Patent ID: 8480208

Claim:
A liquid-droplet ejection head comprising: a nozzle substrate comprising a plurality of nozzles; a chamber substrate formed on the nozzle substrate and comprising a plurality of liquid chambers connected to the respective nozzles, a plurality of diaphragms forming part of the plurality of liquid chambers, and a plurality of electro-mechanical transducers mounted on the diaphragms corresponding to the plurality of liquid chambers; a liquid supply substrate formed on the chamber substrate and comprising a plurality of liquid supply channels through which liquid is supplied to the plurality of liquid chambers in the chamber substrate; a frame substrate formed on a first face of the liquid supply substrate opposite a second face of the liquid supply substrate formed on the chamber substrate; a driving circuit member mounted on the frame substrate that drives the plurality of electro-mechanical transducers; and a plurality of wire members connecting the plurality of electro-mechanical transducers to the driving circuit member, wherein a voltage applied to the electro-mechanical transducers through the plurality of wire members deforms the electro-mechanical transducers and the diaphragms to generate pressure in the liquid chambers.
