Description

Technical Field

[0001] The present invention relates to the technical field of interactive teaching, in particular to a music teaching demonstration device. Background Art

[0002] In the current field of quality-oriented education, extracurricular interest tutoring has become a crucial component in cultivating students' comprehensive qualities. This is particularly true in the field of musical instrument instruction, where traditional face-to-face instruction suffers from numerous technical flaws. In a one-to-many teaching format, students are often required to gather around the podium to observe the teacher's detailed performance techniques. This observation method has significant technical limitations. First, due to visual obstructions and limited viewing distance, students in the back row struggle to clearly observe key details such as the teacher's hand posture and fingering changes. Second, the dense crowding creates chaos in the classroom, impacting teaching efficiency.

[0003] A more prominent technical problem is that when students return to their seats to practice imitation, they often encounter problems such as deformed movements and incorrect techniques due to poor early observation. The existing teaching system lacks an effective real-time monitoring and feedback mechanism, making it difficult for teachers to obtain each student's practice data in a timely manner and unable to provide precise guidance based on individual differences. The shortcomings of this teaching model directly lead to: (1) low student practice efficiency, and incorrect movements are difficult to correct after they become muscle memory; (2) insufficient teacher guidance and unreasonable allocation of teaching resources; and (3) difficulty in quantifying and evaluating the overall teaching quality.

[0004] While existing instrument teaching aids exist, they often focus on teaching specific techniques for a single instrument. They lack universal solutions for multi-instrument instruction and fail to effectively optimize the entire "observation-feedback-correction" process in group instruction. Therefore, there is an urgent need to develop a new instrument teaching system to address these technical shortcomings of traditional teaching models. Summary of the Invention

[0005] The main purpose of the present invention is to overcome the shortcomings of the existing technology and provide a music teaching demonstration device. This music teaching demonstration device integrates mechanical damping, intelligent display, pneumatic locking, and adjustable viewing angle design, effectively solving the shortcomings of traditional teaching equipment and improving the interactivity, visualization, and ease of operation of music teaching.

[0006] The technical solution adopted by the present invention to achieve its technical objectives is: a music teaching demonstration device, including a teaching cabinet, a damping mechanism is provided above the teaching cabinet, the damping mechanism includes a circular frame plate, a movable box is slidably connected to the interior of the circular frame plate, a toothed plate is connected through the interior of the movable box, both ends of the toothed plate are fixedly connected to the inner wall of the circular frame plate, and one side is meshed with a damping gear, and the damping gear is installed inside the movable box; The teaching cabinet and the damping mechanism are connected via a bracket assembly or directly. A circular frame is fixed above the teaching cabinet and internally slidably connected to the moving box via a slide rail and a first slider. The toothed plate is fixed to the inner wall of the circular frame at both ends, passes through the moving box, and meshes with the damping gear.

[0007] The mobile box is internally provided with a flip mechanism, comprising a flip plate, which is rotatably disposed within the mobile box. A first smart display screen and a second smart display screen are respectively disposed on two surfaces of the flip plate. The flip plate is rotatably connected to the mobile box via a shaft or hinge, and the double-sided display screens are respectively embedded on two surfaces of the flip plate.

[0008] The damping mechanism enables the mobile box to slide left and right, making it easy to adjust the position of the display screen; the toothed plate and damping gear provide movement resistance to ensure stability.

[0009] The flip mechanism switches the display mode through the double-sided display screen: the first smart display screen displays the student screen, and the second smart display screen displays the teacher's performance screen, enhancing the teaching interactivity.

[0010] Preferably, a damper is installed inside the damping gear to provide a damping feeling when the moving box moves.

[0011] The damping gear is mounted inside the moving box via a bearing or fixed shaft and meshes with the toothed plate. The damper provides controlled resistance to prevent the moving box from sliding, ensuring that the display remains stable in any position, facilitating adjustment of the teaching viewing angle.

[0012] Preferably, blocking plates are provided at the upper and left ends of the flip plate, the blocking plates are connected to the groove plates via a third spring, and the groove plates are fixed to the inner wall of the moving box.

[0013] The blocking plate is elastically connected to the groove plate via a third spring, which is welded or bolted to the inner wall of the moving box. The blocking plate limits the tilting angle of the flip plate, preventing excessive rotation; the third spring provides a reset force to ensure stable positioning after flipping.

