The flute tube is provided with a sound hole. The flute mouth is placed on the top of the flute tube. The outlet, the airflow outlet and the blowing channel are arranged in a vertical direction, and a wedge-shaped airflow splitter block is formed at the airflow outlet on the outer wall of the mouthpiece, and the airflow splitter is set opposite to the blowing channel. The outlet communicates with the flute and forms an air passage for air discharge;

所述气流分流块楔形顶端与吹气通道高度平分线平行；The wedge-shaped top of the air flow splitter block is parallel to the height bisector of the blowing channel;

所述笛管与笛嘴为可拆分式结构；The flute pipe and mouthpiece are detachable structures;

笛管为圆锥中空管，笛嘴与所述圆锥笛管圆周长数值大的一端部活动连接；The flute tube is a conical hollow tube, and the flute mouth is movably connected to the end with a larger circumference of the conical flute tube;

所述的笛嘴顶部呈半U型。The top of the mouthpiece is half U-shaped.

采用上述结构后，楔形气流分流块的设置，使经过吹气通道的气流在分流块楔形顶端实现分流，一部分从笛嘴外壁的气流排出口排出，另一部分从笛管末端或音孔排出，如此结构的笛子发音更清脆、明亮，笛嘴与笛管采用一分为二的拆分式结构，可分别选择不同的材质，这样更易于注膜及成型，生产工艺简单，制造成本低，便于工业化大批量生产。After adopting the above structure, the setting of the wedge-shaped air flow diverter block makes the air flow passing through the blowing channel split at the wedge-shaped top of the diverter block, part of which is discharged from the air outlet on the outer wall of the flute mouth, and the other part is discharged from the end of the flute pipe or the sound hole, so The structure of the flute sounds crisper and brighter. The mouthpiece and the flute tube adopt a split structure that is divided into two parts. Different materials can be selected separately, which is easier for film injection and molding. The production process is simple, the manufacturing cost is low, and it is convenient for industrialization. Mass production.
