Analysis of unique loudspeaker driver possible only with multiphysics modeling

Rod Habeshaw, SFX Technologies Ltd.

While we traditionally think of loudspeakers as separate boxes, SFX Technologies Ltd. (Dunfermline, Scotland) have developed loudspeakers that use surfaces – from a tabletop to walls, mirrors, dashboards, and billboards– to produce high-quality sound. When a GA (Gel Audio™) transducer is placed against a surface, this becomes the loudspeaker.

When designing new transducers, simulations are necessary to find the optimal assembly-the right amount of gel and the best way to attach it to the surface. SFX Technologies Ltd is using COMSOL Multiphysics to design these.
