Preferably, the method further comprises:

the sound amplifying cavity is arranged in the tail end of the horn mouth head and comprises a sound amplifying end and a sound transmitting end;

wherein, the public address end with the tail end of inner wall inboard is connected, the sound transmission end is connected with the one end of whistle pipe.

Preferably, the sound amplifying cavity is in a truncated cone structure.

Preferably, the inner diameter of the sound transmission end is the same as the inner diameter of the whistle pipe.

Preferably, the inner diameter of the sound amplifying end is larger than the inner diameter of the tail end of the inner side of the inner wall.

Preferably, the helical groove comprises a first portion and a second portion;

the first part is parallel to the central axis of the nozzle head, one end of the second part is connected with the first part, and the other end of the second part is obliquely arranged along the outer side of the inner wall.

Preferably, the groove depth of the spiral groove is 2 mm-3 mm, and the groove depth of the second portion is greater than the groove depth of the first portion.

Preferably, the inner wall and the outer wall are detachably connected.

Preferably, the whistle pipe and the horn mouth head are integrally formed.

The beneficial effects of the utility model are as follows:

according to the trombone mouthpiece provided by the utility model, the plurality of cavities are formed between the spiral grooves and the inner wall on the outer side of the inner wall of the mouth head, so that when sound passes through the inner wall, the sound can be vibrated and reinforced for a plurality of times, and then the sound is further reinforced by combining the structure of the sound amplifying cavity, so that the tone brightness is improved, the total sound pressure can be increased, the mouth is suitable for beginners, and the difficulty of playing by the beginners is reduced.