[0014] Preferably, a bracket assembly is provided between the teaching cabinet and the damping mechanism, the bracket assembly comprises an inclined platform and a support plate, and a foldable shaping plate and a folding cloth are provided on one side of the support plate.

[0015] The ramp is fixedly connected to the circular frame and teaching cabinet, with the support plate embedded within the ramp. The shaping plate is hinged via folding cloth, forming a foldable structure. The support plate is used to hold teaching materials; the folding cloth and shaping plate can be unfolded to cover the support plate for dust protection, or folded to provide more space for storage.

[0016] Preferably, a return groove is provided inside the ramp platform, an annular pipe is installed in the return groove, and the annular pipe is connected to multiple conduits and gas cylinders; A push rod is slidably connected in the conduit, and the push rod is connected to the bottom of the conduit through a first spring; A piston rod is provided in the air cylinder, the piston rod is connected to a toggle rod, and the toggle rod extends out of the ramp platform.

[0017] The annular conduit is fixed within the circular groove and connected to the air cylinder via a connecting pipe. A push rod is elastically connected to the bottom of the conduit via a first spring. The piston rod within the air cylinder is fixed to the toggle lever. When the toggle lever is pushed, the air cylinder pumps air, causing the push rod to release the support plate. Once released, the air pressure returns, and the push rod presses against the support plate, locking it.

[0018] Preferably, the first smart display screen is connected to a camera, which is mounted on a circular frame; the second smart display screen is connected to a camera, which is mounted on a mobile box.

[0019] The camera is fixed to the top of the circular frame with a semi-rigid rod, and the camera is also fixed to the side of the mobile box with a semi-rigid rod. The camera captures the student's image and displays it on the first smart screen, while the camera records the teacher's actions and displays them on the second smart screen, realizing two-way teaching observation.

[0020] Preferably, the camera head and the video camera are mounted on the circular frame plate and the mobile box via a semi-rigid rod. The semi-rigid rod can adjust the angle of the camera head and the video camera to ensure the best shooting angle.

[0021] Preferably, the second intelligent display screen is connected to a projector for projecting teaching content, and the teacher's performance picture is magnified and displayed through the projector, so that students can watch and learn together.

[0022] Preferably, the flip plate is triangular in shape, with the side surfaces being equilateral triangles. The triangular structure saves space, has high stability when flipping, and facilitates rapid switching of the double-sided display screen.

[0023] This music teaching demonstration device uses a damping mechanism to achieve left and right movement and positioning of the display screen. The moving box slides in the circular frame through a slide rail and a first slider, and uses a toothed plate to engage with a damping gear with a damper to provide movement resistance; the triangular flip plate of the flip mechanism is embedded with a double-sided smart display screen, and the display mode is switched by pressing and flipping: the first smart screen is connected to the camera to display the student's image, and the second smart screen is connected to the camera to record and project the teacher's performance movements; the bracket assembly uses a pneumatic ejector and folding cloth to achieve rapid storage and dust-proof covering of the support plate, thereby realizing multi-angle observation, dynamic capture and flexible management of teaching aids in music teaching.

[0024] Compared with the prior art, the present invention has the following beneficial effects: This music teaching demonstration device uses a damping mechanism to achieve left-right sliding and stable positioning of the display screen. Combined with a flip-up design for the dual-sided smart display, teachers can quickly switch between display modes: the first smart screen displays students' images in real time, facilitating observation of student dynamics; the second smart screen, connected to a camera and projector, captures and amplifies the teacher's performance details in real time. This design addresses the limitations of traditional teaching methods, such as limited viewing angles and the poor observation efficiency caused by group observation. It significantly enhances teaching interactivity and demonstration clarity, while reducing the burden on teachers and the error rate of students.

[0025] This music teaching demonstration device features a damping mechanism that meshes a toothed plate with a damping gear, ensuring controlled resistance as the display moves. This allows the display to remain stable at any position, facilitating adjustments to the teaching perspective. The space-saving, stable flip-plate structure facilitates quick switching between two screens, balancing stability with ease of operation.

