An ambient fragrance dispenser comprises a body that defines a container (2) containing a first fragrancing agent, to which membrane diffuser means are applied so as to allow said first fragrancing agent to be diffused from said container (2) towards the area outside of said body. Advantageously, a first outer portion (3) of said body is impregnated with a second fragrancing agent that is diffused towards the area surrounding said body independently from the diffusion of said first fragrancing agent.
