The systematical equations using to control the trapped particles in 3D space of acoustic-optical tweezers is introduced. The factors influencing on the position of trapped particles in 3D space is discussed. The trajectories of trapped particle under the different single tweezers are theoretically observed by the change of acoustic frequency. The obtained results show that the acoustic frequency be the only factor used to control the trapped particles in 3D space, different from the classical optical tweezers, which uses two facts at least.
