A piezoelectric inkjet printhead, and a method of manufacturing the same,
includes an ink inlet for allowing inflow of ink, a plurality of pressure
chambers to contain ink to be ejected, the plurality of pressure chambers
being in communication with the ink inlet, a manifold formed in
communication with the ink inlet, a plurality of restrictors connecting
the manifold to respective first ends of the pressure chambers, a
plurality of dampers at positions corresponding to respective second ends
of the pressure chambers, the second ends being opposite the first ends,
a plurality of nozzles in communication with the plurality of dampers for
ejecting the ink, a plurality of actuators for applying a driving force
to each of the pressure chambers for ejecting the ink, a damping membrane
under the manifold for dampening a pressure change inside the manifold
and a cavity under the damping membrane.
