The device for diffusing volatile substances comprises means for generating an air stream, and is characterized in that said means for generating an air stream comprise a flexible sheet (1) and at least one piezoelectric element (2), such that said piezoelectric element (2) causes said flexible sheet (1) to expand and shrink to generate the air stream. It allows generating an air flow that is adapted to the geometry of the evaporation surface. |
