摘　　要：为克服传统方法设计抽指加权叉指换能器的繁杂性,提出了一种全新的抽指加权叉指换能器的设计方法,它模仿生物进化规律,将所设计的抽指加权叉指换能器进行二进制编码,并根据任意给定的目标频率响应曲线和抽指加权叉指换能器的频响特性构造适应度函数,同时考虑抽指加权叉指换能器的指条抽取后的邻近效应,通过排序选择、一点交叉和变异等遗传操作,自动进化出符合任意给定频率响应特性的抽指加权换能器。进化实验结果表明,该设计方法正确有效、实用性强。In order to avoid complexity for designing electrode withdrawal weighting transducer, a new method for designing electrode withdrawal weighting transducer is adopted. The electrode withdrawal weighting transducer is coded by binary code and fitness function is made by using of object frequency re- sponse given by random and characteristics of frequency response of electrode withdrawal weighting transducer, which is included proximity effect. Then, the electrode withdrawal weighting transducer is obtained automatically by sequencing selection, one-point crossover and mutation operation imitating organic evolution. Evolutional experiment shows that the method is correct and practical.