[0026] This music teaching demonstration device adopts a pneumatic push rod locking and folding cloth dust-proof design through the bracket assembly. The support plate can be quickly replaced or installed for use, which optimizes the placement of teaching materials and dust-proof efficiency and facilitates the management of teaching aids.

[0027] This music teaching demonstration device integrates mechanical damping, intelligent display, pneumatic locking and adjustable viewing angle design. The device is suitable for multi-instrument teaching scenarios. Through the comprehensive application of mechanical damping, intelligent display, pneumatic locking and other technologies, it significantly improves teaching efficiency and visualization level.

[0039] See also Figure 1-Figure 3 A music teaching demonstration device includes a teaching cabinet 5, on the top side of which music teaching equipment is placed. A damping mechanism 1 is provided above the teaching cabinet 5. The damping mechanism 1 includes a circular frame 101, a moving box 102, an observation port 1021, a first slider 103, a slide rail 104, a toothed plate 105, and a damping gear 106. The damping mechanism 1 includes a circular frame 101, a movable box 102 is slidably connected to the interior of the circular frame 101, a first slider 103 is fixedly connected to the top and bottom of the movable box 102, a slide rail 104 is slidably connected to one side of the first slider 103, and the slide rail 104 is fixedly connected to the inner wall of the circular frame 101. Through the arrangement of the first slider 103 and the slide rail 104, the movable box 102 can be slidably connected to the interior of the circular frame 101.

[0040] The interior of the moving box 102 is connected with a toothed plate 105, and both ends of the toothed plate 105 are fixedly connected to the inner wall of the circular frame plate 101, and one side of the toothed plate is connected with a damping gear 106, which is fixedly installed inside the moving box 102. A damper is installed inside the damping gear 106, so it has a certain damping effect; through the cooperation of the damping gear 106 and the toothed plate 105, the moving box 102 will not move arbitrarily or easily move, so that the moving box 102 has a certain damping feeling when moving.

[0041] Furthermore, in this embodiment, an observation port 1021 corresponding to the position of the smart display screen in the flip mechanism 2 is opened on one side of the mobile box 102; through the setting of the observation port 1021, the smart display screen of the flip plate 201 can be viewed.

[0042] Specifically, during use, the display screen of the flip plate 201 is moved left and right by the movement of the moving box 102, making it easier for people to use it in different positions. The toothed plate 105 and the damping gear 106 increase the damping feeling of the moving box 102. The damping mechanism 1 allows the display screen in the flip plate 201 to move left and right and then pause at any position, making it easier to move and increasing the adjustability and diversity of the overall structure. Example 2

[0043] See also Figure 1-Figure 3 On the basis of the above embodiment, in the music teaching demonstration device, a flip mechanism 2 is provided inside the damping mechanism 1, and the flip mechanism 2 includes a flip plate 201, a groove plate 202, a third spring 203 and a blocking piece 204.

[0044] The flip mechanism 2 includes a flip plate 201, which is arranged in a triangular shape and the side is arranged in an equilateral triangle. The flip plate 201 is rotatably connected to the inside of the moving box 102 in the damping mechanism 1; a display screen is embedded in the flip plate 201, and the display screen of the flip plate 201 can be viewed through the setting of the observation port 1021.

[0045] Blocking pieces 204 are provided at the upper and left ends of the flip plate 201. One end of the blocking piece 204 is movably connected to the groove plate 202. A third spring 203 is provided between the groove plate 202 and the blocking piece 204. The outer wall of one side of the groove plate 202 is fixedly connected to the inner wall of the movable box 102. The blocking piece 204 blocks the two edges of the flip plate 201 to prevent the flip plate 201 from rotating forward or reverse. The third spring 203 is used to reset the blocking piece 204.

[0046] Furthermore, in this embodiment, display screens are embedded inside two surfaces of the flip plate 201, and the two display screens are respectively set as a first smart screen and a second smart display screen. The first smart screen and the second smart display screen are smart electronic display devices such as tablet computers or all-in-one computers; the first smart display screen is electrically connected to a camera 7, and the camera 7 is directed towards the bottom of the podium and aimed at the students, and the image captured by the camera 7 is displayed in real time on the first smart display screen, which is mainly used to display the characters in the classroom and observe the dynamics of the students during class; the second smart display screen is electrically connected to a camera 8, and the camera 8 is directed to the music teaching equipment placed on the teaching cabinet 5, such as a piano or organ. When the teacher is playing, the camera 8 captures the action picture of the teacher operating the music instrument in real time to the second smart display screen. At the same time, the second smart display screen is electrically connected to a projector (not shown in the figure), and the picture is broadcast through the projector, so as to facilitate students to watch and learn.

