An atomiser system includes a fragrance cartridge and a docking housing in which the fragrance cartridge is installed. The fragrance cartridge includes a bottle for holding a liquid fragrance therein; a wick extending down into the bottle; a piezo disc for atomising the liquid fragrance received from the wick; and an adjustable cap by which a user activates the cartridge, bringing the liquid fragrance into contact with a certain portion of the wick.
