Description

Technical Field

[0001] The utility model relates to the technical field of bowed string instrument manufacturing. Background Art

[0002] Bowed string instruments can be roughly divided into two categories: Western bowed string instruments and Chinese folk bowed string instruments. There are two problems to be solved:

[0003] 1. The playing posture of holding the guitar with the head and shoulders is against human nature and affects health.

[0004] Among Western bowed string instruments, the posture for playing violin and viola is the most anti-human. The instrument needs to be clamped between the left shoulder and the chin, and the head needs to be tilted and exerted. In order to keep the instrument level, the left hand needs to support the instrument with the palm facing up, and the right hand needs to raise the palm facing down to move the bow. This posture restricts the free movement of the head, and the head and shoulders remain in a rigid state for a long time, which can easily cause neck muscle strain, shoulder muscle pain, shrugging, fatigue and swelling of the arms and wrists, and even muscle fibrosis, which may cause wrist tenosynovitis.

[0005] As we all know, the posture of holding and playing various types of huqin among Chinese folk instruments is very natural and comfortable. The huqin is tilted on the left leg, the bow hair passes between the two strings, and the bow is naturally placed on the instrument barrel nearly perpendicular to the direction of the python skin. The right hand bow is very relaxed and natural. The left and right hands are raised at the right height and the palms are facing inward, which is very consistent with the natural state of the human body.

[0006] If a violin or other instrument is played directly in the same posture as an huqin, with the bow placed nearly vertically on the left leg, the bow is suspended in the air without support, and the right hand needs to constantly lift the bow without being able to relax. This causes the right hand to become stiff. In addition, the bow has uncertain heights, making it difficult to stably control the bow in the optimal pronunciation position. Therefore, it is difficult for a violin or other instrument to be played directly in the same posture as an huqin, and improvements and innovations need to be made to the structure of the instrument.

[0007] 2. The way the bow hair of the huqin passes between the two strings results in a narrow range of sound and weak high notes.

[0008] Among the Chinese folk bowed string instruments, all types of huqin basically use two strings, with the bow hair between the two strings. This results in a narrow range of huqin, and lacks bass when playing many non-specialized repertoires. In addition, huqins do not have fingerboards, making it difficult to play higher notes, and the treble volume is very weak and distorted. Therefore, performers often need to temporarily lower the tuning of the two strings, which is very troublesome, and they also have to avoid some repertoires that require higher treble.

[0009] In summary, it is necessary to invent a new type of bowed string instrument that has the wide range and strong, bright high notes of a violin, and can be played in a natural and comfortable way of holding the instrument, similar to that of a huqin. Utility Model Content

[0010] To solve the problems of the constraints on people and the impact on health caused by the posture of holding the instrument between the head and shoulders in Western bowed string instruments, as well as the problems such as the narrow pitch range and weak high notes of Chinese huqin, the present utility model provides a new type of bowed string instrument with a bow rest. During performance, the body (1) of the instrument is placed slightly tilted to the left (from the perspective of the performer) on the leg. The bow (2) and the body (1) are independent of each other, the panel of the bow (2) is parallel to the panel of the body (1), and the bow (2) moves left and right on the bow rest assembly (3).

[0011] The technical solution adopted by the present utility model to solve its technical problems is as follows:

[0012] Figure 1 This is a schematic diagram of the present utility model during performance. The present utility model provides a new type of bowed string instrument with a bow rest, including a body (1) and a bow rest assembly (3).

[0013] The bow rest assembly (3) and the body (1) are detachably connected by bolts or buckles, constructing a support platform for the bow (2).

[0014] The body (1) is provided with three or more strings (12).

[0015] The panel (13) of the body (1) is made of wood material.

[0016] The body (1) is provided with a fingerboard (15).

[0017] Figure 2 This is an assembly schematic diagram of the present utility model using bolts for detachable connection. On the curved surface of the side plate (14) of the body (1), there are screw holes (9) for connecting with the bow rest assembly (3). The bow rest assembly (3) is detachably connected to the body (1) through the threaded fit of the handle screw (8) and the screw hole (9).

[0018] Figure 3 This is a composition schematic diagram of the bow rest assembly. The bow rest assembly (3) is composed of an inner shock pad (4), a bow shock support plate (5), a support rod (6), and an outer shock pad (7). The bow shock support plate (5) and the support rod (6) are fixedly connected through pin holes.