[0047] Furthermore, in this embodiment, camera 7 is fixedly mounted on the top of circular frame 101 in damping mechanism 1, and camera 8 is fixedly mounted on the front sidewall of mobile box 102 in damping mechanism 1, and can move with the movement of mobile box 102. Cameras 7 and 8 both include semi-rigid rods, which connect and mount them to circular frame 101 and mobile box 102. The principle and material of the semi-rigid rods are the same as those of the flexible rods used in existing conference microphones, thereby facilitating the adjustment of the angles of cameras 7 and 8.

[0048] Specifically, when in use, images are collected through the camera 7 and uploaded to the first smart display screen in the flip board 201. The first smart display screen is used to display the images of people in the classroom in real time, which can avoid the problem of difficulty in observing students' dynamics during the teaching process.

[0049] When the smart display screen of the flip plate 201 needs to be flipped, press the lower edge portion of the flip plate 201 so that the flip plate 201 pushes open the blocking piece 204, so that the second smart display screen faces the observation port 1021. The second smart display screen uses the camera 8 to capture the action images of the teacher operating the musical instrument in real time, and is also used to connect to the projector to broadcast the images in the second smart display screen through the projector, which is convenient for students to watch and learn, thereby improving teaching efficiency.

[0050] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Example 3

[0051] See also Figure 1-Figure 2 On the basis of the above embodiment, the music teaching demonstration device is provided with a bracket assembly 3 between the teaching cabinet 5 and the damping mechanism 1, and the bracket assembly 3 includes a ramp 301, a support plate 302, a shaping plate 303, and a folding cloth 304; The ramp platform 301 is fixedly installed between the bottom of the circular frame plate 101 in the damping mechanism 1 and the top of the teaching cabinet 5. A support plate 302 is provided inside the ramp platform 301. The support plate 302 is used to place music teaching materials for class teaching. A shaping plate 303 is provided on one side of the support plate 302. There are multiple shaping plates 303, and they are kept flush with one side of the support plate 302. The multiple shaping plates 303 are connected on the side by folding cloth 304. The folding cloth 304 makes the multiple shaping plates 303 connected as a whole. One end of the folding cloth 304 is fixedly installed on the side inner wall of the connection between the ramp platform 301 and the support plate 302. The folding cloth 304 is used to cover the folding cloth 304 on the support plate 302 by pulling the shaping plate 303 when the support plate 302 is not in use.

[0052] Specifically, when the music teaching materials are placed on the support plate 302, the shaping plate 303 is pulled to one side so that the shaping plate 303 and the folding cloth 304 are folded at one end of the support plate 302, thereby displaying the support plate 302 for placing the music teaching materials; similarly, when the support plate 302 is not needed, the shaping plate 303 is pulled to the opposite side to pull the folding cloth 304 so that the folding cloth 304 covers the support plate 302, thereby covering the support plate 302 and avoiding dust.

[0053] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Example 4

[0054] See also Figure 4-Figure 6 On the basis of the above embodiment, in the music teaching demonstration device, the support plate 302 is fixedly mounted in the ramp platform 301, the ramp platform 301 has a return groove 4 formed inside, an annular pipe 401 is fixedly installed inside the return groove 4, one side of the annular pipe 401 is fixedly connected to a plurality of conduits 402, and the two ends of the other side are fixedly connected to the air cylinder 403 through the connecting pipe 404; The conduits 402 are evenly distributed around the annular pipe 401. An I-shaped push rod 6 is slidably connected to the interior of the conduit 402. One end of the push rod 6 is connected to the bottom of the conduit 402 via a first spring 601, and the other end is slidably connected to the bottom of the conduit 402. At the same time, one end of the push rod 6 is sealed against the inner wall of the conduit 402, and the other end forms a seal against the bottom of the conduit 402. A piston rod 405 is slidably and sealedly connected to the interior of the gas cylinder 403. The piston rod 405 is connected to the top of the gas cylinder 403 via a second spring 406. By pulling the piston rod 405, the second spring 406 is subjected to tension, and the gas cylinder 403 draws air into the annular pipe 401 through the connecting pipe 404. One end of the piston rod 405 is fixedly connected to a toggle rod 407 , and the toggle rod 407 passes through a toggle hole 408 provided inside the ramp platform 301 and is located outside.

