Abstract
Description
Technical Field
[0001] This invention relates to the field of stringed instrument technology, and more particularly to an electronic musical instrument for simulating chord practice and its control method. Background Technology
[0002] Playing music on electronic instruments requires playing sheet music, which contains various chords. Chords are an important part of music. Practicing chords mainly involves a group of sounds with certain interval relationships, that is, combining three or more notes vertically according to the stacking relationship of thirds or non-thirds, so as to achieve the purpose of playing music and improve the performer's proficiency. This article provides technical insights into chord practice.
[0003] The study of chord exercises revealed the following problems:
[0004] When players practice chords on an electric guitar, they do so by repeatedly sliding the strings. However, chords involve many combinations, and prolonged sliding can cause finger fatigue and even be counterproductive. Chords composed of multiple notes are difficult for beginners to play, increasing the difficulty of chord practice. Furthermore, the complexity of switching between various chords makes playing music difficult and prevents the player from improving their proficiency.
[0005] This invention primarily addresses the problems that prolonged sliding of chords composed of multiple notes can cause finger fatigue in beginners, leading to less effective practice, and the complexity of switching between various chords, which hinders the improvement of the performer's proficiency. Summary of the Invention
[0006] To address the aforementioned technical problems, this invention provides an electronic musical instrument for simulating chord practice and its control method, thereby resolving the issues described in the background section.
[0007] The purpose and effectiveness of this invention, which provides an electronic musical instrument for simulating chord practice and its control method, are achieved by the following specific technical means: An electronic musical instrument for simulating chord practice includes a servo motor, a transmission column installed at the output end of the servo motor, an output module installed directly below the transmission column, and a communication surround assembly provided on the outer side of the transmission column. The surround assembly includes a transmission plate, a transmission shaft, a housing, a connecting shaft, and a limiting spring. The transmission shaft is installed at the bottom of the transmission plate, and the connecting shaft is connected to the outer side of the transmission plate. A limiting spring is installed at the top of the connecting shaft, and the housing is connected to the end of the limiting spring away from the connecting shaft.
[0008] Furthermore, the surface of the transmission column is threaded.
[0009] Furthermore, the transmission plate is arc-shaped, with the inner side curvature matching the outer side curvature of the transmission column. The transmission plate is also convex, and there are six transmission plates. Each of the six transmission plates has a transmission shaft installed at its bottom. The transmission shaft is connected to the output module for signal transmission. The six transmission plates are arranged around the outer side of the transmission column, and each of the six transmission plates has a thread that matches the transmission column on the side adjacent to it. A translation component for driving is installed on the outer side of the transmission plate.
[0010] Furthermore, the sleeve is arranged in a scoop shape, and its sleeve is nested on the outer side of the connecting shaft. The opening on the side of the sleeve adjacent to the transmission plate matches the protruding end of the transmission plate.
[0011] Furthermore, in its initial state, the connecting shaft is completely embedded inside the housing, and the length of the connecting shaft is the same as the length of the transmission plate.
[0012] Furthermore, the translation assembly includes a main drive rod, a secondary drive rod, a drive spring, and a pressing shaft. The drive spring is installed at the bottom of the main drive rod, the secondary drive rod is provided on one side of the main drive rod, and the pressing shaft is installed at one end of the secondary drive rod.
[0013] Furthermore, an inclined groove is provided on one side of the drive main rod, and a gap is left between the drive main rod and the pressing shaft. There are four drive main rods, which correspond to the four commonly used chords. A drive auxiliary rod is provided on one side of each of the four drive main rods.
[0014] Furthermore, each of the four drive auxiliary rods has a matching inclined groove on the side adjacent to the drive main rod. The drive auxiliary rod is perpendicularly engaged with the drive main rod through the groove, and a pressing shaft is provided at one end of each of the four drive auxiliary rods.
[0015] Furthermore, the pressing shafts are arranged in an arc shape, and each of the four pressing shafts is connected to three sleeves at the end away from the drive auxiliary rod, which respectively correspond to the four commonly used chords. The four pressing shafts are arranged at equal intervals from top to bottom.
[0016] Furthermore, the specific operation steps of the control method for simulating chord exercises are as follows:
[0017] S1: Press the drive rod to move it downwards and squeeze the drive spring. During the downward movement of the drive rod, the drive auxiliary rod is driven to move horizontally through the inclined groove on one side.
