Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without creative efforts, based on the described embodiments of the present invention belong to the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a structurally optimized suona 900. Suona 900 includes whistle piece 100, air disk 200, core 300, tube 400, and bowl 500. The core 300 and the bowl 500 are respectively connected to both ends of the tube 400. The end of the core 300 away from the pipe body 400 is connected with the whistle piece 100, and the end of the core 300 close to the pipe body 400 is inserted into the pipe body 400. The whistle piece 100, the core 300, the pipe body 400 and the bowl body 500 are sequentially connected together from top to bottom, and the whistle piece 100, the core 300, the pipe body 400 and the bowl body 500 are all of radial through structures, so that when a player blows from the whistle piece 100, the blowing airflow can realize radial flow. The air disk 200 is sleeved on the core 300 at a position close to the whistle piece 100 to concentrate the air flow blown into the whistle piece 100 by a player, so as to achieve the effect of assisting playing. When a player blows the whistle piece 100, the airflow sequentially flows through the core 300, the pipe body 400, and the bowl body 500. Vibrating reed 100 excites the air column in suona 900 to vibrate, which modulate each other at the frequency of vibration to produce sound effects, a process known as coupling. The pitch change is determined by the length of the air column after coupling, and the shorter the air column is, the higher the pitch is.

Referring to fig. 2, eight tube through holes 410 are provided on the tube 400. The eight pipe body through holes 410 specifically include six lower pipe body through holes 411, an upper seventh pipe body through hole 412, and an upper eighth pipe body through hole 413. During playing, a player presses the eight tube through holes 410, and releases the tube through holes 410 from bottom to top in sequence, so that the air column is shortened in sequence, and the pitch is increased in sequence from bottom to top. The player can perform various playing skills such as Shan Tu tones, double vowels, triple vowels, flower tongues, spring tongues, aerosil, strong tones, weak tones and the like on the six lower body through holes 411 under the condition of horizontal blowing and the condition of over blowing.

Referring to fig. 1 and 2 in combination, a core through hole 320 is provided on the core 300. When the player needs to complete the blowing operation of the upper seventh tube through hole 412 or the upper eighth tube through hole 413 in the over-blowing condition, the length of the column of air can be further shortened by putting the core through hole 320 in an open state, thereby accurately completing the over-blowing operation of the two holes. On this basis, the player can smoothly realize various playing skills such as Shan Tu tones, double vowels, triple vowels, flower tongues, spring tongues, aerostats, strong tones, weak tones and the like, which can be completed on the six lower body through holes 411, on the upper seventh body through holes 412 and the upper eighth body through holes 413. In addition, since the through holes 320 are formed in the core 300, the tone and tone of the suona 900 can be maintained during the flat blowing and the super blowing without changing the structure of the tube 400. When the player needs to blow suona 900 in the flat blow condition, the core through hole 320 is closed. When the player needs to perform the over-blowing operation on the six lower body through holes 411, the core through holes 320 are closed.

Referring to fig. 1 and 3 in combination, the cartridge 300 includes a cartridge body 310, a cartridge through-hole 320, a cap hole structure 330, and a seal 340. The core through hole 320 is provided on the core body 310. One end of the cover hole structure 330 is connected to the core body 310, and the other end is movably covered on the core through hole 320. The sealing member 340 is coated on the outside of the core body 310 and is positioned at the junction of the core 300 and the tube 400, so that the core 300 is tightly connected with the tube 400, thereby ensuring the air tightness of the suona horn. In the present embodiment, the sealing member 340 is cork, and in other embodiments, the sealing member 340 may be made of other materials such as rubber.

Referring to FIG. 4 in combination, the core body 310 includes an upper port 311, a lower port 312, a hollow conduit 313, side walls 314, and bosses 315. The side wall 314 is disposed around the hollow pipe 313 so that the core body 310 forms a conical pipe structure with a smaller upper part and a larger lower part and a through center. In this embodiment, the core body 310 is made of copper, and in other embodiments, the core body 310 may be made of other materials. The upper opening 311 of the core body 310 is connected to the whistle piece 100, and the lower opening 312 of the core body 310 is connected to the pipe body 400. The side wall 314 of the core main body 310 is provided with a boss 315, and the core through hole 320 is arranged in the boss 315 and the side wall 314 in a penetrating manner. The outer side of the boss 315 is flat. In other embodiments, the boss 315 may not be disposed on the sidewall 314 of the core body 310, and the core through hole 320 may be directly disposed on the sidewall 314 of the core body 310.

