Abstract
A liquid droplet production apparatus comprising a perforate membrane (33,39), a means for supplying liquid to one side of the membrane, an actuator (31) for vibrating the membrane said vibration causing liquid droplets to be ejected from the other side of the membrane, in which magnetic force is used to connect the actuator to the membrane so that the vibration can be transmitted.
