TECHNICAL FIELD

[0001] The utility model relates to a plucked musical instrument technical field, especially a musical instrument guqin. BACKGROUND

[0002] Guqin is the abbreviation of Gu Xian, which belongs to the traditional Chinese national plucked musical instrument, and Gu Xian in the Seven Sages of the Bamboo Grove is good at playing this musical instrument and is named after it, and it has a history of more than two thousand years. Guqin has an important position in ancient musical instrument performance, and once became a court musical instrument, and the Guqin inherited to the present is still the main plucked musical instrument in modern folk music. It adopts the twelve equal temperament system, the tone is round and mellow, and the clear overtones can be emitted during performance, so that the attenuation of the sound in transmission is small, and it is suitable for expressing the lyrical and slow melody. In the Wei and Jin Dynasties in China, the literary fashion was popular, and in the literary self-amusement and leisure activities of the literati, Gu Xian became an important way for the Wei and Jin celebrities to value individual emotional experience and express their inner feelings, and gradually formed a unique banquet music culture.

[0003] The modern Guqin is provided with two left-right symmetrical sound holes in the structure, and adopts an external hanging type string binding, the bridge is arranged on the panel of the resonance box, the sound beam is bonded on the inner side of the panel, the sound post is arranged on the sound beam, and the sound post is supported on the upper and lower sides of the resonance box to avoid the deformation of the panel caused by the compression of the bridge. The arrangement of the sound beam limits the free vibration of the panel of the resonance box, affects the conduction of the low-frequency sound in the resonance box, and makes the expression of the tone not thorough enough. At the same time, the strings of the modern Guqin are made of new materials such as synthetic fibers and metal strings, so that the sound is not warm and soft enough, and therefore the modern Guqin cannot clearly and fully express the free and casual personal emotional expression in the literary gathering and banquet. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a musical instrument Guqin, which overcomes the influence of the sound beam in the traditional Guqin on the sound emission and vibration of the resonance box, so that the tone is more round and expressive.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A musical instrument Guqin, which comprises a head, a neck connected below the head, a resonance box connected below the neck, and strings connected between the head and the resonance box, a plurality of frets fixedly connected on the upper surface of the neck and the upper side of the middle part of the panel of the resonance box, a peg provided on the head, a hand cover fixedly connected on the lower side of the middle part of the panel of the resonance box, and the strings being connected between the peg and the hand cover; a slot hole is formed between the hand cover and the panel of the resonance box, an acoustic window is arranged on the panel of the resonance box, and the acoustic window is arranged in the slot hole.

[0007] In the above technical solution, compared with the modern guqin which adopts the mode of externally connecting strings and supporting the strings by the bridge, the strings are connected to the cover hand in the application, and the cover hand is fixed on the panel of the resonance box. In this way, the cover hand only has an upward pulling force on the strings, so that the cover hand cannot press the panel of the resonance box downward to cause the collapse of the panel. Therefore, it is not necessary to install the sound beam with enhanced strength on the inner side of the panel. In this way, the thickness of the panel as a whole is relatively uniform, so that the panel can vibrate more freely, thereby making the sound more smooth, and making the air wave reflection and resonance in the resonance box more uniform, so that the tone is more pure, clear and full, and the inner feelings and charm can be better expressed.

[0008] Preferably, the resonance box further comprises a bottom panel and a surrounding plate, the surrounding plate surrounds the four sides of the bottom panel and the panel to form a flat round resonance box, the first mounting hole and the second mounting hole are oppositely arranged on the surrounding plate, the mounting rod is arranged below the neck, the mounting rod passes through the first mounting hole and the second mounting hole in sequence, and the outer diameter of the mounting rod is in interference fit with the inner diameters of the first mounting hole and the second mounting hole.

[0009] In the above technical solution, the neck is inserted on the surrounding plate through the mounting rod, so that the neck is not connected to the bottom panel and / or the panel of the resonance box, thereby avoiding affecting the uniformity of the bottom panel and / or the panel and avoiding affecting the tone.

[0010] Preferably, the mounting rod is a square rod with thick upper part and thin lower part, and the first mounting hole and the second mounting hole are square holes.

[0011] Preferably, a variable-diameter shoulder is arranged between the neck and the mounting rod, so that the outer diameter of the mounting rod is smaller than the outer diameter of the neck; the bottom end of the neck is in contact with the surrounding plate, and the width of the bottom end of the neck is not greater than the thickness of the surrounding plate.

[0012] Preferably, the cover hand is an arc-shaped block, a groove is formed in the middle of the bottom surface of the cover hand, the bottom surface of the cover hand is fixed on the panel of the resonance box, the groove and the panel of the resonance box form the slot hole, and the sound window is a square.

[0013] Preferably, four through holes are arranged on the upper surface of the cover hand and connected with the strings.

[0014] Preferably, the resonance box is round, the diameter of the resonance box is 36-39 cm, and the thickness of the resonance box is 4.5-5.5 cm.

[0015] Preferably, the strings are silk strings, the head, the neck and the mounting rod are integrally formed, and the plectrum is provided with 12 plectra.

[0016] Preferably, the bottom panel is an arc-shaped plate with a tendency to protrude outward, and the lowest point of the bottom panel corresponds to the sound window.

[0017] Preferably, the upper surface of the neck is flush with the panel of the resonator.

[0018] The beneficial effects of this application are as follows:

[0019] The strings are secured using a hand-over-hand method, preventing the hand from pressing down on the soundboard and causing it to collapse. This eliminates the need for a sound beam inside the soundboard, allowing it to vibrate more freely and enabling smoother sound transmission. The high register is bright yet mellow, while the mid and low registers are full and warm, resulting in a purer, clearer, and fuller tone. This allows for a clear expression of the casual and unrestrained personal emotions conveyed during elegant gatherings and banquets. The neck is attached to the soundboard via a mounting rod, preventing it from connecting directly to the bottom and / or top of the soundboard, which would affect the uniformity of the soundboard and thus the tone. The strings are made of silk, and the overall structure of the soundboard is thinner, resulting in a clearer, mellower, more natural, and rounder tone, enabling the ruan to express the atmosphere of literati banquet music during the Wei and Jin dynasties.
