The thumb rest is located between the violin body and the hand rest assembly, while the shoulder pad bracket is installed at the bottom of the violin body via a metal connecting rod, and a detachable shoulder pad is mounted on the shoulder pad bracket. The beneficial effects of this utility model are: the thumb rest provides support for the player's thumb, especially during high-position playing, eliminating the need for continuous hand muscle exertion to maintain hand posture for pressing the strings, thus avoiding fatigue caused by prolonged "unnatural tension" of the muscles. Furthermore, the player can adjust the shoulder pad to a suitable position according to their own needs, adjusting the contact shape of the shoulder pad based on the shoulder curve of different players, thereby maximizing the contact area between the shoulder pad and the shoulder and distributing pressure, ensuring the stability of the violin body during playing and preventing localized shoulder discomfort.

Description

Technical Field

[0001] This utility model relates to an electroacoustic violin, and more particularly to a one-piece molded multi-string electroacoustic violin with frets. Background Technology

[0002] Violin instruments are generally divided into violins, violas, cellos, and double basses, and most violin instruments have a four-string structure. Traditional violins are limited by the fretless fingerboard, making intonation control difficult and lacking electroacoustic output capabilities; however, when performers need to play more notes, the number of strings on the violin is increased to meet the required scale, thus giving rise to five-string, six-string, and seven-string violins.

[0003] Conventional violins are equipped with a soundbox for resonance. When played, the sound is emitted from the sound hole after resonance. The structure of this type of violin is relatively simple, but the sound is not easy to control during use, which can be annoying when practicing. In addition, the output sound is difficult to pick up and process for secondary output.

[0004] Based on the above shortcomings, the inventors conducted long-term research and developed a new type of electro-acoustic silent violin (CN220984156U). However, during use, it was found that the violin lacks a thumb support structure. When playing in the high positions, the hand is in a suspended state, and the hand muscles need to exert continuous force to maintain the hand posture in order to complete the string pressing action. This causes the muscles to be in an "unnatural tension state" for a long time, resulting in fatigue. Moreover, the curvature and size of the fixed chin rest structure are fixed, and it is impossible to adjust the contact shape according to the different shoulder curves (shoulder width, collarbone curvature differences) of different players. This results in a small contact area between the chin rest and the shoulder and concentrated pressure, which not only affects the stability of the violin body during playing, but also easily causes local pressure discomfort in the shoulder. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a one-piece molded multi-string electroacoustic violin with frets.

[0006] The purpose of this utility model is achieved through the following technical solution: an integrated multi-string electro-acoustic violin with frets, including a violin body, a detachable hand rest assembly installed on the violin body, a thumb rest and a shoulder pad bracket installed on the violin body, the thumb rest being located between the violin body and the hand rest assembly, and the shoulder pad bracket being installed at the bottom of the violin body via a metal connecting rod, and a detachable shoulder pad being installed on the shoulder pad bracket.

[0007] Optionally, the hand rest assembly is detachably connected to the body of the instrument via a locking screw. The thumb rest has a hole through which the locking screw passes. When the locking screw is tightened, the thumb rest is pressed together by the body of the instrument and the hand rest assembly.

[0008] Optionally, the shoulder pad support includes a frame extending to both sides, with the middle of the frame detachably connected to a metal connecting rod, and wing plates for connecting the shoulder pads provided at both ends of the frame.

[0009] Optionally, the mounting surface of the shoulder pad has screw holes, and the wing plate has through holes. The shoulder pad and the wing plate are locked together by locking screws that pass through the through holes and are locked to the screw holes.

[0010] Optionally, the shoulder pad and the wing plate are connected by a clamping bracket, which includes a connecting plate. The outer side of the connecting plate has multiple inwardly folding elastic claws that clamp the corresponding wing plate. A connecting screw is installed at the bottom of the connecting plate and is threadedly connected to the shoulder pad.

[0011] Optionally, the tail of the instrument body is provided with a mounting hole, one end of the metal connecting rod is inserted into the mounting hole, and the tail of the metal connecting rod is also provided with a connecting bracket extending outward, and a pin is provided radially outward on the connecting bracket, the pin being inserted into the mounting hole of the chin rest.

[0012] Optionally, a stepped post is provided radially inward at the tail of the metal connecting rod, and a through hole is provided in the middle of the frame. The small post of the stepped post is installed in the through hole, and a locking screw hole is provided on the end face of the stepped post.

