Description

Technical Field

[0001] The utility model relates to the technical field of audio, and more specifically to a multimedia audio device with a dustproof structure. Background Art

[0002] With the continuous development of society and the continuous progress of science, multimedia teaching methods are becoming more and more popular. Multimedia teaching refers to a teaching method that, in the teaching process, is based on the teaching objectives and the characteristics of the teaching objects, through teaching design, reasonable selection and combination with modern teaching tools. Teaching audio is also needed during teaching.

[0003] Patent application number CN202220794331.7 A multimedia teaching audio device with a dustproof structure includes an audio body, a heat dissipation hole and an adjustment key. A heat dissipation hole is provided on one side of the audio body, an adjustment key is provided at the front end of the audio body, a protective structure is provided at the four corners of the audio body, a convenient structure is provided at the top of the audio body, an air inlet is provided at the rear end of the audio body, and a dustproof mechanism is provided inside the rear end of the audio body. The protective structure includes a protective plate, a card block and a card slot. The card slot is provided inside the four corners of the audio body, and a card block is provided inside the card slot. The utility model is provided with a dustproof mechanism. When the audio body is used, in order to prevent dust from entering the interior of the audio body through the air inlet, the dust can be filtered by using a dustproof plate, a slot and a dustproof net, thereby reducing the amount of dust entering the interior of the audio body, thereby improving the dustproof effect.

[0004] This structure achieves dust filtering by inserting a dustproof net into a slot at the top of the speaker body, thereby achieving a dustproof effect. However, in actual use, dust will adhere to the surface of the filter, and the slot needs to fit the filter. Therefore, lifting the filter upward when cleaning the filter will cause dust to fall off or even enter the inside of the speaker. In addition, speakers are used in many scenarios, and in many cases they need to be placed in a high place for sound amplification. If there is no suitable place to place them, it will affect the use of the speakers. Therefore, professionals in this field provide a multimedia audio device with a dustproof structure to solve the above-mentioned problems. Utility Model Content

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0022] See also Figures 1 to 4 In the utility model, a multimedia audio device with a dustproof structure includes a multimedia audio body 1 and a heat dissipation slot 2. The heat dissipation slot 2 is opened on the back of the multimedia audio body 1. The back of the multimedia audio body 1 is detachably connected with two limit shafts 3. The heat dissipation slot 2 is located on the opposite side of the two limit shafts 3. A filter plate 4 is arranged on the back of the multimedia audio body 1. The filter plate 4 is located on the back of the heat dissipation slot 2. Both sides of the filter plate 4 are respectively slidably connected to the inside of the two limit shafts 3. One side of the back of the limit shaft 3 is fixedly connected with a mounting seat 5. The inside of the mounting seat 5 is connected to the limit shaft 3. The interior of the shaft 3 is connected, a pressure strip 6 is slidably connected to the inner wall of the limit shaft 3, an adjusting rod 7 is rotatably connected to the mounting seat 5, a sleeve 8 is threadedly connected to the adjusting rod 7, the sleeve 8 is slidably connected to the inner wall of the mounting seat 5, and the other end of the sleeve 8 is fixedly connected to the pressure strip 6, a mounting ring 9 is detachably connected to the multimedia audio body 1, a synchronizing ring 10 is slidably connected to the bottom of the mounting ring 9, and a uniformly distributed supporting shaft 11 is fixedly connected to the bottom of the synchronizing ring 10, an adjusting screw 16 is rotatably connected to the top of the mounting ring 9, and the synchronizing ring 10 is threadedly connected to the adjusting screw 16;

[0023] The bottom of the mounting ring 9 is fixedly connected with uniformly distributed guide posts 12, and the mounting ring 9 is slidably connected to the inner wall of the guide posts 12;

[0024] The backs of the mounting ring 9 and the synchronizing ring 10 are both provided with through grooves 13, and the through grooves 13 are located at the top of the heat dissipation grooves 2;

[0025] The mounting ring 9 and the limiting shaft 3 are both connected with screw hole ear plates for connecting with the multimedia audio body 1 .

[0026] In actual use, the user slides the filter plate 4 into the two limit shafts 3 so that the filter plate 4 blocks the multiple groups of heat dissipation slots 2. There are tiny holes on the surface of the filter plate 4 to achieve air circulation, but dust in the air will be blocked by the filter plate 4. Then the user rotates the adjustment rod 7, and the sleeve 8 threadedly connected to the adjustment rod 7 begins to move inside the mounting seat 5, thereby pushing the pressure strip 6 to move toward the side of the filter plate 4 until the side of the filter plate 4 is compacted to limit the filter plate 4. If there is dust on the surface of the filter plate 4, the user can reversely rotate the adjustment rod 7 to make the pressure strip 6 6 is separated from the filter plate 4, and the user just needs to pull the filter plate 4 upwards. In actual use, the multimedia audio body 1 is placed stably for broadcasting. The user can lift the multimedia audio body 1 and rotate the adjusting screw rod 16, and the synchronous ring 10 threadedly connected to the adjusting screw rod 16 begins to move downward, and the multiple groups of support shafts 11 move downward synchronously. After adjusting to the appropriate position, the user puts down the multimedia audio body 1, and the support shaft 11 contacts the ground or the table, thereby changing the height of the audio, which will change the operation and broadcasting effect.

[0027] In the utility model, a filter plate 4 limited by a limit shaft 3 is provided on the back of the multimedia audio body 1 to filter the airflow entering the heat dissipation slot 2, thereby preventing dust from entering the audio system and achieving dust prevention. The filter plate 4 side is pressed by an adjusting pressure strip 6, and the filter plate 4 is limited while the sealing of the filter plate 4 side is improved to improve the dust prevention effect. At the same time, the height of multiple groups of support shafts 11 can be adjusted by adjusting the screw rod 16 in conjunction with the synchronization ring 10, so that the height of the audio system can be changed in actual use, which is convenient for operation and can also provide different broadcasting effects to meet different needs.

[0028] See also Figure 4 , wherein: a limiting groove 14 is provided on the inner wall of the limiting shaft 3 , and the pressure strip 6 is slidably connected to the inner wall of the limiting groove 14 .

[0029] In the utility model, when the pressure strip 6 moves, the limit groove 14 will limit the pressure strip 6, so that the pressure strip 6 is always located inside the support shaft 11 to keep stable movement, thereby improving the squeezing effect on the filter plate 4.

[0030] See also Figure 1 and 2 , wherein: the bottom end of the support shaft 11 is fixedly connected with a support plate 15, and the bottom of the support plate 15 is provided with evenly distributed anti-slip bumps.

[0031] In the present invention, when the support shaft 11 moves downward, the support plate 15 will contact the ground. The support plate 15 increases the contact area between the support shaft 11 and the ground or table top, thereby improving stability. The anti-slip protrusions can increase friction to prevent the multimedia audio body 1 from moving.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
