An ultrasonic control apparatus and method for a liquid jet are provided. An ultrasonic generator is equipped with two sets of ultrasonic transducers arranged perpendicularly to each other, and the two sets of ultrasonic transducers emit ultrasonic waves of a specific frequency. Two sets of reflectors are arranged correspondingly in front of the ultrasonic waves emitted by the two sets of ultrasonic transducers, where a distance exists between the ultrasonic transducers and the corresponding reflectors, two stable standing wave sound fields are formed by adjusting the distance. A liquid jet device is equipped with a nozzle that emits a continuous jet, where the nozzle is located above an intersection of pressure nodes of the two standing wave sound fields, and the two standing wave sound fields act on the liquid jet to adjust jet morphology under the action of acoustic radiation pressures.