[0018] S2: The drive rod pushes the pressing shaft and drives the three sleeves to move towards the outer side of the transmission column. At the same time, the three sleeves push the three transmission plates to fit against the outer side of the transmission column.
[0019] S3: At the same time, the servo motor drives the transmission column to rotate, so that the transmission column moves downward through the thread on one side of the transmission plate during the rotation process.
[0020] S4: The transmission plate drives the connecting shaft to move downward through the protruding end. The downward movement of the connecting shaft pulls the limit spring, and at the same time, the limit spring limits the connecting shaft.
[0021] S5: When the transmission plate moves downward, it drives the transmission shaft to move downward, so that the transmission shaft is connected to the output module, thereby producing chordal sounds.
[0022] Beneficial effects:
[0023] 1. When you need to practice one of the four chords, press down on one of the corresponding drive rods. The drive rod moves downward under pressure and squeezes the drive spring, so that the drive rod drives the drive auxiliary rod to move towards the transmission column through the inclined groove side. This drives the drive auxiliary rod to push the pressing shaft to move towards the transmission column side. At this time, the three sleeves connected to the pressing shaft are pushed by the thrust to make the transmission plate fit against the outer side of the transmission column.
[0024] 2. When the transmission plate and the transmission column are in contact, the servo motor drives the transmission column to rotate, causing the transmission plate to move downward. During the downward movement of the transmission plate, the connecting shaft moves through the protruding end. The connecting shaft moves downward and pulls the limit spring. At this time, the transmission plate pushes the output shaft downward to connect with the output module. It connects with the output module through six different transmission shafts, thereby producing different sounds, thus reducing the difficulty of chord practice and making it easier for the performer to improve their proficiency.
[0025] 3. Release the pressure on the drive main rod. The drive spring pushes the drive main rod upward through its own elasticity. The drive auxiliary rod drives the pressing shaft to cancel the thrust on the transmission plate and causes the transmission plate to separate from the outer side of the transmission column. The transmission plate is pulled upward by the limit spring at the top of the connecting shaft and resets. This causes the transmission plate to pull the transmission shaft to disconnect from the output module, thereby stopping the sound. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0037] As attached Figure 1 To be continued Figure 8 As shown:
[0038] Example 1:
[0039] This embodiment provides an electronic musical instrument for simulating chord practice, including a servo motor 1, a transmission column 2 installed at the output end of the servo motor 1, an output module 5 installed directly below the transmission column 2, and a communication-enabled surround assembly provided on the outer side of the transmission column 2. The surround assembly includes a transmission plate 4, a transmission shaft 401, a housing 402, a connecting shaft 403, and a limiting spring 404.
[0040] A transmission shaft 401 is installed at the bottom of the transmission plate 4, a connecting shaft 403 is connected to the outer side of the transmission plate 4, a limit spring 404 is installed at the top of the connecting shaft 403, and a sleeve 402 is connected to the end of the limit spring 404 away from the connecting shaft 403.
[0041] The surface of the transmission column 2 is threaded;
[0042] Among them, the transmission plate 4 is arc-shaped, and the arc of its inner side is consistent with the arc of the outer side of the transmission column 2. The transmission plate 4 is convex, and there are six transmission plates 4. The bottom of each of the six transmission plates 4 is equipped with a transmission shaft 401. After the transmission shaft 401 is connected to the output module 5, it can transmit signals. The six transmission plates 4 are arranged around the outer side of the transmission column 2, and the side of each of the six transmission plates 4 adjacent to the transmission column 2 is provided with a thread that matches the transmission column 2. The outer side of the transmission plate 4 is equipped with a translation component for driving.
[0043] The housing 402 is arranged in a scoop shape and is nested on the outer side of the connecting shaft 403. The opening on the side of the housing 402 adjacent to the transmission plate 4 matches the protruding end of the transmission plate 4.
[0044] The connecting shaft 403 is initially fully embedded inside the housing 402, and the length of the connecting shaft 403 is the same as the length of the transmission plate 4.