[0014] Optionally, the frets are integrally formed on the body of the instrument, and the frets are elongated raised structures.

[0015] This invention has the following advantages: The multi-string electroacoustic violin of this invention uses a thumb rest, which supports the player's thumb. When playing in higher positions, the hand is supported by the thumb rest, and the hand muscles do not need to exert continuous force to maintain the hand posture to complete the string pressing action. This avoids fatigue caused by the muscles being in an "unnatural tension state" for a long time. Moreover, the player can adjust the shoulder pad to a suitable position according to their own situation, that is, adjust the contact shape of the shoulder pad according to the shoulder curve of different players, so that the contact area between the shoulder pad and the shoulder is large and the pressure is distributed, thereby ensuring the stability of the violin during performance and avoiding local pressure discomfort in the shoulder.

[0023] like Figure 1 As shown, a one-piece molded multi-string electro-acoustic violin with frets, adapted to multi-string (5-7 string) violins, includes a body 1, which is integrally injection molded. When the body 1 is integrally molded, its first fret is integrally formed on the fingerboard of the body 1. The fret is a long, raised structure. A detachable hand rest assembly 2 is installed on the body 1. A thumb rest 3 and a shoulder pad bracket 4 are also installed on the body 1. The thumb rest 3 is located between the body 1 and the hand rest assembly 2. The shoulder pad bracket 4 is installed at the bottom of the body 1 via a metal connecting rod 5, and a detachable shoulder pad 6 is installed on the shoulder pad bracket 4. In this embodiment, as... Figure 3As shown, the hand rest assembly 2 is detachably connected to the instrument body 1 via a locking screw. The thumb rest 3 has a hole through which the locking screw passes. When the locking screw is tightened, the thumb rest 3 is pressed together by the instrument body 1 and the hand rest assembly 2. In this embodiment, the back of the instrument body 1 has a mounting surface 15 with screw holes matching the locking screw. The thumb rest 3 has a surface that fits against the mounting surface 15. Preferably, when the thumb rest 3 is installed, the contact surface of the thumb rest 3 fits against the corresponding back of the instrument body 1. Through the thumb rest 3, the player's thumb can pass through the thumb rest. The thumb rest 3 provides support, and when playing in high positions, the hand is supported by the thumb rest 3. The hand muscles do not need to exert continuous force to maintain the hand posture to complete the string pressing action, thereby avoiding fatigue caused by the muscles being in an "unnatural tension state" for a long time. In this embodiment, the shoulder pad 6 is a commercially available product. The middle part of the shoulder pad 6 has a thin-walled structure, and both ends of the shoulder pad 6 have protrusions 16, which are detachably connected to the shoulder pad 6. When selecting the shoulder pad 6, an ergonomic shoulder pad 6 can be selected to avoid concentrated shoulder pressure, thereby ensuring the stability of the instrument body 1 during playing.

[0024] In this embodiment, as Figure 2 As shown, the shoulder pad support 4 includes a frame 7 extending to both sides. The middle of the frame 7 is detachably connected to a metal connecting rod 5. Wing plates 8 for connecting the shoulder pad 6 are provided at both ends of the frame 7. Further, as... Figure 4 As shown, the mounting surface of the shoulder pad 6 has screw holes, and the wing plate 8 has through holes 13. The shoulder pad 6 and the wing plate 8 are locked together by locking screws that pass through the through holes 13 and are locked with the screw holes. That is, screw holes are provided on the boss 16, and then the shoulder pad 6 is locked with locking screws to complete the installation. Preferably, there are multiple screw holes on the boss 16 and multiple through holes 13 on the wing plate 8. The player can adjust the shoulder pad 6 to a suitable position according to their own situation, that is, adjust the contact shape of the shoulder pad 6 according to the different shoulder curves (shoulder width, collarbone curvature differences) of different players, so that the contact area between the shoulder pad 6 and the shoulder is large and the pressure is distributed, thereby ensuring the stability of the instrument body 1 during performance and avoiding local pressure discomfort in the shoulder.

[0025] In another embodiment, such as Figure 5As shown, the shoulder pad 6 and the wing plate 8 are connected by a clamping bracket. The clamping bracket includes a connecting plate 17.
