Abstract
The utility model discloses a trombone comprising a trombone unit having a mouthpiece, a sliding tube and a trombone body. The air outlet end of the mouthpiece is connected with the air inlet end of the sliding tube. The trombone body comprises a main tube and a bell with the air inlet end connected with the air outlet end of the main tube. The trombone also comprises an auxiliary tube and a turning valve piston which provides two air paths and enables the two air paths to be switched selectively. The air outlet end of the sliding tube, the air inlet end of the main tube, the air inlet end of the auxiliary tube and the air outlet end of the auxiliary tube are all connected to the turning valve piston. One air path provided by the turning valve piston is a straight-through air path which directly makes the air outlet end of the sliding tube and the air inlet end of the main tube communicated and the other air path provided by the turning valve piston is a bypass air path which indirectly makes the air outlet end of the sliding tube and the air inlet end of the main tube communicated through the auxiliary tube. Compared with the conventional trombone, the trombone has the advantage that the two air paths provided by the turning valve piston can be switched selectively for sounding, so that the sound effect is diversified. The sound changing operation is simple and easy to perform and the trombone is practical.
