Description

Technical Field

[0001] This invention relates to the field of violin technology, specifically to a muscle memory-based standardized training device for basic violin skills. Background Technology

[0002] The chin rest is an accessory made of wood or other malleable material that is attached to the upper left side of the violin. When playing, the violinist rests the tailpiece on their collarbone, using their left chin to contact the chin rest, and works with their left hand to stabilize the violin. Currently, the chin rest is fixed in position with very little adjustment. This often causes discomfort for the player, and over time can lead to problems in the cervical spine, jaw, and shoulder and back muscles. Especially among beginners and self-learners, chin rest discomfort is one of the main problems causing incorrect violin holding, thus delaying their studies, or even leading to various jaw, neck, and shoulder problems, forcing many to give up violin learning altogether.

[0003] Therefore, there is an urgent need for a self-training device for violin fundamentals that can flexibly adjust the relationship between the chin rest and the neck, shoulders, and jaw to help learners find and adapt to the best way of holding the violin and posture to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a muscle memory type standardized training device for basic violin skills, so as to solve many problems caused by the inability of the existing chin rest installation position to be well adjusted in relation to the neck, shoulders and jaw, resulting in the left hand holding the violin and the right hand being unable to freely wield the bow and control the bow string contact point.

[0005] To achieve the above objectives, the present invention provides a muscle memory-based standardized training device for basic violin skills, comprising:

[0006] The body of the instrument has a first end and a second end that are positioned opposite to each other;

[0007] A 3D chin rest that is mounted on the first end of the instrument body and whose position can be adjusted significantly and precisely.

[0008] The bowing component is located between the first end and the second end. The top surface of the bowing component has a bowing groove that runs along the length of the bowing component. The bowing component is installed on the instrument body by a fastener sleeve-type right hand module that passes vertically through the bowing component and the instrument body. Before fastening the connection, the bowing component is rotated and adjusted so that the setting direction of the bowing component is consistent with the bowing direction.

[0009] A further improvement of the muscle memory type violin basic skills standardization training device of the present invention is that a first limiting member and a second limiting member are provided on the violin body corresponding to the bowing component;

[0010] By tightening the fastener, the restriction on the bow-carrying component is released, allowing the bow-carrying component to rotate around the fastener;

[0011] When the bow is moved within the bow groove, rotating the bow causes the bow-moving component to rotate clockwise and counterclockwise around the fastener, and abuts against the first and second limiting members, thereby limiting the rotation range of the bow-moving component.

[0012] This invention also provides a muscle memory-based standardized training device for basic violin skills, comprising:

[0013] The body of the instrument has a first end and a second end that are positioned opposite to each other;

[0014] A 3D chin rest that is mounted on the first end of the instrument body and is position-adjustable;

[0015] A mounting base that is detachably mounted on the body of the instrument and located between the first end and the second end;

[0016] A guide rod is mounted on the mounting base, and the direction of the guide rod is consistent with the direction of bow movement; and

[0017] A sleeve-type right-hand shape module is fitted onto the guide rod, and the sleeve-type right-hand shape module can move back and forth on the guide rod to simulate the bowing trajectory.

[0018] A further improvement of the muscle memory type violin basic skills standardization training device of the present invention is that it also includes an index finger buckle and a little finger buckle that are movably and adjustablely installed on the top of the sleeve-type right hand shape module, a horsehair clip installed on the bottom of the sleeve-type right hand shape module and located between the index finger buckle and the little finger buckle, and a thumb buckle that is fixed to the bottom of the sleeve-type right hand shape module and the horsehair clip.

[0019] The top surface of the index finger buckle has a first groove;

[0020] The top surface of the little finger buckle has a second groove;

[0021] The thumb buckle has a positioning hole that passes through the middle of the thumb buckle.

[0022] A further improvement of the muscle memory type violin basic skills standardization training device of the present invention is that the top surface of the first end is provided with a receiving groove, and the training device further includes a connecting column that is vertically movable and adjustablely installed on the first end and located in the receiving groove, the top end of the connecting column extending out of the top surface of the first end to form a support part.

