Tone-changing trombone with four tones

Abstract

The invention relates to a tone-changing trombone with four tones, mainly comprising a trombone mouth, a stay tube, a primary conical piston, a primary auxiliary pitch pipe, a main pitch pipe and a trombone opening which are connected in sequence, wherein the air outlet of the stay tube and the air outlet of the primary auxiliary pitch pipe are respectively connected with a conical outer cover end of the primary conical piston; the air inlet of the primary auxiliary pitch pipe is connected with a bottom cover end of the primary conical piston; the bottom cover end of the primary conical piston is connected with a bottom cover end of a secondary conical piston by a short pipe; an air outlet of a secondary auxiliary pitch pipe is connected with the bottom cover end of the secondary conical piston; the air inlet of the secondary auxiliary pitch pipe and the air inlet of the main pitch pipe are respectively connected with a conical outer cover end of the secondary conical piston; and the secondary conical piston is linked with a secondary piston key by a secondary connecting rod mechanism. The tone-changing trombone has the advantages that the structure design is scientific and reasonable, the free switching of the four tones is realized, the pitch range is expanded, and the expressive force of the trombone is richer so as to provide larger exerting space for a player.

Description

technical field [0001] The invention relates to a trombone in the field of western musical instruments, in particular to a trombone with four tones. Background technique [0002] The trombone is a Western musical instrument with rich expressiveness, which is widely used in the performance of military music. Its sound is loud and lively, full of shocking power, and is generally loved by people. The existing two-tone transposition trombone is mainly composed of a mouthpiece, a pull pipe, a conical piston assembly, a sub-tuning tube, a main tuning tube and a bell mouth, and the conical piston assembly is composed of a conical piston, a connecting rod mechanism, Composed of piston buttons, the conical piston is linked with the piston button through the linkage mechanism, the air outlet of the pull pipe and the sub-tuning tube are connected with the conical cover end of the conical piston, the air inlet of the sub-tuning tube and the main tuning tube The air inlets of the tubes ...
