Design of fourth-order band-pass loudspeaker systems based on simulated annealing genetic algorithm

DONG Yong-zheng, ZHOU Jing-lei, SHEN Yongcs, Nanjing University, Jiangsu Nanjing 210093, China)  
Coordination of parameters is required in the design of fourth-order band-pass loudspeaker systems, making the design process complicated. In this article, the simulated annealing genetic algorithm (SAGA) which combines simulated annealing and genetic algorithm is used to design fourth-order band-pass loudspeaker systems. SAGA has the ability of overall searching and avoids the premature convergence and low efficiency in the search. The algorithm speeds up convergence. The effect of leakage losses is considered and a method to measure the Q value of leakage losses is proposed. A comparison of measured data and the theoretical curve shows that the SAGA method can meet the design requirements.
