AB  - Multiphysical simulations of loudspeakers have been investigated by scientific and industrial researchers for more than 40 years. At a first glance an electrodynamic loudspeaker seems to be a fairly simple assembly—a simple (sub-)system compared to typical applications of modern CAE methods. So where is the challenge? In detail! Besides strongly coupled different physical domains (electromagnetics, mechanics, acoustics, thermal transport, fluid dynamics ...), we also have to deal with path dependent dynamic effects and nonlinearities (including instabilities) in each domain. Additionally, materials with totally different behavior (and thus totally different material models to be used) and different joining techniques for each component are used as well. This paper will summarize challenges for realistic simulations and will discuss efficient solutions for daily usage in the industrial work flow of product development.
