Description

Technical Field

[0001] This utility model relates to the field of music education technology, and in particular to a multifunctional teaching board for music education. Background Technology

[0002] In the field of music education, the staff notation board is an important device for conducting music theory teaching and keyboard performance demonstrations. It usually integrates functions such as piano keyboard, note marking area, and audio playback to help teachers convey core knowledge such as the correspondence between "staff notes and keyboard pitches" to learners.

[0003] Currently, most music education demonstration boards on the market adopt an integrated, monolithic structure, meaning all teaching components (such as the keyboard, writable staff, control panel, etc.) are integrated onto a single, solid board. While this structure can meet basic teaching needs, it has significant shortcomings in terms of storage and mobility: Firstly, the monolithic demonstration board has a fixed and typically large size, requiring a significant amount of space in classrooms or storage rooms when not in use. This can easily lead to storage conflicts with other teaching equipment, especially in situations with limited space. Secondly, when the demonstration board needs to be moved between different classrooms or used for outdoor or mobile music teaching, the weight and size of the monolithic structure make it difficult for a single person to move, requiring multiple people to work together. This not only reduces the efficiency of moving the teaching equipment but also increases the risk of damage to delicate components such as the keyboard and indicator lights due to the board's large size, thus increasing equipment maintenance costs.

[0004] In summary, the shortcomings of existing integrated teaching boards in terms of folding, storage, and portability make them unsuitable for the current needs of flexible and mobile music teaching scenarios. There is an urgent need for a teaching board structure that can optimize storage and mobility. Utility Model Content

[0005] In order to overcome the shortcomings of existing integrated teaching boards for music education, such as large storage space, inconvenience in moving and transporting, and easy damage to components during transportation, this utility model provides a multifunctional teaching board for music education.

[0006] The technical implementation scheme of this utility model is as follows: A multifunctional teaching board for music education includes a teaching board, hinges, locking blocks, return springs, buckles, teaching components, and positioning components. Two teaching boards are provided, symmetrically distributed, and the two teaching boards are connected by hinges installed symmetrically at the top and bottom to form a foldable structure. The hinges are fixed to the rear walls of the two teaching boards. A teaching component is provided between the front side walls of the two teaching boards. A matching groove is symmetrically opened on the right side of the rear side wall of the right teaching board. A locking block is slidably connected in the matching groove. Two return springs are connected between the locking block and the groove wall of the matching groove. A buckle is symmetrically fixed on the left side of the rear side wall of the left teaching board. The buckle has an arc-shaped barb on its outer side. The outer end face of the locking block has a guide slope. The arc-shaped barb of the buckle and the locking block form a locking engagement relationship. A positioning component is provided inside the two teaching boards.

[0007] Furthermore, the main frame of the demonstration board is made of aluminum alloy.

[0008] Furthermore, the guide slope surface of the card block is bonded with a polytetrafluoroethylene wear-resistant sheet.

[0009] Furthermore, the teaching components include a control panel, a note and note name marking area, indicator lights, a keyboard, a writable staff, and speakers. The note and note name marking area, keyboard, and writable staff are integrated and installed sequentially from top to bottom between the front sidewalls of the two teaching boards. The note and note name marking area, keyboard, and writable staff are all composed of two combined left and right parts, corresponding to the two teaching boards respectively. In the note and note name marking area, an indicator light is provided at the position of the staff corresponding to each pitch. Speakers are installed at the top corners of the front sidewalls of both teaching boards. The control panel is installed on the right side of the front sidewall of the right teaching board. The indicator lights, keyboard, and speakers are all electrically connected to the control panel, and the indicator lights are electrically connected to the keyboard via wires.

[0010] Furthermore, the writable musical staff is made of magnetic whiteboard material.

[0011] Furthermore, the positioning assembly includes a lifting rod, a rotating shaft, a toggle rod, a tenon rod, a groove rod, a tension spring, and a hanging ring. Both teaching boards have mounting slots inside, and these slots are interconnected. A groove rod is slidably connected to the mounting slot of the left teaching board, and a tenon rod is slidably connected to the mounting slot of the right teaching board. The groove rod and tenon rod are positioned opposite each other and form a snap-fit ​​relationship. A lifting rod is slidably connected inside both teaching boards, penetrating the inner cavity of the mounting slot. The top of the lifting rod extends out of the top wall of the teaching board and is rotatably mounted with a hanging ring. A rotating shaft is symmetrically rotatably connected to the mounting slots of both teaching boards. A toggle rod is fixed to each rotating shaft. A first sliding groove is provided on the outer end of the toggle rod, and a second sliding groove is provided on the inner end of each toggle rod. The outer end of the toggle rod is movably connected to the corresponding lifting rod via the first sliding groove, and the inner end of the toggle rod is movably connected to the corresponding tenon rod or groove rod via the second sliding groove. A tension spring connects the lower end of the lifting rod to the corresponding tenon rod or groove rod.

