Description

Technical Field

[0001] This invention relates to the field of Morin Khuur (horsehead fiddle) technology, and more specifically, to a cluster-type rapid string-changing device and method for Morin Khuur. Background Technology

[0002] The Morin Khuur is a traditional bowed string instrument of the Mongolian people. Its strings have a bundled structure, which is the core component that ensures the Morin Khuur's intonation and tone. Similar bowed string instruments, such as the Chaoer, also use the same string structure. In the daily use and maintenance of the Morin Khuur, string replacement is a necessary operation. Currently, changing Morin Khuur strings requires the use of multiple tools such as scissors, combs, lighters, and tuning forks. The basic string replacement process is as follows: tie the strings to the bow plate → repeatedly comb the strings with a comb (the finest teeth of existing combs are still too wide for Morin Khuur strings, resulting in poor combing effect) → use a tuning fork to wind the strings from bottom to top → tie two to three strings together tightly → trim the base of the strings with scissors → heat the strings with a lighter.

[0003] The aforementioned traditional string-changing method has many drawbacks: First, the steps are cumbersome, with a single string change taking 15 to 30 minutes or even longer, and independent string changing usually requires two people to cooperate, making it difficult for a single person to operate; Second, any mistake in the operation will cause the strings to produce noise and the tone to deteriorate, and long-term use of improperly replaced strings will also cause the tone of the morin khuur itself to gradually deteriorate; Third, due to the high difficulty of string changing, most morin khuur learners and players choose to "avoid changing strings unless necessary," and this wrong habit not only affects the player's technical progress but also reduces the player's sensitivity to pitch and tone.

[0004] The core reason why the industry has not yet solved the above-mentioned technical problems is that although the history of the Morin Khuur can be traced back to the Tang Dynasty, the modern Morin Khuur has only become truly professional and stage-oriented in the last 60 years. The development and inheritance time is relatively short. Most practitioners focus more on improving their playing skills when learning to play the Morin Khuur, and rarely carry out research and development of Morin Khuur-related products. As a result, there is still no string-changing device specifically for the Morin Khuur on the market, which has created a technical gap in the industry. Summary of the Invention

[0005] This invention addresses the numerous shortcomings of existing Morin Khuur (horsehead fiddle) string-changing methods by providing a clustered, rapid string-changing device and method. Its primary objective is to integrate all the necessary functions and tools for Morin Khuur string changing, significantly lowering the technical barrier and enabling a single person to quickly complete the string-changing operation. Secondly, it ensures the tone and volume of the strings after changing, fundamentally solving problems such as unwanted noise and wolf tones that occur after string installation, and preventing damage to the Morin Khuur's tone due to improper string changing. Simultaneously, this invention aims to reduce the consumption and time costs of Morin Khuur string changing, making the device both portable and decorative, with low manufacturing costs. It fills the market gap for dedicated Morin Khuur string-changing devices, promoting the inheritance and development of the Morin Khuur intangible cultural heritage.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: On one hand, the present invention provides a clustered morin khuur (horsehead fiddle) quick string changing device, including an upper cover and a lower cover. The upper cover and the lower cover are hinged at the rear by an elastic hinge assembly, and the two are detachably fastened together at the front by a snap-fit ​​assembly. The lower cover has a clustering assembly, a dispersing assembly and a comb assembly arranged sequentially from left to right inside. The upper cover has an adjustable elastic anti-slip clip on its outer side. The clustering assembly includes two sets of clustering units, which are respectively installed on the inner side of the upper cover and the inner side of the lower cover, with their positions corresponding to each other. The dispersion assembly includes a lower dispersion plate and an upper dispersion plate. The upper dispersion plate is located inside the upper cover, and the lower dispersion plate is located inside the lower cover. The upper and lower dispersion plates are positioned opposite each other. The upper end of the lower dispersion plate has a conical structure, and the upper dispersion plate has a locking groove inside that is adapted to the lower dispersion plate. The comb assembly includes a front comb array and a rear comb array, both of which are composed of multiple arrayed comb bars.

[0007] Furthermore, both the upper and lower covers are provided with positioning slots A and B. The bottom of the clustering unit is inserted into the positioning slot A and fixed with fastening screws. The upper dispersing plate is inserted into the positioning slot B on the upper cover and fixed with fastening screws. The lower dispersing plate is inserted into the positioning slot B on the lower cover and fixed with fastening screws.

