Description

Technical Field

[0001] This utility model belongs to the field of guqin making technology, specifically a guqin body with independent sound-absorbing function. Background Technology

[0002] The guqin, also known as the seven-stringed zither, is a traditional Chinese plucked string instrument. It consists of a soundboard and a backboard, with the soundboard on top and the backboard below, forming a long, box-like structure. The hollow interior forms the sound chamber, which contains sound-absorbing elements. These sound-absorbing elements are used to balance the vibrations of the guqin, reflect sound waves, and refine the tone. Traditional guqins have sound-absorbing elements on the inner surface of the soundboard at corresponding positions on the dragon pool and phoenix pond to balance the vibrations. These are called the dragon pool sound-absorbing elements and the phoenix pond sound-absorbing elements, respectively. Traditionally, these sound-absorbing elements are handmade, and deviations in their shape, size, and surface curvature can lead to uneven vibration transmission, resulting in excessively loud or soft volume, or insufficient purity or evenness of tone. Utility Model Content

[0003] The purpose of this utility model is to provide an independent sound-absorbing guqin body, which replaces the Longchi and Fengzhao sound-absorbing elements in the guqin with a single independent sound-absorbing block. The two ends of the independent sound-absorbing block are fixedly connected to the soundboard and bottom plate of the guqin, and the rest of the independent sound-absorbing block is suspended inside the sound chamber of the guqin body. The overall independent sound-absorbing block can avoid the phenomenon of excessively loud or soft sound caused by local vibration, thereby improving the uniformity of the sound.

[0004] The technical solution of this utility model is as follows: a guqin body with independent soundboard, including a soundboard and a baseboard, and also including an independent soundboard. The independent soundboard is rectangular. Both ends of the inner surface of the soundboard are provided with grooves. The width of the grooves is the same as the width of the independent soundboard. The two ends of the independent soundboard are fixedly connected to the grooves. On the inner surface of the baseboard, protrusions are fixedly connected at positions corresponding to the grooves. The shape and size of the protrusions are adapted to the grooves. The sum of the thickness of the protrusions and the independent soundboard is the same as the thickness of the grooves. The baseboard has a dragon pool and a phoenix pond.

[0005] Furthermore, the two sides of the independent sound-absorbing surface are recessed inward at the waist position of the guqin body.

[0006] Furthermore, the independent sound source is 112.0cm long, 5.0cm wide, and 2.5cm thick, and the gap between the bottom of the independent sound source and the inside of the base plate is 3-5mm.

[0007] Furthermore, the panel and the base plate are bonded together with raw lacquer to form the body of the guqin. The upper sides of the two ends of the independent sound-absorbing device are fixedly connected to the grooves, and the lower sides of the two ends are fixedly connected to the protrusions. The rest of the independent sound-absorbing device does not come into contact with the interior of the guqin body.

[0008] This utility model has the following advantages compared with the prior art:

[0009] 1. This utility model sets up a separate, independent sound-absorbing block in the sound chamber of the guqin, and fixes both ends of the independent sound-absorbing block to the soundboard and the bottom plate of the guqin respectively. The rest of the independent sound-absorbing block is suspended inside the sound chamber of the guqin body. This integrated independent sound-absorbing block can effectively avoid the phenomenon of excessively loud or soft sound caused by local vibration, thereby improving the uniformity of the sound production.

[0010] 2. This utility model improves the structural shape of the sound-absorbing elements in the guqin, creating a fixed-format independent sound-absorbing element. When processing a batch of independent sound-absorbing elements, processing equipment (such as a CNC engraving machine) can be used to mass-produce them. This significantly reduces the processing time for a batch of independent sound-absorbing elements, improves processing accuracy, and reduces the time cost of guqin body production, thus lowering the technical difficulty of guqin body production. This effect is not simply about replacing manual labor with machinery, but rather based on an understanding of traditional guqin making techniques. After improving the sound-absorbing structure, modern technology is used to manufacture and process the independent sound-absorbing elements, so that the final product retains the excellent acoustic characteristics and aesthetic value of the traditional guqin while incorporating the reliability of modern manufacturing.

