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.
