Disclosed herein is a delivery system or apparatus for the production, evaporation or release and wide dispersion of volatile materials using an electromechanical transducer or electromechanical transducer, wherein the transition from droplets to the molecular level of the volatile material is assisted by an air disturbance generator. By increasing the rate of droplet disintegration and the emission or release of the volatile materials, higher detection of the less volatile components is achieved, resulting in higher volatile material concentration and improved hedonics, thus delivering an improved method of dispensing such volatile materials. The system is highly energy efficient and capable of battery operation.
