Description

Technical Field

[0001] The utility model relates to the technical field of konghou, in particular to a tone-changing structure of a modern konghou. Background Technique

[0002] The konghou, also known as kanhou or konghou, is an ancient traditional plucked string instrument in 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. The modern transposing konghou is a new instrument innovated by Chinese musical instrument reformers by combining national musical instruments such as the harp and the guzheng since the 1970s. The new konghou is different from the ancient konghou in appearance, structure and playing techniques, but it still retains the basic characteristics and timbre of the konghou.

[0003] At present, when adjusting the tone of the existing konghou, it is necessary to manually rotate the adjusting screw. Pressing the string with the adjusting screw will change the tightness of the string. Changing the tightness of the string will change the vibration frequency of the string, and then change the tone of the emitted sound. However, due to the smooth surface of the adjusting screw, when the string is loose, the string is easy to fall off, which is inconvenient to use and has a low utilization rate.

[0004] Therefore, in view of the above problems, it is necessary for the applicant to design a tone-changing structure of a modern konghou to solve the problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tone-changing structure of a modern konghou to solve the problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A tone-changing structure of a modern konghou, including a tuning mechanism, which includes a movable plate, an extension plate and a tuning column. The movable plate is installed on the outside of the existing konghou shell so as to be able to move up and down. The extension plate is integrally connected to one side of the movable plate. The tuning column is fixedly installed on one side of the extension plate. When the movable plate is adjusted up and down, the contact force between the tuning column and the string increases or decreases.

[0007] A linkage mechanism, which includes a rotating disk and a waist-shaped rod. The rotating disk is located below the tuning mechanism, and the rotating disk is installed on the outside of the konghou shell so as to be able to rotate and adjust. The waist-shaped rod is fixedly installed on one side of the rotating disk. When the movable plate is rotated and adjusted, the contact force between the waist-shaped rod and the string increases or decreases.

[0008] Further, a stabilizing groove is opened on one side of the movable plate. A positioning screw is arranged inside the stabilizing groove, and one end of the positioning screw is threadedly connected to the konghou shell.

[0009] Through the above structural design, the positioning screw is convenient for restricting the movement track of the movable plate, and has strong controllability.

[0010] Further, a first screw head is fixedly arranged at one end of the positioning screw away from the konghou shell, and the diameter of the first screw head is larger than the width of the stabilizing groove.

[0011] Through the above structural design, when in use, rotating the first screw head facilitates driving the positioning screw to rotate, thereby facilitating the fastening of the connection between the movable plate and the konghou shell.

[0012] Further, a reinforcing screw is arranged inside the stabilizing groove, and one end of the reinforcing screw is in threaded connection with the konghou shell.

[0013] Through the above structural design, the reinforcing screw prevents the movable plate from rotating, facilitating further restricting the moving direction of the movable plate.

[0014] Further, a second screw head is fixedly arranged at one end of the reinforcing screw away from the konghou shell, and the diameter of the second screw head is larger than the width of the stabilizing groove.

[0015] Through the above structural design, when in use, rotating the second screw head facilitates driving the reinforcing screw to rotate, thereby facilitating the fastening of the connection between the movable plate and the konghou shell.

[0016] Further, an adjusting screw is threadedly arranged on one side of the rotating disc, and the adjusting screw is in threaded connection with the konghou shell, and the adjusting screw is in interference fit with the rotating disc.

[0017] Through the above structural design, rotating the adjusting screw facilitates driving the rotating disc to rotate synchronously, and the rotation of the rotating disc will facilitate driving the waist-shaped rod to press the strings, changing the tightness of the strings.

[0018] Further, a sliding groove is formed on the outer surface of the tuning post, and the sliding groove abuts against the strings.

[0019] Through the above structural design, the sliding groove facilitates preventing the strings from detaching from the tuning post.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: The tone-changing structure of this modern konghou can conveniently adjust the tightness of the strings, thereby efficiently and accurately adjusting the tone of the konghou, and can prevent the strings from falling off, with high use comfort. The specific content is as follows:

[0021] 1. A tone adjustment mechanism is provided. When adjusting the tone of the konghou, loosen the first screw head and the second screw head, move the movable plate up and down, and pluck the strings at the same time. When plucking the strings and hearing the target tone, rotate the first screw head and the second screw head, which will drive the positioning screw and the reinforcement screw to rotate, facilitating the fastening of the connection between the movable plate and the konghou housing. After the movable plate reaches the target position, the tuning post will adjust the tightness of the strings, so that the tone of the konghou can be adjusted efficiently and accurately, with convenient use and high comfort.

[0022] 2. A linkage mechanism is provided. When in use, before adjusting the movable plate, rotate the adjusting screw, and the adjusting screw will drive the waist-shaped rod to rotate. The rotation of the waist-shaped rod is convenient for squeezing the strings, thus facilitating the tightening of the strings and preventing the strings from falling off due to excessive looseness, with high comfort in use.