[0008] Furthermore, the front comb tooth array is located in the area between the upper gathering unit and the lower dispersing plate on the lower cover, and the rear comb tooth array is located in the area to the right of the upper and lower dispersing plates on the lower cover; the comb bar density of the left half of the rear comb tooth array is less than the comb bar density of the right half.

[0009] Furthermore, the lower cover has a stepped positioning groove for installing the combing bar inside. The bottom of the combing bar is fixed with a bracket, the diameter of which is larger than the diameter of the combing bar. The combing bar is detachably inserted into the stepped positioning groove from the web.

[0010] Furthermore, a bottom groove is provided at the bottom of the lower cover, and the bottom groove is connected to the bottom of the stepped positioning through groove; a bottom cover is installed inside the bottom groove, and the bottom cover is detachably connected to the bottom groove by fastening screws.

[0011] Furthermore, the clustering unit includes a clustering block, a clustering slot, a clustering cavity, and a limiting arm; the bottom of the clustering block is engaged in the positioning slot A, and the front and rear sides of the clustering block are provided with limiting arms, which are in the shape of an "eight"; a clustering cavity is opened on the upper surface of the clustering block, and a clustering slot is opened on the left side of the clustering cavity and communicates with it, and the clustering slot communicates with the left end face of the clustering block.

[0012] Furthermore, the lower dispersion plate is provided with baffle strips on both the front and rear sides, and the upper end surface of the baffle strips is higher than the top surface of the lower dispersion plate; the upper dispersion plate is provided with docking baffles on both the front and rear sides, and after the upper dispersion plate and the lower dispersion plate are closed and connected, the docking baffles and the baffle strips are in contact and connected.

[0013] Furthermore, the hinge assembly includes a hinge seat, a hinge joint, a torsion spring, and a pin; the hinge seat is located inside the lower cover, the hinge joint is located inside the upper cover, the hinge joint and the hinge seat are rotatably connected by a pin, and a torsion spring is sleeved on the pin, one end of the torsion spring abuts against the upper cover, and the other end abuts against the lower cover.

[0014] Furthermore, the snap-fit ​​assembly includes an elastic snap-fit ​​plate, snap teeth, and snap-fit ​​groove; the elastic snap-fit ​​plate is made of elastic plastic sheet and is disposed on the front end face of the upper cover, on which a snap-fit ​​groove is provided; the snap teeth are fixed on the front end face of the lower cover; after the upper cover and the lower cover are closed, the snap teeth are snapped into the snap-fit ​​groove.

[0015] On the other hand, the present invention provides a string-changing method using the aforementioned clustered morin khuur (horsehead fiddle) rapid string-changing device, comprising the following steps: Step 1: First, fix one end of the morin khuur string to the morin khuur, open the device and place it on the end of the string, insert the lower cover from one side of the morin khuur string into the bottom of the morin khuur string, and insert the morin khuur string into the clustering slot of the clustering assembly. Step 2: Spread the strings of the morin khuur and pass them through the front comb array. Then, pass the spread strings over the lower scattering board and guide them over the right-side rear comb array. Step 3: Press the top cover to close it with the bottom cover, and the upper and lower distribution plates will engage. The closing of the upper and lower distribution plates will cause the strings to spread evenly along the lower distribution plate, and at the same time, the evenly spread strings will be inserted into the back comb array. Step 4: Keep the upper and lower covers closed, and use your fingers to control the tightening force on the strings. Move the device to comb the strings. Step 5: Repeat steps 1-4 1-3 times to ensure the strings are combed flat and free of tangles; Step 6: When combing the strings for the last time, stop the device at the end of the string and press it down to fix the shape; Step 7: Trim and twist the base of the string, and then fix that end of the string to the morin khuur to complete the string change.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The string changing device of the present invention integrates multiple functions such as gathering, combing, dispersing and shaping required for changing the strings of the morin khuur, replacing multiple tools such as combs and tuning forks required for traditional string changing. It does not require the cooperation of multiple people and enables a single person to complete the string changing operation independently, which greatly reduces the technical threshold of changing the strings of the morin khuur. The time for a single string changing can be shortened to within 5 minutes, which significantly improves the efficiency of string changing.

