Description

Technical Field

[0001] This invention relates to the field of musical instrument playing aids, and in particular to a music stand for piano playing that facilitates page turning. Background Technology

[0002] With the continuous progress of education, people are paying more and more attention to music learning, and more and more people are starting to study music. In various music teaching and learning processes, the music stand has always been an indispensable tool, especially in vocal music instruction.

[0003] Currently, a Chinese patent discloses a music stand for vocal music teaching (publication number CN218898750U). By placing the required sheet music in several music holders in sequence, when the performer needs to turn the sheet music during performance teaching, a foot pedal activates a sensor to control a drive motor. The drive motor rotates an L-shaped support rod, which in turn rotates the outer cylinder synchronously. This connects the page-turning lever to the L-shaped frame on each music holder, enabling automatic page turning. This allows the performer's hands to be fully engaged in playing without being distracted by turning pages, making it convenient for the performer to use.

[0004] Since the sheet music folders are stacked together, the number of sheet music pages that a performer needs to prepare varies each time, which results in different stacking heights. The drive motor in the device is controlled by a foot-operated sensor to turn the pages, requiring the staff to adjust the motor's trajectory in real time according to the number of sheet music pages. Otherwise, the motor may turn multiple pages at once or fail to turn pages effectively, which could easily lead to performance accidents. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems by providing a music stand for piano playing that facilitates page turning, thereby improving the problem that existing music stand page turning devices cannot effectively turn pages according to the number of pages in the music score, which can easily lead to performance accidents.

[0006] A music stand for easy page turning in piano playing includes: a shelf and a foot pedal controller, the foot pedal controller being disposed below the shelf; an adjustment device mounted on the surface of the shelf; wherein the adjustment device includes a music clip and a servo motor, the music clip being placed inside the shelf, one end of the music clip having a guide groove, the servo motor being fixedly connected to the surface of the shelf, the output shaft of the servo motor being fixedly connected to an adjustment mechanism in contact with the guide groove, and a trigger mechanism in contact with the guide groove being installed inside the adjustment mechanism.

[0007] Preferably, the triggering mechanism includes a connecting ring slidably connected to the inner wall of the adjusting mechanism. An adjusting block is fixedly connected to the inner wall of the connecting ring. One end of the adjusting block passes through the adjusting mechanism and contacts the guide groove. The other end of the adjusting block contacts a pressure sensor embedded in the inner wall of the adjusting mechanism. By setting the triggering mechanism, when the adjusting mechanism just passes through the guide groove, the adjusting block is squeezed by the guide groove and moves. The adjusting block squeezes the pressure sensor. At this time, the pressure sensor detects the pressure signal and feeds it back to the foot pedal controller. The foot pedal controller controls the servo motor to stop running according to the preset program. At this time, the adjusting mechanism only stays in the guide groove of the top sheet music clip. During the subsequent page turning process controlled by the user, the adjusting mechanism can only drive the top sheet music clip to turn the page through the guide groove. There is no need to worry about the servo motor and the adjusting mechanism working together to turn multiple pages at once or not turning any pages at all, reducing the probability of performance accidents.

[0008] Preferably, one end of the adjusting block has an arc-shaped cross-section, and all the corners of the adjusting block are rounded. This reduces the resistance between the adjusting block and the guide groove, ensuring that the adjusting block can be smoothly pushed back into the adjusting mechanism by the guide groove.

[0009] Preferably, a first spring is sleeved on the surface of the adjusting block, and the two ends of the first spring are in contact with the adjusting mechanism and the connecting ring, respectively. The first spring is always in a compressed state, which can ensure that after the adjusting block is completely separated from the guide groove, the first spring can separate the adjusting block from the pressure sensor and reset it, without the need for the user to manually reset it, further reducing the user's burden.

[0010] Preferably, the other end of the adjusting block has a mounting cavity, and a pressure block that contacts the pressure sensor is slidably connected to the inner wall of the mounting cavity. A second spring is provided on the inner wall of the mounting cavity, and the two ends of the second spring are in contact with the mounting cavity and the pressure block, respectively. The second spring is in a compressed state at this time. Through the cooperation of the pressure block and the second spring, the pressure applied by the adjusting block to the pressure sensor can be limited to a reasonable range, avoiding excessive pressure on the pressure sensor and reducing the probability of damage to the pressure sensor.

[0011] Preferably, a protective groove is provided at the other end of the pressure block, and one end of the second spring passes through the interior of the protective groove and contacts the inner wall of the protective groove. This can reserve enough space for the second spring, which can not only limit the running trajectory of the second spring, but also prevent the second spring from being over-compressed and reduce the probability of damage to the second spring.

[0012] The beneficial effects of this invention are:

[0013] 1. By setting a trigger mechanism, when the adjustment mechanism just passes through the guide groove, the adjustment block is squeezed by the guide groove and moves. The adjustment block squeezes the pressure sensor. At this time, the pressure sensor detects the pressure signal and feeds it back to the foot pedal controller. The foot pedal controller controls the servo motor to stop running according to the preset program. At this time, the adjustment mechanism only stays in the guide groove of the top sheet music clip. In the subsequent process of the user controlling the page turning, the adjustment mechanism can only drive the top sheet music clip to turn the page through the guide groove. There is no need to worry about the servo motor and the adjustment mechanism working together to turn multiple pages at once or not turn any pages at all, which reduces the probability of performance accidents.

[0014] 2. By using the pressure block and the second spring in combination, the pressure applied by the adjusting block to the pressure sensor can be limited to a reasonable range, avoiding excessive pressure on the pressure sensor and reducing the probability of damage to the pressure sensor.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] In practical implementation: such as Figure 1-4 As shown, a music stand for piano playing with easy page turning includes: a shelf 1 and a foot pedal controller 2, the foot pedal controller 2 being disposed below the shelf 1; an adjustment device 3, the adjustment device 3 being mounted on the surface of the shelf 1; wherein, the adjustment device 3 includes a music clip 31 and a servo motor 32, the music clip 31 being placed inside the shelf 1, one end of the music clip 31 having a guide groove 311, the servo motor 32 being fixedly connected to the surface of the shelf 1, the output shaft of the servo motor 32 being fixedly connected to an adjustment mechanism 33 that contacts the guide groove 311, the adjustment mechanism 33 having a trigger mechanism 34 that contacts the guide groove 311 installed inside the adjustment mechanism 33 {the adjustment mechanism 33 includes a trigger mechanism 34 that contacts the guide groove 311}. The L-shaped mounting rod of the output shaft of the servo motor 32 has a connecting tube fixedly connected to the other end. A trigger rod is slidably connected to the inner wall of the connecting tube. Both ends of the trigger rod extend to the outside of the connecting tube. A return spring fixedly connected to the connecting tube is fixedly connected to the surface of the trigger rod. A groove set inside the guide groove 311 is sleeved on the surface of the trigger rod. The pressure sensor 343 is fixedly connected to the deepest part of the groove. The connecting ring 341 is slidably connected to the inner wall of the groove. One end of the adjusting block 342 extends to the outside of the groove. One end of the trigger rod has an inclined surface. The above-mentioned adjusting mechanism 33 is the structure disclosed in the comparative case. The specific operating principle and beneficial effects have not changed, and will not be described in detail here.

[0022] like Figure 4As shown, the triggering mechanism 34 includes a connecting ring 341 slidably connected to the inner wall of the adjusting mechanism 33. An adjusting block 342 is fixedly connected to the inner wall of the connecting ring 341. One end of the adjusting block 342 passes through the adjusting mechanism 33 and contacts the guide groove 311. The other end of the adjusting block 342 contacts a pressure sensor 343 embedded in the inner wall of the adjusting mechanism 33. One end of the adjusting block 342 has an arc-shaped cross-section, and all corners of the adjusting block 342 are rounded. A first spring 344 is sleeved on the surface of the adjusting block 342. The two ends of the first spring 344 are respectively connected to the adjusting mechanism 33 and the connecting ring 341. 41. The first spring 344 is always in a compressed state. The other end of the adjusting block 342 is provided with a mounting cavity 345. The inner wall of the mounting cavity 345 is slidably connected to a pressure block 346 that contacts the pressure sensor 343. The inner wall of the mounting cavity 345 is provided with a second spring 347. The two ends of the second spring 347 are in contact with the mounting cavity 345 and the pressure block 346 respectively. The second spring 347 is in a compressed state at this time. The other end of the pressure block 346 is provided with a protective groove 348. One end of the second spring 347 passes through the interior of the protective groove 348 and contacts the inner wall of the protective groove 348.

[0023] In use, when the servo motor 32 drives the adjustment mechanism 33 to move into the guide groove 311, the adjustment mechanism 33 loses resistance and extends into the guide groove 311. The adjustment mechanism 33 moves the entire adjustment mechanism 33 into the guide groove 311. During this process, the arc surface of the adjustment block 342 contacts the inner wall of the guide groove 311. In subsequent movements, the guide groove 311 pushes the adjustment block 342 back into the adjustment mechanism 33. The adjustment block 342, through the mounting cavity 345, drives the pressure block 346 to contact and press against the pressure sensor 343. At this time, the pressure sensor... After detecting the pressure signal, 343 transmits the signal to the foot pedal controller 2. The foot pedal controller 2 stops the servo motor 32 from rotating according to the preset instructions of the staff. At this time, the adjustment mechanism 33 is exactly in the guide groove 311 of the uppermost sheet music clip 31. When the user controls the servo motor 32 to drive the adjustment mechanism 33 to rotate through the foot pedal controller 2, the adjustment mechanism 33 can only drive the uppermost sheet music clip 31 to turn the pages through the guide groove 311. There is no need to worry about the servo motor 32 and the adjustment mechanism 33 turning multiple pages at once or not turning any pages at all, which reduces the probability of performance accidents.

[0024] It should be noted that the preset instruction is that after the pressure sensor 343 transmits the pressure signal to the foot pedal controller 2, the foot pedal controller 2 controls the servo motor 32 to stop based on the feedback signal. The specific compilation of this instruction needs to be tailored according to the software used by the user and the models of the foot pedal controller 2, servo motor 32, and pressure sensor 343, which will not be elaborated here. The foot pedal controller 2, servo motor 32, and pressure sensor 343 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the foot pedal controller 2, servo motor 32, and pressure sensor 343 can be powered by the built-in power supply or by AC power. The specific power supply method is selected according to the situation, which will not be elaborated here.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
