Violin with compound strings

Abstract

A violin with compound strings is characterized in that a sound cavity of a violin body is formed by a panel, a back plate and a side plate, and in the sound cavity, an inner horse is pressed by a tightened inner string and the panel is supported so as to resist the panel from sinking due to the pressure of the strings. During string pulling, string vibration of the guitar is transmitted to the inner horse to cause resonance of the inner string, and lingering sound is prolonged. No sound post exists, the amplitude of the panel is not limited, the volume is large, and the timbre is pure.

Description

Technical Field

[0001] The invention belongs to the field of bowed string instruments, and in particular relates to a violin. Background Art

[0002] The existing violin has a sound cavity formed by the top, back and side panels. A bridge is placed between the two sound holes on the top of the body, and a sound post is placed between the top and the back near the bottom of the bridge. The tension of the taut strings, about 25 kilograms, presses on the bridge. The top of the violin drops under the pressure of the bridge, and is supported by the sound post to prevent the top from sinking. When the strings are pulled, the vibration of the strings is transmitted from the bridge to the top, causing resonance. Due to the presence of the sound post, the resonance of the top is limited, which affects the volume, and the asymmetric amplitude affects the timbre. Therefore, there is a need for a violin that can resist the pressure of the strings on the top of the violin without a sound post, and the amplitude of the violin is not limited when the violin resonates. Summary of the invention

[0003] The purpose of the present invention is to provide a violin with compound strings to solve the problem of limited amplitude in the prior art.

[0004] To achieve this purpose, the present invention proposes the following scheme: The present invention provides a violin with compound strings, characterized in that: The appearance of the violin is the same as that of existing violins, with a head, body, sound holes, fingerboard, and bridge, but no sound post. In order to prevent the soundboard from sinking, a bridge is placed in the sound cavity of the body in a mirror image below the bridge. Since this bridge is glued to the bottom of the inner panel of the body, it is called the inner bridge. The sound cavity of the body is equipped with a tightened string called the inner string. The tightened inner string is pressed on the inner bridge and holds up the sound board. The so-called double string means that there is this inner string in the sound cavity of the body, which is a mirror image of the string. When the pegs are tightened, the string and the inner string are tightened at the same time.

[0005] Preferably, the inner string can be an extension of the guitar string, penetrates through the hole of the tail post into the guitar body to press the inner bridge, and then passes through the guitar body and is fixed on the guitar axis of the guitar head.

[0006] Preferably, one end of the inner string is tied to the tail end of the stringboard, passes through the hole of the tail post into the body of the guitar to press the inner horse, and passes through the body of the guitar to be fixed on the peg of the headstock.

[0007] Preferably, the material of the inner string can be steel strings or nylon strings.

[0008] Preferably, the shape of the inner bridge in the sound cavity of the piano body is consistent with the shape of the bridge, and below the bridge, two supporting points are bonded to the inside of the panel, presenting a mirror image arrangement with the bridge.

[0009] Preferably, the inner bridge in the sound cavity of the piano body can also be made with four support points, placed between the front panel and the back panel in the sound cavity, two support points are glued to the inside of the panel below the bridge, and the other two support points are glued to the back panel. The vibration of the strings is transmitted to the back panel to cause resonance and produce sound.

[0010] Preferably, the inner strings offset the pressure of the strings on the panel, and the panel can be made thinner, gradually becoming thinner outwards with the two supporting points of the strings as the center.

[0011] Preferably, the material of the backboard can be maple, which can be formed by hot pressing of a 2-5 mm thin plate. It can also be formed by hollowing out a plate. Because the backboard of the existing violin has to bear the pressure of the strings, it is made thicker. However, this backboard is not subjected to the pressure of the strings, so it can be made thinner and has high resonance sensitivity. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a clear and complete description of the technical solution of the present invention in an embodiment of a violin in the field of bowed string instruments in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field of plucked string instruments or other stringed instrument fields without creative work belong to the protection scope of the present invention.

[0021] The purpose of the present invention is to provide a violin with double strings to solve the problem in the prior art that the resonance of the panel is limited and the volume is affected.

[0022] In order to make the above-mentioned features and beauty of the present invention more obvious and understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations. Example 1

[0023] This embodiment provides a violin with compound strings, including a fractional violin, a violin, a viola, a cello, a bass, and the like. Figure 1-2 shown.

[0024] Like the existing piano, it has a head, body, fingerboard, sound holes, bridge and strings.

[0025] An inner bridge (1) is arranged inside the body of the instrument, and a taut inner string (2) is pressed on the bridge to lift up a panel (3) to prevent the panel (3) from being dented by the pressure of the strings.

