The device for diffusing volatile substances, comprising a casing (1) wherein at least two respective volatile substance containers (2) are housed, said containers (2) being moveable relative to said casing (1) between at least one first position, where one of the containers (2) is exposed to the environment for diffusing its volatile substances, and a second position, where another container (2) is exposed to the environment, and characterised in that between said casing (1) and the container or containers (2) unexposed to the environment a space (3) is defined, which allows the diffusion of volatile substances from the unexposed container or containers (2) to a lesser extent than the container (2) exposed to the environment.It enables performance to be improved due to the fact that two or more fragrances in two or more containers contribute to the final performance and intensity.
