The invention refers to an oscillate, plate on hinge with channel and steel slide with double action producing the sound in the accordion. The channel, according with the invention, is an iron (thin plastic) plate (1) (Fig. 1) where is pressed a channel (2). The plate (1) caught through a hinge (6) moving with air's help, as well as a slide (3) riveting (4) by the rod (5), slide must be always in the channel (2) vibrating at the air passing (E) , (E') producing the sound. This is also made as: the plates (1) (Fig. 2) positions (A2), (B2) - with the slide (3) riveting (4) on it, are fixed between two air's chambers (F) ,(G) having the orificies (5) (7) (9) (11) where are working the admission valves (6) , (12) and repression valves (8), (10), conducting the air, represented by the arrows (E) , (E') making work the slide (3) through channel (2) vibrating, producing the sound of the accordion. |
