[0044] In one embodiment, the cylinder 301 is threadedly connected in the sound hole 2 .

[0045] It can be understood that the cylinder 301 is threadedly connected to the sound hole 2, that is, by twisting the cylinder 301, the length of one end of the cylinder 301 extending into the resonance cavity can be adjusted, thereby facilitating the adjustment of the sound parameters of the Ruan instrument.

[0047] It can be understood that the barrel 301 can be threadedly connected to the internal thread by means of the external thread thereon, so as to achieve threaded connection with the sound hole 2 .

[0048] In one embodiment, an anti-slip layer is disposed on the outer side of the limiting portion 302 .

[0049] It is understandable that the anti-skid layer is provided to avoid slipping when the barrel 301 is twisted, thereby facilitating the adjustment of the sound parameters of the Ruan instrument.

[0050] In one embodiment, the limiting portion 302 is coaxially disposed on the cylinder 301 .

[0051] In one embodiment, lace is provided on the limiting portion 302 .

[0052] It is understandable that lace is provided on the limiting portion 302 so that the limiting portion 302 has both limiting and regulating functions and decorative and aesthetic functions.

[0053] In one embodiment, one end of the sound cylinder 3 is closed, and the other end of the sound cylinder 3 is open, and the open end of the sound cylinder 3 is connected to the resonance layer 1 .

[0054] In one embodiment, the sound cylinder 3 is a wooden sound cylinder or a plastic sound cylinder.

[0055] In one embodiment, two sound holes 2 are symmetrically arranged on the upper side of the resonance layer 1 .

[0056] To demonstrate the effect of the present invention, the following uses the Sonic Visualiser audio analysis software to analyze the audio of the existing Zhongruan and the Zhongruan with a sound tube device, and the audio conditions of the first string, second string, third string and fourth string of the existing Zhongruan are respectively as follows: Figure 4 , Figure 6 , Figure 8 and Fig.10 As shown in the figure, the sound conditions of the first, second, third and fourth strings of the Zhongruan with a sound tube device are as follows: Figure 5 , Figure 7 , Fig. 9 and Fig.11 shown.

[0057] according to Figure 4 The current audio information of the Zhongruan Yixian is shown. Figure 5The sound conditions of the one-string of the Zhongruan with a sound tube device are shown in the one-string comparison table below.

[0058]

[0059]

[0060] It can be seen from the above table that the overtone energy of the octave of the Zhongruan with a sound tube device is stronger, highlighting the thickness and brightness; the changes in the third and fifth degrees of the Zhongruan with a sound tube device are related to the changes in the color of the musical sound. The data shows that the Zhongruan with a sound tube device is between 1700 and 2000Hz, which is not harsh.

[0061] according to Figure 6 The current audio information of the Zhongruan Erxian is shown. Figure 7 The sound conditions of the two-string Zhongruan with a sound tube device are shown in the two-string comparison table below.

[0062]

[0063]

[0064] It can be seen from the above table that the Zhongruan with a sound tube device has a more stable pitch than the existing Zhongruan.

[0065] according to Figure 8 The current sound situation of Zhongruan Sanxian is shown. Fig. 9 The sound conditions of the Zhongruan sanxian with a sound tube device are shown in the following sanxian comparison table.

[0066]

[0067] It can be seen from the above table that the zhongruan with sound tube device has stronger energy in the later period, and the color of the sanxian is slightly stronger.

[0068] according to Fig.10 The current sound conditions of the four-string Zhongruan are shown. Fig.11 The sound conditions of the four-string Zhongruan with sound tube device shown in the figure can be obtained from the four-string comparison table below.

[0069]

[0070] It can be seen from the above table that the thickness and brightness of the existing Zhongruan four-string and the Zhongruan four-string with a sound tube device are basically the same, and the timbre does not change much, but in the cents produced by the later vibration, the energy of the Zhongruan with a sound tube device decays more slowly; in addition, the two are basically equal in the production of cents, but the Zhongruan four-string with a sound tube device has a more stable value in continuous vibration and is slightly brighter.

[0071] In summary, the sound tube 3 can increase the volume of the Zhongruan, making it louder, and can enhance the sound emitted by the instrument and transmit the sound to the surrounding environment; the sound tube 3 can increase the resonance effect of the Zhongruan, so that the instrument interacts with the air or other objects when emitting sound to produce rhythmic and harmonic phenomena, and the sound tube 3 can increase the resonance frequency and intensity of the Zhongruan, thereby making the sound fuller and more resonant; the sound tube 3 can also change the timbre characteristics of the Zhongruan. By designing sound tubes 3 of different shapes, sizes and materials, the frequency distribution and resonance peak of the sound emitted by the Zhongruan can be adjusted, which can make the timbre of the Zhongruan richer and more varied to suit different playing styles and musical styles; in addition, the sound tube 3 can extend the note decay time of the Zhongruan, so that the note lasts longer, which can increase the sustained sound effect of the Zhongruan performance and make the note vibrate longer in the air.
