Abstract
A liquid droplet production apparatus includes a perforate membrane, with liquid being supplied to one side of the membrane. An actuator for vibrating the membrane is provided. The vibration causes liquid droplets to be ejected from the other side of the membrane. Magnetic force is used to connect the actuator to the membrane so that the vibration can be transmitted.
