Technical Field

[0001] The invention relates to the technical field of music teaching, in particular to a piano pedal movement amplitude indicating device for music teaching. Background Art

[0002] The piano is a keyboard instrument primarily composed of keys (both white and black) and a metal string soundboard. The typical 88-key piano has a pitch range from 27.5Hz to 4186.01Hz, while a 108-key piano reaches up to 7902.13Hz, encompassing virtually the entire musical range. This makes it one of the instruments with the widest range. It can be used for solo, duet, ensemble, and accompaniment, and is also an essential foundational instrument for music creation and aural training. Therefore, piano learning is often a crucial component of music education. The piano pedals are an integral part of the piano. Upright pianos typically have three pedals: the middle pedal, the left pedal, and the right pedal. The middle pedal, called the soft pedal, softens the sound and is often used during home practice to avoid disturbing others. The left pedal, called the soft pedal, alters the timbre, while the right pedal, called the sustain pedal, prolongs the note and enhances the acoustic effect.

[0003] In the current piano teaching process, music scores are usually placed on the piano stand, and the practitioner can play according to the music scores to achieve the effect of fingering practice. However, in the piano learning process, not only fingering practice is required, but also pedaling the piano according to the mood, rhythm and melody of the music. However, the current piano teaching often lacks accurate and effective prompts for the movement and movement amplitude of the piano pedals, resulting in the practitioner being unable to step on and switch the piano pedals in a timely and accurate manner, resulting in poor musical effect of the piano playing, which affects the piano teaching effect and is not conducive to rapid piano learning.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figure 1-Figure 5 As shown, a piano pedal movement amplitude indicator device for music teaching includes a placement plate 1 and an indicator structure 3 provided on the placement plate 1. A suction cup 2 is installed at the bottom of the placement plate 1.

[0041] The indication structure 3 includes an indication frame 31. The front of the indication frame 31 is provided with a soft pedal display screen 32, a muffler pedal display screen 33 and a damper pedal display screen 34 from left to right, and the indication frame 31 is also provided with a reminder for pedal switching. The soft pedal display screen 32 is provided with a first indicator for displaying the soft pedal action, the muffler pedal display screen 33 is provided with a second indicator for displaying the muffler pedal action, and the damper pedal display screen 34 is provided with a third indicator for displaying the damper pedal action. The outside of the soft pedal display screen 32, the muffler pedal display screen 33 and the damper pedal display screen 34 are all provided with status display lights 35.

[0042] Specifically, the first indicator includes an indicator area a and an indicator area b; the second indicator includes an indicator area c and an indicator area d; and the third indicator includes an indicator area e, an indicator area f, and an indicator area g.

[0043] Specifically, the reminder includes a soft pedal switch display light 37, a muffler pedal switch display light 38 and a sustain pedal switch display light 39 arranged in sequence from left to right. The soft pedal switch display light 37 is above the soft pedal display screen 32, the muffler pedal switch display light 38 is above the muffler pedal display screen 33, and the sustain pedal switch display light 39 is above the sustain pedal display screen 34.

