Abstract
Improved whistle, characterized essentially by the fact that it is constituted by a single-piece body of aerodynamic shape that integrates a cavity provided with a single transverse opening, located later to an angle of attack that forms the body of the ito, said cavity being designed for receiving the current of air, whose current, after following a rotational path through the interior of the cavity of said whistle, exits to the outside by said single opening, colliding with the inlet current and producing a loud whistle.
