The air disc 6 is detachably connected to the upper part of the core body 5, which is convenient for replacement and maintenance; the stopper 7 is arranged at the lower part of the core body 5, and is used to limit the position of the core body 5 in the suona rod 3. The core body 5 below the stopper 7 is inserted into the top of the suona rod 3 to ensure the stable connection between the core 2 and the suona rod 3.

[0039] The suona rod 3 includes a suona rod body 16 and an extension tube 17, and the extension tube 17 is detachably connected to the upper end of the suona rod body 16;

[0048] Example 2: B-tuned suona

[0049] Combined with Figure 5 The suona of this tone has the following improvements on its suona rod 3: on the basis of Example 1, an extension tube 17 is added to the upper end of the suona rod body 16, and the outer wall of the upper end of the suona rod body 16 is provided with an external thread 20, the extension tube 17 includes a threaded cap 18 and an extension tube body 19, the lower end of the extension tube body 19 passes through the threaded cap 18 and extends into the suona rod body 16, the inner wall of the threaded cap 18 is connected to the external thread 20 of the suona rod body 16 through an internal thread 21, and the upper end of the external thread 20 is provided with a tension adjustment slot 22; the top end of the threaded cap 18 is provided with a sealing ring 23 which is sleeved on the outside of the extension tube body 19.

[0050] 2. Targeting the bass range.

[0051] Bass music is mainly used in low and melodious mourning songs and operas. It is also used in solo songs in small quantities.

[0052] Most solo performances choose A flat. G major is rarely used because the distance between the sound holes of G major is too large, and it takes a long time of solo practice to accurately control it. However, G major and D major can be played together. Therefore, many people practice the playing habit of the big position alone for the purpose of playing solos. Therefore, the problem of the distance between the sound holes was solved from the bass range. Based on the existing small position, the super small position was designed again.

[0053] Example 3: Suona in B flat

[0054] Combined with Figure 6, the suona of this tone, its suona rod 3 is improved as follows: the distance between the first sound hole 8 and the top of the suona rod body 16 is 47mm, the distance between the second sound hole 9 and the top of the suona rod body 16 is 80mm, the distance between the third sound hole 10 and the top of the suona rod body 16 is 108mm, the distance between the fourth sound hole 11 and the top of the suona rod body 16 is 140mm, the distance between the fifth sound hole 12 and the top of the suona rod body 16 is 172mm, the distance between the sixth sound hole 13 and the top of the suona rod body 16 is 199mm, the distance between the seventh sound hole 14 and the top of the suona rod body 16 is 234mm, the distance between the eighth sound hole 15 and the top of the suona rod body 16 is 234mm, the distance between the eighth sound hole 16 and the top of the suona rod body 16 is 234mm, the distance between the eighth sound hole 15 ... The distance from the top of the suona rod body 16 is 62mm, the length of the suona rod body 16 is 297mm, the inner diameter of the upper end of the suona rod body 16 is 10mm, and the inner diameter of the lower end of the suona rod body 16 is 24mm; a ninth sound hole 24 is also provided on the back of the suona rod body 16, the ninth sound hole 24 is between the first sound hole 8 and the eighth sound hole 15, and the distance between the ninth sound hole 24 and the top of the suona rod body 16 is 54mm; a tenth sound hole 24 is also provided on the front of the suona rod body 16, the tenth sound hole 25 is between the first sound hole 8 and the upper end of the suona rod body 16, and the distance between the tenth sound hole 25 and the top of the suona rod body 16 is 36mm.

[0058] The outer diameter of the upper end of the extended tube body 19 is 12mm, and the outer diameter of the lower end is 9.5mm. An A-adjustment scale mark is provided on the outer wall of the extended tube body 19 20.5mm away from the top. An auxiliary hole is provided at the lower part of the extended tube body 19. The diameter of the auxiliary hole is 7.5mm, and the top of the auxiliary hole is 65mm away from the top of the extended tube body 19. The total length of the extended tube body 19 is 70mm; the inner diameter of the upper end of the threaded cap 18 is 10mm, the inner diameter of the lower end is 15.6mm, and the overall length is 30mm.

[0059] When using a suona of this tone, connect the extension tube 17 to the suona rod body 16, close the ninth tone hole 24 and the tenth tone hole 25, loosen the threaded cap 18 at the same time, push the extension tube body 19 downward to align the A-tone scale mark with the upper end of the threaded cap 18, then tighten the threaded cap 18, insert the reed 1 and the core 2, and install the suona bowl 4 before playing.

[0060] Example 5: Suona in A-flat

[0061] Combined with Figure 6-7 The suona of this tone has the following improvements on its suona rod 3: on the basis of embodiment 4, an A-flat scale mark is provided on the outer wall of the extended tube body 38 mm away from the top,

[0062] When using a suona of this tune, loosen the threaded cap 18 and push the extended tube 19 downward to align the A-flat scale mark with the upper end of the threaded cap 18, then tighten the threaded cap 18, close the ninth tone hole 24 and the tenth tone hole 25, insert the reed 1 and the core 2, and install the suona bowl 4 to play.

[0063] Example 6: Suona in G major

[0066] 3. Targeting the sub-bass range.

[0067] The sub-bass range includes 4 tones. None of them are commonly used. The reasons for not using them are: First, the volume is too large and inconvenient to carry. Normal suona bags and suona boxes cannot fit them. Second, the distance between the 9 sound holes is too large, which is the limit of the finger opening. People with smaller hands cannot play it. Even people with larger hands will feel tired when playing it.

[0068] Take the D-tuned suona for comparison. It is about 100 grams. The weight of the large D-tuned suona is more than 500 grams. It will be very tiring to drag it with one finger for a long time.

[0069] The solution proposed by the invention is to reduce the volume, lighten the weight and reduce the pitch.
