Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, and particularly relates to a dulcimer capable of improving the high - pitched timbre. Background Art

[0002] The dulcimer is a multi - string musical instrument and is one of the main members of Chinese national musical instruments. Due to the advantages of being easy to learn, low in cost, and having a fresh and pleasant timbre, it has long been loved by the broad masses of the people.

[0003] The existing dulcimer generally includes a body and multiple strings. There are multiple rows of bridges on the soundboard of the body. Each row of bridges is fixedly arranged on the soundboard of the body from left to right in sequence. Both ends of each string are fixedly arranged on the body, and each string is pressed on the corresponding bridge. Each row of bridges divides the strings into a high - pitched area, a middle - pitched area, a sub - middle - pitched area, a low - pitched area, and a low - half - tone area arranged from left to right; due to the different thicknesses of each string and the different lifting positions of the bridges, the strings are usually divided into high - pitched strings, middle - pitched strings, sub - middle - pitched strings, low - pitched strings, and low - half - tone strings. Therefore, the heights of the strings at the same position are all different. However, in the existing dulcimer, due to the need for the arrangement of the high - half - tone positions, the arrangement of the traditional high - half - tone position bridges is the same as that of other bridges on the soundboard, and it is easy to occur the situation that the strings cannot be struck due to too short string spacing or the strings cannot vibrate fully, and the soundboard is pressed and cannot resonate fully, so that the timbre cannot reach the best. Moreover, if the timbre of the high - pitched area is adjusted by changing the position of the bridge on the soundboard, it will also cause too much pressure of the bridge on the soundboard, not only making the timbre dull, but also reducing the service life of the strings. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a dulcimer capable of improving the high - pitched timbre. This dulcimer can not only strengthen the timbre conduction effect of the high - pitched part, making the sound of the high - half - tone clearer and more penetrating, but also make it more convenient for the performer to play and easier to play the pitch required by the piece. The adopted technical scheme is as follows:

[0005] A dulcimer capable of improving the high - pitched timbre includes a body and multiple strings. Roller boards are arranged on both the left and right sides of the soundboard of the body. Bridges are arranged on the roller boards. Headstock boards are arranged on both the left and right sides of the two roller boards. Multiple string pegs are respectively arranged on the two headstock boards. Both ends of each string are respectively connected to two string pegs corresponding in position. Multiple rows of bridges are arranged on the soundboard of the body. Each row of bridges supports each string and divides the strings into a high - pitched area, a middle - pitched area, a sub - middle - pitched area, a low - pitched area, and a low - half - tone area; it is characterized in that: at least one high - pitched position bridge is arranged on the roller board, and the high - pitched position bridge lifts the part of the corresponding string in the high - pitched area.

[0006] As described in this specification, the front and the rear respectively refer to: when a yangqin player is performing, the side of the instrument body closer to the player is the rear, and the side of the instrument body farther from the player is the front.

[0007] By arranging at least one high-pitch string support on the roller board, the above-mentioned yangqin can lift the corresponding parts of the strings in the high-pitch area, effectively changing the angle at which the strings cross with the string supports in the high-pitch range. The size of this angle directly affects the angle at which the player uses the bamboo to strike, avoiding or reducing the situation of hitting other notes or failing to strike. This not only enhances the sound conduction effect of the high-pitch part, making the sound of the high semitone clearer, brighter, and more penetrative, but also makes it more convenient for the player to perform, enabling the player to easily play the pitch required by the piece.

[0008] The above string support arrangement adopts an existing conventional structure, which can refer to the Chinese invention patent specification with the publication number CN102013249A and the patent name "Yangqin String Support".

[0009] As a preferred embodiment of the present utility model, the high-pitch string support is placed on the upper surface of the roller board; the high-pitch string support includes a support block and a metal strip. The metal strip is installed on the top of the support block. The bottom surface of the support block is a plane and is in contact and cooperation with the upper surface of the roller board. The metal strip is in contact and cooperation with the corresponding string. With this structure, the high-pitch string support can be placed as an independent unit on the upper surface of the roller board, and its placement position can be adjusted left and right as needed, as long as the pitch is correct and the sound is bright, making the sound quality better and the performance more convenient.

[0010] As a further preferred embodiment of the present utility model, an inlay groove is provided at the top of the support block; the lower part of the metal strip is embedded in the inlay groove. The material of the support block can be wood or plastic, etc., and the material of the metal strip can be copper or steel, etc.

[0011] The support block can adopt shapes such as a prism shape, a cone shape, or a frustum shape, etc. As a further preferred embodiment of the present utility model, the support block is in the shape of a triangular prism, and the cross-section of the support block gradually becomes larger from its top to its bottom; the inlay groove is opened at the pointed corner part of the top of the support block.

[0012] As a still further preferred embodiment of the present utility model, the support block includes a lower splicing block and an upper splicing block. The lower end of the upper splicing block is spliced with the upper end of the lower splicing block. The material of the lower splicing block is wood, and the material of the upper splicing block is plastic; the inlay groove is opened at the upper end of the upper splicing block. This can enhance the anti-cracking strength of the high-pitch string support and make it not easily damaged.

[0013] As a preferred embodiment of the present utility model, on the upper surface of the rear part of the roller board on the left side, there are multiple groups of high-pitch string bridges arranged in sequence from front to back, and each group of high-pitch string bridges includes at least one of the high-pitch string bridges. Specifically, on the upper surface of the rear part of the roller board on the left side, there are three groups of high-pitch string bridges arranged in sequence from top to bottom. Thus, multiple (such as 3) pitch positions can be added in the high-pitch range, making it easy to play the pitch required by the piece.

[0014] As a further preferred embodiment of the present utility model, the rear part of the roller board on the left side is provided with a widened part; each group of high-pitch string bridges includes two high-pitch string bridges arranged side by side, namely a large string bridge and a small string bridge. The large string bridge is arranged at a position close to the right edge of the widened part, and the small string bridge is arranged at a position close to the left edge of the widened part. "The rear part of the roller board on the left side is provided with a widened part" means that the width dimension of the rear part of the roller board on the left side is larger than that of its front part, which facilitates the arrangement of the large string bridge and the small string bridge on the rear part of the roller board and enables the large string bridge and the small string bridge to have a wider left-right adjustment range.

[0015] As a preferred embodiment of the present utility model, the body of the dulcimer includes a resonance box and a soundboard. A large side board and a small side board are respectively arranged at the front end and the rear end of the resonance box.

[0017] (1) By arranging high-pitch string bridges (at least one) on the roller board, this dulcimer can lift the corresponding parts of the strings in the high-pitch area, effectively changing the angle formed by the intersection of the strings and the string bridges in the high-pitch range. The size of this angle directly affects the angle at which the player uses the bamboo to strike, avoiding or reducing the situation of hitting other notes or not hitting, and strengthening the sound conduction effect of the high-pitch part, making the sound of the high semitone clearer and brighter;

[0018] (2) The high-pitch string bridges can be designed as independent individuals placed on the upper surface of the roller board. Their placement positions are not restricted by the requirements of the pitch positions and can be adjusted left and right as needed. As long as the pitch is correct and the tone is bright, the tone quality is better and the performance is more convenient;

[0019] (3) By increasing the number of high-pitch string bridges, multiple (such as 3) high semitone pitch positions can be added in the high-pitch area, making it easy for the player to play the pitch required by the piece. Description of the Drawings
