air driven sonic Zambomba.

摘要

sound Zambomba air driven, characterized in that, inside the cylindrical soundboard coaxially sympathizes a cylinder, inside which a piston whose stem protrudes centrally through the cover of the soundboard, simulating cane zambomba, although with the possibility of upward-downward axial movement, limited by the piston stroke inside the cylinder, which propels air in either direction, to exit through some whistles attached radially in the cylinder preferably at the end areas not swept by the piston.
