PROBLEM TO BE SOLVED: To obtain an acoustic ink jet print head in which efficiency is enhanced substantially while reducing the cost by eliminating high power consumption, generation of an RF signal is integrated on the print head, and unevenness of print quality is eliminated. SOLUTION: The acoustic ink jet print head 40 comprises a plurality of transducers 42 generating an acoustic wave, a plurality of RF power amplifiers 46 corresponding to the plurality of transducers, respectively, and an RF frequency generator 44. The RF frequency generator 44 is connected electrically with each of the plurality of transducers 42 through a corresponding RF power amplifiers 46. The plurality of transducers 42, the plurality of RF power amplifiers 46 and the RF frequency generator 44 are integrated entirely on the acoustic ink jet print head 40.