[0044] Through the above, before use, the placement plate 1 is first placed on the piano stand by the suction cup 2 so that the indicator structure 3 is on the side of the music score, ensuring that the practitioner can see the indicator structure 3 synchronously when viewing the music score. Then, when the practitioner practices the piano according to the music score, if the sustain pedal needs to be stepped on, the sustain pedal switching indicator light 39 corresponding to the sustain pedal flashes to remind the practitioner to step on the sustain pedal. After the sustain pedal is stepped on, the status indicator light 35 outside the sustain pedal display screen 34 is lit, indicating that the sustain pedal is in the stepped state. At the same time, if the sustain pedal only needs to be stepped on, the sustain pedal switching indicator light 39 will flash to remind the practitioner to step on the sustain pedal. When the damper pedal is pressed one-quarter of the way down, the indicator area e on the damper pedal display screen 34 is lit. When the damper pedal is pressed one-half of the way down, the indicator area f on the damper pedal display screen 34 is lit. When the damper pedal is pressed fully, the indicator area g on the damper pedal display screen 34 is lit, thereby reminding the practitioner to step on the damper pedal, so that the practitioner can accurately grasp the stepping amplitude of the damper pedal. If the practitioner needs to switch to the soft pedal, the soft pedal switching indicator light 37 corresponding to the soft pedal flashes to remind the practitioner to step on the damper pedal in time. The soft pedal is pressed, and the pedal switching is completed. After the soft pedal is pressed, the status display light 35 outside the soft pedal display screen 32 is lit, and at the same time the status display light 35 outside the sustain pedal display screen 34 is extinguished. At the same time, when the indicator area a on the soft pedal display screen 32 is in a lit state, it means that the soft pedal is pressed, and when the indicator area b is in a lit state, it means that the soft pedal is lifted. Similarly, if it is necessary to switch to the muffler pedal, the muffler pedal switching display light 38 corresponding to the muffler pedal flashes, reminding the practitioner to step on the muffler pedal in time to complete the pedal switching. When the muffler pedal is switched, and the status display light 35 outside the muffler pedal display screen 33 is lit after the muffler pedal is stepped on, the status display light 35 outside the soft pedal display screen 32 is off. At the same time, when the indicator area d on the muffler pedal display screen 33 is in a lit state, it means that the muffler pedal is stepped on, and when the indicator area c is in a lit state, it means that the muffler pedal is lifted. In this way, accurate reminders of the piano pedal movements are achieved, which makes it convenient for practitioners to accurately control the movement amplitude of the piano pedals, thereby facilitating piano teaching demonstrations, improving piano teaching effects, and facilitating rapid piano learning.

[0045] Example 2

[0046] See also Figure 1-Figure 7 As shown, the placement plate 1 is also provided with an angle adjustment structure 4 for adjusting the angle of the indicating structure 3, and the angle adjustment structure 4 includes two support plates 41 symmetrically fixed on the top of the placement plate 1, and a rotating frame 42 arranged between the two support plates 41, and one side of one support plate 41 is provided with an adjusting member 43 for driving the rotating frame 42 to rotate, and shafts are installed on both sides of the rotating frame 42, and the two shafts are respectively rotatably connected to the adjacent support plates 41.

[0047] Specifically, the adjusting member 43 includes an adjusting rod 431 rotatably mounted on the side wall of the support plate 41, a main gear 432 is mounted on the adjusting rod 431, and a handwheel 434 is mounted at one end of the adjusting rod 431, one end of an axis rod passes through the support plate 41 and is mounted with a sub-gear 433 that meshes with the main gear 432.

[0048] When a piano practitioner is practicing the piano, the angle of the indicator structure 3 can be adjusted according to the practitioner's height and sitting posture. The specific adjustment steps are as follows:

[0049] The adjusting rod 431 is rotated by the hand wheel 434, so that the adjusting rod 431 drives the main gear 432 to rotate, and then the main gear 432 drives the sub-gear 433 engaged therewith to rotate synchronously, and then the sub-gear 433 drives the rotating frame 42 to rotate through the shaft, and then the rotating frame 42 drives the indicating structure 3 to rotate, so that the rotating frame 42 is tilted toward the practitioner (such as Figure 4 As shown) for practitioners to watch, the angle of the indicator structure 3 is adjusted, making it easier for practitioners of different heights to watch the indicator structure 3, greatly improving the applicability of the device, and thus facilitating piano practice for practitioners of different heights;

[0050] Secondly, it should be noted that the number of teeth of the sub-gear 433 is less than the number of teeth of the main gear 432, so that the gear ratio between the sub-gear 433 and the main gear 432 is greater than 1. The specific design can be made according to actual needs. For example: the number of teeth of the main gear 432 is set to 100, and the number of teeth of the sub-gear 433 is set to 20, then the gear ratio of the main gear 432 and the sub-gear 433 is 5, so as to achieve the purpose of deceleration, realize the slow rotation of the indicating structure 3, and facilitate the stable adjustment of the angle of the indicating structure 3.