[0019] The beneficial effects of the present utility model are as follows:

[0020] 1. Adopting a performance method similar to that of Chinese huqin, the body (1) of the instrument is placed slightly tilted to the left (from the perspective of the performer) on the leg. The method of holding the bow is the same as that of huqin and morin khur. The human head is not restricted, the lifting heights of the left and right hands are appropriate, and the palms are all facing inwards, which is very natural, avoiding the problems of the constraints on people and the impact on health caused by the posture of holding the instrument between the head and shoulders in Western bowed string instruments.

[0021] 2. The body (1) is provided with three or more strings (12), which solves the problem of the narrow range of Chinese Huqin-like instruments.

[0022] 3. The body (1) is provided with a fingerboard (15), and the soundboard (13) of the body (1) is made of wood. When playing, the fingers press the strings on the fingerboard (15), and combined with the fact that the acoustic properties of the wooden soundboard (13) are superior to the python skin materials of most Huqin instruments, the problem of weak high notes of Chinese Huqin instruments is solved.

[0023] 4. The bow bracket assembly (3) and the body (1) are detachably connected by bolts or buckles, constructing a support platform for the bow (2), which solves the problem that the bow (2) loses support in the vertical direction due to the change of the way of holding the instrument. When playing, it is no longer necessary to pick up the bow with the hand, and the skills can be exerted more freely.

[0024] In summary, the present utility model provides a new bow-string instrument with a bow bracket, which not only has a wide range of sounds and strong and bright high notes like a violin, but also can be played in a natural and comfortable way of holding the instrument similar to a Huqin instrument.

[0032]

Embodiment 1

[0033] AsFigure 1 As shown in the figure, a novel bowed string instrument with a bow rest includes a body (1) and a bow rest assembly (3). The bow rest assembly (3) is detachably connected to the body (1) by bolts, constructing a support platform for the bow (2).

[0034] The body (1) is provided with three or more strings (12).

[0035] The panel (13) of the body (1) is made of wood material.

[0036] Figure 2 This is an assembly schematic diagram of the detachable connection implemented by bolts in the present invention. Screw holes (9) for connecting with the bow rest assembly (3) are provided on the curved surface of the side plate (14) of the body (1). The bow rest assembly (3) is detachably connected to the body (1) through the threaded fit of the handle screw (8) and the screw hole (9).

[0037] Figure 3 This is a composition schematic diagram of the bow rest assembly. The bow rest assembly (3) is composed of an inner shock pad (4), a bow shock support plate (5), a support rod (6), and an outer shock pad (7). The bow shock support plate (5) and the support rod (6) are fixedly connected through pin holes.

[0038] Figure 4 This is a side view schematic diagram of the rotatable and adjustable bow rest assembly of the present invention. The distance (F) from the friction surface between the bow rest assembly (3) and the bow (2) to the bridge (16) is preferably 1 / 9 to 1 / 11 of the effective string length (E). It can be adjusted by loosening the handle screw (8), slightly moving the bow rest assembly (3) up and down, and then tightening the handle screw (8). After the performance, the handle screw (8) can be loosened and the bow rest assembly (3) can be rotated to make it close to the body (1), greatly reducing its protruding height and facilitating putting it into the violin case.

[0039] The advantages of this example are: the distance (F) from the friction surface between the bow rest assembly (3) and the bow (2) to the bridge (16) is adjustable. After each performance, it is not necessary to remove the bow rest assembly (3) from the body (1), and only need to loosen and flatten it.

[0040] The disadvantages of this example are: the distance (F) from the friction surface between the bow rest assembly (3) and the bow (2) to the bridge (16) changes slightly after each adjustment based on experience, but the difference is very small and basically does not affect the performance effect.

[0041]

Embodiment 2

[0042] Figure 5This is an assembly schematic diagram of the detachable connection implemented by the buckle of the present utility model. A female buckle (10) for connecting with the bow bracket assembly (3) is provided on the side plate surface of the body (1). A male buckle (11) is provided on the bow bracket assembly (3). The bow bracket assembly (3) is detachably connected to the body (1) through the cooperation of the female buckle (10) and the male buckle (11).

[0043] The advantage of this example is that: after the bow bracket assembly (3) is installed on the body (1) each time, the distance (F) from the friction surface of the bow bracket assembly (3) and the bow (2) to the bridge (16) is fixed. When it is necessary to change the distance (F), just slightly bend the support rod (6) to make it deformed.

[0044] The disadvantage of this example is that: after the bow bracket assembly (3) is pulled out from the body (1), it needs to be placed separately.
