ABSTRACT:
A player for a multi-aroma cartridge constituted by a planar array of like frame assemblies held within a multi-section framework, each assembly being formed by a pad of absorbent material sandwiched between a pair of frames whose margins are joined together to define a central zone exposing the pad. The pad of each assembly is impregnated with a liquid fragrance that differs from those of the others. When the cartridge is inserted in a slot in the player case, it lies over a complementary honeycomb, each of whose cells is then in registration with a respective assembly. The cells are provided with individual electric heaters such that when a selected cell heater is energized, it heats the air in the cell to produce a positive pressure therein that acts to force the heated air through the zone to volatilize the liquid fragrance, the resultant aromatic vapor being discharged into the atmosphere through vents in the case. The selection of aromas to be played may be effected manually or it may be synchronized to follow the scenes of a video tape or movie film presentation.