[0045] When the transmission plate 4 and the transmission column 2 are in contact, the servo motor 1 drives the transmission column 2 to rotate. The transmission column 2 matches the thread on one side of the transmission plate 4 through its surface thread, so that the transmission column 2 drives the transmission plate 4 to move downward during rotation. During the downward movement of the transmission plate 4, the connecting shaft 403 is moved through the protruding end. The connecting shaft 403 moves downward and pulls the limit spring 404. At this time, the transmission plate 4 pushes the output shaft 401 to move downward to connect with the output module 5. Through six different transmission shafts 401 connected to the output module 5, different sounds are produced.
[0046] Example 2:
[0047] The difference between this embodiment and embodiment 1 is that the translation component includes a main drive rod 3, a secondary drive rod 301, a drive spring 302, and a pressing shaft 303. The drive spring 302 is installed at the bottom of the main drive rod 3, the secondary drive rod 301 is provided on one side of the main drive rod 3, and the pressing shaft 303 is installed at one end of the secondary drive rod 301.
[0048] Among them, the drive main rod 3 has an inclined groove on one side, and there is a gap between the drive main rod 3 and the pressing shaft 303. There are four drive main rods 3, which correspond to the four sets of chords commonly used in the foundation. Each of the four drive main rods 3 has a drive auxiliary rod 301 on one side.
[0049] The four drive rods 301 are provided with a matching inclined groove on the side adjacent to the drive rod 3. The drive rods 301 are perpendicularly engaged with the drive rod 3 through the groove. One end of each of the four drive rods 301 is provided with a pressing shaft 303.
[0050] The pressing shaft 303 is arc-shaped. Each of the four pressing shafts 303 is connected to three housings 402 at the end away from the drive rod 301, and each corresponds to one of the four commonly used chords. The four pressing shafts 303 are arranged at equal intervals from top to bottom.
[0051] When practicing one of the four chord groups, press down on one of the corresponding drive rods 3. The drive rod 3 moves downward under pressure and squeezes the drive spring 302, causing the drive rod 3 to drive the drive auxiliary rod 301 towards the transmission column 2 via the inclined groove side. This, in turn, pushes the pressure shaft 303 towards the transmission column 2. At this time, the three sleeves 402 connected to the pressure shaft 303 are pushed by the thrust to make the transmission plate 4 fit against the outer side of the transmission column 2. During practice, by continuously pressing down on the drive rod 3, the drive auxiliary rod 301 continuously pushes the pressure shaft 303, keeping the transmission plate 4 in contact with the transmission column 2. In the closed state, when the practice is canceled, the pressure on the drive main rod 3 is released. The drive spring 302 pushes the drive main rod 3 upward through its own elasticity. The upward movement of the drive main rod 3 drives the drive auxiliary rod 301 to move away from the transmission column 2. At this time, the drive auxiliary rod 301 drives the pressure shaft 303 to cancel the thrust on the transmission plate 4 and causes the transmission plate 4 to separate from the outer side of the transmission column 2. After the pressure on the threaded side of the transmission column 2 is canceled, the transmission plate 4 is pulled upward by the limiting spring 404 at the top of the connecting shaft 403 and reset. This causes the transmission plate 4 to pull the transmission shaft 401 to disconnect from the output module 5, thereby stopping the vocal music.
[0052] Example 3:
[0053] This embodiment also provides a control method for simulating chord practice, the specific operation steps of which are as follows:
[0054] S1: Press the drive rod 3 to move it downwards and squeeze the drive spring 302. During the downward movement of the drive rod 3, the drive auxiliary rod 301 is driven to move horizontally through the inclined groove on one side.
[0055] S2: Drive rod 301 pushes pressing shaft 303 and drives three sleeves 402 to move towards the outer side of transmission column 2. The three sleeves 402 simultaneously push three transmission plates 4 to fit against the outer side of transmission column 2.
[0056] S3: At the same time, the servo motor 1 drives the transmission column 2 to rotate, so that the transmission column 2 moves downward through the thread on one side of the transmission plate 4 during the rotation.
[0057] S4: The transmission plate 4 drives the connecting shaft 403 to move downward through the protruding end. The downward movement of the connecting shaft 403 pulls the limiting spring 404, and at the same time, the limiting spring 404 limits the connecting shaft 403.
[0058] S5: When the transmission plate 4 moves downward, it drives the transmission shaft 401 to move downward, so that the transmission shaft 401 is connected to the output module 5, thereby producing chordal music.
[0059] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
