1. An acoustic force assisted painting system comprising:
a housing having a conduit configured to receive paint from an external source;
a nozzle disposed in the housing, the nozzle having an inlet that is fluidly connected to the conduit and configured to receive paint from the conduit, the nozzle having only one outlet configured to dispense the paint, a first diameter of the nozzle inlet being larger than a second diameter of the nozzle outlet; and
at least one first transducer disposed in the housing at a location downstream of the nozzle outlet in a flow direction of the paint, the at least one first transducer being spaced from the nozzle, the at least one first transducer emitting an acoustic force toward the paint dispensed from the nozzle outlet and increasing a velocity and a kinetic energy of the dispensed paint with the emitted acoustic force.
