Schematic diagram of the VSB model. (a) The space is divided into the APL in blue and the AML in yellow. The acoustic waves in APL can be manipulated by the tube array in the AML. (b) The amplitude distribution of the acoustic field in the APL. A standing wave field is established on the reflection side, and a dark region is formed on the transmission side.
