中文摘要:
      四阶带通式扬声器系统对扬声器单元参数和箱体参数的配合要求较高,设计复杂。文章中将模拟退火算法和遗传算法相结合,提出了运用具有全局搜索能力的模拟退火遗传算法(SAGA)来设计四阶带通扬声器系统的方法,该算法避免了单一遗传算法存在的早熟收敛和搜索效率较低等问题,提高了算法的收敛速度。文章中考虑了声导管泄漏损耗的影响,并提出了泄漏损耗的QL值的实际测定方法。测量结果表明理论曲线与实测曲线相吻合,说明模拟退火遗传算法能达到设计要求。
英文摘要:
      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.
