Description

Technical Field

[0001] The utility model relates to the technical field of violins, in particular to a backhand violin with high loudness. Background Art

[0002] The violin is a string instrument with four strings in total. Sound is produced by the friction between the strings and the bow. Since each person has different habits in using their left and right hands, some practitioners are used to holding the bow in their left hand and the violin in their right hand. This will result in the fingering being opposite to that in the teaching instructions during practice, which can easily lead to learning misunderstandings for practitioners. Therefore, a backhanded violin is designed with the pegs, internal sound beams, sound posts, bridge, strings and chin rest on the backhanded violin in reverse design, which can better suit the different usage habits of practitioners.

[0003] In the prior art, a Chinese patent with authorization announcement number CN215007466U discloses a high-loudness handmade violin, comprising a panel and a back panel, the back panel being located below the panel, a side panel being arranged between the panel and the back panel, a storage mechanism being connected to the outer side of the side panel, a fingerboard being fixedly mounted on the upper surface of the panel near the top position, and a string-bearing plate being fixedly mounted on the upper surface of the panel near the bottom position, a bridge being fixedly mounted on the upper surface of the panel near the middle position, a headstock being connected to the end position of the fingerboard, a string axis being connected to the outer side of the headstock, strings being connected between the string axis and the string-bearing plate, sound holes being opened on the upper surface of the panel near the two sides, a chin rest being fixedly mounted on the bottom of the panel and the side panel near the edge position, and the high-loudness handmade violin described in the utility model can assist in storing the bow of the violin when it is placed, and can provide cushioning support for the cheeks of the user when the violin is used.

[0004] The above mechanism assists in storing the bow of the violin when it is placed, and can provide cushioning support for the cheeks of the user when using the violin. However, in actual use, it is not convenient for the violin to adjust its own sound loudness according to different situations. Insufficient loudness will result in a short sound propagation distance of the violin. Utility Model Content

[0005] The utility model aims to provide a high-loudness backhand violin to solve the problem in the background art that the violin is inconvenient to adjust its own sound loudness according to different situations when in use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-loudness backhand violin, comprising a violin body and a headstock arranged at the upper end of one side of the violin body, a fingerboard is installed on one side of the top of the violin body, and one side of the fingerboard is connected to the headstock, a bridge is installed at the middle position of the top of the violin body, and a tailpiece is installed on the top of the violin body on one side of the bridge, strings are arranged on one side of the top of the tailpiece, and the strings pass through the bridge and extend to the inner side of the headstock, a chin rest is snap-connected on the other side of the top of the violin body, and sound holes are opened at both ends of the top of the violin body;

[0019] 2. In order to prevent the backboard of the violin from being worn due to excessive tightening of the support frame during installation, the cork layer can be used to fill the backboard of the support frame and the violin body to reduce the extrusion wear caused by the support frame. The anti-slip layer can provide a certain degree of protection to the support frame when it is squeezed, thereby effectively reducing the contact between the support frame and the backboard of the violin body. At the same time, the cork layer can be directly disassembled and replaced according to the dirt, ensuring the cleanliness of the backboard of the violin body and reducing the dirt on the violin body.

[0020] Furthermore, when disassembling, the bolt is rotated to separate from the support frame and the support frame is pulled downward, so that the chin rest can be quickly disassembled and replaced. At the same time, it is also convenient to clean the part of the violin body panel that is blocked by the chin rest during daily use. By cleaning the panel and back plate of the violin body in time, the violin body can be better maintained to avoid damage to the violin body due to long-term use. The cushioning pad on the surface of the chin rest can increase the comfort of the cheek when the practitioner is practicing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1:

