Abstract

The invention discloses a hole covering mechanism for a flute, and belongs to the technical field of flutes. A flute body is provided with a second rear sound outlet hole and a first rear sound outlet hole which are of the same structure at the tail along the axis direction of the flute body, the flute body comprises a four-hole sleeve, a sliding sleeve and an adjusting rotary cylinder, the sliding sleeve is installed in a rabbet at the tail of the flute body, the adjusting rotary cylinder is rotatably sleeved in the sliding sleeve, one end of the sliding sleeve is exposed outside the flute body and is used for manual adjustment, and the other end of the sliding sleeve is used for manual adjustment. The other end of the sliding sleeve penetrates through the sliding sleeve and extends into the flute body, and a four-hole sleeve is installed on the sliding sleeve in the flute body. By rotating the adjusting rotary cylinder, changing the relative position of the four-hole sleeve and the rear sound outlet hole in the flute body and enabling different positions of the outer surface of the adjusting rotary cylinder to be matched with the rear sound outlet hole, the purpose of stepless tone adjustment is achieved, the cost of purchasing and maintaining a plurality of flutes by a player is reduced, the tone of the flute becomes flexible, creation of the player is facilitated, and the flute is worthy of popularization and application. And more possibilities are provided for flute creation.

Description

technical field [0001] The invention belongs to the technical field of flutes, in particular to a hole-shielding mechanism for flutes.

Problems solved by technology

[0003] As far as the existing technology is concerned, the rear sound hole needs to be carefully tuned before the flute leaves the factory. The player will choose a flute with a different rear sound hole structure to play according to the requirements of the repertoire. If there is no suitable flute, it needs to be customized. , which leads to players needing flutes with multiple timbres, and the purchase and maintenance costs of multiple flutes are very high, reflecting the strong correspondence between the existing flute structure and timbre, and poor flexibility, and this kind of flute with almost standardized timbres It is not conducive to the creation of players, and the conditions for trying different timbres are limited
