Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, in particular to a zither bridge which improves the sound quality and prevents lateral deviation to stabilize the pitch. Background Art

[0002] The structure of the zither horse in the prior art is as follows: Figure 5-6 As shown, it includes a zither bridge body, a string-resting groove is provided in the middle of the zither bridge body, and the strings are supported in the string-resting groove. When the left hand presses the strings, due to the action of force and the large friction between the strings and the top of the zither bridge, the zither bridge's string-contacting point will be offset to the right with the force (the strings are pulled to the left, and the zither bridge remains in the original position), so that after the force is removed, the string-contacting point still stays at the offset position, resulting in a high basic pitch, which will wear out the strings over time;

[0003] On the other hand, in severe cases, it may even cause the horse's foot to slightly deviate to the left side, resulting in the horse's foot not being able to fit tightly with the soundboard, and when the strings are loosened, the horse's foot is reset to form a collision with the soundboard, and the displacement of the horse's foot of the zither bridge and the frequent collision between the soundboard reduce the service life of the guzheng, increase the noise of playing, and also affect the conduction of the sound, resulting in poor timbre; similarly, applying force on the right side will also cause the same problem. In addition, the determining factor of the brightness of the guzheng's timbre lies in the size of the contact surface between the strings and the bridge. The larger the contact surface, the darker and more muffled the sound; the smaller the contact surface, the clearer the sound. In the prior art, the contact area between the strings and the bridge is large, so that the brightness of the timbre and the sound quality cannot achieve a good effect. Utility Model Content

[0004] The utility model aims to provide a zither bridge which can improve the sound quality and prevent lateral deviation to stabilize the pitch, and can effectively solve the problems in the background technology.

[0005] The technical solution to achieve the above-mentioned purpose is: a zither bridge for improving sound quality and preventing lateral deviation to stabilize pitch, including a zither bridge body for supporting strings, a string-touching block is arranged on the top of the zither bridge body, and is characterized in that the string-touching block is in a mountain-shaped structure along the direction of string arrangement, forming a first string-touching protrusion located in the middle and second string-touching protrusions located on both sides, and the height of the first string-touching protrusion is higher than the second string-touching protrusions on both sides.

[0006] Furthermore, a string-receiving groove is provided in the middle of the first string-touching protrusion, and the heights of the second string-touching protrusions on both sides are lower than the bottom height of the string-receiving groove.

[0007] Furthermore, when no additional pressure is applied, the strings supported on the zither bridge are in contact with the first string-touching protrusion and separated from the second string-touching protrusion. When pressure is applied, the strings are in contact with the first string-touching protrusion and at the same time in contact with the second string-touching protrusion on the pressing side.

[0008] The beneficial effects of the utility model are as follows: when pressure is applied to the strings on one side of the zither bridge body, the strings are in contact with the first string-touching protrusion and the second string-touching protrusion on the pressing side at the same time, forming double contact points, making the zither bridge body supporting structure more stable, and the force of the strings on the zither bridge is divided into a horizontal force component and a downward force component, and the double contact points can reduce the horizontal force on the pressing side, thereby reducing or even avoiding the zither bridge from deviating toward the string pressing side; at the same time, the double contact points reduce the displacement of the zither bridge foot and the frequent collisions between the soundboard, thereby increasing the service life of the zither and improving the timbre stability of the zither.

[0009] The utility model designs the string-touching block of the zither bridge body into a "mountain"-shaped structure, and sets the thickness to be the same as the thickness of the existing zither bridge body, forming a middle peak and auxiliary side peaks on both sides, thereby reducing the actual contact area between the strings and the "mountain"-shaped zither bridge (the "middle peak"), significantly improving the stability and timbre brightness of the sound, and greatly enhancing the sound quality.

[0010] When playing the guzheng, it is necessary to press the strings. With the existence of the "auxiliary side peak", after applying pressure on the strings perpendicular to the guzheng panel, the strings can be pressed down and contact the "auxiliary side peak", thereby obtaining an upward supporting force provided by the "auxiliary side peak", so that the main body of the guzheng bridge remains stable and does not deviate, thereby maintaining the original pitch after the action of pressing the strings is completed.

[0011] The "mountain"-shaped zither bridge has a middle peak and auxiliary side peaks symmetrically arranged on both sides, so that the bridge can be used in both directions. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1-2As shown, the utility model discloses a zither bridge body 1 for supporting strings, a string-touching block 2 is arranged at the top of the zither bridge body 1, the string-touching block 2 is in a mountain-shaped structure along the arrangement direction of the strings, forming a first string-touching protrusion 2.1 located in the middle and second string-touching protrusions 2.2 located on both sides, a string-resting groove 2.11 is arranged in the middle of the first string-touching protrusion 2.1, and the height of the second string-touching protrusions 2.2 on both sides is lower than the groove bottom height of the string-resting groove 2.11.

[0019] like Figure 3-4 As shown, when in use, the string 3 is supported in the string resting groove 2.11. When no additional pressure is applied, the string 3 supported on the zither bridge body 1 is in contact with the first string-touching protrusion 2.1 and is separated from the second string-touching protrusions 2.2 on both sides. When pressure is applied, the string 3 is in contact with the first string-touching protrusion 2.1 and the second string-touching protrusion 2.2 on the pressing side at the same time.

[0020] For example, when the left side string 3 of the zither bridge body 1 is pressed, the string is simultaneously in contact with the first string-touching protrusion 2.1 and the second string-touching protrusion 2.2 on the left side, forming a double contact point, making the supporting structure of the zither bridge body 1 more stable. The force F1 exerted by the left side string 3 on the zither bridge body 1 is divided into a horizontal component F2 to the left and a vertical component F3 downward. The double contact point reduces the horizontal component F2 on the left side, thereby reducing or even avoiding the lateral deviation of the zither bridge body 1 when pressing against the string 3; at the same time, it reduces the displacement of the foot of the zither bridge body 1 and the frequent collisions with the soundboard, thereby increasing the service life of the zither and improving the timbre stability of the zither.

[0021] The utility model designs the string-touching block of the zither bridge body 1 into a "mountain"-shaped structure, forming a middle peak and auxiliary side peaks on both sides, thereby reducing the actual contact area between the strings and the "mountain"-shaped zither bridge ("middle peak"), significantly improving the stability and timbre brightness of the sound, and greatly enhancing the sound quality.

[0022] When playing the guzheng, it is necessary to press the strings 3. With the existence of the "auxiliary side peak", after applying pressure on the strings perpendicular to the guzheng panel, the strings 3 can be pressed down and contact the "auxiliary side peak", thereby obtaining an upward supporting force provided by the "auxiliary side peak", so that the guzheng bridge body 1 remains stable and does not deviate, so that the original pitch is maintained after the string pressing action is completed.
