Important characteristics for the sound quality of loudspeakers like frequency response and directivity are determined by the size, geometry and material parameters of the components interfacing the acoustic field. The higher-order modes after cone break-up play and important role in wideband transducers and require a careful design of the cone, surround and other soft parts to achieve the desired performance. Finite Element Analysis is a powerful simulation tool but requires accurate material…
