This paper describes a method to construct a movable virtual sound source (VSS) from a linear array of parametric loudspeakers. In the proposed method, wave field synthesis is used to construct a focused VSS at any position in air without moving the loudspeakers. The motion of the VSS can be realized by constructing VSSs successively along the moving path. Parametric loudspeakers realize a sharp directivity by exploiting the straightness of ultrasound; therefore, a VSS constructed by the proposed method is expected to be easy to perceive. Compared with a VSS constructed from conventional electro-dynamic loudspeakers, the proposed method can achieve a higher precision when the VSS is moving parallel to the loudspeaker array.
