Description

Technical Field

[0001] The utility model belongs to the technical field of suonas, and specifically relates to a key-added suona that saves effort. Background Art

[0002] The suona is a traditional Chinese double-reed woodwind instrument and a representative national wind instrument in China. The suona has a majestic timbre. The tube body is mostly made of rosewood or sandalwood, conical in shape. At the top, there is a double reed made of reed, which is connected to the wooden tube body through a copper or silver core. At the lower end, there is a copper bowl. The key-added suona also has half-tone keys and high-tone keys, which expand the pitch range and increase the expressiveness of the instrument.

[0003] The suonas on the market now consist of a rod and a suona bowl. There are eight sound holes on the rod. Although the suona has eight holes, the seventh hole sound is the same as the overtone sound of the tube sound, and the eighth hole sound is the same as the overtone sound of the first hole sound, which will accelerate the consumption of effort during overtone playing.

[0004] Therefore, in view of the above problems, a key-added suona that saves effort is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problem that some suonas in the prior art will accelerate the consumption of effort during overtone playing, a key-added suona that saves effort is proposed.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A key-added suona that saves effort according to the utility model includes a suona tube. Eight air holes are equidistantly arranged on the suona tube. A ventilation tube is snap-fitted in the air hole at the uppermost side of the suona tube. A sealing key is arranged on one side of the ventilation tube. A mouthpiece is arranged at the top of the suona tube;

[0007] The sealing key includes a fixed block, a rotating rod, a connecting block, a sealing pad, a resilient steel wire and a dialing block. Two fixed blocks are fixedly connected to the upper side of the suona tube. The two ends of the rotating rod are rotatably connected between the two fixed blocks. The connecting block and the dialing block are fixedly connected to the rotating rod. The sealing pad is fixedly connected to the connecting block. The sealing pad is in fitting connection with the ventilation tube. The resilient steel wire is also fixedly connected between the two fixed blocks. The middle bending position of the resilient steel wire is in fitting connection with the dialing block.

[0008] Preferably, the mouthpiece includes a duckbill mouthpiece, a connecting tube, an annular groove and a rubber ring. The duckbill mouthpiece is fixedly connected to the connecting tube. The connecting tube is in fitting connection with the inner cavity at the top of the suona tube. Two annular grooves are arranged on the connecting tube. The rubber ring is in fitting connection with the annular groove. The rubber ring is in fitting connection with the inner wall of the suona tube.

[0009] Advantages of the Utility Model:

[0010] The utility model provides a keyed suona horn that saves effort. By pressing the dial block, the rotating rod rotates on the fixed block. The rotation of the rotating rod drives the connecting block to rotate, and then drives the sealing gasket to rotate to a position away from the ventilation pipe, opening the ventilation pipe, making it easier and more gas-saving for the suona horn to perform overblowing.

[0011] The utility model provides a keyed suona horn that saves effort. By means of the arranged movable duckbill, the connecting pipe can be inserted into or removed from the suona horn pipe, and the duckbill can be disassembled or installed, which is convenient for cleaning the dirt formed by the water vapor blown out during playing and contaminating the inside of the duckbill.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0021] The following gives specific embodiments.

[0022] Please refer to Figure 1 - Figure 2, the present utility model provides a keyed suona that saves effort, including a suona pipe 1. Eight air holes are equidistantly arranged on the suona pipe 1. A ventilation pipe 2 is snap-fitted in the uppermost air hole of the suona pipe 1. A sealing key 3 is arranged on one side of the ventilation pipe 2. A mouthpiece 4 is arranged at the top of the suona pipe 1;

[0023] The sealing key 3 includes a fixed block 301, a rotating rod 302, a connecting block 303, a sealing gasket 304, a resilient steel wire 305 and a dial block 306. Two fixed blocks 301 are fixedly connected to the upper side of the suona pipe 1. The two ends of a rotating rod 302 are rotatably connected between the two fixed blocks 301. A connecting block 303 and a dial block 306 are fixedly connected to the rotating rod 302. A sealing gasket 304 is fixedly connected to the connecting block 303. The sealing gasket 304 is in close contact with the ventilation pipe 2. A resilient steel wire 305 is also fixedly connected between the two fixed blocks 301. The middle bent position of the resilient steel wire 305 is in close contact with the dial block 306.

[0024] During operation, pressing the dial block 306 drives the rotating rod 302 to rotate on the fixed block 301. The rotation of the rotating rod 302 drives the connecting block 303 to rotate, and then drives the sealing gasket 304 to rotate to a position away from the ventilation pipe 2, opening the ventilation pipe 2, making it easier and more gas-saving for the suona to perform overblowing.

[0025] Further, as Figure 1 - Figure 3 shown, the mouthpiece 4 includes a duckbill 401, a connecting pipe 402, an annular groove 403 and a rubber ring 404. The duckbill 401 is fixedly connected to the connecting pipe 402. The connecting pipe 402 is fitted into the inner cavity at the top of the suona pipe 1. Two annular grooves 403 are opened on the connecting pipe 402. A rubber ring 404 is fitted in the annular groove 403. The rubber ring 404 is in close contact with the inner wall of the suona pipe 1.

[0026] During operation, moving the duckbill 401 can embed the connecting pipe 402 into the suona pipe 1 or remove it from the suona pipe 1 to disassemble or install the duckbill 401.

[0027] Working principle: When using this keyed suona, first assemble this keyed suona. Secondly, when performing overblowing, press the dial block 306 to drive the rotating rod 302 to rotate on the fixed block 301. The rotation of the rotating rod 302 drives the connecting block 303 to rotate, and then drives the sealing gasket 304 to rotate to a position away from the ventilation pipe 2, opening the ventilation pipe 2. Thirdly, when cleaning the duckbill 401, moving the duckbill 401 can embed the connecting pipe 402 into the suona pipe 1 or remove it from the suona pipe 1 to disassemble or install the duckbill 401 for convenient cleaning.

[0028] The basic principles, main features and advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