[0026] Specifically, the inner string (2) can be formed by extending the string, and one end of the inner string (2) is a loop, which is put on the peg (41). It passes through the perforated neck (4) into the inner cavity of the piano body and is pressed on the inner bridge (1). It passes through the perforated tail post (6). It passes through the tail shoulder (5) and is pressed on the bridge (7). Finally, it is tightly wound on the peg (41) of the headstock. Usually, there are four strings E1, A2, C3, and G4, which are tightly wound on four pegs (41) respectively. Because there is no tailpiece, the tension of the four strings will not affect each other when tuning. The tone is easy to calibrate.

[0027] Specifically, the inner bridge (1) in the inner cavity of the instrument body has the same appearance as the bridge (7), is arranged in a mirror image with the bridge (7), and has two supporting points bonded inside the panel (3). When the string is pulled, the vibration of the string is transmitted to the inner bridge (1), causing the resonance of the inner string (2) to be extended.

[0028] Specifically, the inner string (2) almost offsets the pressure of the string on the panel (3). In order to improve the sensitivity of resonance sound, the panel (3) can be made thinner. The thickness is 3-6 mm and gradually thins outward to 2-4 mm from the two supporting points of the bridge. The bass beam bonded to the panel is not necessary. It can be appropriately thickened according to the density of the panel material. It is also possible to avoid the position of the inner bridge (1) and bond several bass beams.

[0029] Specifically, the backboard of the existing violin is made thicker because it has to bear the pressure of the strings. However, since it is not subjected to the pressure of the strings, it can be made thinner to improve the resonance sensitivity. The material of the backboard can be maple, which can be formed by hot pressing of 2-5 mm thin plates. It can also be formed by hollowing out a 25 mm plate. Example 2

[0030] This embodiment provides a violin with double strings, such as Figure 3-6 shown.

[0031] Like the existing piano, it has a head, body, fingerboard, sound holes, bridge and strings.

[0032] An inner bridge (1) is arranged inside the body of the instrument, and a taut inner string (2) is pressed on the bridge to lift up a panel (3) to prevent the panel (3) from being dented by the pressure of the strings.

[0033] In the above-mentioned embodiment 1, the inner string (2) is formed by extending the strings, and the extended strings need to be ordered.

[0034] Specifically, existing commercial strings can be used, and the inner string (2) can be one or more, which can be determined by a general technician in the field according to actual conditions. In this embodiment, two strings are selected, and one end of the inner string (2) is a loop, which is sleeved on the peg (41). It passes through the perforated neck (4). It is pressed on the inner horse (1). It passes through the perforated tail post (6). It passes through the tail shoulder (5) and is tied to the stringboard (9). When the peg (41) is tightened, the string (10) and the inner string (2) are simultaneously tightened.

[0035] Specifically, the inner bridge (1) in the inner cavity of the instrument body has the same appearance as the bridge (7), is arranged in a mirror image with the bridge (7), and has two supporting points bonded inside the panel (3). When the strings (10) are pulled, the vibration of the strings (10) is transmitted to the inner bridge (1), causing the resonance of the inner strings (2) to be prolonged.

[0036] Specifically, the inner bridge (1) of the inner cavity of the instrument body can also be placed between the panel (3) and the back panel (8), arranged below the bridge (7), and two supporting points (11) are bonded inside the panel (3). The other two supporting points (12) are bonded inside the back panel. When the strings (10) are pulled, the vibration of the strings (10) is transmitted to the inner bridge (1), causing the resonance of the inner strings (2) to be prolonged. At the same time, the inner bridge (1) also causes the back panel (8) to resonate and produce sound.

[0037] Specifically, the backboard (8) of the existing violin is made relatively thick because it has to bear the pressure of the strings. However, since it is not subjected to the pressure of the strings, it can be made thinner, thereby improving the resonance sensitivity. The material of the backboard (8) can be maple, which can be formed by hot pressing a 2-5 mm thin plate. It can also be formed by hollowing out a 25 mm thick plate. The thickness of the backboard is eccentrically distributed, 4-6 mm at the support point (12) of the inner horse (1), and gradually thinning to 2-4 mm outwards. The thickness distribution is as follows: Figure 6 As shown. The bass beam bonded to the back plate (8) is not necessary, and can be appropriately thickened according to the density of the back plate (8) material. It is also possible to avoid the position of the inner horse (1) and bond several bass beams.

[0038] Specifically, the inner string (2) almost offsets the pressure of the string on the panel (3), and the panel (3) can be made thinner to improve the sensitivity of resonance sound. The thickness is 3-6 mm at the center of the two supporting points (11) of the bridge, and gradually thins to 2-4 mm outward. The bass beam bonded to the panel is not necessary and can be appropriately thickened according to the density of the panel material. It is also possible to avoid the position of the inner bridge (1) and bond several bass beams.

[0039] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention; for ordinary technicians in this field, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