[0023] The 3D chin rest slides onto the support portion.

[0024] A further improvement of the muscle memory type violin basic skills standardization training device of the present invention is that the bottom surface of the 3D chin rest is provided with a groove, and an opening is formed on the side of the 3D chin rest on the groove, and the setting direction of the groove is consistent with the length direction of the 3D chin rest.

[0025] The training device also includes an adjusting rod rotatably mounted on the wall of the chute and a slider slidably disposed in the chute and threadedly connected to the adjusting rod. The adjusting rod is oriented in the same direction as the length of the chute. The bottom surface of the slider is mounted on the support. By rotating the adjusting rod, the adjusting rod can move relative to the slider to achieve precise adjustment of the 3D chin rest.

[0026] A further improvement of the muscle memory type violin basic skills standardization training device of the present invention is that the violin body includes a first plate, a second plate, and a telescopic rod that is installed and connected between the first plate and the second plate and is telescopically adjustable.

[0027] The 3D chin rest is adjustablely mounted on the first plate.

[0028] A further improvement of the muscle memory type violin basic skills standardization training device of the present invention is that it also includes a fixing rod installed on the second end and whose setting direction is consistent with the setting direction of the violin body, a left hand shape module sleeved on the fixing rod, a palm support installed on one side of the adjustment seat, and a thumb baffle erected on the left hand shape module and located on the other side of the left hand shape module.

[0029] The top surface of the left-hand module has a number of recessed holes spaced apart along the length of the left-hand module.

[0030] A further improvement of the muscle memory type violin basic skills standardization training device of the present invention is that it also includes a dot laser locator installed on the second end and capable of emitting laser light. The setting direction of the dot laser locator is consistent with the setting direction of the violin body, and the emitting head of the dot laser locator is set facing outward from the violin body.

[0031] A further improvement of the muscle memory type violin basic skills standardization training device of the present invention is that it also includes a shoulder pad;

[0032] The bottom surface of the first end of the instrument body and the top surface of the shoulder pad are provided with a slot that runs horizontally through the instrument body. The shoulder pad is secured to the bottom end of the first end through the slot.

[0033] This invention features an adjustable 3D chin rest on the instrument body. By adjusting the 3D chin rest according to the user's needs, the user can ensure that the relationship between the neck, shoulders, jaw, and left hand is properly adjusted, thus avoiding the phenomenon of forcefully squeezing the instrument and causing lesions in the cervical spine, jaw, shoulder and back muscles.

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0049] The muscle memory type standardized training device for violin basic skills of the present invention will be described below with reference to the accompanying drawings.

[0050] See Figure 1In a first specific embodiment, a muscle memory type violin basic skills standardization training device includes: a violin body 10 having a first end and a second end set opposite to each other; a 3D chin rest 20 mounted on the first end of the violin body 10 and whose position is adjustable; a bowing member 30 located between the first end and the second end, the top surface of the bowing member 30 having a bowing groove 31 extending along the length direction of the bowing member 30, the bowing member 30 being mounted on the violin body 10 by fasteners 35 passing vertically through the bowing member 30 and the violin body 10, and before fastening the connection, the bowing member 30 is adjusted by rotation so that the setting direction of the bowing member 30 is consistent with the bowing direction.

[0051] The practitioner can flexibly rotate and adjust the bowing component 30 according to the desired bowing direction, place the bow in the bowing groove 31, and pull the bow to move the bow within the bowing groove 31 to practice bowing.

[0052] See Figure 1 and Figure 3 Furthermore, corresponding to the bowing component 30, a first limiting member 51 and a second limiting member 52 are provided on the body 10; by tightening the fastener 35, the restriction on the bowing component 30 is released, allowing the bowing component 30 to rotate around the fastener 35; when the bow is being used in the bowing groove 31, the bow is rotated to cause the bowing component 30 to rotate clockwise and counterclockwise around the fastener 35, and abut against the first limiting member 51 and the second limiting member 52, thereby limiting the rotation range of the bowing component 30.

