ABSTRACT:
An air responsive control forms the basis for a mouth-blown device having a series of pipes in side-by-side relation into which the user blows or sucks. Signals are produced to operate apparatus such as a music synthesizer for a typewriter or computer. Each pipe has at least a section of light transmitting material. Inside that section, movable actuator such as a ball moves out of a light path between a light source and a photo-sensitive responder by sucking on or blowing by an operator. When the ball blocks the light path there is now signal to the operated apparatus but when it moves out of the light path there is a signal. Both the light source and the photo-sensitive responder are outside the pipe, thus ensuring that there is no contact with saliva of any directly connected electrical part.
