PURPOSE:To almost perfectly prevent the discharge of aroma due to natural leakage after the stop of emission, by arranging a short strip like piezoelectric bimorph, wherein the base end part thereof is fixed to the proper place in a container and the leading end part thereof us made free, so as to close an emitting orifice in usual state by a part thereof. CONSTITUTION:When a power source switch 8 is turned ON, piezoelectric bimorphs 51, 52, 53, 54 repeat vibration as shown by an arrow and, therefore, the air of a receiving chamber 3 and the open air get in and out through emitting orifices 41, 42, 43, 44 and the fragrance allowed to fill a container is gradually discharged into the outside, for example, the compartment having an aroma emitting device 1 arranged thereto of a car. When the power source switch 8 is turned OFF, the piezoelectric bimorphs 51, 52, 53, 54 are returned to solid line positions to stop and the emitting orifices are hermetically closed and, therefore, the fragrance is not diffused to the outside at all. Since the fragrance in a room can be arbitrarily controlled by operating only the switch 8, an unpeasant feeling due to excessive supply can prevented. |
