Description

TECHNICAL FIELD

[0001] The present scheme relates to the technical field of music teaching, in particular to a two-stringed Chinese violin auxiliary rubbing string device. BACKGROUND

[0002] The two-stringed Chinese violin originated in the Tang Dynasty and is also known as "Xi Qin". It has a history of more than a thousand years. It is a traditional Chinese plucked string instrument. The two-stringed Chinese violin has a sound similar to human voice and is singing and expressive.

[0003] During playing, the performer needs to hold a bow with one hand and move it back and forth on the strings, and hold the two-stringed Chinese violin with the other hand to adjust the scale by rubbing, pressing and sliding the strings.

[0004] As the saying goes, "thousand days of two-stringed Chinese violin and hundred days of bamboo flute", the two-stringed Chinese violin is one of the most difficult traditional Chinese instruments. It is extremely difficult for beginners to learn. Many people encounter bottlenecks at the initial stage and find it difficult to make standard gestures. Especially when rubbing the strings, the movements are stiff and the coordination of different parts is not harmonious.

[0005] Chinese Patent Publication No. CN202121190890.9, published on December 7, 2021, is entitled two-stringed Chinese violin pitch auxiliary device. The application discloses a two-stringed Chinese violin pitch auxiliary device, which includes a two-stringed Chinese violin body, a two-stringed Chinese violin neck fixedly connected to the inside bottom of the two-stringed Chinese violin body, a handle fixedly installed on the upper end of the two-stringed Chinese violin neck outside the two-stringed Chinese violin body, an adjusting rod detachably installed on the outer end of the two-stringed Chinese violin neck, an audio marker detachably installed on the outer end of the adjusting rod, a locking ring threadedly connected to the outer end of the audio marker, and a pressing surface fixedly provided on the front end of the audio marker. The two-stringed Chinese violin pitch auxiliary device can position the pitch, visualize the pitch, solve a big problem for beginners, and make it easy to start. The unique design of the audio marker is not a closed loop but an open loop, which does not affect the tiger mouth on the opposite side of the neck to slide back and forth. The indicated shape not only plays a marking role but also does not affect the fingers to slide back and forth, which is convenient and practical.

[0006] The above-mentioned patent discloses a pitch auxiliary device, which is used to assist in pitch practice. However, during the two-stringed Chinese violin performance, rubbing the strings is a skillful action, which requires the first finger (index finger) to be bent, the second finger (middle finger) to be slightly bent, and the third finger (ring finger) to be basically straight. This is very difficult for beginners or two-stringed Chinese violin enthusiasts to learn.

[0007] Therefore, a two-stringed Chinese violin auxiliary device is needed to standardize the finger position of beginners, assist beginners in making rubbing string movements, have a simple structure, be easy to assemble and disassemble, and have a good matching degree. SUMMARY

[0038] The present solution will be further described below with reference to the accompanying drawings and embodiments:

[0039] Example 1:

[0040] A vibrato aid device for erhu, such as Figures 1-3 As shown, an auxiliary vibrato device for erhu includes an auxiliary device body 1.

[0041] The auxiliary device body 1 includes a palm rest 4 located at the top rear end, a contoured connecting opening 5 in the middle, and a vibrato auxiliary end 3 at the front end.

[0042] The vibrato auxiliary end 3 includes a first vibrato auxiliary end 31, a second vibrato auxiliary end 32, and a third vibrato auxiliary end 33, from top to bottom.

[0043] In this design, the contoured connection opening 5 of the auxiliary device body 1 is a semi-circular arc-shaped opening structure that matches the cylindrical structure of the piano neck. The top rear end of the opening extends outward to form the palm rest 4. A tensioning structure 2 is provided on the extension portion of the contoured connection opening 5 towards the front end.

[0044] The tightening / loosening structure 2 specifically consists of symmetrically arranged screw holes 22, which are locked and fixed by bolts 21. It includes at least one bolt 21, which is used to tighten or loosen the contoured connection opening 5, thereby fixing the auxiliary device body 1 to the erhu neck.

[0045] After the bolt 21 passes through the screw hole, it locks the contour connection opening 5.

[0046] As a preferred option, the inner wall of the contoured connection opening 5 can be provided with an anti-slip layer or a protective layer, such as a silicone pad, which can effectively prevent the structure from sliding after it is fixed.

[0047] At the same time, the silicone pad also protects the neck from damage when it is locked.

[0048] In this embodiment, three bolts 21 are provided;

[0049] That is, the auxiliary device body 1 also includes three screw holes symmetrical to the bolt 21, so as to fix it in the upper, middle and lower positions, and the fixing effect is better.

[0050] Specifically, the auxiliary device body 1 is fitted onto the neck of the erhu. During the fitting process, the auxiliary device body 1 is made of plastic. Due to the material properties of plastic, the opening of its contoured connection opening 5 has the ability to deform, thus allowing it to be inserted into the neck. After it is fixed, the opening of the contoured connection opening 5 faces the string surface, making it convenient for the vibrato auxiliary end 3 to assist in the vibrato action.

[0051] The screw passes through the screw hole 22 and is fixed by the bolt 21, with adjustable tightness.

[0052] With the addition of tension and loosening structure 2, it is adaptable to different erhu necks, and its simple structure allows for easy assembly and disassembly.

