment, such as Figure 4 As shown, the number of the ejector pins 405 and the sound-permeable holes 203 are the same, and their positions correspond one-to-one, so that each sound-permeable hole 203 is thoroughly cleaned.

[0031] In one embodiment, such as Figure 1 As shown, the lower end of the base 100 is fixedly connected to an anti-slip pad 700 to prevent the acoustic screen from tipping over.

[0032] The above embodiment discloses an easy-to-install acoustically transparent screen. When installing the LED display screen 202, first, the fixing block 301 is inserted into the first slot 303. Then, the LED display screen 202 is pushed, and the fixing frame 201 pushes the movable block 302 back into the slide groove 304, compressing the spring 309. When the LED display screen 202 is in place, under the action of the spring 309, the movable block 302 pops out of the slide groove 304 and inserts into the second slot 310, thus completing the fixed installation of the LED display screen 202. When it is necessary to disassemble the LED display screen 202, the button 307 is pressed. The button 307 drives the connecting rope 308 to retract into the limiting groove 306, and the connecting rope 308 pulls the movable block 302 back into the limiting groove 306. In the slide 304, the spring 309 is compressed, and the movable block 302 disengages from the second slot 310, causing the upper part of the LED display screen 202 to be removed, thus allowing the LED display screen 202 to be rotated outwards. Then, the LED display screen 202 is lifted up, causing the fixed block 301 to disengage from the first slot 303, thus completing the disassembly of the LED display screen 202. When the sound-permeable hole 203 becomes clogged after prolonged use, the motor 501 is started. The motor 501 drives the first rotating rod 502 to rotate. The first rotating rod 502 pulls the sliding block 403 along the guide rod 402 to move back and forth through the second rotating rod 503. The ejector pin 405 pushes into the sound-permeable hole 203 to push out the dust in the sound-permeable hole 203, ensuring the transparency of the sound-permeable hole 203 and the audience's listening experience.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
