Description

[Detailed explanation of the idea] This invention is an improved version of the mouthpiece of a katabue.

The purpose of this invention is to ensure that the mouthpiece of a hard flute, which is sensitive to outside temperature, such as those made of synthetic resin or metal, is free from the risk of causing so-called "sink" or deformation, and can always generate sound under the same conditions and maintain a stable pitch. The objective is to provide a mouthpiece for a hard flute that can be played.

Therefore, in the present invention, a recess 3 is formed from the shielding surface 2 of the mouthpiece body 1, a vertical piece 4 is placed in the center of the inner half of the recess 3, and a cap-shaped embedded member 5 is provided with the front end open at the front half. The gist of this is the structure of the mouthpiece of a katabue, which is made by fitting together.

In the illustrated embodiment, the entire part is molded from synthetic resin, and the embedded member 5 has a tapered peripheral surface to ensure smooth and secure fitting into the recessed part 3, and the tip abuts against the vertical piece 4. Let them come into contact with you. Further, the embedded member 5 is provided with an oblique surface 5' in order to conform to the plane of the constituent piece 6' of the pore 6 around the recessed portion 3. And mouthpiece body 1
When the connecting end 11 of the outlet pipe 8 is fitted into the connecting circumferential hole 7, the notch 9 of the connecting end 11 enters into the guide protrusion 10 provided on the air hole forming piece 6' to regulate the fitting position. 12 is a blow-in exhalation exhaust window of the blow-out pipe 3;
Edges 13 are formed. 14 indicates a decorative ring of the main pipe 15 and the outlet pipe 8.

As described above, the present invention forms a recess 3 from the shielding surface 2 of the main body, extends the vertical piece 4 in the center of the inner half, and fits the cap-shaped embedded member 5 with the lower surface open in the front half into the recess. Since a space is formed in the entrance part 3, the pores 6 and the recessed part 3 are formed thin and easily warmed by the exhaled air. In the conventional structure, exhaled air condenses on the surface due to the heat insulating effect, creating a liquid film on the inner surface of the pores, but the proposed structure prevents the formation of a liquid film because it warms easily. It is possible to maintain a normal pitch for a long time without the risk of deforming the entire mouthpiece. Further, the vertical piece 4 and the embedded member 5 reinforce the recessed portion 3, thereby having the effect of preventing deterioration of the fastness.
