Finite element analysis method for dipole electromagnetic transducer

The invention provides a dipole electromagnetic transducer finite element analysis method, which comprises the following steps of: establishing a three-dimensional finite element model of a transducer, and simplifying the three-dimensional finite element model; performing axial symmetry simplification processing on the transducer three-dimensional finite element model; endowing a three-dimensional finite element model with the material type corresponding to each structure; different physical fields are set according to different functions of the transducer; establishing a multi-physical coupling field; and carrying out finite element analysis and calculation to obtain a sound field generated by the transducer under the driving of the current and the sending current response of the transducer. Compared with the prior art, the finite element analysis method for the electromagnetic transducer has the advantages that the sending current response of the transducer can be accurately obtained in a step-by-step coupl
