Wind musical instrument equipped with slide and supporting system for assisting player in performance

摘要

A player changes the pitch of tones produced through a trombone (10) by controlling the breath and a slide (11a), and the control of slide (11a) is not easy for children, handicapped persons and old players; a supporting system (20) is combined with the trombone (10), and includes a manipulating board (20a) fitted to an appropriate portion of the trombone (10) close to the slide (11a), a driving mechanism (21) connected to the slide (11a) and a controlling unit (22) connected to the manipulating board (20a) and driving mechanism (21); when the player wishes to change the pitch of tones through the sliding motion of the slide, he moves a lever (26) on the manipulating board (20a) by a distance shorter than a target stroke of the slide (11a), and the controlling unit (22) calculates the target stroke so as to supply a driving signal (S2, S3) to the driving mechanism (21); and the driving mechanism (21) exerts force on the slide (11a) so as to assist the player in varying the length of the column of air.
