[0035] Specific implementation: Refer to Figures 1-6 , the present utility model is a structure for replacing the soundboard skin of a huqin soundbox. Above the soundbox 1 of the huqin, there is a soundpost 7. At least two tuning pegs 8 are installed on the soundpost 7. The tuning pegs 8 are used to fix the upper ends of the strings 9. The strings 9 extend downward along the extending direction of the soundpost 7 from the tuning pegs 8. The structure for replacing the soundboard skin 5 includes:

[0036] A replacement ring 2, which is annular and detachably installed on one side of the soundbox 1 close to the strings 9;

[0037] The soundboard skin 5 is fixed on the replacement ring 2 and closes the ring opening on the side of the replacement ring 2 away from the soundbox 1;

[0038] The replacement ring 2 is arranged between the soundbox 1 and the strings 9, and a bridge 10 is arranged between the soundboard skin 5 and the strings 9.

[0039] For easy understanding, please refer to Figure 3 , and the functions of each structure on the huqin will be described below:

[0040] The soundbox 1: It is the resonance box for the huqin to produce sound, playing the role of amplifying and rendering the vibration of the strings 9. It is mostly made of hard wood such as mahogany, red sandalwood, ebony or wenge, and there are also those made of rosewood, bamboo tubes and other woods. The shapes of the soundbox 1 are mainly regular hexagon, octagon and oval, etc. Different-shaped soundboxes 1 have different sound-producing characteristics.

[0041] The soundboard skin 5: That is, the vibrating membrane, usually a thin and tough python skin with good elasticity, covered on the front end of the soundbox 1. It is an important device for the erhu to produce sound. The thickness and elasticity of the python skin directly affect the timbre and sound quality of the erhu.

[0042] String 9: The erhu has two strings. The inner and outer strings are tuned with a perfect fifth interval. Generally, the inner string is tuned to d1 and the outer string is tuned to a1. The vibration of string 9 is transmitted to the vibrating membrane through the bridge 10. The vibrating membrane then vibrates strongly and strengthens and filters the vibration of string 9, thereby expanding the volume of the erhu and producing wonderful sounds.

[0043] As a preferred embodiment of this embodiment, a plurality of first mounting grooves for mounting the first magnetic blocks 3 are provided on the end surface of the sound box 1 close to the string 9, and a plurality of second mounting grooves for mounting the second magnetic blocks 4 are provided on the end surface of the replacement ring 2 facing away from the bridge 10. Each of the first magnetic blocks 3 and each of the second magnetic blocks 4 are magnetically fixed to each other in correspondence.

[0044] Then, please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , it can be seen that in this embodiment, the end surfaces of the sound box 1 and the replacement ring 2 are both annular surfaces, and a plurality of first magnetic blocks 3 and a plurality of second magnetic blocks 4 are arranged at intervals along the extension path of the annular surface.

[0045] Here, the replacement ring 2 and the sound box 1 are fixed by magnetic attraction, which is convenient for disassembly and assembly, and is convenient for the replacement and maintenance of the replacement ring 2. There is no need to disassemble the whole erhu, nor to worry about damaging parts easily during the disassembly and installation process.

[0046] In addition, in this embodiment, an erhu can be equipped with a plurality of replacement rings 2. Each replacement ring 2 is equipped with a soundboard 5, and the timbres of different replacement rings 2 are different.

[0047] Therefore, for the replacement ring 2 with a damaged soundboard 5, it can be directly replaced with another replacement ring 2 with a sound soundboard 5. The user can replace the soundboard 5 by himself without sending the erhu to a professional repairman.

[0048] Moreover, an erhu can replace the replacement rings 2 with different timbres at any time, thereby enabling the user to play melodies with more different timbres.

[0049] In this embodiment, the cross-sectional profiles of the sound box 1 and the replacement ring 2 are both hexagonal.

[0050] Please refer to Figure 3 , in this embodiment, a string support 6 is fixed below the sound box 1. After the string 9 passes through the bridge 10, its lower end is fixed on the string support 6. The structural design of the bridge 10 and the string support 6 belongs to the prior art and will not be elaborated here.

[0051] Please refer to Figure 2, it can be seen that in this embodiment, the edge of the snake skin 5 extends to the outer side of the replacement ring 2 along its circumferential direction and forms a wrapped edge. A wrapping cloth 11 is also fixedly adhered to the outer side of the replacement ring 2, and the wrapping cloth 11 is arranged outside the wrapped edge.

[0052] Here, the snake skin 5 is fixed on the replacement ring 2 by gluing and closes one side opening of the replacement ring 2. For the convenience of gluing, the edge of the snake skin 5 will be adhered to the outer side of the replacement ring 2 and form a wrapped edge.

[0053] In this embodiment, the wrapping cloth 11 completely covers the outer wall of the replacement ring 2 along its circumferential direction, and the outer contours of the end faces of the fiddle barrel 1 and the replacement ring 2 close to each other are the same. Observed from the outside, there is no obvious boundary at the connection between the replacement ring 2 and the fiddle barrel 1, which is basically the same as the appearance of the wooden fiddle barrel 1 covered with the snake skin 5 in the prior art, and is more acceptable to consumers, and the overall aesthetics is better.

[0054] In this embodiment, the snake skin 5 is python skin or bionic skin.

[0055] Regarding python skin and bionic skin, in terms of materials, python skin is made from the skin of wild snakes, while bionic skin is made from polymer materials. In terms of sound quality, the sound quality of a python skin huqin is traditional and natural, but it has the disadvantages of short lifespan and being easily affected by the environment and humidity. The python skin is prone to sagging in southern cities and cracking in the north, and requires frequent maintenance. In contrast, the sound quality of a bionic skin huqin is more stable, not easily affected by the environment and humidity, and can maintain better sound quality stability. However, although the bionic skin huqin can be comparable to the python skin when used indoors, in outdoor use, the mid-frequency band attenuates more severely.

[0056] Python skin can be selected such as python skin or zaocys dhumnades skin. Among them, when the snake skin 5 is selected as zaocys dhumnades skin, it is particularly susceptible to weather. If directly covering zaocys dhumnades skin on one side of the wooden fiddle barrel 1, during the plum rain season when the weather humidity changes greatly, the wooden fiddle barrel 1 will shrink or expand due to the change in moisture content, which will further cause damage to the zaocys dhumnades skin.

[0057] In this embodiment, the material of the fiddle barrel 1 is wood, and the material of the replacement ring 2 is aluminum. According to requirements, the replacement ring 2 can also be made of other metal materials.

[0058] Since the material of the replacement ring 2 is aluminum, during the process of covering the snake skin 5 on the replacement ring 2, the replacement ring 2 will not be cracked due to being pressed. In addition, due to the high material stability of the replacement ring 2, it can cope with various weather conditions (when the humidity changes, it will not affect the structure of the replacement ring 2), and the snake skin 5 is not likely to appear broken skin phenomenon.

[0059] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
