Description

Technical Field

[0001] The present invention relates to the technical field of audio equipment, and in particular to an open stereo interactive audio equipment. Background Art

[0002] The open stereo interactive audio equipment involved is needed in many occasions in modern society, such as conference rooms, concert halls, online teaching and training, libraries, exhibition halls and other places that require large-scale displays.

[0003] Among them, interactive devices are often set up in exhibition halls, theme education and other cultural, tourism or entertainment venues to provide tourists, audiences, etc. with relevant interactive experiences; there are many ways of interactive experience, such as audio, video playback, interaction, etc.

[0004] At present, audio interactive devices in certain places are mostly temporary settings and need to be dismantled after the exhibition or event. As a result, the interactive devices cannot take into account people of different heights and age groups. Therefore, this leads to interactive audio devices that can only be set up to take into account the height of adults, but cannot fully consider children of different ages.

[0005] For example, the normal height range for a 6-year-old boy is approximately between 117.7cm and 124.7cm, and the normal height range for a girl is approximately between 116.6cm and 123.4cm;

[0006] The height of 7-year-old boys is usually around 124.0cm to 131.8cm, and the height of girls is about 122.5cm to 130.2cm;

[0007] The normal height range for 8-year-old boys is about 130.1cm to 138.7cm, and the height of girls is generally 128.5cm to 137.2cm;

[0008] The height of a 9-year-old boy is usually between 135.4cm and 144.5cm, and the height of a girl is about 134.1cm to 143.3cm;

[0009] The normal height range for a 10-year-old boy is approximately 140.2cm to 150.9cm. Because girls may develop relatively earlier, their height is generally between 138.7cm and 148.8cm.

[0010] Therefore, temporary audio interactive equipment can only take into account a small number of people, and it does not take into account the problem of children and teenagers. Therefore, we specially propose an open stereo interactive audio device. Summary of the invention

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to Figures 1 to 4 , the present invention provides a technical solution:

[0046] An open stereoscopic interactive audio device includes an interactive audio device main body 1. U-shaped frames 101 are fixedly installed on both sides of the upper end surface of the interactive audio device main body 1 near the edges. Then, grooves 102 are opened on both side surfaces of the interactive audio device main body 1, and slide bars 103 are fixedly installed inside the grooves 102. Among them, the slide bar 103 is a cylindrical structure, as Figure 1 and Figure 2 shown.

[0047] As Figure 3As shown, a first adjusting plate 2 is slidably mounted on the circumferential surface of the sliding rod 103. Among them, both sides of one end of the first adjusting plate 2 away from the sliding rod 103 are rotatably mounted with adjusting rods 201. Among them, the position where the adjusting rod 201 and the first adjusting plate 2 are rotationally combined is rotationally connected by a strong damping device. Therefore, during use, when the adjusting rod 201 and the first adjusting plate 2 rotate, manual adjustment is required. Without external force drive, no rotation will occur between the adjusting rod and the first adjusting plate 2.

[0048] A first connecting rod 202 is rotatably mounted between the inner sides of the lower ends of the two adjusting rods 201. The position where the first connecting rod 202 and the adjusting rod 201 are rotationally connected is also rotationally connected by damping. Therefore, it can be ensured that no rotation will occur between the first connecting rod 202 and the adjusting rod 201 without external force drive. Two symmetric fixed connection blocks 203 are fixedly mounted on the circumferential surface of the first connecting rod 202. The lower end of the fixed connection block 203 is of a U-shaped structure and a first adjusting rod 204 is rotatably mounted inside. The lower ends of the two first adjusting rods 204 are both rotatably mounted with double-headed groove blocks 205. A double-headed threaded rod 206 is rotatably mounted on the two double-headed groove blocks 205 together. Among them, the right end of the double-headed threaded rod 206 is located outside the right double-headed groove block 205. Therefore, during use, when the double-headed threaded rod 206 rotates, the double-headed groove blocks 205 on the left and right sides can be gradually brought closer or farther away. Thus, the rotation angles of the two first adjusting rods 204 can be changed, and further, the height of the storage plate 208 for subsequent operations can be changed.

[0049] Second connecting rods 207 are fixedly mounted at the lower ends of the double-headed groove blocks 205. The inner sides of the lower ends of the two second connecting rods 207 are rotatably mounted with a storage plate 208 together. Among them, during use, as the inclination states of the two first adjusting rods 204 change, the second connecting rods 207 can drive the storage plate 208 to move up and down. Thus, during movement, the height of the storage plate 208 can accommodate children of different ages, and it will not cause adults to bend down.

[0050] Then there is the position where the second connecting rod 207 is rotatably connected to the storage plate 208. A strong damping rotation is adopted to prevent the storage plate 208 from rotating under the pressure of gravity after a child stands, ensuring the safety of the child. It should be noted that the same structure is provided on both the left and right sides of the interactive audio device main body 1. When the interactive audio device main body 1 tilts to the right, the storage plate 208 on the right side can perform operations. Also, during the non-use process, the adjusting rod 201 fits against the outer side of the interactive audio device main body 1, and then the first connecting rod 202 is rotated so that the first connecting rod 202 can drive the fixed connecting block 203. The fixed connecting block 203 drives the first adjusting rod 204, the first adjusting rod 204 drives the double-headed groove block 205, and the double-headed groove block 205 drives the second connecting rod 207 and the double-headed threaded rod 206 to rotate synchronously, thereby being located on the lower end surface of the interactive audio device main body 1. Moreover, when the second connecting rod 207 drives the storage plate 208 to rotate, the storage plate 208 is rotated according to the situation to prevent the storage plate 208 from colliding with the subsequent structure and ensuring the safety of the structure.

[0051] A load-bearing seat 3 is provided below the interactive audio device main body 1. A column 301 with an approximately rectangular structure is fixedly installed at the center of the upper end surface of the load-bearing seat 3. Two sliding cavities 302 are opened on the inner bottom wall of the top of the column 301, as Figure 4 and Figure 6 shown; secondly, two knobs 303 are rotatably installed on the outer side of the column 301, and a main bevel gear 304 is fixedly installed inside the sliding cavity 302 at the inner side of the knob 303. Among them, the knob 303 can drive the main bevel gear 304 to rotate. A secondary bevel gear 305 is rotatably installed on the inner bottom surface of the sliding cavity 302, and the secondary bevel gear 305 meshes with the main bevel gear 304. Therefore, when the main bevel gear 304 rotates, it can drive the secondary bevel gear 305 to rotate.

[0052] A threaded rod 306 is fixedly installed at the center of the top of the secondary bevel gear 305. Therefore, the secondary bevel gear 305 will drive the threaded rod 306 to rotate synchronously; in addition, a matching lifting rod 307 is slidably installed inside the sliding cavity 302. The top of the lifting rod 307 is in a U-shaped structure, as Figure 6As shown, a threaded hole 308 matching the threaded rod 306 is provided from the inner bottom surface of the U-shaped structure to the lower end surface of the lifting rod 307. Through the threaded hole 308, the lifting rod 307 can be rotationally connected to the threaded rod 306. Secondly, two vertical sliding grooves are provided on the inner wall of the sliding cavity 302, and protrusions matching the sliding grooves protrude outward on the circumferential surface of the lifting rod 307. The protrusions are slidably installed inside the sliding grooves to limit the synchronous rotation of the lifting rod 307 with the threaded rod 306. Therefore, during use, when the threaded rod 306 rotates, under the action of the thread, the lifting rod 307 can move downward. Without the restriction of the sliding groove and the protrusion, the lifting rod 307 will rotate synchronously with the threaded rod 306, resulting in the inability to complete the subsequent operations. Secondly, an adjusting wheel 309 is rotatably installed inside the top of the lifting rod 307. When the adjusting wheel 309 moves upward, it can push one end of the adjusting seat 311 for the subsequent operation to lift, thereby being able to adjust the inclination of the interactive audio device main body 1.

[0053] On the upper end surface of the load-bearing seat 3, two mounting plates 310 are fixedly installed on both sides of the column 301, and the adjusting seat 311 is rotatably installed on the inner upper ends of the two mounting plates 3, as Figure 5 shown. Therefore, during use, as the lifting rod 307 moves, the adjusting wheel 309 can push one end of the adjusting seat 311 upward and the other end downward, thereby driving the interactive audio device main body 1 to adjust the angle to meet the requirements of different scenarios.

[0054] Four support rods 4 are fixedly installed at the position of the lower edge of the load-bearing seat 3, and rollers 401 are rotatably installed at the lower ends of the support rods 4. During use, under the action of the rollers 401, the load-bearing seat 3 can be moved in position, thereby being able to drive the interactive audio device main body 1 to move in position. Then, a dual-output drive motor 402 is fixedly installed inside the support rod 4, and first gears 403 are fixedly installed on the output shafts at both ends of the drive motor 402. Then, second gears 404 are rotatably installed at the positions of the outer edges of the support rods 4. The second gears 404 are meshed with the adjacent first gears 403, and limit frames 405 are fixedly installed on the end faces of the second gears 404 away from each other, as Figure 8 shown.

[0055] Therefore, during use, the output shaft of the drive motor 402 drives the first gear 403 to rotate. The first gear 403 drives the second gear 404 to rotate, and the second gear 404 drives the limit frame 405 to rotate synchronously. As a result, the limit frame 405 can contact the ground to support the load-bearing seat 3, thereby fixing and supporting the load-bearing seat 3. It should be noted that since the limit frame 405 needs to be rotated when it is not used later, a groove with a through structure is provided at a position on the outer side to the inside of the load-bearing seat 3 that matches the limit frame 405, so that the limit frame 405 can rotate, as Figure 7 shown.

[0056] Four cavity rods 5 are fixedly installed inside the load-bearing seat 3. At the upper and lower end faces inside the cavity rod 5, chute rods 501 are fixedly installed. A through groove 502 is provided from the inner side to the inside of the chute rod 501. Limit rods 503 are slidably installed inside the upper and lower chute rods 501. A spring 504 is fixedly installed between the outer ends of the two limit rods 503 and one end inside the chute rod 501. Moreover, adjustment plates 505 are fixedly installed at the outer ends of the two limit rods 503. The end of the adjustment plate 505 away from the limit rod 503 is slidably installed inside the through groove 502 and extends outside the through groove 502, as Figure 10 shown.

[0057] During use, the adjustment plate 505 drives the limit rod 503 to slide, and during the sliding process, the spring 504 is compressed, which facilitates the subsequent removal and installation of the connection block 506.

[0058] The connection block 506 is slidably installed inside the cavity rod 5. The structure of the connection block 506 is a trapezoidal structure, as Figure 9 shown. Pin holes 507 are provided on the upper and lower sides of its trapezoidal structure. Accordingly, the adjacent ends of the limit rods 503 can be slidably installed inside the pin holes 507 to fix the connection block 506, thereby ensuring the stability of the connection block 506.

[0059] Adjustment motors 508 are fixedly installed on the inner sides of the connection blocks 506. Connection plates 509 are fixedly installed on the output shafts at both ends of the adjustment motors 508. Vertical plates 510 are rotatably installed inside the ends of the connection plates 509 away from the connection blocks 506. And suction cups 511 are fixedly installed at the lower ends of the vertical plates 510.

[0060] During use, the adjustment motor 508 will cause the connecting plate 509 to rotate, and when the connecting plate 509 rotates, it will cause the vertical plate 510 to move up and down, so that the suction cup 511 can contact or separate from the ground. In addition, during use, the suction cup 511 serves to fix the roller 401, and then fix the load-bearing seat 3, thereby ensuring the fixation of the structure. The operation of the suction cup 511 is similar to the conventional manual suction cup 511 structure on the market. You only need to bend the rotating rod of the suction cup 511 to make the suction cup 511 fit tightly against the ground, thereby facilitating disassembly and quick fixation.

[0061] Working principle: First, turn the knob 303, the knob 303 will drive the main bevel gear 304 to rotate, the main bevel gear 304 drives the secondary bevel gear 305 to rotate, the secondary bevel gear 305 will drive the threaded rod 306 to rotate, the threaded rod 306 drives the lifting rod 307 to slide, the lifting rod 307 drives the adjusting wheel 309 to move upward, and then the adjusting seat 311 rotates, so that the interactive audio device body 1 can be rotated, thereby completing the tilting state.

[0062] The first adjustment plate 2 is rotated. After the first adjustment plate 2 is rotated, the adjustment rod 201 is rotated according to the actual situation, and then the first connecting rod 202 is rotated, so that the storage plate 208 can be convenient for children to stand.

[0063] The double-threaded rod 206 can be rotated according to the situation to rotate the first adjustment rod 204, thereby moving the storage plate 208 up and down, thereby completing the height adjustment.

[0064] Next, the driving motor 402 is started, and the output shaft of the driving motor 402 rotates the first gear 403 , the first gear 403 drives the second gear 404 , and the second gear 404 rotates the limiting frame 405 , and the lower end of the limiting frame 405 contacts the ground.

[0065] Start the adjustment motor 508, the output shaft of the adjustment motor 508 drives the connecting plate 509 to rotate, the connecting plate 509 drives the vertical plate 510 to move up and down, the vertical plate 510 drives the suction cup 511 to rotate, the suction cup 511 is in close contact with the ground, and then the staff turns the corresponding adjustment device to allow the suction cup 511 to be fixedly connected to the ground.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
