Concertina/accordion construction having casings moving relative each other with support mechanism providing set trajectory and inner note mechanism fed two way air flow/obscurer.

摘要

The wind instrument construction has an air flux circulating in two directions. There are casings (2,3) moving one with respect to the other, and closing and opening between them. There are a set of notes produced inside the casing, and an obscurer drive which opens and closes, providing air or not to the note producers. The casing outer has button pushes mounted on the moving sections. Movement of the casings follows a set trajectory using a support mechanism.
