Abstract
A method and device for generating synthetic vortex sound field (SVSF) with more mode number includes the following steps: (1) a transducer array composed of N transducer units is constructed, and each transducer unit emits a sound field to generate an initial sound field; (2) at the same time, the position of the transducer unit and the phase of the sound field emitted by each transducer unit are changed, and each change produces a sound field, and thus changings times produces of sound fields, wherein the way to change the position of the transducer unit is to rotate the transducer array as a whole; (3) the initial sound field is superimposed with s of sound fields generated in step (2), to obtain SVSF with more mode number. The method and device for generating vortex sound field (VSF) can be used for underwater communication or acoustic imaging.
