On the basis of investigating the sound field of a plane piston transducer and the relations between sound field and radiation force, by settling four plane piston transducers driven at the same frequency at each corner of a regular triangular pyramid with their sound-beam axes crossing at the center of the pyramid, this technique uses ultrasonic wave synthetic theory to acquire a three-dimensional ultrasonic standing wave field. The micro-component can be captured, transported, released in the range of space by adjusting the phase of the transducers.