[0017] 2. This invention achieves the gradual combing and precise arrangement of clustered strings through the coordinated cooperation of the clustering component, the dispersing component, and the comb tooth component. The density design of the rear comb tooth array is more in line with the combing pattern of the strings, ensuring the accuracy of the string arrangement after string changing. It fundamentally solves the problems of noise and wolf tone caused by improper string arrangement in traditional string changing, while avoiding damage to the tone of the morin khuur due to string changing errors, thus ensuring the performance and service life of the morin khuur.

[0018] 3. All components of the device of the present invention adopt a detachable connection method, which makes it convenient to replace the appropriate clustering unit, dispersing plate and combing bar according to different specifications of morin khuur strings, and the device has strong versatility; at the same time, the overall structure of the device is compact, and the elastic anti-slip clip on the outside of the top cover improves the ease of holding. The device is both portable and decorative, and can be carried as a matching small accessory for morin khuur.

[0019] 4. The device of this invention is made of conventional materials such as plastic and metal, and the manufacturing process is simple and the production cost is low. The string changing method is clear and the operator can master it after simple learning. It reduces the time and cost of changing strings for the morin khuur, solves the pain point of "not changing strings unless necessary" in the industry, and helps to improve the pitch and tone sensitivity of morin khuur learners and performers, and promotes the dissemination and development of morin khuur playing technology.

[0020] 5. This invention fills the industry gap of having no dedicated string changing device for the Morin Khuur, enriches the peripheral supporting product system for the Morin Khuur, provides hardware support for the inheritance and development of the Morin Khuur intangible cultural heritage, and also provides a reference idea for the research and development of string changing devices for similar clustered string bowed instruments.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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.

[0037] Example 1: As Figures 1 to 12 As shown, this embodiment provides a clustered morin khuur (horsehead fiddle) quick string changing device, which is made of lightweight and wear-resistant plastic material and includes an upper cover 1 and a lower cover 2. The upper cover 1 and the lower cover 2 are hinged at the rear by an elastic hinge assembly 8, and their front sides are detachably fastened together by a snap-fit ​​assembly 7. The hinge assembly 8 enables the opening and closing of the upper cover 1 and the lower cover 2, and the snap-fit ​​assembly 7 enables them to be fixed after opening and closing, thus meeting the closing and pressing requirements during the string combing process. The lower cover 2 has a clustering assembly 3, a dispersing assembly 5 and a combing assembly arranged from left to right inside, which respectively realize the functions of clustering and guiding the strings, dispersing them evenly, and combing and shaping them. The upper cover 1 has an adjustable elastic anti-slip clip 9 on its outer side, which makes it easy to attach the string changing device to the instrument, making it easy to carry and also having a decorative effect.

[0038] Furthermore, the clustering assembly 3 includes two clustering units, which are respectively installed inside the upper cover 1 and the lower cover 2. The two units are positioned opposite each other. After the upper cover 1 and the lower cover 2 are closed, the two clustering units form a closed clustering space, which realizes the centralized introduction and positioning of the clustered strings of the morin khuur, and avoids the strings from becoming scattered in the early stage of combing.

[0039] In addition, the dispersion component 5 includes a lower dispersion plate 53 and an upper dispersion plate 54. The upper dispersion plate 54 is located inside the upper cover 1, and the lower dispersion plate 53 is located inside the lower cover 2. The upper dispersion plate 54 and the lower dispersion plate 53 are positioned correspondingly. The upper end of the lower dispersion plate 53 has a conical structure. The upper dispersion plate 54 has a locking groove 55 that is adapted to the lower dispersion plate 53. When the upper cover 1 and the lower cover 2 are closed, the conical structure of the lower dispersion plate 53 is engaged in the locking groove 55 of the upper dispersion plate 54, so that the bundled strings are evenly dispersed along the conical structure, laying the foundation for subsequent fine combing.

[0040] Furthermore, the comb assembly includes a front comb array 4 and a rear comb array 6. Both the front comb array 4 and the rear comb array 6 are composed of multiple arrays of combing rods 62. The combing rods 62 are spaced apart to comb the strings and prevent the strings from getting tangled or overlapping.

[0041] In this embodiment, both the upper cover 1 and the lower cover 2 are provided with positioning slots A31 and B51. The bottom of the clustering unit is inserted into the positioning slot A31 and fixed by the fastening screw 11, so as to realize the detachable installation of the clustering unit and facilitate the replacement and maintenance of the clustering unit. The upper dispersing plate 54 is inserted into the positioning slot B51 on the upper cover 1 and fixed by the fastening screw 11, and the lower dispersing plate 53 is inserted into the positioning slot B51 on the lower cover 2 and fixed by the fastening screw 11. Similarly, the dispersing component 5 is detachable and can be installed, and the appropriate dispersing plate can be replaced according to the different specifications of the morin khuur strings.

