Description

Technical Field

[0001] The utility model relates to the technical field of konghou, in particular to a hand-operated tuning device for a modern konghou. Background Technique

[0002] The konghou, also known as kanhou or konghou, is a traditional plucked string instrument in ancient China and also a plucked string instrument. The konghou has a history of more than two thousand years. From ancient times to the Tang Dynasty, its playing art has been continuously developed and reached a relatively high level. However, since the late 14th century, the konghou has no longer been popular and has gradually disappeared. Only partial patterns can be seen on the remaining murals and reliefs. The modern Chinese konghou is a new instrument innovated by Chinese musical instrument reformers since the 1970s on the basis of the sketches of the large konghou left in the Qing music score, combined with the characteristics of instruments such as the harp and the guzheng. The new konghou is different from the ancient konghou in terms of appearance, structure and playing techniques, but it still retains the basic characteristics and timbre of the konghou.

[0003] At present, when adjusting the pitch of the existing konghou, it is necessary to manually rotate the adjusting rod. Pressing the string with the adjusting rod will change the tightness of the string. Changing the tightness of the string will change the vibration frequency of the string, and thus change the pitch of the emitted sound. However, since the adjusting rod is small, it is very inconvenient and uncomfortable to use the method of manually rotating the adjusting rod to change the tightness of the string and thus change the pitch of the konghou.

[0004] Therefore, in view of the above problems, it is necessary for the applicant to design a hand-operated tuning device for a modern konghou to solve the problems. Content of the Utility Model

[0013] Furthermore, one end of the fixed rod away from the extension plate movably penetrates through the fixed plate and is threadedly provided with an adjusting screw, and a movable handle is arranged on the outer surface of the adjusting screw.

[0014] Through the above structural design, during use, rotating the movable handle is convenient for driving the adjusting screw to rotate, and the rotation of the adjusting screw is convenient for driving the fixed rod to move along the direction of the stable sleeve.

[0015] Furthermore, a connecting plate is fixedly arranged on one side of the fixed plate, and an adjusting column one is fixedly arranged on one side of the connecting plate.

[0016] Through the above structural design, attaching the string to the adjusting column one is convenient for wire arrangement and convenient for adjusting the string.

[0017] Furthermore, a waist-shaped groove one is formed on the outer surface of several of the adjusting columns, and the waist-shaped groove one abuts against the strings of the konghou.

[0019] Furthermore, a tuning groove is arranged on the outer surface of the tuning column, and the tuning groove is in close contact with the strings of the konghou.

[0020] Through the above structural design, the tuning groove is convenient for preventing the strings of the konghou from falling off, with high safety.

[0021] Furthermore, an adjusting column two for cooperating with the adjusting column one to adjust the string tension is arranged on one side of the movable handle, a waist-shaped groove two is formed on the outer surface of the adjusting column two, and the waist-shaped groove two abuts against the strings of the konghou.

[0022] Through the above structural design, when the movable handle rotates, the adjusting column two will drive the strings of the konghou to move, and cooperating with the adjusting column one will be convenient for adjusting the effective string length of the strings.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows: The manual plucking and tuning device of this modern konghou can conveniently adjust the effective length of the strings on both sides of the konghou, thereby enabling efficient and accurate tuning of the konghou.

At the same time, the rotation of the movable handle will facilitate driving the second adjusting column to press or release the strings on the other side of the konghou. Cooperating with the first adjusting column, it will adjust the effective length of the strings on the other side of the konghou, thereby synchronously changing the effective string lengths of the strings on both sides of the konghou. The change in the effective string length will change the vibration frequency of the strings, and further change the pitch of the emitted sound. The operation is convenient and the use comfort is high. BRIEF DESCRIPTION OF THE DRAWINGS