[0053] Currently, widely used bow straighteners are fixed to the violin body, forming a 90° angle with the strings. They are used for practicing straight bowing but cannot change the angle, thus making them unsuitable for practicing advanced bowing techniques. The training device in this application not only allows for straight bowing practice but also enables angle-shifting (figure-eight) bowing practice. By tightening the fastener 35 to release the restriction on the bowing component 30, it is possible to rotate the bow during practice to perform figure-eight bowing. Specifically, when bowing out (playing a downbow), the bow frog points to the lower right, and the right hand gradually moves away from the player's body along a predetermined angle until the bow tip. When bowing in (playing an upbow), the bow tip points to the upper left, and the right hand gradually moves closer to the body along a predetermined angle until the bow frog, resulting in a figure-eight bow movement trajectory. Through repeated practice, muscle memory for the upward and downward bowing motion is achieved.

[0054] See Figure 2In a second specific embodiment, a muscle memory type violin basic skills standardization training device includes: a violin body 10 having a first end and a second end set opposite to each other; a 3D chin rest 20 mounted on the first end of the violin body 10 and whose position is adjustable; a mounting base 40 detachably mounted on the violin body 10 and located between the first end and the second end; a guide rod 41 mounted on the mounting base 40, the direction of the guide rod 41 being consistent with the bowing direction; and a sleeve-type right hand shape module 42 sleeved on the guide rod 41, the sleeve-type right hand shape module 42 being able to move back and forth on the guide rod 41.

[0055] See Figure 5 , Figure 6 as well as Figure 13 Furthermore, the training device also includes an index finger buckle 43 and a little finger buckle 44 that are movably and adjustablely installed on the top of the sleeve-type right hand module 42, a horsehair clip 48 installed on the bottom of the sleeve-type right hand module 42 and located between the index finger buckle 43 and the little finger buckle 44, and a thumb buckle 45 that is fixed to the bottom of the sleeve-type right hand module 42 and the horsehair clip 48 with a ferrule; the top surface of the index finger buckle 43 has a first groove 431; the top surface of the little finger buckle 44 has a second groove 441; and the middle part of the thumb buckle 45 has a positioning hole 451 that passes through the thumb buckle.

[0056] Preferably, the horse tail section 48 is located within the positioning hole 451.

[0057] See Figure 5 Furthermore, the index finger buckle 43 and the little finger buckle 44 are elastically fitted onto the top of the sleeve-type right hand shape module 42, and the position of the index finger buckle 43 and the little finger buckle 44 on the sleeve-type right hand shape module 42 can be easily adjusted according to the size of the hand.

[0058] Preferably, the index finger buckle 43 and the little finger buckle 44 are in the shape of arcs.

[0059] For violin playing, right-hand bowing is extremely important and also very difficult to master. Mastering the correct bow grip is an indispensable foundation for learning all right-hand techniques. Currently, bow grip aids sold on the market are grips that fix the finger joints. Although they can position each finger of the right hand correctly in appearance, because these grips fix all the finger joints of the right hand during practice, they cause the entire right hand to develop stiff muscle memory, resulting in stiffness and an inability to bow freely.

[0060] See Figure 5In this application, the first groove 431 of the index finger buckle 43 is used to position the right index finger, the second groove 441 of the little finger buckle 44 is used to position the right little finger, and the positioning hole 451 of the thumb buckle 45 is used to position the right thumb. The installation positions of the index finger buckle 43 and the little finger buckle 44 can be adjusted to accommodate different bow grips of different practitioners.

[0061] When in use, the practitioner holds the sleeve-type right hand shape module 42 with their right hand, pressing their right thumb on the positioning hole 451, their right index finger on the first groove 431, and their right little finger on the second groove 441. This helps the practitioner establish the correct bow grip posture with their right hand. Pushing the sleeve-type right hand shape module 42 allows it to move along the length of the guide rod 41, simulating the linear trajectory of the bow on the strings. This helps the practitioner practice bowing movements with the correct posture and repeat this action to form muscle memory.

