Abstract:
1. A method for correcting stimulation nonuniformity at end area regions of an orifice plate of a droplet generator body, the orifice plate having an array of jets, the droplet generator body having end regions and a central portion, and further having at least one central portion stimulation transducer bonded to the central portion of the droplet generator adjacent to a fluid cavity trench, the method comprising the steps of: bonding at least one end region stimulation transducer in each end region of the droplet generator beyond ends of the fluid cavity trench; using the at least one end region stimulation transducer to drive the end regions of the droplet generator at an amplitude and/or phase different from the amplitude and phase provided by the at least one central portion stimulation transducer; and fabricating at least one acoustic cut in the droplet generator body.
