Description

Mouth structure

This creation is related to the technical field of a musical instrument, especially a mouthpiece structure that allows the player to easily express various special effects, and can make the sound quality fuller, thicker, rounder, and clearer.

The general way of playing wind instruments is mainly to blow air into the instrument through the mouth to drive the air in the instrument to vibrate and produce sound. However, because the pipe walls on both sides of the mouthpiece structure of general wind instruments are smooth, so when the air enters the blowing The mouth of the mouth will pass through directly without air resistance and other effects. Therefore, the player needs to work harder to use a variety of more complex blowing techniques in order to show various special effects and flavors. In addition, the sound quality is not full, thick, round and clear enough.

In view of this, the author developed and designed this creation based on the above-mentioned problems, and in-depth ideas, and actively researched and improved trial production.

The main purpose of this creation is to solve the problems of the conventional mouthpiece structure that the player needs to work harder and use a variety of complex blowing skills to show various special effects, and the sound quality of the blown is not full, thick, round and the tone is not clear enough. .

This creative department provides a mouthpiece structure with a through air duct inside, One end of the air duct is formed with a mouthpiece connected to the outside, and the mouthpiece is provided with a connecting portion at the opposite end of the mouthpiece for docking with the main body of the instrument, and the air duct is formed with a slope on the lower side of the mouthpiece. A reflecting surface is provided with two symmetrical concave arc grooves on two opposite side walls, and each concave arc groove is provided with at least one convex rib extending along the groove wall surface and extending to two opposite sides according to the axial direction of the blowing nozzle.

The mouthpiece structure provided by this creation can be designed with two symmetrical sidewalls of the two concave arc grooves and at least one convex rib on the groove wall of each concave arc groove, so that the blown gas can flow through the At the two concave arc grooves, the airflow on both sides can be guided by the ribs, so that the airflow is guided to the center of the gas nozzle along the groove wall surface of the two concave arc grooves, and then the airflow at the center of the blown gas is directed. The concentrated force is squeezed in the middle to create the air resistance effect, so that the player can use the internal air resistance effect to save effort when playing, and can easily show various special effects and flavors without changing It takes a lot of effort to use a variety of more complicated playing techniques, so it is very suitable for beginners. In addition, when the airflow on both sides produces a force that is squeezed and concentrated toward the center of the airflow, the airflow in the center will resist and form a reaction force, so that the airflow on both sides will form a cyclone at the two concave arc grooves. , Thus producing a better resonance effect, which can make the sound quality fuller, thicker and rounder, and the use of the ribs to have regular guidance to concentrate the central airflow can make the sound more clear.

Please refer to Figures 1 to 5, which show that the mouthpiece structure described in this creation has a through air duct 10 inside, and a mouthpiece 20 connected to the outside is formed at one end of the air duct 10, and the mouthpiece A reed (not shown in the figure) can be installed on the 20, and the mouthpiece is provided with a connecting portion 30 at the opposite end of the mouthpiece 20 for docking with the main body of the instrument. The lower side of the air duct 10 at the mouthpiece 20 forms a bevel-like reflecting surface 11, two opposite side walls are provided with two symmetrical and spherical concave arc grooves 12, and each concave arc groove 12 is provided with At least one rib 13 along the wall of the groove and extending in the axial direction of the mouthpiece to two opposite sides. The rib 13 has two inclined surfaces connected at the top, so that its cross-section is generally triangular. In this embodiment, each concave arc groove 12 is provided with a convex rib 13 in the center for dividing the concave arc groove 12 into upper and lower halves.

In this creation, the cross-sectional shape of the rib 13 can also be semicircular... and other shapes.

Please refer to FIG. 6, when the player blows gas into the air duct 10 through the mouthpiece 20, the two symmetrical concave arc grooves 12 and the groove wall of each concave arc groove 12 can be used The structure design of the at least one convex rib 13 on the upper part allows the blown gas to flow through the two concave arc grooves 12. The airflow on both sides can be guided by the convex ribs 13, so that the airflow follows the two concave arc The groove wall surface of the groove 12 is regularly guided to the center of the gas nozzle, and then produces a force that is squeezed and concentrated toward the middle of the airflow at the center of the blown gas, so as to create a better air resistance effect, so that the player can generate internally when playing. The air resistance effect is less labor-saving, and therefore, various special effects and flavors can be easily displayed without the need for more laborious use of various complicated blowing techniques, so it is very suitable for beginners. In addition, when the While the airflow exerts a force that is squeezed and concentrated towards the center of the airflow, the airflow in the center will resist and form a reaction force, and the airflow on both sides will form a cyclone at the two concave arc grooves 12 respectively, thus producing better The resonance effect, in turn, can make the sound quality fuller, thicker and rounder, and the use of the ribs to guide the central airflow can make the sound more clear.