[0062] See Figure 7 Preferably, the training device also includes a spherical right palm ball 46 and elastic ropes 47 attached to both sides of the right palm ball 46. In use, the elastic ropes 47 are looped around the right hand, so that the right palm ball 46 is located in the center of the right palm. This helps the right hand to form a natural fist shape, thereby allowing the other finger joints to be in a relaxed state that can flexibly extend and retract, so as to learn to use advanced bowing techniques with ease.

[0063] See Figure 8 In one specific embodiment, the top surface of the first end is provided with a receiving groove 111, and the training device also includes a connecting column 60 that is vertically movable and adjustablely installed on the first end and located in the receiving groove 111. The top end of the connecting column 60 extends out of the top surface of the first end to form a support portion; the 3D chin rest 20 is slidably disposed on the support portion.

[0064] See Figure 8Furthermore, the training device also includes a mounting member 112 that passes through the bottom surface of the first end and is mounted on the first end. The mounting member 112 includes an end head 1121 and a screw part 1122. The screw part 1122 extends into the receiving groove 111. The bottom surface of the connecting post 60 is provided with a connecting hole. A nut 114 is embedded in the opening of the connecting hole on the connecting post 60. The screw part 1122 is threaded into the nut 114 and extends into the connecting hole. A washer 115 is fitted on the screw part 1122 and is placed at the bottom of the receiving groove 11. By rotating the mounting member 112, the length of the part of the screw part 1122 extending into the connecting hole is adjusted, thereby clamping and fixing the washer 115 between the end head 1121 and the nut 114, thereby locking and fixing the connecting post 60 to the first end. Before locking, the connecting post 60 can be raised by selecting a shim 115 of appropriate thickness or by stacking multiple shims 115, thereby achieving vertical movement adjustment of the connecting post 60.

[0065] Preferably, the bottom surface of the first end is provided with a mounting hole 101 that is compatible with the mounting member 112.

[0066] Specifically, mounting part 112 is an internal hex screw, which can be adjusted with a hex wrench.

[0067] By selecting a shim 115 of appropriate thickness or stacking multiple shims 115 under the connecting post 60, the connecting post 60 can be vertically moved and adjusted, thereby adjusting the height of the 3D chin rest 20 to suit the neck length of different learners. Before locking the connecting post 60, the 3D chin rest 20 can be rotated and adjusted to suit the direction of the headstock (i.e., the orientation of the second end). After adjusting the angle, the connecting post 60 is locked and fixed by rotating the adjusting mounting piece 112 to prevent the 3D chin rest 20 from rotating. By sliding the 3D chin rest 20, the position of the 3D chin rest 20 on the support part can be adjusted, thereby achieving horizontal movement adjustment of the 3D chin rest 20 to suit the learner's chin holding position. This application can achieve a large and precise three-dimensional position and posture adjustment of the 3D chin rest 20 in the vertical direction, horizontal direction, and rotation angle, thereby adjusting the 3D chin rest 20 to the most suitable state according to the learner's needs and avoiding shoulder and neck problems caused by discomfort caused by the 3D chin rest 20.

[0068] See Figure 8Furthermore, the bottom surface of the 3D chin rest 20 is provided with a groove 21, and an opening is formed on the side of the 3D chin rest 20 in the groove 21. The setting direction of the groove 21 is consistent with the length direction of the 3D chin rest 20. The training device also includes an adjusting rod 22 with one end rotatably mounted on the groove wall of the groove 21 and a slider 61 slidably disposed in the groove 21 and sleeved and threadedly connected to the adjusting rod 22. The setting direction of the adjusting rod 22 is consistent with the length direction of the groove 21. The bottom surface of the slider 61 is mounted on the support part. By rotating the adjusting rod 22, the adjusting rod 22 can move relative to the slider 61 to realize the movement adjustment of the 3D chin rest 20. That is, the 3D chin rest 20 can be precisely moved and adjusted along the setting direction of the adjusting rod 22.

[0069] Preferably, the adjusting rod 22 is a Phillips head screw, and a screwdriver is inserted into the slide groove 21 from the opening to rotate and adjust the adjusting rod 22.

