A droplet delivery device includes a housing with a mouthpiece port or outlet from a nasal device for releasing fluid droplets, a fluid reservoir, and an ejector bracket having a membrane positioned between a mesh with a plurality of openings and a vibrating member that is coupled to an electronic transducer, such as an ultrasonic transducer. The transducer vibrates the vibrating member which causes the membrane to push fluid supplied by the reservoir through the mesh to generate droplets in an ejected stream released through the outlet.

An aerosol generation device includes a circuit or microcontroller for automatically detecting and adjusting vibration frequency of an electronic transducer to a determined resonance frequency that changes during operation of the device whereby the circuit or microcontroller provides a plurality of tuning signal waves at each of a plurality of time intervals during operation of the electronic transducer from comparison of the current measured for each signal wave during each time interval.
