Abstract
A method for producing an apparatus for ejecting liquid droplets includes the steps of providing a porous medium having a plurality of pores therein, forming a plurality of holes through the porous medium and assembling with the porous medium a plurality of transducers and nozzles. At least some of the plurality of pores are in the porous medium, and enable a liquid to flow into a liquid cavity prior to the liquid droplet ejection. Each transducer corresponds to a corresponding liquid cavity, a corresponding nozzle and a corresponding hole, generally disposed along the same axis. Each transducer is operative to eject liquid droplets through the corresponding nozzle via the corresponding hole.
