摘要：
An ink jet print head is provided having a nozzle forming substrate with a plurality of nozzles formed therein. Vibrators formed on a piezoelectric transducer disposed within the ink jet print head opposite the nozzles are independently drivable. A first gap is formed between the nozzle forming substrate and a vibrator in a region adjacent the nozzles. A second gap is formed between the nozzle forming substrate and a vibrator at a region away from the nozzles having a different dimension than the first gap.