[0029] like Figure 1 , Figure 5 Figure 6The technical solution shown is to solve the problem that the loudness of the violin is not easy to adjust quickly and accurately when it is in use: the high-loudness backhand violin discloses a loudness adjustment mechanism, including a violin body 1 and a headstock 2 arranged at the upper end of one side of the violin body 1, a fingerboard 4 is installed on one side of the top of the violin body 1, and one side of the fingerboard 4 is connected to the headstock 2, a bridge 6 is installed at the middle position of the top of the violin body 1, and a tailpiece 7 is installed on the top of the violin body 1 on one side of the bridge 6, and strings 3 are arranged on one side of the top of the tailpiece 7, and the strings 3 pass through the bridge 6 and extend to the inner side of the headstock 2, a chin rest 8 is snap-connected to the other side of the top of the violin body 1, sound holes 5 are opened at both ends of the top of the violin body 1, and both ends of the headstock 2 are rotatably connected There is a tuning peg 9, and the tuning peg 9 is staggered at both ends of the head 2. A loudness adjustment mechanism is provided on one side of the tuning peg 9, and the loudness adjustment mechanism is used to limit the rotation angle of the tuning peg 9 to achieve fixation and adjustment of the loudness. The loudness adjustment mechanism includes strings 3, and the strings 3 are respectively wound around the outside of different tuning pegs 9, one side of the tuning peg 9 extends to the inside of the head 2, one end of the head 2 is fixedly connected to a mounting plate 16, and one side of the mounting plate 16 is snap-connected with a block 17, a slot 18 matching the block 17 is provided on the outside of the tuning peg 9, the slots 18 are equiangularly distributed on the outside of the tuning peg 9, and the chin rest 8 is symmetrical about the central axis of the vertical direction of the tuning peg 9, both ends of one side of the block 17 are fixedly connected with a return spring 19, and one side of the return spring 19 is connected to the mounting plate 16.

[0030] In this example, the pegs, internal sound beams, sound posts, bridge strings and chin rest on the violin body 1 are all designed in reverse, so that the practitioner can reduce the practice errors caused by backhand when using the violin body 1 in the backhand. When in use, the violin body 1 mainly adjusts the overall volume by adjusting the tension of the strings 3. The tension of the strings 3 wound around the outside of the peg 9 can be adjusted by rotating the peg 9, thereby achieving the adjustment of the loudness. After the loudness is adjusted appropriately, the position of the card block 17 is adjusted so that the card block 17 can pass through the mounting plate 16 and engage with the appropriate card slot 18, thereby achieving the fixation of the position of the peg 9. Therefore, before the next loudness adjustment is performed, the loudness of the violin is fixed during use, and the tension of the strings 3 will not change due to long-term use, thereby reducing the number of adjustments to the strings 3 during use and increasing the overall applicability during use. Embodiment 2:

[0031] like Figure 1-Figure 4The technical solution shown is to solve the problem that the chin rest 8 is in contact with the violin body 1 for a long time when the violin is in use, causing certain wear on the backboard of the violin body 1: this high-loudness backhand violin discloses a backboard protection mechanism, a cork layer 13 is provided at the bottom end of the violin body 1 above the support frame 11, and the bottom end of the cork layer 13 is fixedly connected to the anti-slip layer 14, and the bottom end of the anti-slip layer 14 is in contact with the outer side of the support frame 11.

[0032] In this example, when installing the chin rest 8, it is necessary to fix the height between the mounting rod 10 and the support frame 11 so that the chin rest 8 can be engaged on the outside of the violin body 1. In order to prevent the support frame 11 from being over-tightened during installation and causing wear on the back panel of the violin body 1, the cork layer 13 can be used to fill the support frame 11 and the back panel of the violin body 1 to reduce the extrusion wear caused by the support frame 11. The anti-slip layer 14 can provide a certain degree of protection to the support frame 11 when it is squeezed, thereby effectively reducing the contact between the support frame 11 and the back panel of the violin body 1. At the same time, the cork layer 13 can also be directly disassembled and replaced according to the dirt, so as to ensure the cleanliness of the back panel of the violin body 1 and reduce the dirt on the violin body 1. Embodiment three:
