Description

Technical Field

[0001] This utility model relates to the field of musical instrument technology, specifically to a double-pillow erhu. Background Technology

[0002] The erhu is a bowed string instrument that is popular among the people. It can play a variety of musical pieces with great flexibility and its sound is melodious and continuous. It can vividly express various emotions such as joy, anger, sorrow and happiness. In particular, the glissando played on it is almost a reproduction of the vocal tone of speech. The erhu is generally made using binding wire as a bridge. Through continuous improvement in recent years, metal movable bridges have been developed. However, the current metal bridges have a shorter range of motion, resulting in less modulation. Summary of the Invention

[0003] To address the problem that the existing metal jacks of erhu have a short range of movement, resulting in limited pitch changes, this invention provides an erhu with a double nut, which can change 12 pitches through the movable jacks.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A double-nut erhu (a two-stringed bowed instrument) includes a soundbox, which includes a skin section located at one end of the soundbox. A neck is fitted onto the skin section. Two symmetrically arranged slots are formed on the upper part of the soundbox, and a jack is provided on each slot. One end of the jack engages with the two slots, allowing the jack to slide within the slots. String holes are provided on the jack. A tone plate is provided between the jack and the neck, with tone marks corresponding to the erhu's pitch. A headstock is connected to the upper end of the neck. A first nut is provided on one side of the connection between the headstock and the neck. A second nut is provided above the first nut, with string holes on the second nut. The second nut is longer than the first nut. By moving the jack up and down within the slots and adjusting according to the tone marks on the tone plate, 12 pitches can be adjusted, allowing for faster and more accurate pitch adjustment during performance, simplifying the adjustment process.

[0006] Furthermore, the headstock has string grooves, and both sides of the headstock are equipped with fixing bolts that extend into the string grooves to secure the strings. The fixing bolts facilitate string adjustment.

[0007] Furthermore, the side of the skin has 24 sound holes. When the soundbox vibrates, mixed tones and echoes are produced through the sound holes.

[0008] Furthermore, the skin of the erhu comprises python skin and a fixing fabric. The python skin is hexagonal in shape, and the cross-sectional size of the python skin is the same as that of the erhu skin portion. This ensures that the python skin covers the erhu skin portion.

[0009] Furthermore, the python skin is pieced together with a fixing fabric, which is positioned around the python skin. This method saves on the use of python skin while ensuring the erhu can produce normal sound, thus reducing the cost of the erhu.

[0010] Furthermore, a support plate is provided below the soundbox to prevent vibration from damaging the soundbox during use.

[0011] The beneficial effects of this utility model through the above technical solution are as follows:

[0012] 1. This utility model allows the use of a shorter first nut by passing the strings through the string holes on the second nut. By replacing the two nuts, the erhu can better imitate different sounds. The first nut can imitate sounds such as the zhuihu, renyu, zhonghu, quhu, leiqin, and matouqin. The second nut can be used like a traditional erhu, and can also imitate sounds such as gaohu, zhonghu, and erquanhu, thus making the erhu more versatile in its imitation capabilities.

[0013] 2. This utility model allows for adjustment of 12 tones by moving the jack up and down within the slot and adjusting according to the tone marks set on the tone plate. This makes the adjustment of the erhu tone faster and more accurate, facilitating tone adjustment during performance and simplifying the adjustment method. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1-3As shown, a double-nut erhu includes a soundbox 1, which includes a skin part 3 located at one end of the soundbox 1. A skin 302 is fitted onto the skin part 3. A neck 4 is connected to the upper surface of the soundbox 1. Two symmetrically arranged slots 5 are opened on the upper part of the neck 4. A jack 7 is provided on the two slots 5. One end of the jack 7 is engaged with the two slots 5 and slides on the slots 5. String holes are opened on the jack 7. A tone plate 6 is provided between the jack 7 and the neck 4. A tone mark 601 is provided on the tone plate 6 corresponding to the tone of the erhu. A headstock 8 is connected to the upper end of the neck 4. A first nut 9 is provided on one side of the connection between the headstock 8 and the neck 4. A second nut 10 is provided above the first nut 9. String holes are opened on the second nut 10. The length of the second nut 10 is longer than that of the first nut 9. A support plate 2 is provided below the soundbox 1. By passing the strings through the string holes on the second nut 10, the short first nut 9 can be used, or the second nut 10 can be used directly. When playing, the jack 7 is plucked, causing the jack 7 to slide in the slot 5, thereby adjusting the pitch. The pitch can be adjusted more accurately according to the pitch mark 601 on the pitch plate 6.

[0020] The headstock 8 has a string groove 11, and there are fixing bolts 12 on both sides of the headstock 8. The fixing bolts 12 extend into the string groove 11 to fix the strings. The strings are fixed and adjusted by fixing bolts 12.

[0021] The skin part 3 has 24 sound holes on its side. When the soundbox 1 vibrates, it produces mixed sounds and echoes at the sound holes.

[0022] The instrument skin 302 comprises python skin and a fixing fabric. The python skin is hexagonal and has the same cross-sectional size as the instrument skin portion 3. The python skin and the fixing fabric are joined together, with the fixing fabric located around the python skin. The fixing fabric can be made of cotton, canvas, damask, silk, or other similar materials.

[0023] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
