The new ultrasonic vibration mist system composed of longitudinal vibration transducer and flexural vibration disc is proposed in this paper. The resonance property and the design method of the new system are got through theoretical and FEM analysis. It was proved by experiment that the new system mainly works in loading resonance state. The resonance frequency of the new system is mostly depended on the structure of transducer. The output amplitude of the new system increases with the approaching of the resonance frequency between the longitudinal vibration system and the flexural vibration disc.