[0053] In this solution, the auxiliary device body 1 is made of soft plastic, and in this embodiment, it is made of PE plastic material, which has good stability.

[0054] like Figure 2 As shown, the palm rest 4 is disposed on the upper end of the auxiliary device body 1.

[0055] Specifically, the palm support 4 supports the palmar muscles and the metacarpophalangeal joint of the thumb, with the tip of the thumb suspended in the air.

[0056] Specifically, the palm support 4 includes a tiger's mouth palm support part 41 and a thumb support part 42. The tiger's mouth palm support part 41 supports the palm muscle position and places the tiger's mouth at the contoured connecting opening 5.

[0057] The thumb support 42 supports the thumb.

[0058] In this plan, as follows Figures 1-4 As shown, the vibrato auxiliary end 3 is arranged in a stepped manner, with the slope gradually becoming gentler from top to bottom. The vibrato auxiliary end is similar to the degree of finger bending. When the index finger is placed on the first vibrato auxiliary end 31, it exhibits a relatively large bend.

[0059] Place the middle finger on the second vibrato auxiliary end 32, and bend it slightly after placement.

[0060] The ring finger is placed on the third vibrato auxiliary end 33, and remains basically vertical after placement.

[0061] The vertical plane AA connecting the vibrato auxiliary end 3 and the auxiliary device body 1 is taken as the measuring plane, specifically the surface of the front opening extension and the vibrato auxiliary end 3 (actually an integral structure). For the convenience of structural description, this measuring plane is introduced here.

[0062] The vertical surface connecting the vibrato auxiliary end and the auxiliary device body is the measuring surface;

[0063] The first vibrato auxiliary end (31) has a width B1 of 1.7-2.2 cm, a height H1 of 1-1.5 cm, and a height H2 of 0.4-0.6 cm.

[0064] The second vibrato auxiliary end (32) has a width B2 of 2.5-3cm and a height H3 of 0.7-0.9cm.

[0065] The width of the third vibrato auxiliary end (33) is B3: 1.3~1.7cm, and the height is H4: 0.2~0.3cm.

[0066] In this embodiment,

[0067] The first vibrato auxiliary end (31) has a width B1 of 2cm, a height H1 of 1cm, and a height H2 of 0.6cm.

[0068] The second vibrato auxiliary end (32) has a width B2 of 3cm and a height H3 of 0.8cm.

[0069] The third vibrato auxiliary end (33) has a width B3 of 1.5cm and a height H4 of 0.3cm.

[0070] This size selection can match the hand size of the vast majority of learners, making it more versatile.

[0071] The vibrato auxiliary end 3 provided in this solution has a reasonable size design that conforms to the standard hand shape of vibrato action, so that beginners can quickly master the standard vibrato gesture.

[0072] Specifically, during practice, place the index finger on the first vibrato auxiliary end 31, the middle finger on the second vibrato auxiliary end 32, and the ring finger on the third vibrato auxiliary end 33. By lifting and lowering the fingertips on the corresponding vibrato auxiliary ends 3, the fingertips make vibrato movements on the strings, forming a standardized vibrato practice action.

[0073] Furthermore, during vibrato practice, the fingertips are forcibly limited by the first to third vibrato auxiliary ends, meaning the fingertips are in contact with the vibrato auxiliary ends. As a result, the finger movements must form a downward pressing motion, rather than the horizontal pressing motion often made by beginners. Therefore, during vibrato practice, the fingertips can effectively move up and down to contact the vibrato auxiliary ends, thus practicing the lifting and lowering motion of vibrato, achieving the purpose of posture correction, rapid learning, and standardized movements.

[0074] The vibrato assist end 3 provided in this solution has a stepped design. The slope standardizes finger placement and helps beginners quickly master the operation of vibrato, reducing the difficulty of learning.

[0075] In this design, the erhu auxiliary vibrato device is made of soft plastic. In this embodiment, it is made of PE plastic, which has good stability.

[0076] To further explain, based on its usage mechanism, a method for assisting vibrato on the erhu is as follows:

[0077] S1. The erhu auxiliary vibrato device is fitted onto the outside of the erhu and fixed based on the elasticity structure;

[0078] The auxiliary device body 1 is fitted onto the neck of the erhu, with its opening facing the string surface. Screws pass through the screw holes 22 and are fixed and adjusted by the bolts 21.

[0079] S2, palm and thumb, fixed based on palm support;

[0080] After installation, the palm support 4 supports the palmar muscles and the metacarpophalangeal joint of the thumb, with the tip of the thumb suspended in the air.

[0081] S3, index finger, middle finger and ring finger, the fingertip position is determined based on the vibrato auxiliary end;

[0082] When playing, place your index finger on the first vibrato auxiliary end 31, your middle finger on the second vibrato auxiliary end 32, and your ring finger on the third vibrato auxiliary end 33.

[0083] S4. The fingertip makes a vibrato motion by lifting and lowering the fingertip on the vibrato assist end.

[0084] When playing, the fingertips lift and drop on the corresponding vibrato auxiliary end 3, and the fingertips make a vibrato motion on the strings.

[0085] In summary, the vibrato aid 3 provided in this application, by standardizing finger placement through slope, helps beginners quickly master the operation of vibrato and reduces the difficulty of learning.

[0086] The tensioning structure 2 provided in this application has the ability to adapt to different erhu necks, and its structure is simple and can be easily installed and removed.