[0012] The present invention has the following advantages: 1. The device achieves back-to-back folding of the two teaching boards through a hinge. When folding, the buckle squeezes the block, and the return spring assists the block in locking the buckle, which can quickly fix the folded state, greatly reduce the overall volume, facilitate the movement and transportation between teaching scenarios and the storage when not in use, and solve the problem that traditional fixed teaching boards are not easy to carry.

[0013] 2. With the help of the positioning components, the gravity of the suspended teaching board causes the tenon and groove rods to slide downwards, and under the action of the actuating rod, they move closer to each other and lock into place, thus locking the teaching board in its unfolded state. This prevents angular displacement due to the rotatable nature of the hinges after unfolding, ensuring the stable operation of teaching components such as the keyboard and indicator lights, and not affecting the teaching demonstration process.

[0014] 3. The teaching components are electrically linked with the keyboard, indicator lights, and speakers. When playing, the indicator light at the corresponding position on the staff lights up and the speaker outputs audio. Combined with the writable staff, it can intuitively present the relationship between "staff notes - keyboard pitch - sound", helping learners to quickly understand music theory and reducing the difficulty of teaching.

Detailed Implementation

[0023] Example: A multifunctional teaching board for music education, such as... Figures 1-7 As shown, the device includes a teaching board 1, hinges 7, locking blocks 8, a return spring 9, a buckle 10, teaching components, and positioning components. Two teaching boards 1 are provided, symmetrically distributed left and right. The two teaching boards 1 are connected by hinges 7 installed symmetrically at the top and bottom, forming a foldable structure. The hinges 7 are fixed to the rear walls of the two teaching boards 1. With the help of the two hinges 7, the two teaching boards 1 can be folded by fitting back-to-back around the hinges 7. The main frame of the teaching board 1 is made of aluminum alloy, which reduces the overall weight and makes it easy to carry. A teaching component is located between the front side walls of the two teaching boards 1. The right side of the rear side wall of the right teaching board 1 has symmetrically opened mating grooves at the top and bottom. Locking blocks 8 are horizontally slidably connected within the mating grooves. The locking blocks 8 are connected to the groove walls of the mating grooves. Two return springs 9 are connected between them. A buckle 10 is symmetrically fixed to the left side of the rear wall of the left teaching board 1. The buckle 10 has an arc-shaped barb on its outer side, and the outer end face of the locking block 8 has a guide slope. When the two teaching boards 1 are folded back to back, the buckle 10 presses against the guide slope of the locking block 8 through its arc-shaped barb, causing the locking block 8 to automatically engage with the arc-shaped barb of the buckle 10, thus locking the teaching board 1 in its folded state. A polytetrafluoroethylene wear-resistant sheet is attached to the guide slope surface of the locking block 8, which reduces frictional wear between the arc-shaped barb of the buckle 10 and the slope of the locking block 8, preventing wear of the locking block 8 due to long-term folding and unfolding operations, and extending the service life of the folding locking mechanism. Positioning components are provided inside both teaching boards 1.

[0024] like Figures 1-2As shown, the teaching components include a control panel 101, a note and note name marking area 2, indicator lights 3, a keyboard 4, a writable staff 5, and a speaker 6. The note and note name marking area 2, the keyboard 4, and the writable staff 5 are integrated sequentially from top to bottom between the front walls of the two teaching boards 1. Each of these components is composed of two combined left and right parts, corresponding to the two teaching boards 1 respectively, and can fold with the teaching boards 1. The writable staff 5 is made of magnetic whiteboard material and can attract magnetic note cards, assisting teachers in flexibly demonstrating note position changes and enriching teaching methods. Indicators are provided on the staff position corresponding to each pitch in the note and note name marking area 2. The indicator lights 3 and the top corners of the front walls of both teaching boards 1 are embedded with speakers 6, which are used to play real-time sounds of the piano keyboard 4 being played, preset music demonstration audio, etc. The right side of the front wall of the right teaching board 1 is equipped with a control panel 101 by screws. The indicator lights 3, the piano keyboard 4 and the speakers 6 are all electrically connected to the control panel 101. The control panel 101 can integrate and control the functions of the piano keyboard 4, indicator lights 3 and speakers 6, including volume adjustment, teaching mode switching, demonstration audio playback / pause and other operations. The indicator lights 3 are electrically connected to the piano keyboard 4 by wires. When a specific note is played on the piano keyboard 4, the indicator lights 3 corresponding to the position on the staff will light up synchronously to intuitively show the position of the note on the staff.

