Finite element acoustic loudspeaker software
WebUnless that software has been designed to exploit the true generality of the method, the analyst will become frustrated by the gap between the method's theoretical potential and the unnecessary limitations imposed by the software. This is where Abaqus shines. Abaqus is truly a general-purpose finite element-based software package. WebAug 21, 2013 · We present a hybrid method for modeling the acoustic characteristics of a loudspeaker driver. The method uses an electroacoustic lumped circuit model for the magnet, voice coil, and spider system. This includes the electrical and mechanical properties. The lumped model is coupled to a finite element (FE) model of the speaker …