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

[0019] like Figures 1 to 6 The illustrated guqin body includes a soundboard 1 and a backboard 2. The soundboard 1 and backboard 2 are joined together to form the guqin body. The guqin body is hollow, forming a sound chamber. It also includes independent soundboards 3, which are cuboid in shape. The inner surface of the soundboard 1 has two grooves 4 at both ends. The width of each groove 4 is the same as the width of the independent soundboard 3. The groove 4 at the headstock end is approximately 2cm long, while the groove 4 at the tailstock end is completely opened to the outside. The two ends of the independent sounding 3 are fixedly connected to the groove 4 by wood glue. The inner surface of the base plate 2 is fixedly connected with the corresponding position of the groove 4. There are two protrusions 5. The shape and size of the protrusions 5 and the groove 4 are adapted. The sum of the thickness of the protrusions 5 and the independent sounding 3 is the same as the thickness of the groove 4. When the panel 1, the independent sounding 3 and the base plate 2 of this application are glued together to form the body of the guqin, the independent sounding 3 and the protrusions 5 are embedded and fixed in the groove 4. The base plate 2 has a dragon pool 6 and a phoenix pond 7.

[0020] The waist of the guqin body protrudes inward on both sides to leave space for the foot sockets. To avoid contact with the protruding edges on both sides, the independent sounding element 3 located inside the guqin body needs to be shaped. That is, the two sides of the independent sounding element 3 are recessed inward at the waist of the guqin body.

[0021] In this embodiment, the rectangular independent sounder 3 has a length of 112.0cm, a width of 5.0cm, and a thickness of 2.5cm. The gap between the bottom of the independent sounder 3 and the interior of the base plate 2 is 3-5mm.

[0022] In this embodiment, the panel 1 and the base plate 2 are glued together with raw lacquer to form the body of the guqin. The upper sides of the two ends of the independent sound 3 are fixedly connected to the grooves 4 respectively, and the lower sides of the two ends are fixedly connected to the protrusions 5 respectively. The rest of the independent sound 3 does not contact the inside of the guqin body. After the guqin is assembled, the middle part of the independent sound 3 is suspended in the sound chamber of the guqin body, except that the two ends are fixed.

[0023] It should also be noted that other standard components included in the guqin, such as the bridge, the dew-collecting vessel, the insignia, and the strings, are all common components in the guqin industry. Therefore, the structure of these components and their installation positions on the instrument will not be described in detail in this manual.

[0024] The specific manufacturing steps for the independent sound-absorbing guqin body described in this embodiment are as follows:

[0025] The first step is to select old cedar wood to make panel 1. The outer and inner surfaces of panel 1 are processed according to the drawings, and then grooves 4 of the corresponding size in the drawings are chiseled out at both ends of the inner surface.

[0026] The second step is to manufacture the independent sound source 3. According to the dimensions of the independent sound source 3 in this embodiment, select the same wood as the panel 1, process the independent sound source 3, and process the recesses at the corresponding positions on both sides. Alternatively, a CNC engraving machine can be used to process the independent sound source 3 to improve the processing speed.

[0027] The third step is to select catalpa wood to process and make the base plate 2. Make the base plate 2 corresponding to the panel 1 according to the drawing, and mark the position corresponding to the groove 4. Mark the position where the protrusion 5 is connected. Carve out the corresponding position on the base plate 2 to open the dragon pool 6 and the phoenix pond 7.

[0028] The fourth step is to process the protrusion 5. Select the same wood as the independent sounder 3, process the protrusion 5 according to the size of the groove 4, and glue and fix the protrusion 5 to the marked position on the base plate 2. Alternatively, the processed protrusion 5 can be glued and fixed to the outside of the independent sounder 3 in the corresponding groove 4 to "fill" the groove 4. Finally, when assembling the instrument, glue and fix the outer side of the protrusion 5 to the base plate 2.

[0029] The fifth step is to assemble the instrument. The completed soundboard 1 and backboard 2 are joined together and glued together with raw lacquer to form the body of the guqin. Then, ropes are used to evenly bind the body of the instrument so that the soundboard and backboard can be completely glued together. After that, the ropes are removed, and the body of the guqin is completed.
