Asymmetric acoustic manipulations (AAMs) attract increasing attention for applications in integrated and architectural acoustics. However, because a planar phased array system has the same phase distribution on both sides, designing monolayer device with asymmetric modulation is real challenge. This work experimentally realizes four types of prisms different AAM effects arising from distributions, created by exit interfaces either side prism. With broad bandwidth, multifunctional AAMs, passive structure, easy fabrication, these offer fresh approach to creating $e.g.$ rectifiers diodes.