[0051] At the same time, in this embodiment, Figure 1 、 Figure 3 、 Figure 4 as well as Figure 6-Figure 9 As shown, the angle adjustment structure 4 also includes a locking structure 7 for locking the adjustment member 43, and the locking structure 7 includes a support block 71 installed on the side wall of the support plate 41, a threaded rod 73 is screwed on the support block 71, and the top end of the threaded rod 73 is rotatably connected to a locking plate 72, and one side of the locking plate 72 is provided with a convex tooth that can engage with the main gear 432.

[0052] When adjusting the angle of the indicating structure 3, the threaded rod 73 is first rotated, and then the threaded rod 73 drives the locking plate 72 to descend, so that the convex teeth on the locking plate 72 are disengaged from the main gear 432, and then the angle of the indicating structure 3 is adjusted through the adjusting member 43. After the adjustment, the threaded rod 73 is rotated in the opposite direction, so that the threaded rod 73 drives the locking plate 72 to rise until the convex teeth on the locking plate 72 are engaged with the main gear 432, thereby locking and fixing the main gear 432, thereby preventing the main gear 432 from rotating accidentally, which causes the angle of the indicating structure 3 to change. This is beneficial for the indicating structure 3 to remain stable after adjustment, and further facilitates the viewing of piano practitioners.

[0053] Furthermore, if Figures 1-4 as well as Figure 6-Figure 9 As shown, the angle adjustment structure 4 also includes a shielding member for protecting the adjusting member 43, and the shielding member includes a shield 6 and two side plates 8 installed on the side walls of the support plate 41, and the two side plates 8 are symmetrically distributed on both sides of the main gear 432 and the sub-gear 433. Insert plates 9 are installed on both sides of the shield 6, and slots 10 for inserting the insert plates 9 are opened on the opposite sides of the two side plates 8.

[0054] When the device is in use, the shield 6 can be inserted between the two side plates 8 through the plug plate 9 and the slot 10, so that the shield 6 covers the main gear 432 and the sub-gear 433, thereby protecting the main gear 432 and the sub-gear 433 to ensure normal transmission between the main gear 432 and the sub-gear 433, facilitating the angle adjustment of the indicating structure 3, and when the main gear 432 and the sub-gear 433 need maintenance, the shield 6 can be pulled upward to move the shield 6 out from between the two side plates 8 to expose the main gear 432 and the sub-gear 433, facilitating maintenance or cleaning of the main gear 432 and the sub-gear 433, and further ensuring normal transmission between the main gear 432 and the sub-gear 433.

[0055] Example 3

[0056] See also Figure 1-Figure 7 As shown, a connecting component 5 is further provided between the indicator frame 31 and the rotating frame 42, and the connecting component 5 includes mounting bars 52 installed on both sides of the indicator frame 31, and a mounting groove 51 for plugging the two mounting bars 52 is opened on the inner wall of the rotating frame 42, and a pull groove 36 is also provided on the top of the indicator frame 31.

[0057] When the indicator structure 3 needs to be disassembled for maintenance, the indicator frame 31 can be pulled upward through the pull groove 36, so that the indicator frame 31 moves upward from the rotating frame 42, and drives the mounting bar 52 to move along the mounting groove 51 until the indicator frame 31 is separated from the rotating frame 42, so as to realize the disassembly of the indicator structure 3, and then the indicator structure 3 is maintained. After maintenance, the indicator frame 31 can be plugged into the rotating frame 42 through the mounting bar 52 and the mounting groove 51 to realize the plug-in fixation of the indicator structure 3 and complete the installation of the indicator structure 3, thereby realizing rapid disassembly and assembly of the indicator structure 3, facilitating the maintenance of the indicator structure 3, and ensuring the normal use of the indicator structure 3.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
