Abstract
A continuous drop emitter includes a liquid supply chamber containing a liquid held at a positive pressure. First and second nozzles are in fluid communication with the liquid supply chamber and emit first and second continuous streams of a liquid. First and second stream break-up transducers independently synchronize the break up of the first and second continuous streams of the liquid into first and second streams of drops. An acoustic damping material is located adjacent to or within the liquid supply chamber for damping sound waves generated within the liquid chamber by the first and second stream break-up transducer. The continuous drop emitter can be configured with a Helmholtz resonant chamber tuned to a critical stimulation frequency having an acoustic damping material located therein.
