ABSTRACT:
A drop transfer system has a plurality of acoustic transducers capable of generating acoustic waves. A plurality of spacing components are located between at least some of the acoustic transducers. A controller is placed in operative connection with the acoustic transducers and configured to activate the acoustic transducers in a phase relationship with each other. The acoustic transducers are positioned in relationship to each other and are operated in the phase relationship to have at least some of the acoustic waves converge at a selected point at a selected time.
