Analysing a loudspeaker design
A basic analysis of a loudspeaker design consists of analysing the magnetostatic properties of a 2D axisymmetric design. In certain cases, 2D analysis is insufficient because of symmetry breaking features, for example, segmented magnets. In this case, a 3D model is needed. The same analyses can be performed in 3D as with the 2D analysis package.

Loudspeaker optimisation: minimal mass with 1.8 T flux density
This example demonstrates the use of OptiNet with Simcenter MAGNET for the optimisation of a loudspeaker design based on its electromagnetic characteristics. Simcenter MAGNET is used to compute the electromagnetic fields, and OptiNet is used to find the optimum design as specified by the user's requirements..

Analysing a loudspeaker's voice coil response to a signal
In this example, we have analysed the voice coil response to a signal by using Simcenter MAGNET's 2D Transient with motion solver. The solver includes coupling to the mechanical equations of motion, so that the movement of a component of a device (for example, the movement of the voice coil) is accurately simulated. The mechanical effects can include friction, inertia, mass, springs, gravitation, etc.
