Abstract: An aerosol generation device includes a circuit or microcontroller for detecting and adjusting vibration frequency of an electronic transducer to a determined resonance frequency that changes during operation of the device.

Abstract: A droplet delivery device, such as for providing an aerosol for inhalation by users, includes a piezoelectric transducer that vibrates an ejector plate of an ejector mechanism. The device delivers fluid to the ejector plate that is converted to droplets that exit the device as an aerosol. A highly efficient driving circuit is provided that can precisely change the peak-to-peak voltage to the transducer and frequency while also monitoring the current from a stable voltage. Precision control while monitoring the power consumption from the piezoelectric transducer allows for consistent dosing and for the user to tailor their aerosol delivery to their preferences.

Abstract: 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.
