ABSTRACT:
A breath controller for musical instruments includes a mouth piece for blowing the air into an air chamber. Blowing the air makes an air pressure increase in the air chamber, thus an elastic member is displaced corresponding to the air pressure. At the same time, the displacement of a reflection surface changes an amount of light to reflect an emitted light from a light-emitting element to a light-receiving element. The light-receiving element then controls a signal corresponding to the amount of light, thus making the signal change to a musical tone signal.
