A scent emitting device incorporates a specially adapted prerecorded playback cassette and playback device, with the prerecorded cassette including one or more scent emitting cartridges and the playback device including scent dispersal apparatus. The recording includes inaudible and/or invisible signals which trigger the scent production mechanism of the player to actuate the scent emitting apparatus. Upon receiving an appropriate signal from the recording, the apparatus actuates a small pump which withdraws a small quantity of the desired scent from the appropriate scent cartridge and sprays the selected scent into a plenum, whereupon it is vaporized and dispersed into the ambient air by a fan or other suitable device. Each prerecorded cassette may include one or more (preferably several) scent cartridges, with the player preferably including a series of syringes for automatically penetrating each cartridge of the cassette as it is inserted into the player.
