The principle objective of the paper is to study the acoustic radiation problem of the 3D space domain
with control boundary. By using the conformal transformation theory, the Green’s function for acoustic point
source in the control domain space is obtained. With it, the expression of acoustic radiation function of the control
domain is formed. Discussion about the acoustic radiation of pulsating sphere in right-angle space is drawn in the
end, including the acoustic radiation directivity effect by the boundary characteristics, acoustic radiation frequency
and acoustic source location. Numerical results show that: for the lower frequency radiation, the infection of free
surface is significant; for the high frequency radiation, the infection of location is significant on the contrary. The
research provides a new method for boundary characteristic problem of the structural-acoustic acoustic.
