Loudspeaker
A woofer is made from, a cone-shaped diaphragm with a voice coil wound around its apex. When an electric signal is applied to the coil, the coil and the cone start vibrating, creating sound with the same frequency as the signal.This model computes the coil’s electrical impedance and then feeds this data into an analysis of the cone’s structural displacements and the resulting sound-pressure distribution. This is a two-way coupling as there is a pressure force on the cone.
It shows COMSOL Multiphysics' ability to couple different physical phenomena with each other, and introduces some new modeling templates found in the Acoustics Module.