Referring to fig. 5 in combination, the core through hole 320 is provided at a position of the core body 310 near the upper port 311, and in particular, an upper interval L is provided between the center of the core through hole 320 and the upper port 311 of the core body 310, and a ratio between the upper interval L and the total length L of the core body 310 ranges from 18.55 to 25.6%. The center of the core through hole 320 refers to the center point of the core through hole 320 in the radial direction, which is the center of a circle in this embodiment. When the ratio of the upper spacing L to the total length L of the core body 310 is less than 18.55% or greater than 25.62%, a sound break may result. In this embodiment, the upper spacing L between the center of the core through hole 320 and the upper opening 311 is 12.5mm, and the upper and lower offsets in the radial direction are not more than 2mm, i.e., the length of the upper spacing L ranges from 10.5mm to 14.5mm, the total length L of the core main body 310 is 56.6mm, and thus the ratio of the upper spacing L between the center of the core through hole 320 and the upper opening 311 of the core main body 310 to the total length L of the core main body 310 ranges from 18.55 to 25.62%. In other embodiments, the overall length L of the core body 310 may vary with the core size, as may the position of the core through hole 320 above and below the core body 310, but all need to meet this ratio range: the ratio of the upper spacing L between the center of the core through hole 320 and the upper opening 311 of the core body 310 to the total length L of the core body 310 ranges from 18.55 to 25.62%.

In addition, the ratio between the inner diameter D of the core through hole 320 and the outer diameter D of the core main body 310 at the position of the core through hole 320 is less than 22.73%. When the ratio between the inner diameter of the core through hole 320 and the outer diameter of the core body 310 at the position of the core through hole 320 is greater than or equal to 22.73%, the suona 900 leaks too much, which may cause sound breakage. In this embodiment, the inner diameter D of the core through hole 320 is 0.8mm, less than 1.0mm, the outer diameter D of the core main body 310 at the position of the core through hole 320 is 4.4mm, and the ratio between the inner diameter D of the core through hole 320 and the outer diameter D of the core main body 310 at the position of the core through hole 320 is less than 22.73%. In other embodiments, the size of the outer diameter D of the core body 310 may vary, and the size of the inner diameter D of the core through hole 320 may also vary, but the ratio range needs to be satisfied so that the player can accurately perform the playing and avoid the sound breaking.

In the present embodiment, the number of the core through holes 320 is one, and in other embodiments, the number of the core through holes 320 may be two. The two core through holes 320 may be disposed at different positions in the radial direction of the sidewall 314 of the core body 310, or the two core through holes 320 may be disposed at different positions in the lateral direction of the sidewall 314 of the core body 310, but the upper and lower positions of the two core through holes 320 on the core body 310 are required to satisfy the ratio range: the ratio of the upper spacing L formed by the center of the core through hole 320 and the upper opening 311 of the core body 310 to the total length L of the core body 310 is in the range of 18.55-25.62%. In more embodiments, the number of core through holes 320 may be three or more, and the ratio of the upper and lower positions of each core through hole 320 on the core body 310 needs to be within the range: the ratio of the upper spacing L formed by the center of the core through hole 320 and the upper opening 311 of the core body 310 to the total length L of the core body 310 is in the range of 18.55-25.62%.

The return member 335 is an elastic structure for elastically abutting against the core body 310. When the player applies force to the pressing piece 334 to separate the cover 331 from the core through hole 320, the return piece 335 accumulates a return force, and when the player no longer applies force to the pressing piece 334, the return piece 335 releases the return force, thereby resetting the cover 331 to cover the core through hole 320 again. The fixing groove 337 is disposed on the sidewall 314 of the core body 310, and one end of the restoring member 335 is clamped in the fixing groove 337. A stopper 336 is provided on the sidewall 314 of the cartridge body 310 to limit the distance the cover 331 is removed from the cartridge through-hole 320. In the present embodiment, the first end 3361 of the stopper 336 is connected to the sidewall 314, and the second end 3362 is disposed at a predetermined position above the cover 331 to prevent further movement of the cover 331. In other embodiments, the stop member 336 extends from the sidewall 314 toward the pressing member 334, and has one end connected to the sidewall 314 and the other end disposed at a predetermined position near the pressing member 334 to prevent further movement of the pressing member 334, thereby indirectly limiting movement of the cover 331.
