An aromatic nebulizing diffuser includes a base panel, a lower housing, power adapter, an electric fan, a speaker, a music control circuit, an ultrasonic oscillator carrying a light source, a fluid container, a waster shutter and a transmissive cover. When electrically connected, the ultrasonic oscillator is started to generate high frequency sound waves and to cause atomization of the aromatic fluid contained in the fluid container so that a mist of aerodynamic breakup of fine water drops is seen through the transmissive cover and at the same time, the music control circuit outputs a music through the speaker and the light source emits a mixed color of light to light up the mist of aerodynamic breakup of fine water drops that is forced out of the hole on the top side of the transmissive cover.
