Detailed Description

A stringed musical instrument, as shown in fig. 1, fig. 2, fig. 3 and fig. 4, comprises a panel (soundboard) 1, a back board 2 and a side board 3, the side board 3 is bonded around the outer edges of the panel 1 and the back board 2 to form a resonator, the inner side of the panel edge is provided with a sound groove 102, the surfaces of the panel and the back board are respectively arc surfaces which are bulged outwards, the upper end of the resonator in the longitudinal direction is extended upwards to be provided with a headstock 4, the headstock is fixed at the upper end of the resonator through a headstock tenon 401 at the lower end of the headstock, two sides of the upper end of the headstock are provided with tuning pegs 6 for adjusting strings 5, the lower end of the resonator is provided with a tail knob 7, a tail rope 8 of the musical instrument is connected to the tail knob, two ends of the strings are supported and fixed on a string-drawing board arranged on the surface of the panel of the resonator through the tuning pegs and the tail rope, the strings are placed on a bridge, the bridge is erected on the panel for transmitting sound, the grains of the, the structure is a typical structure of string instruments such as violins, and side plates of the string instruments can be integrally spliced and can be randomly spliced with the same wood grain direction. However, the difference between this embodiment and the traditional stringed instrument is that, as shown in fig. 2, the side board is at least divided into four sections, and the wood grain directions of the four sections of the side board are different, that is: the side plates are formed by splicing an upper end side plate 301 and a lower end side plate 302 in the longitudinal direction of the resonator body and two side plates of the resonator body, namely a left side plate 303 and a right side plate 304 in a segmented manner, the wood grains 301-1 of the upper end side plate and the wood grains 302-1 of the lower end side plate are in the transverse up-down direction of the upper end side plate and the lower end side plate, and the wood grains of the upper end side plate and the lower end side plate form a circulation loop with the vertical grains of the wood grains of the panel and the back plate between the; the wood grain directions of the side plates at the two sides of the resonator body, namely the direction of the wood grain 303-1 of the left side plate and the direction of the wood grain 304-1 of the right side plate are mutually vertical to the wood grain directions of the side plates at the upper end and the lower end, and are mutually parallel to the vertical grain directions of the face plate and the back plate. Although the left and right side panels on either side are curved in the middle, the grain direction tends to be up and down, and should be understood to be coincident with the grain direction of the front and back panels, parallel to each other. That is, the wood grain paths of the upper side plate 301 and the lower side plate 302 are not consistent with the wood grains of the left side plate and the right side plate on both sides, and are perpendicular to the wood grains 303-1 and 304-1 of the side plates on both sides. The structure can reduce the mutual action (expansion and contraction) of stress caused by the change of the side plates, the panel and the back plate at the ambient temperature and humidity, and further avoid the cracking of the panel and the back plate due to the stress action.

And, traditional structure curb plate circle is not contract, and the soundboard is the panel can transversely contract and press as time goes on, then curb plate circle is long relatively, and this just needs to cut off a small segment at upper and lower extreme and be fit for the cooperation with the soundboard. This embodiment can avoid the major operation of cutting short the curb plate through the structure after the improvement to the curb plate.

As a further improvement of the structure, it is shown in fig. 3. The cross section of the side plate is of a groove-shaped structure with one open end and the other closed end, the groove-shaped structure comprises an upper side wall plate 305, a lower side wall plate 306 and a vertical wall plate 307 which are bonded together, the edges of the panel and the back plate are bonded to the outer surfaces of the upper side wall plate and the lower side wall plate on the opening side of the groove-shaped structure of the side plate respectively, the closed end of the groove-shaped structure of the side plate protrudes out of the peripheral edges of the panel and the back plate to form a. The protruding edges of the panel and the backboard are at least 2mm, the protruding amount (referring to the high-pitched part instruments) is determined according to different types and sizes of the musical instrument, the upper side wall plate 305 of the groove-shaped structure allows the position of the panel sound groove 102 to be bonded with the edge of the panel, the groove-shaped structure closed end of the side plate protrudes out of the panel and the backboard edge structure to avoid the damage of colliding the panel and the backboard edge, the protruding structure can be used for removing battens embedded in the panel edge sound groove 102 of the traditional stringed instrument, the embedded battens are reduced to be beneficial to the vibration of a resonance box body, labor and materials are saved, and the structure is simple, attractive and adjustable.

The head of the traditional stringed instrument is adhered to the longitudinal upper end face of the resonator body through the head tenon 401 at the lower end of the head, however, the neck and the longitudinal upper end face of the resonator body can be deformed in long-term use, the traditional adhesion can cause difficulty in decomposing the head and the resonator body in repair, the traditional adhesion structure is changed in the embodiment, as shown in fig. 4, the head tenon 401 of the neck is fixed through the screw 9, and the neck is fixed at the longitudinal upper end of the resonator body through the screw 9. Therefore, the headstock and the resonator body are separated only by loosening the screw 9, the use is not influenced, and the angle of the headstock is convenient to adjust.

The violin is called as an improvement on the existing violin, and a sound outlet of a resonance box body is arranged on a vertical wall plate of a groove-shaped structure of a side plate. The sound outlet of the resonance box body can be in various forms, and the position of the sound outlet can be adjusted according to the requirement on the sound, as a preferred scheme: as shown in fig. 1, the sound outlet is arranged on a side plate at one side of the lower part of the resonance box body, as shown in the direction C in fig. 1, and a block 308 is extended outwards from the side plate at the sound outlet; the sound outlet is composed of a plurality of sound windows which are arranged in a row on the side plate.
