Description

Technical Field

[0001] This utility model relates to the field of teleprompter technology, specifically a suspended stage teleprompter device. Background Technology

[0002] Teleprompters display text on a scrolling screen, helping users speak or sing fluently without frequently looking down at their notes. They are commonly used in news broadcasts, speeches, and concerts, enhancing the professionalism and naturalness of the performance. Modern teleprompters are mostly software-based, supporting operation on mobile phones or computers and compatible with various text formats.

[0003] In the prior art, the authorized announcement number CN213159411U discloses a novel stage teleprompter. The novel stage teleprompter includes a main body, which includes a housing and a display screen disposed at the front end of the housing. The housing is provided with a carrying handle, and the display screen is tilted. The side wall of the housing is also provided with a wire hole, through which an audio cable and a video cable are respectively connected to the display screen and the host on the main body.

[0004] During a performance, singers often move frequently to different positions on stage to better interact with the audience and enhance the stage effect. However, teleprompters are typically fixed in the center of the stage for easy viewing most of the time. But when singers move to the edges of the stage, distance and angle limitations make it difficult to clearly see the text displayed on the teleprompter screen, potentially affecting the fluency and accuracy of their performance. Therefore, a suspended stage teleprompter device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a suspended stage prompting device to solve the problems in the prior art.

[0021] 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.

[0022] Example 1: As Figure 1 and Figure 2As shown, this utility model provides a technical solution for a suspended stage teleprompter device, including a slide rail 1, a slider 3 slidably mounted on the slide rail 1, a slide plate 2 fixedly mounted on the slider 3, a teleprompter housing 4 fixedly mounted on the bottom of the slide plate 2, an adjustment mechanism 5 mounted on the teleprompter housing 4, and a screen assembly 6 mounted on the teleprompter housing 4.

[0023] Specifically, in use, the slide rail 1 is first fixedly installed above the stage. Then, the teleprompter is mounted on the slider 3 on the slide rail 1 using the slider 3, thus suspending the teleprompter on the stage. By using the adjustment mechanism 5 and the screen assembly 6 together, the position and tilt angle of the screen body 605 can be adjusted so that singers standing in different positions on the stage can observe the screen body 605, improving the effectiveness of the teleprompter.

[0024] Example 2: Figure 2 and Figure 3 As shown, the adjustment mechanism 5 includes a rack 501 fixedly installed at the bottom of the slide rail 1 and a movable shaft 504 rotatably installed on the teleprompter housing 4. Gears 502 are fixedly installed at both ends of the movable shaft 504, and the gears 502 mesh with the rack 501. The adjustment mechanism 5 also includes a servo motor 507 fixedly installed on one side of the teleprompter housing 4. The output end of the servo motor 507 is connected to a first electromagnetic clutch 506. The output end of the first electromagnetic clutch 506 is fixedly installed with a drive shaft 508, and the drive shaft 508 is perpendicular to the movable shaft 504. A first mounting bracket 505 is fixedly installed on the top of the teleprompter housing 4, and the drive shaft 508 is rotatably installed on the first mounting bracket 505. A bearing is installed on the teleprompter housing 4, and the movable shaft 504 is rotatably installed inside the teleprompter housing 4 through the bearing.

[0025] Specifically, when the first electromagnetic clutch 506 is engaged, the servo motor 507 starts and begins to operate, driving the drive shaft 508 to rotate via its power output. During rotation, the drive shaft 508 transmits rotational power to the movable shaft 504, causing it to rotate as well. The rotation of the movable shaft 504 drives the gear 502 to rotate synchronously. During rotation, the teeth of the gear 502 mesh with the teeth of the rack 501, rolling along the length of the rack 501. This rolling motion generates a horizontal thrust, forcing the teleprompter housing 4 to slide left and right on the horizontal plane. In this way, the left and right position of the teleprompter on the stage can be precisely adjusted, ensuring that the displayed content is accurately aligned with the performer's line of sight, thereby improving the smoothness and visual appeal of the stage performance.

[0026] Example 3: Figure 2 and Figure 4As shown, the screen assembly 6 includes a mounting shaft 606 rotatably mounted inside the teleprompter housing 4 and a second mounting bracket 603 fixedly mounted inside the teleprompter housing 4. A drive shaft 601 is rotatably mounted on the second mounting bracket 603. A resistance rubber ring 604 is fixedly mounted inside the second mounting bracket 603. A second electromagnetic clutch 602 is mounted on the drive shaft 601 and is fixedly mounted inside the teleprompter housing 4. The screen body 605 is fixedly mounted on the mounting shaft 606. The second mounting bracket 603 has mounting holes, and the drive shaft 601 is rotatably mounted on the second mounting bracket 603 through the mounting holes. Helical gears 503 are fixedly mounted on the movable shaft 504, the drive shaft 508, the drive shaft 601, and the mounting shaft 606.

[0027] Specifically, when the second electromagnetic clutch 602 is engaged, the servo motor 507 drives the drive shaft 601 to rotate. During this rotation, the drive shaft 601 drives the mounting shaft 606 to rotate as well. The rotation of the mounting shaft 606 is then transmitted to the connected screen body 605, causing it to rotate as well. In this way, the tilt angle of the screen body 605 is effectively adjusted. This ensures that the singer can clearly observe the content displayed on the screen body 605 regardless of their position on stage, greatly improving the teleprompter's usability and ensuring the singer can read and sing the lyrics more smoothly during the performance, further enhancing the overall performance quality and entertainment value.

[0028] Working Principle: First, the slide rail 1 is fixedly installed above the stage. Then, the servo motor 507 is started. When the first electromagnetic clutch 506 is engaged, the servo motor 507 drives the drive shaft 508 to rotate. The drive shaft 508 then drives the movable shaft 504 to rotate, which in turn drives the gear 502. As the gear 502 rotates, it rolls along the rack 501, forcing the teleprompter housing 4 to slide left and right, thus adjusting the teleprompter's left and right position on the stage. When the second electromagnetic clutch 602 is engaged, the servo motor 507 drives the transmission shaft 601 to rotate. The transmission shaft 601 then drives the mounting shaft 606 to rotate, which in turn drives the screen body 605 to rotate, thus adjusting the tilt angle of the screen body 605 so that performers at different positions on the stage can observe it, improving the teleprompter's effectiveness.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