[0042] In this embodiment, the front comb array 4 is located in the area between the upper gathering unit and the lower dispersing plate 53 on the lower cover 2, and is used to perform preliminary combing on the strings led out by the gathering component 3 to break up the initial winding of the strings; the rear comb array 6 is located in the area to the right of the upper and lower dispersing plates 53 on the lower cover 2, and is used to perform fine combing on the strings evenly dispersed by the dispersing component 5; the density of the combing rods 62 on the left half of the rear comb array 6 is lower than that on the right half, which is adapted to the process of the strings from preliminary fine combing to final fine combing. The low-density combing rods 62 on the left half complete the secondary dispersion of the strings, and the high-density combing rods 62 on the right half achieve the precise arrangement of the strings to ensure the combing effect.

[0043] In this embodiment, the lower cover 2 has a stepped positioning groove 61 for installing the combing bar 62. The bottom of the combing bar 62 is fixed with a retainer 63. The diameter of the retainer 63 is larger than the diameter of the combing bar 62. The combing bar 62 is detachably inserted into the stepped positioning groove 61 from bottom to top. Through the cooperation between the retainer 63 and the stepped positioning groove 61, the combing bar 62 is accurately positioned and installed, avoiding the combing bar 62 from shaking or shifting during the combing process. At the same time, the detachable structure makes it convenient to replace the combing bar 62 with different spacing according to the string specifications.

[0044] In this embodiment, a bottom groove 12 is provided at the bottom of the lower cover 2, and the bottom groove 12 is connected to the bottom of the stepped positioning channel 61. A bottom cover 10 is installed inside the bottom groove 12, and the bottom cover 10 is detachably connected to the bottom groove 12 by fastening screws 11. After opening the bottom cover 10, the combing bar 62 can be disassembled and installed from the bottom of the stepped positioning channel 61, which improves the convenience of replacing the combing bar 62.

[0045] In this embodiment, the clustering unit includes a clustering block 32, a clustering slot 33, a clustering cavity 34, and a limiting arm 35. The bottom of the clustering block 32 is engaged in the positioning slot A31. Limiting arms 35 are provided on the front and rear sides of the clustering block 32. The limiting arms 35 have an eight-shaped structure and form a flared inlet end, which facilitates the quick insertion of the strings into the clustering slot 33. A clustering cavity 34 is provided on the upper surface of the clustering block 32. A clustering slot 33 is provided on the left side of the clustering cavity 34 and communicates with it. The clustering slot 33 is connected to the left end face of the clustering block 32. The strings enter the clustering cavity 34 through the clustering slot 33, thereby achieving centralized limiting of the strings.

[0046] In this embodiment, baffle strips 52 are provided on the front and rear sides of the lower dispersion plate 53. The upper end surface of the baffle strips 52 is higher than the top surface of the lower dispersion plate 53 to prevent the strings from slipping off the front and rear sides during the process of spreading along the conical structure of the lower dispersion plate 53. The upper dispersion plate 54 is provided with connecting baffles 56 on the front and rear sides. After the upper dispersion plate 54 and the lower dispersion plate 53 are closed and connected, the connecting baffles 56 and the baffle strips 52 are connected to form a closed anti-slip space, which further improves the stability of the strings during the dispersion process.

[0047] In this embodiment, the hinge assembly 8 includes a hinge seat 81, a hinge joint 82, a torsion spring 83, and a pin 84. The hinge seat 81 is located inside the lower cover 2, and the hinge joint 82 is located inside the upper cover 1. The hinge joint 82 and the hinge seat 81 are rotatably connected by the pin 84 to realize the rotational opening and closing of the upper cover 1 and the lower cover 2. The pin 84 is fitted with a torsion spring 83. One end of the torsion spring 83 abuts against the upper cover 1, and the other end abuts against the lower cover 2. The elastic force of the torsion spring 83 provides a pre-tightening force for opening the upper cover 1, which makes it convenient for the operator to open the device to place the strings. At the same time, when closing the device, the elastic force of the torsion spring 83 can achieve initial clamping.