[0070] See Figure 8 Preferably, the receiving slots 111 are two located on both sides of the first end. By selecting the corresponding receiving slot 111 to install the connecting post 60, a large range of horizontal position adjustment of the 3D chin rest 20 can be achieved. By rotating the adjusting rod 22, a small range of precise horizontal movement adjustment of the 3D chin rest 20 can be achieved.

[0071] See Figure 1 In this embodiment, the body 10 includes a first plate 11, a second plate 12, and a telescopic rod 13 that is installed and connected between the first plate 11 and the second plate 12 and is telescopically adjustable; the 3D chin rest 20 is adjustablely installed on the first plate 11.

[0072] Preferably, the receiving groove 111 is provided on the top surface of the first plate 11.

[0073] The length of the violin body 10 can be adjusted by telescopic adjustment rod 13 to fit the specifications of fractional violins to 4 / 4 adult violins (excluding toy violins), making it suitable for basic skill training for violin and viola learners from young children to adults (arm length 35.5cm to 58cm and above), with a wider range of applications.

[0074] See Figure 1 The telescopic rod 13 includes two fittings 131 that fit together. The telescopic length of the telescopic rod 13 can be adjusted by adjusting the length of the overlapping portion of the two fittings 131. Preferably, the fittings 131 can be connected by a compression fitting or by a threaded connection or other installation methods.

[0075] See Figure 1 and Figure 3Furthermore, the training device also includes a support 50 sleeved on the telescopic rod 13 and a locking member 54 threaded onto the support 50 and passing through the telescopic rod 13. The end of the locking member 54 extends into the support 50 and abuts against the telescopic rod 13, thus fixing the support 50 to the telescopic rod 13. After releasing the locking member 54 from its position, the position and angle of the support 50 on the telescopic rod 13 can be adjusted as needed by moving the support 50. Preferably, the locking member 54 is a bolt. See also... Figure 2 The mounting base 40 is detachably mounted on the support 50. See also Figure 1 The bow-carrying component 30 is detachably mounted on the mounting base 40 by fasteners 35.

[0076] See Figure 1 and Figure 2 This application utilizes a detachable design for the bowing component 30 and the mounting base 40, enabling two modes of practice. When only the bowing component 30 is installed, the bow can be used directly on the bowing slot 31 for straight-line and angle-changing bowing practice. When only the mounting base 40 is installed, by moving the sleeve-type right-hand shaping module 42, the module moves on the guide rod 41 to simulate the bow's trajectory on the strings. This helps the practitioner practice the coordination of various movements of the right forearm, wrist, and fingers during bowing with the correct posture, thus forming correct muscle memory.

[0077] See Figure 3 Furthermore, the first limiting member 51 and the second limiting member 52 are inverted L-shaped. The first limiting member 51 and the second limiting member 52 are respectively disposed on both sides of the top surface of the support 50 and are arranged opposite to each other. A first slot 511 is formed between the first limiting member 51 and the top surface of the support 50, and a second slot 521 is formed between the second limiting member 52 and the top surface of the support 50.

[0078] See Figure 3 and Figure 4 The mounting base 40 is frustoconical in shape. At its bottom end, a first connector 401 is provided corresponding to the first slot 511, and a second connector 402 is provided corresponding to the second slot 521. The first connector 401 and the second connector 402 are positioned opposite each other and flush with the bottom surface of the support 50. The support 50 is detachably mounted on the mounting base 40 by inserting and engaging the first connector 401 into the first slot 511 and the second connector 402 into the second slot 521. Preferably, the first limiting member 51 and the second limiting member 52 are arranged along the entire length of the corresponding side of the support 50.

[0079] See Figure 3 and Figure 4Furthermore, the training device also includes a third limiting member 53, which is mounted on the top surface of the support 50 and is in the shape of an inverted L. The third limiting member 53 is connected between the first limiting member 51 and the second limiting member 52. The first limiting member 51, the second limiting member 52, and the third limiting member 53 are connected to form a U-shape and are located at the edge of the mounting base 40. A third slot 531 is formed between the third limiting member 53 and the top surface of the support 50. The third slot 531 communicates with the first slot 511 and the second slot 521.

