Description

Technical Field

[0001] This utility model relates to the technical field of fingering practice devices, specifically a fingering auxiliary practice device for music teaching. Background Technology

[0002] In the field of music education, fingering aids are important tools to help learners master instrument fingering techniques. By simulating the keys or string positions of a real instrument, they allow learners to practice fingering without actually playing the instrument, effectively improving practice efficiency and learning outcomes.

[0003] Existing fingering aids for music teaching typically feature adjustable finger spacing to accommodate different learners' finger conditions and fingering habits. However, in practice, it has been found that adjusting the finger spacing alters the angle between the fingers and the pressure plate. During subsequent pressing exercises, this change in angle alters the point of force and direction of friction when the fingers press on the pressure plate, making the fingers prone to slippage. This slippage not only affects the accuracy of the learner's pressing movements, preventing precise simulation of actual instrument fingering, but may also lead to incorrect fingering habits, significantly reducing practice effectiveness and failing to meet the demands of high-quality music fingering instruction and training.

[0004] Therefore, existing fingering aids for music teaching need to be improved to solve the problem of finger slippage when pressing. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a fingering auxiliary practice device for music teaching.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A fingering aid for music teaching, including a handle;

[0008] The adjusting cylinder is rotatably mounted on the handle via a rotating shaft. Inside it is a spring and a slide rod that is elastically connected to the spring. One end of the slide rod extends out of the adjusting cylinder and is fixed with a U-shaped pressure plate.

[0009] The U-shaped pressure plate is hollow inside, and the two side wings are bent towards the central area of ​​the U-shaped pressure plate to form an extension and a placement area that can accommodate fingers. A central airbag is connected to the upper surface of the web of the U-shaped pressure plate, and side airbags are connected to both side wings. After the side airbags are inflated, they can extend towards the finger side of the placement area.

[0010] When a user presses their finger into the U-shaped pressure plate, the air in the central airbag is compressed and dispersed into the side airbags on both sides, causing them to expand and forming a structure that restricts the finger's posture.

[0011] Preferably, the air volume of the central airbag in its natural state is 1.5 to 2 times the air volume of the two side airbags in their inflated state.

[0012] Preferably, after the central airbag is squeezed and contracted by the finger, wrinkles are formed on its surface to increase friction with the finger.

[0013] Preferably, the bending angle of the extension is 30~50°.

[0014] Preferably, an auxiliary plate is fixed inside the handle, and an adjustment port is provided on the auxiliary plate. A threaded sleeve is provided at the end of the adjustment cylinder, and a threaded knob is threadedly connected to the threaded sleeve. The threaded knob slides through the adjustment port, and a washer is fitted on the threaded knob. When the threaded knob is turned until the washer abuts against the auxiliary plate, the relative position of the handle and the adjustment cylinder is locked.

[0015] Preferably, a flexible pad is provided on one side of the handle, and the flexible pad is made of silicone material to fit the user's palm.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: The designed U-shaped pressure plate structure can guide and constrain the movement trajectory of the user's fingers, effectively avoiding slippage caused by angle deviation during pressing. Simultaneously, the lateral airbags on both sides of the U-shaped pressure plate and the central airbag in the middle of the abdominal plate form a linkage constraint mechanism: the lateral airbags provide lateral support to the knuckles through adaptive inflation pressure, while the central airbag in the abdominal plate provides vertical buffer support for the fingertip pressing area. The two work together to dynamically restrict finger posture, preventing excessive twisting of the finger joints or force deviation, thus improving the standardization and training efficiency of finger technique practice from both movement trajectory and posture control.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Example

[0025] like Figures 1-4 As shown, a fingering aid for music teaching includes a handle 1; a flexible pad 4 is provided on one side of the handle 1. The flexible pad 4 is made of silicone material, which makes it easy to fit the user's palm and provide the user with a stable grip point.

[0026] The adjustment cylinder 2 is rotatably mounted on the handle 1 via a pivot. Inside, there is a spring 22 and a slide rod 21 elastically connected to the spring 22. One end of the slide rod 21 extends outside the adjustment cylinder 2 and is fixed with a U-shaped pressure plate 23. The internal spring 22 and slide rod 21 form an elastic telescopic structure. When the user presses the U-shaped pressure plate 23, the slide rod 21 compresses the spring 22 inside the adjustment cylinder 2, simulating the resistance feedback of a musical instrument key, helping the user feel the realistic pressure applied.

[0027] An auxiliary plate 3 is fixed inside the handle 1. An adjustment port 31 is provided on the auxiliary plate 3. A screw sleeve 32 is provided at the end of the adjustment cylinder 2. A threaded knob 33 is threadedly connected to the screw sleeve 32. The threaded knob 33 slides through the adjustment port 31, and a washer 34 is fitted on the threaded knob 33. When the threaded knob 33 is turned until the washer 34 abuts against the auxiliary plate 3, the relative position of the handle 1 and the adjustment cylinder 2 is locked. In addition, by pulling the threaded knob 33, the relative angle between the adjustment cylinder 2 and the handle 1 can be changed, thereby adjusting the tilt direction of the U-shaped pressure plate 23 to adapt to the pressing angle requirements of different musical instrument fingerings.

[0028] The U-shaped pressure plate 23 is hollow inside, and the two side wings bend towards the central area of ​​the U-shaped pressure plate 23 to form an extension 231 (bending angle of 30~50 degrees), forming a placement area that can accommodate fingers, thus initially defining the lateral position of the fingers in space and reducing lateral slippage. A central airbag 24 is connected to the upper surface of the web of the U-shaped pressure plate 23, and side airbags 25 are connected to both side wings. After the side airbags 25 are inflated, they can extend towards the finger side of the placement area. When the user's fingers are pressed into the U-shaped pressure plate 23, the air in the central airbag 24 is compressed and dispersed into the side airbags 25, causing them to inflate and forming a structure that restricts the finger posture.

[0029] In addition, both the central airbag 24 and the side airbags 25 have anti-slip stripes on their surfaces to increase friction with the fingers. The air capacity of the central airbag 24 in its natural state is 1.5 to 2 times that of the two side airbags 25 when inflated. This allows the air in the central airbag 24 to quickly disperse to the side airbags 25 when the user presses down, causing them to expand synchronously. The side airbags 25 extend towards the sides of the fingers, gripping the knuckles from the side; the central airbag 24 provides support from the fingertips. Together, they form a three-dimensional wrap around the fingers, restricting twisting, tilting, or other undesirable postures during pressing.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
