Geometry design of acoustic components, such as horns and surrounds, is time-consuming and complicated. A design process is introduced in this paper to shorten the design-test-optimize cycle. There are three parts in this design process. First part is geometry parameterization. Formulas to build the shape of geometry are given, from 2D profile to 3D geometry. In the second part, acoustic property of the acoustic components is simulated, for example the sound pressure level (SPL) is advised to study in most acoustic components design. Optimization is carried out in the third part. With the help of particle swarm optimization (PSO) algorithm, the geometry parameters are modified to improve acoustic property. We take horn as an example in this paper. But the parametric geometry and optimization method above is highly flexible and can be performed in diverse structures, such as acoustic diffuser and port, etc. The whole process is assembled in one software, which makes the design program easy to handle and high-efficiency.
