A computer then adds up all the individual behaviors to predict the behavior of the part.įigure 1: Speaker design with ANSYS Multiphysics.įEA can be used to predict the behavior of a part or assembly due to mechanical stress, vibration, fatigue, heat transfer, and even fluid flow (e.g., ferrofluid in the voice coil gap or turbulent air noise in a vent). Mathematical equations help predict the behavior of each element. FEA techniques work by breaking down a component into a number of finite elements (e.g., little cubes). FEA can predict whether a part or assembly will break, wear out, or hopefully work the way it was intended. (ANSYS was founded in 1970 and has nearly 3,000 employees.) These programs are used to predict how something will react to real-world forces, vibration, heat, fluid flow, and other physical effects. And, the speaker industry has the popular LOUDSOFT FINE series of software simulation programs that include acoustics, crossover design, cone/diaphragm, magnetics, and thermal modeling.Īlthough LOUDSOFT’s simulation software is well known in our industry, in military and industrial engineering, the leading and most sophisticated simulation software are ANSYS and COMSOL. In the 1990s, LEAP and other speaker design software grew in sophistication, enabling users to predict the impact of manipulating speaker driver parameters, band-pass enclosures, passive radiators, and crossover networks.įor the most sophisticated design efforts, there are now magnetic circuit design software and finite element analysis (FEA) cone and thermal prediction simulation software. With the introduction of the IBM PC and DOS operating system in the early 1980s, Thiele-Small (T-S) simulation software for enclosure design became a must-have for speaker system designers (e.g., autosound installers, pro-sound, commercial speaker, and stereo and home-theater speaker designers).
