| Abstract(in English) | In this paper, we study a realization of the design support method for compact acoustic systems. Recently, the demand for compact and thin acoustic systems (e.g. mobile phones) has been increasing. The acoustic structure design for mobile phones is getting harder because recent mobile phones are small and have complicated structures. In order to solve this problem, we have already proposed a design support method for compact acoustic systems based on FDTD (finite difference time domain) method and GA (genetic algorithm). However, the proposed method requires long computation time. In this paper, we try to reduce the computation time using CUDA and GPUs (Graphic processor units) and improve the performance using various generation alternation model in the GA. |
