[0002] When making a guzheng, especially when it comes to the key process of planing the panel, which directly affects the tone, carpenters rely only on feeling and experience. They cannot see or touch it. At most, they can see the remaining thickness around the panel, or use their experience to knock and press the panel to determine whether to continue planing. The existing technology is that the timbre of a guzheng can only be heard after the painting and stringing are completed. The guzheng can only be tuned and graded after the strings are installed in the final process of making the guzheng. However, the timbre quality of the guzheng is already determined during tuning and cannot be changed, resulting in the timbre quality of the guzheng being uncontrollable during the production process.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1-2 As shown, this embodiment provides a guzheng production tester, including a first iron tube 4, a second iron tube 1, an S-beam 5 and a string nail plate 3, the length of the first iron tube 4 is less than the length of the second iron tube 1, one end of the first iron tube 4 is flush with one end of the second iron tube 1, and the two ends of the string nail plate 3 are respectively fixed between the flush ends of the first iron tube 4 and the second iron tube 1; the two ends of the S-beam 5 are respectively fixedly connected to the other ends of the first iron tube 4 and the second iron tube 1, and the outer side surface of the string nail plate 3 is planted with string nails 2 according to the tone zone.

[0033] Specifically, in this embodiment, the length of the first iron pipe 4 is 118 cm, the length of the second iron pipe 1 is 146 cm, the width between the flush ends of the first iron pipe 4 and the second iron pipe 1 is 42.5 cm, and the width between the other ends of the first iron pipe 4 and the second iron pipe 1 is 38.5 cm. The S beam 5 is an S-shaped bolster, and the beam width of the wooden S-shaped bolster is 2 cm, and the thickness of the beam is also 2 cm. The numerical setting in this embodiment is only one possible way to achieve, but the length, width and other values ​​of the sound tester are not limited to this, as long as they can meet the sound test needs.

[0034] In order to enable the string pin plate 3 to be placed on the zither blank 7 and to install the strings, the string pin plate 3 in this embodiment includes a plane layer and a curved surface layer that are made in one piece, the curved surface layer is located on the top of the plane layer, the bottom surface of the plane layer is used to be placed on the zither blank 7, and a yoke is arranged on the top of the curved surface layer. The bottom plane of the plane layer is used to contact the upper surface of the zither blank 7, and the upper part of the curved surface layer is a yoke, which can better fix the strings on the sound tester.

[0035] In this embodiment, in order to test the sound of different sound zones, three to four string pegs 2 are planted on the outer side of the string peg board 3 according to the high, middle and low pitch of the guzheng string, and a tuning handle 6 is added. By arranging the string pegs 2 in the high, middle and low pitch zones, and then fixing the strings, the sound of each tone zone can be tested and tuned, so that the guzheng blank 7 can have better quality.

[0036] In order to be able to match the sound tester with the zither blank 7 for sound testing, the zither production sound tester in this embodiment also includes a workbench 8, the zither blank 7 is placed on the workbench 8, and the position of the string nail plate 3 in the zither blank 7 is aligned with the corresponding prefabricated line on the workbench 8; the sound tester is covered on the zither blank 7, and the Yueshan of the sound tester is aligned with the corresponding prefabricated line on the workbench 8. The four corners of the workbench 8 are respectively provided with screw rods 9, and the sound tester is provided with screw holes corresponding to the screw rods 9, and the screw rods 9 are installed in coordination with the screw holes. In this embodiment, the workbench 8 is 113 cm long, 50 cm wide, and 90 cm high, and the screw rods 9 at the four corners are 15 cm long.

[0037] The steps for testing the sound of the guzheng tester are as follows:

[0038] 1) Thread the string on the sound tester. Drill a hole on the upper part of the S-beam 5 and pass the string in. After the string comes out from the lower part of the S-beam 5, it goes around the outside of the S-beam 5 to the top surface of the S-beam 5 and presses on the S-beam 5. Then stretch the string to one side of the string nail plate 3, press the string on the Yueshan first and then go down around the string nail plate 3 so that the string is passed through the hole of the string nail 2. This method ensures that both ends of the string are pressed on the S-beam 5 and the Yueshan, but its root is stuck on the sound tester, not in the guzheng.

[0039] 2) After repeating step 1) to complete stringing on the tester, place the zither blank 7 with the preliminarily planed panel on the workbench 8. The position of the string nail plate inside the zither blank 7 must be aligned with the prefabricated line of the workbench 8.

[0040] 3) Cover the sound tester on the zither blank 7, and the Yueshan must be aligned with the prefabricated line of the workbench 8 to ensure that the Yueshan in the sound tester is in the same position as the Yueshan of the zither blank 7.

[0041] 4) Connect the screws 9 at the four corners of the workbench 8 to the screw holes of the sound tester and tighten them respectively. At this time, the installation of the sound tester and the zither blank 7 is completed.

[0042] 5) Install the same number of string pegs on the strings according to the string number, and then use the tuning handle to adjust the sound.

[0043] The guzheng production tester of the present invention is a device in which the guzheng strings are reversely mounted on the tester frame and fastened by screws 9 at the four corners of a workbench 8. The strings pressed on the guzheng blank 7 are like strings mounted on the guzheng, and the sound quality of the guzheng blank 7 can be heard, which is conducive to the maker to repeatedly work hard on the planing panel to further improve the sound quality. The reverse stringing method of the tester is combined with the workbench 8, and the guzheng blank 7 is tightly clamped in the middle, so that the guzheng blank 7 is vibrated to produce sound, and the tester can be evacuated at any time after the sound test, which is convenient and efficient.

[0044] The present invention proposes that the sound tester can be used to test the timbre of a guzheng when planing a panel, and the maker is guided to repeatedly process the thickness of the panel according to the test result, which can greatly improve the quality rate of the guzheng's sound quality and solve the problem that the sound cannot be tested at the wood blank stage of guzheng production.