[0080] The bottom end of the mounting base 40 is provided with a third connector 403 that is flush with the bottom surface of the mounting base 40, corresponding to the third slot 531. The third connector 403 is installed and connected between the first connector 401 and the second connector 402. The first connector 401, the second connector 402 and the third connector 403 are connected to form a C-shape.

[0081] See Figure 3 and Figure 4 When mounting the base 40, insert both ends of the third connector 403 into the first slot 511 and the second slot 521 respectively, and move the base 40 toward the third slot 531. As the base 40 moves, the first connector 401 is inserted into the first slot 511 and the second connector 402 is inserted into the second slot 521. When the third connector 403 is inserted and snapped into the third slot 531, the first connector 401 is completely snapped into the first slot 511 and the second connector 402 is completely snapped into the second slot 521. This structure makes the installation and removal of the base 40 more convenient and enhances the stability of the base 40 installation.

[0082] See Figure 1 and Figure 3 In one specific embodiment, the bow-carrying component 30 includes a base plate 32 mounted on a support 50, a vertical plate 33 mounted on the base plate 32, and a guide tube 34 mounted on the top of the vertical plate 33. The top surface of the guide tube 34 has an opening extending along its length to communicate with the internal space of the guide tube 34. The bow-carrying groove 31 is formed through the internal space of the guide tube 34 and the opening. The bow-carrying component 30 is mounted on the support 50 by fasteners 35 passing vertically through the base plate 32 and the support 50.

[0083] See Figure 3 Preferably, the base plate 32 is semi-circular in shape and has through holes for fasteners 35 to pass through. In the tightened state, the base plate 32 is clamped and fixed between the top of the fastener 35 and the top surface of the support 50. By tightening the fastener 35, the distance between the top of the fastener 35 and the top surface of the support 50 is increased to release the clamping restriction on the base plate 32, so that the base plate 32 can rotate around the fastener 35.

[0084] Specifically, fastener 35 is a bolt.

[0085] See Figure 1 and Figure 11 In this embodiment, the training device further includes a fixing rod 14 installed on the second end and whose setting direction is consistent with the setting direction of the instrument body 10, a left hand shape module 70 sleeved on the fixing rod 14, a palm support 71 installed on one side of the left hand shape module 70, and a thumb baffle 72 erected on the left hand shape module 70 and located on the other side of the left hand shape module 70; the top surface of the left hand shape module 70 is provided with a plurality of recesses 702 at intervals along the length direction of the left hand shape module 70.

[0086] Preferably, the fixing rod 14 is mounted on the end face of the second plate 12 away from the first plate 11.

[0087] "Rudder-like movement" refers to the left-hand arm movement where, when holding the violin, the elbow is bent under the back of the violin. As the fingers move across the fingerboard, the elbow should swing naturally from side to side as the instrument changes strings from bass to treble (G, D, A, E) or vice versa, much like a rudder on a ship. This rudder-like movement is difficult for beginners to master, easily causing them to be unable to press the strings correctly and hindering their movement on the neck for shifting positions.

[0088] When using this application, the practitioner holds the left-hand hand shape module 70 with their left hand, palm covering the palm rest, and the left thumb pressing on the thumb guard 72 to prevent the thumb from gripping the neck too tightly and causing tension in the left hand. The remaining fingers of the left hand press on the corresponding recesses 702 to control the correct fingering position. By rotating the left-hand hand shape module 70, the arm swings left and right, thus enabling muscle memory training of the steering wheel-like motion.

[0089] The violin has more than thirteen positions. When playing the violin, it is usually necessary to shift between positions. During the shifting process, the player's left hand will move back and forth on the violin. The posture of the left hand may change during the movement. It is quite difficult for beginners to master the correct fourth frame hand shape.

[0090] When using this application, the practitioner holds the left hand shape module 70 with their left hand, and after correctly positioning each finger and posture of the left hand through the thumb baffle 72 and the concave hole 702, they can perform muscle memory training for low-grip shifting by moving the left hand shape module 70 back and forth along the length of the fixed rod 14.