[0025] like Figure 4 , Figure 6 and Figure 7 As shown, the positioning assembly includes a lifting rod 11, a rotating shaft 12, a toggle rod 13, a tenon rod 15, a groove rod 16, a tension spring 17, and a hanging ring 18. Both teaching boards 1 have mounting slots 19 inside, and these slots 19 are interconnected. A groove rod 16 is horizontally slidably connected within the mounting slot 19 of the left teaching board 1, and a tenon rod 15 is horizontally slidably connected within the mounting slot 19 of the right teaching board 1. The groove rod 16 has a groove, and the tenon rod 15 has a protruding tenon that matches the groove of the groove rod 16. The groove rod 16 and the tenon rod 15 are positioned opposite each other. A lifting rod 11 is vertically slidably connected within both teaching boards 1, and the lifting rod 11 penetrates the inner cavity of the mounting slot 19. The top of the teaching board 1 extends out of the top wall and is rotatably mounted with a hanging ring 18. The two teaching boards 1 are symmetrically connected to the mounting grooves 19, and the rotating shafts 12 are fixedly connected to the rotating shafts 12. The outer end (lower part) of the rotating shaft 13 is provided with a first sliding groove 14, and the inner end (higher part) of the two rotating shafts 13 is provided with a second sliding groove 141. The outer end of the rotating shaft 13 is movably connected to the corresponding lifting rod 11 through the first sliding groove 14, and the inner end of the rotating shaft 13 is movably connected to the corresponding tenon rod 15 or groove rod 16 through the second sliding groove 141. The lower end of the lifting rod 11 is connected to the corresponding tenon rod 15 or groove rod 16 with an obliquely arranged tension spring 17.

[0026] In the initial state, the two teaching boards 1 are unfolded. When in use, the device is suspended on the pre-set hooks on the wall by the hanging ring 18 at the top. After the hanging ring 18 is suspended, the teaching board 1 is released and slides downward under the action of gravity, which drives the tenon 15 and groove 16 inside to move downward, while the lifting rod 11 remains at this height. The movement of the tenon 15 and groove 16 will drive the actuating rod 13 to rotate around the axis of the rotating shaft 12 through the cooperation with the second sliding groove 141. The outer end of the actuating rod 13 moves upward and the inner end moves downward. When the actuating rod 13 rotates, the second sliding groove 141 forces the tenon 15 and groove 16 to slide closer to each other along the mounting groove 19. The tension spring 17 is stretched and deformed simultaneously. The protruding tenon of the tenon 15 will engage with the groove of the groove 16, thereby locking the unfolded state of the two teaching boards 1 and preventing the teaching boards 1 from shifting at an angle due to the hinge 7 in the unfolded state, thus ensuring the stability of the teaching process.

[0027] After the device is put into teaching use, the piano keyboard 4 demonstrates the notes, and the indicator lights 3 corresponding to the positions of the staff light up synchronously. The playing electrical signals of the piano keyboard 4 are received and processed by the control panel 101, and the corresponding audio is played by the speaker 6. During the teaching process, the control panel 101 can also select modes such as "single note demonstration" and "chord performance demonstration" to play the corresponding demonstration audio by the speaker 6, or adjust the volume of the speaker 6 to suit the teaching scenario. Combined with the music theory writing demonstration on the writable staff board 5, the teaching content such as music reading and playing skills is demonstrated.

[0028] When the teaching is finished and the device needs to be stored, first remove it from the wall so that the hanging ring 18 is disengaged from the wall hook. After the hanging ring 18 is no longer under force, the tension spring 17 rebounds and resets, causing the lifting rod 11 to slide downward. Under the reset action of the tension spring 17, the tenon rod 15 and the groove rod 16 will also move away from each other. This action simultaneously drives the actuating rod 13 to rotate in the opposite direction along the axis of the rotating shaft 12 and reset. After the tenon rod 15 and the groove rod 16 separate, the unfolded locking state of the teaching board 1 is released. At this time, the two teaching boards 1 can be folded back to back. During the folding process, the arc-shaped barb of the buckle 10 presses the guide slope of the locking block 8, causing the locking block 8 to slide outward and press down. When the circular barb of the latch 10 is fully pushed into the mating groove, the latch 8 moves inward under the reset action of the reset spring 9, thereby engaging the circular barb of the latch 10 and locking the teaching board 1 in the folded state, reducing the overall volume and making it easier to carry and store. When the teaching board 1 needs to be unfolded again, the latch 8 is pushed outward to compress the reset spring 9 until the latch 8 disengages from the circular barb of the latch 10. Then, the teaching board 1 is rotated outward to a horizontal position, and the latch 8 is released. The latch 8 rebounds and resets under the reset action of the reset spring 9, completing the unfolding preparation for use in teaching.
