A combination aroma diffuser includes a lower housing, a control unit, a display screen, an upper housing, a light-emitting heating unit, a cover member and a speaker. The upper housing and the lower housing admits light so that the displayed digits of the display screen that is kept inside the lower housing are visible when the display screen emits light. The control unit has stored therein music and sounds for output through the speaker. The light-emitting heating unit emits light through the upper housing to heat an aromatic fluid in the cover member into vapor that goes out of air vents of the cover member to the outside open air.