[0091] See Figure 11 and Figure 12Furthermore, a plurality of locking holes 701 are provided at intervals along the length of the left hand shape module 70 on one side. The palm support 71 is provided with a locking member 711, which is inserted into and locked into the locking hole 701 to install the palm support 71 onto the left hand shape module 70. By selecting the appropriate locking hole 701 to install the palm support 71, the needs of different practitioners for left-hand grip can be accommodated.

[0092] Ideally, the palm support 71 should be semi-circular.

[0093] See Figure 1 and Figure 2 In this embodiment, the training device also includes a dot laser emitting positioner 80 installed on the second end and capable of emitting laser. The dot laser emitting positioner 80 is set in the same direction as the body 10 and the emitting head of the dot laser emitting positioner 80 is set facing outward from the body 10.

[0094] Preferably, the dot laser emitting positioner 80 is mounted on the end of the fixing rod 14 away from the second plate 12.

[0095] Before training, the practitioner adjusts the posture of the instrument body 10 and activates the dot laser emitter locator 80. The laser emitted by the dot laser emitter locator 80 is projected onto the wall, marking the position of the laser beam. During training, by observing whether the laser deviates from the marked position, the practitioner can determine whether the instrument body 10 is level and at the correct angle, and adjust the height and left and right of the instrument body 10 in a timely manner to ensure that the laser is always aligned with the marked position during the performance, thus ensuring that the practitioner always keeps the instrument body level and at the correct angle.

[0096] See Figure 9 and Figure 10 In one specific embodiment, a fixing hole 121 is provided on the end face of the second plate 12 away from the first plate 11, and a through hole 122 is provided through the second plate 12 along the length direction of the second plate 12, the through hole 122 communicating with the fixing hole 121. One end of the telescopic rod 13 is provided with a fixing plate 132 adapted to the fixing hole 121, the telescopic rod 13 passes through the through hole 122, and the fixing plate 132 is threaded into the fixing hole 121 to fix the telescopic rod 13 to the second plate 12. The other end of the telescopic rod 13 extends out of the second plate 12 and into the first plate 11 and is threaded into the first plate 11.

[0097] See Figure 10 Preferably, the fixing plate 132 is provided with a threaded hole 1321, and the end of the fixing rod 14 near the second plate 12 is threaded into the threaded hole 1321 of the fixing plate 132.

[0098] See Figure 1and Figure 2 In one specific embodiment, the training device further includes a shoulder pad 90, the top surface of which is provided with a slot 113 extending laterally, and the shoulder pad 90 is secured to the bottom end of the first end through the slot 113.

[0099] This application features a detachable shoulder pad 90, which allows for adjustments based on individual shoulder width, neck length, and 3D chin rest interaction. The shoulder pad 90 can be positioned appropriately on the first end. Furthermore, users can choose to install or not install the shoulder pad 90 according to their usage habits, maintaining the optimal posture and condition for holding the instrument, making it more flexible and convenient.

[0100] join Figure 1 and Figure 2 Preferably, the training device also includes a mounting groove on the side of the second plate 12 and near the left hand shape module 70, and a side plate strip 15 with its end locked in the mounting groove. When the left hand holds the left hand shape module 70 and moves, the left hand can no longer move towards the 3D chin rest 20 when it reaches the side plate strip 15, so as to help the trainee develop the correct grip feel.

[0101] By adopting the above technical solution, the present invention has the following beneficial effects:

[0102] This invention features an adjustable 3D chin rest 20 on the instrument body 10. The chin rest 20 can be moved and adjusted to a suitable position according to the user's needs, ensuring a more relaxed and comfortable playing experience. This avoids excessive force or improper posture caused by using the jaw and shoulders, which can lead to problems in the cervical spine, jaw, and shoulder muscles. The first groove 431, second groove 441, and positioning groove 453 help the right hand establish a correct bow-holding posture, while the thumb guard 72, concave hole 702, palm support 71, and right palm ball 46 help the left hand establish a correct grip posture. This training device is used for muscle memory training of various bowing techniques (full bow and half-bow) and right-hand finger jellyfish movements (jellyfish-like motion). An angle-changing bowing device is used for figure-eight bowing training and various right-hand muscle memory training exercises.
