Description

Saxophone flute head

Technical Field

The utility model belongs to the technical field of musical instruments. In particular to a saxophone flute head.

Background

Saxophone belongs to a musical instrument widely applied in the family of woodwind music and has the advantages of pure tone, clearness, graceful appearance and soundness and fullness in the tone area. The saxophone head is an important component of saxophone, and at present, after the saxophone head on the market is produced, the shape of the inner cavity of the saxophone head is basically a smooth surface structure, please refer to fig. 9; the tone of the saxophone head is related to the shape of the inner cavity and the reed. In the development process of saxophone performance, in order to improve tone quality, the development and design are generally carried out from reeds. In addition, the inner chamber arranged on the existing smooth surface, particularly the upper surface of the flow guide slope of the mouthpiece chamber opening, gathers a lot of water drops, the water drops are difficult to disperse in the playing process, and the water drops need to be wiped or thrown out after one end of each playing, so that the tone color is reduced.

Aiming at the existing flute head, the utility model improves the airflow distribution of airflow in the air inlet pipe according to fluid mechanics, so that the flute head can emit better tone; in addition, the utility model can also reduce the water vapor accumulation at the mouth of the mouthpiece during the playing process and improve the problem of tone color change caused by water droplet accumulation.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems in the prior art, the utility model provides the saxophone flute head which has a compact structure and a reasonable design, improves the tone quality and reduces the water drops from gathering at the mouth of the mouthpiece.

The utility model is realized in such a way that a saxophone flute head comprises a flute head body which is provided with a through air flow inner cavity, wherein the flute head body comprises a connecting pipe section, an air pipe section and a mouthpiece muzzle, and the bottom of the mouthpiece muzzle is a flow guide slope which inclines towards the air pipe section; the method is characterized in that: the upper surface of the flow guide slope close to the outer end part of the mouth of the blowing nozzle is provided with a plurality of flow guide grooves which are converged from two side walls of the mouth of the blowing nozzle to the center, the flow guide grooves extend from the inlet end of the mouth of the blowing nozzle to the direction of the air pipe section, and convex edges are formed between the adjacent flow guide grooves.

Preferably, the center of the blowing nozzle chamber opening is provided with a flow guide arch along the length direction of the flute head body, and the outer surface of the flow guide arch is provided with a lateral flow guide groove converging to the center of the flow guide arch.

Preferably, the guide arch is of a ridge structure.

Preferably, the distance between the end part of the guide groove positioned in the center and the end part of the blowing nozzle chamber opening is 3-5 mm.

Preferably, the flute head body is a metal flute head or a plastic flute head or a bakelite flute head.

The utility model has the advantages and technical effects that: because the utility model adopts the technical scheme that a plurality of diversion grooves which are converged from two side walls of the mouth of the blowing nozzle to the center and extend towards the direction of the air pipe section are arranged on the upper surface of the diversion slope close to the outer end part of the mouth of the blowing nozzle, and the adjacent diversion grooves are overlapped to form the convex edge, the distribution of the existing flute head airflow entering the air pipe is changed through the design, so that the emitted tone is better and more beautiful; in addition, the utility model can also reduce the water vapor accumulation at the mouth of the mouthpiece during the playing process, and improve the problem of tone color change caused by water droplet accumulation.
