Description

Technical Field

[0001] The invention belongs to the technical field of musical instrument manufacturing auxiliary tools, and in particular relates to a sound quality detection device used in the manufacture and maintenance of guzheng. Background Art

[0002] The guzheng is an ancient Chinese folk instrument, popular in the Qin Kingdom (present-day Shaanxi Province) 2,300 years ago, hence the name Qinzheng. The guzheng consists of a soundboard, pegs, strings, nut, S-shaped nut, string pegs, case, legs, side panels, sound holes, bottom panel, and string holes. It is a rectangular wooden sound box with nut at each end of the soundboard. Strings are strung over the nut, threaded through eyelets in the string holes, and secured to the pegs. Turning the pegs adjusts string tension, and thus pitch. The bridge directly below the strings is free to move, transmitting vibrations from the strings to each note, arranged according to the pentatonic scale. Different guzheng varieties have different constructions. The quality of a guzheng depends primarily on the material quality and structural design of its components.

[0003] The guzheng produced in many places now adopts the frame masking production process. The resonance box of the frame masking guzheng is composed of a panel, a bottom plate and a frame. The production process of this process is to first make the guzheng frame. The frame is composed of high and low bass side panels, a guzheng head cover plate, a guzheng tail cover plate, a peg plate, a sound beam and a bottom plate. The function of the sound beam is to support the panel, prevent the panel from collapsing, and increase the strength of the frame; the panel and the bottom plate are cut according to the technical requirements, and the frame, panel and bottom plate are prepared for assembly after they are made. First, the panel is humidified and heated to be bent into shape, and then the panel and the bottom plate are glued and fixed to the frame. The disadvantage of this process is that the panel bends and deforms under the action of external force, and there is internal stress. At the same time, the panel is in close contact with the sound beam, and the sound beam will hinder the vibration of the sound board. The panel cannot vibrate completely freely, the bass is not thick enough, and the sound is thin and not full. The existing digging and struggling manufacturing process, depending on the different materials, the different thicknesses during production, or the uneven thickness of the materials, leads to poor timbre of the guzheng produced. Summary of the Invention

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a sound quality detection device for use in the manufacture and maintenance of guzheng, which can detect the timbre effect of the resonance cavity during the manufacture or maintenance of guzheng so as to make timely adjustments or repairs.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A sound quality detection device used in the manufacture and maintenance of a guzheng comprises a cover (1) and a base (2), characterized in that the cover (1) and the base (2) are connected by a hinge (3) and fastened by a lock (4); the bottom plate of the base (2) is provided with two sound holes (10); a front yueshan (6) is fixed to one end of the cover (1), and a string pressure rod (9) is fixed to the cover (1) on one side of the front yueshan (6); a rear yueshan (5) is fixed to the other end of the cover (1); a string button (7) is provided on the top of the cover (1) at the front end of the front yueshan (6), and a string hook (8) is provided on the cover (1) at the rear end of the rear yueshan (5).

[0007] Support strips (11) are provided on both sides of the base (2).

[0008] The front Yueshan (6) and the rear Yueshan (5) are covered with strings, one end of the strings is connected to the string hook (8), and the other end is connected to the string button (7).

[0009] The strings are supported by bridges.

[0010] The beneficial effects of the present invention are:

[0011] The device can be used for sound testing after the panel is manufactured, instead of after the resonance box is completely manufactured. Alternatively, when repairing a guitar, the original strings do not need to be installed, and the device can be used for repair directly. The operation is convenient, and the production efficiency and sound quality are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 、 2As shown in Figures 3, 4, and 5, a sound quality detection device used in the manufacture and maintenance of a guzheng comprises a cover (1) and a base (2), characterized in that the cover (1) and the base (2) are connected by a hinge (3) and fastened by a lock (4); the bottom plate of the base (2) is provided with two sound holes (10); a front mountain (6) is fixed to one end of the cover (1), and a string pressure rod (9) is fixed to the cover (1) on one side of the front mountain (6); a rear mountain (5) is fixed to the other end of the cover (1); a string button (7) is provided on the top of the cover (1) at the front end of the front mountain (6), and a string hook (8) is provided on the cover (1) at the rear end of the rear mountain (5).

[0020] Support strips (11) are provided on both sides of the base (2).

[0021] The front Yueshan (6) and the rear Yueshan (5) are covered with strings, one end of the strings is connected to the string hook (8), and the other end is connected to the string button (7).

[0022] The strings are supported by bridges.

[0023] The working principle of the present invention is:

[0024] Place the guzheng resonance box that has not yet been sealed with the bottom plate in the base, cover it with the lid, and lock it with the lock. The guzheng resonance box with the bottom plate and the base form a resonance box. The base is equivalent to the bottom plate and has sound holes. Then install the strings with the lid. One end of the string is connected to the string hook and the other end is connected to the string knob. It can be supported by the bridge or the bridge can be left out. The string can be pressed by the string pressure rod, and then the string knob is adjusted to tune the sound. After playing, feel the tone of the resonance box. If the tone does not sound right, take out the guzheng resonance box without the bottom plate, reprocess it, and then put it back in for sound quality testing.
