Abstract
A pulsed liquid droplet ejecting apparatus array wherein rectangular piezoelectric transducers are arranged abaxially over ink containing chambers. An edge of each transducer is fixed against a reaction block so that on excitation of the transducers by electrical pulses, the transducers extend into the ink chamber ejecting a drop. An improved method for rigidly mounting the piezoelectric transducers to the reaction block for improved efficiency is disclosed. Further, the design includes an improved mechanical crosstalk reducing member comprising a rigid member containing a void.
