1. A droplet generating method comprising:
generating a flow of a first liquid contained in a liquid driving device;
directing the flow of the first liquid into a micro-pipe including a vertical portion extending along a longitudinal axis, the portion having an outlet end;
passing the first liquid from the outlet end of the micro-pipe;
directing the first liquid from the micro-pipe into a container positioned at least in-part below the outlet end, the container holding a second liquid including a liquid surface disposed at a position located between a highest position and a lowest position; and
forming a plurality of droplets of the first liquid emitted from the outlet end by vertically vibrating the micro-pipe along the longitudinal axis between the highest position and the lowest position.
