When synthesizing a dynamic sound field using a multichannel loudspeaker array, incorporating moving sound scenes enhances the immersive experience for listeners. Previous studies have explored the synthesis of a moving sound source situated outside the region enclosed by an array of loudspeakers, generally termed a nonfocused moving sound source. This paper presents the synthesis of a moving sound source inside the region enclosed by a loudspeaker array, termed a focused moving source. The driving signals for the loudspeakers are derived using the principle of wave field synthesis. Computer simulations have been conducted to evaluate the effectiveness of the proposed driving signals in synthesizing a focused moving point source.
