1. A droplet delivery device comprising:
an inhaler outlet assembly including an airflow outlet aperture of a mouthpiece or nostril insertion element;
an ejector bracket including an aperture plate with a plurality of openings formed in the aperture plate, wherein the aperture plate is operably coupled to a vibrating member coupled to an electronic transducer and an exit side of the aperture plate is positioned in or adjacent an airflow channel that exits at the airflow outlet aperture;
a membrane operably coupled to the vibrating member between the vibrating member and the aperture plate, wherein the membrane is a different material from the vibrating member, and wherein the transducer is coupled to a power source and is operable to oscillate the vibrating member and the membrane and generate an ejected stream of droplets through the aperture plate; and
a fluid flow path external to a fluid supply reservoir in fluid communication between a seal of the fluid supply reservoir and the membrane.
