Toy whistle, characterized essentially by the fact that it comprises a longitudinal groove, so that when blowing on the whistle obstructing the sound element of the whistle, the emitted air is forced to pass through a longitudinal groove niche, affecting the blades of a small turbine provided for this purpose, at the opposite end of the whistle, printing a turning movement thereto, said turbine being mounted on a cone-tipped shaft and integral with one of a circular piece which is itself a carrier of the corresponding element mobile, rotating in accordance with the rotary movement of the turbine.
