当步骤S1034中第三仿真曲线与第三基准曲线一致时，执行步骤S1036，即判断第二仿真曲线与第二基准曲线是否一致；步骤S1036的具体包括以下步骤：
步骤S10361：判断第二仿真曲线与第二基准曲线之间的偏差的绝对值是否大于第五预设值；
当第二仿真曲线与第二基准曲线之间的偏差的绝对值大于第五预设值时，即第二仿真曲线与第二基准曲线不一致，执行步骤S10362：判断第二仿真曲线与第二基准曲线之间的偏差是否大于第五预设值；
当第二仿真曲线与第二基准曲线之间的偏差大于第五预设值时，由于第五预设值为正数，且第二仿真曲线与第二基准曲线之间的偏差绝对值大于第五预设值时，即为第二仿真曲线高于第二基准曲线，那么执行步骤S103181：将线性振动马达的初始阻尼系数C1以及触控悬浮系统的初始阻尼系数C2分别增大第九数值，生成线性振动马达的修正阻尼系数C1 1以及触控悬浮系统的修正阻尼系数C2 1；
当第二仿真曲线与第二基准曲线之间的偏差小于第五预设值时，由于第五预设值为正数，且第二仿真曲线与第二基准曲线之间的偏差绝对值大于第五预设值时，因此第二仿真曲线与第二基准曲线之间的偏差小于第五预设值的相反数，即第二仿真曲线低于第二基准曲线，那么执行步骤S10382：将线性振动马达的初始阻尼系数C1以及触控悬浮系统的初始阻尼系数C2分别减小第九数值，生成线性振动马达的修正阻尼系数C1 1以及触控悬浮系统的修正阻尼系数C2 1；
其中，步骤S10381以及步骤S10382为步骤S1038的具体步骤，即根据不同的情况针对性的修正线性振动马达的初始阻尼系数C1以及触控悬浮系统的初始阻尼系数C2。
步骤S1036具体步骤是具体介绍了第二仿真曲线与第二基准曲线是否一致的具体过程，而步骤S1038是当第二仿真曲线与第二基准曲线不一致时，修正等效参数的具体过程。
当完成对初始等效参数进行修正之后，输出的修正参数可能全部为初始等效参数（即五个判断项目中全部都是一致的），也有可能为部分为初始等效参数，部分为修正等效参数，例如输出的修正参数为：线性振动马达的修正阻尼系数C1 1、触控悬浮系统的修正阻尼系数C2 1、线性振动马达的修正等效电感Li 1、线性振动马达的修正直流参数Ri 1、线性振动马达的修正劲度系数K1 1、触控悬浮系统的修正劲度系数K2 1、线性振动马达的质量m1、线性振动马达的电磁力系数BL、触控悬浮系统的质量m2，即初始等效参数中的线性振动马达的初始直流参数Ri，线性振动马达的初始阻尼系数C1、线性振动马达的初始等效电感Li、线性振动马达的初始劲度系数K1、、触控悬浮系统的初始劲度系数k2以及触控悬浮系统的初始阻尼系数C2全部进行了修正。
当输出修正后的等效参数时，当将修正后的等效参数输入仿真模型中进行仿真测试时，仿真的系统响应频响曲线与实际结构频响曲线可能依然存在偏差，那么为了尽可能的降低偏差，提高后续线性振动马达短信号的仿真精度，当完成一次对等效参数的修正后，即步骤S101-步骤S104全部完成后，再一次进行修正，即步骤S104输出修正等效参数后再将修正等效参数输入仿真模型中进行仿真测试，即执行步骤S10，进行第二次的等效参数修正。
至于等效参数的修正次数可以根据实际情况来进行选择，例如当修正第二次完毕之后，进行第三次的修正时，五个判断项目均是一致，即第三次修正的过程已经不会对等效参数进行修正了，因此也不必再进行第四次修正了。但是修正第二次完毕之后，进行第三次的修正时，五个判断项目中依然有三个以上判断项目为不一致，那么当第三次修正之后，还需要再进行一次第四次修正。
当然，对等效参数进行多次修正时，可以当等效参数全部修正一次之后再进行一次统一修正，也可以为：当每一项等效参数修正一次之后即可返回进行第二次修正，直到该项的等效参数修正后的判断项目为一致时，再进行下一项的等效参数的修正，如图4所示：
当第二仿真频率点与第二基准频率点不一致，以及第三仿真频率点与第三基准频率点不一致时，对触控悬浮系统的初始劲度系数K2以及线性振动马达的初始劲度系数K1完成修正之后，先不执行步骤S1032：即判断第一仿真曲线与第一基准曲线是否一致；而是将修正后的触控悬浮系统的修正劲度系数K2 1以及线性振动马达的修正劲度系数K1 1与线性振动马达的质量m1、线性振动马达的电磁力系数BL、线性振动马达的初始直流参数Ri，线性振动马达的初始阻尼系数C1、触控悬浮系统的质量m2以及触控悬浮系统的初始阻尼系数C2再一次输入仿真模型中进行仿真测试，获取仿真曲线，即执行步骤S102，然后再执行步骤S103中的步骤S1031：判断第二仿真频率点与第二基准频率点是否一致、以及第三仿真频率点与第三基准频率点是否一致；然后再继续进行执行后续步骤。直到第二仿真频率点与第二基准频率点一致、以及第三仿真频率点与第三基准频率点一致时再进行修正其他等效参数。