[0048] In this embodiment, the snap-fit ​​assembly 7 includes an elastic snap-fit ​​plate 71, snap teeth 72, and snap-fit ​​groove 73. The elastic snap-fit ​​plate 71 is made of elastic plastic sheet, which has good elastic deformation and reset capabilities. It is located on the front end face of the upper cover 1, and the snap-fit ​​groove 73 is provided on it. The snap teeth 72 are fixed on the front end face of the lower cover 2. After the upper cover 1 and the lower cover 2 are closed, the snap teeth 72 are engaged in the snap-fit ​​groove 73 to achieve the snap-fit ​​fixation of the upper cover 1 and the lower cover 2. The operator can release the snap teeth 72 from the snap-fit ​​groove 73 by pressing the elastic snap-fit ​​plate 71 to open the device. The operation is convenient.

[0049] Example 2: This example provides a string-changing method using the above-mentioned clustered morin khuur (horsehead fiddle) quick string-changing device, including the following specific steps: Step 1: First, fix one end of the morin khuur string to the designated position on the morin khuur. Open the device through the hinge assembly 8 and place the opened device on the end where the string is fixed. Insert the lower cover 2 from one side of the morin khuur string into the bottom of the morin khuur string and precisely insert the morin khuur string into the clustering slot 33 of the clustering assembly 3, so that the string enters the clustering cavity 34 to achieve initial clustering and limiting. Step 2: The operator uses his hands to spread the strings of the morin khuur from the bundle cavity 34, and then passes the spread strings through the front comb array 4 in sequence to complete the initial combing. Then, the strings that have been initially combed are passed over the lower dispersing plate 53 and introduced to the right side of the rear comb array 6 to prepare for subsequent uniform dispersing and fine combing. Step 3: The operator presses the upper cover 1, causing the upper cover 1 to rotate downward through the hinge assembly 8. At this time, the upper dispersion plate 54 and the lower dispersion plate 53 are precisely engaged. Through the closed engagement of the upper dispersion plate 54 and the lower dispersion plate 53, the strings are evenly spread along the conical structure of the lower dispersion plate 53. At the same time, the evenly spread strings are inserted into the gaps of the combing rods 62 of the rear comb array 6 to achieve string positioning. Step 4: Keep the upper cover 1 and the lower cover 2 closed. According to the string combing needs, use your fingers to control the clamping force of the device on the strings. Then, slowly move the device along the extension direction of the strings to comb the strings and make the strings neatly arranged. Step 5: Repeat the above steps of combing the strings 1-3 times to ensure that the strings are fully combed flat, free from tangles and overlaps, and to ensure the accuracy of the string arrangement; Step 6: During the final string combing operation, move the device to the end of the string and stop there. Keep the device pressed down to shape the string and keep it neatly aligned. Step 7: The operator uses scissors to trim the base of the shaped strings, then uses a lighter to heat and twist the trimmed string base to prevent the strings from unraveling. Finally, the end of the string is fixedly connected to the corresponding position on the morin khuur, completing the string changing operation for the morin khuur.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.

10. A string-changing method using the clustered morin khuur (horsehead fiddle) rapid string-changing device according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: First, fix one end of the morin khuur string to the morin khuur, open the device and place it on the end of the string, insert the lower cover (2) from one side of the morin khuur string into the bottom of the morin khuur string, and insert the morin khuur string into the clustering slot (33) of the clustering assembly (3); Step 2: Spread the strings of the morin khuur and pass them through the front comb array (4). Pass the spread strings over the lower scattering board (53) and introduce them over the right-side rear comb array (6). Step 3: Press the upper cover (1) to close it with the lower cover (2), and the upper distribution plate (54) and the lower distribution plate (53) engage. The closing of the upper distribution plate (54) and the lower distribution plate (53) causes the strings to spread evenly along the lower distribution plate (53), and at the same time, the evenly spread strings are inserted into the back comb array (6). Step 4: Keep the upper cover (1) and lower cover (2) closed, and use your fingers to control the clamping force on the strings. Move the device to comb the strings. Step 5: Repeat steps 1-4 1-3 times to ensure the strings are combed flat and free of tangles; Step 6: When combing the strings for the last time, stop the device at the end of the string and press it down to fix the shape; Step 7: Trim and twist the base of the string, and then fix that end of the string to the morin khuur to complete the string change.