[0055] Specifically, during use, the support plate 302 is fixedly mounted in the ramp platform 301. When the support plate 302 needs to be taken out from the ramp platform 301, the toggle rod 407 is pushed upward to overcome the pulling force of the second spring 406 to pull the piston rod 405, so that the air cylinder 403 draws air into the annular pipe 401 through the connecting pipe 404, thereby generating negative pressure in the annular pipe 401 and the conduit 402, and thus the push rod 6 is not affected by the air pressure. Under the action of the rebound force of the first spring 601, the push rod 6 is pushed upward, so that the lower end of the push rod 6 is separated from the side wall of the support plate 302.

[0056] When the support plate 302 needs to be installed into the ramp platform 301, the toggle rod 407 is released, so that it is naturally pulled by the second spring 406 and moves downward and reset inside the air cylinder 403, so that the air cylinder 403 is inflated, and the annular pipe 401 is inflated through the connecting pipe 404, and the annular pipe 401 and the conduit 402 are pressurized, so that the push rod 6 is affected by the pressurization, and the push rod 6 can overcome the force of the first spring 601, and the push rod 6 is pushed downward, thereby supporting the four sides of the support plate 302, so that the support plate 302 will not fall off the ramp platform 301.

[0057] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use.

[0058] The working principle and specific usage process of the music teaching demonstration device: The left and right movement and positioning of the display screen are achieved through the damping mechanism 1, wherein the moving box 102 slides in the circular frame plate 101 through the slide rail 104 and the first slider 103, and the toothed plate 105 is engaged with the damping gear 106 with a damper to provide movement resistance; the triangular flip plate 201 of the flip mechanism 2 is embedded with a double-sided smart display screen, and the display mode is switched by pressing and flipping: the first smart screen is connected to the camera 7 to display the student screen, and the second smart screen is connected to the camera 8 to record and project the teacher's performance movements; the bracket assembly 3 realizes the rapid storage and dust-proof covering of the support plate 302 through the pneumatic push rod 6 and the folding cloth 304, thereby realizing the multi-angle observation, dynamic capture and flexible management of teaching aids of music teaching as a whole.

[0059] The damping mechanism 1 enables the moving box 102 to slide smoothly in the circular frame 101 through the slide rail 104 and the first slider 103, and at the same time uses the engagement of the toothed plate 105 and the damping gear 106 to provide controllable resistance, ensuring that the display screen can stay stably at any position, making it easy to adjust the viewing angle.

[0060] Flipping mechanism 2 utilizes a triangular flip plate 201, integrated with a dual-sided intelligent display. The first intelligent screen, connected to camera 7, displays real-time classroom footage of students, facilitating teacher observation. The second intelligent screen, connected to camera 8 and a projector, captures and projects detailed movements of the teacher playing an instrument in real time, aiding instruction. During flipping, pressing flip plate 201 overcomes the resistance of blocking plate 204 and third spring 203, switching display modes and optimizing teaching flexibility.

[0061] Bracket assembly 3 incorporates pneumatic locking and folding dustproof designs: A pneumatic push rod 6, controlled by air pressure through annular duct 401 and conduit 402, releases support plate 302 when actuating lever 407, facilitating its removal. Once released, air pressure resets, locking push rod 6 firmly in place, ensuring stability. A folding sheet 304, linked to a shaping plate 303, can be quickly deployed to cover support plate 302 for dust protection or folded to provide space for textbook storage.

[0062] The device integrates mechanical damping, intelligent display, pneumatic locking and adjustable viewing angle design to optimize the interactivity, visualization and ease of operation of music teaching.

[0063] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, based on the innovative concept of the present invention, changes and modifications to the embodiments described herein, or equivalent structures, equivalent processes, or equivalent functional transformations made using the contents of the present invention's specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields, are all included in the scope of protection of the present invention's patent.
