扬声器单元参数计算的三元素法

"Three Factor Method"for Loudspeaker Parameter Solving

提出了由扬声器的3个已知参数计算其它6个参数的18种可能的情况,并给出了利用Matlab解符号方程得出的具体的18组解。这些结果对于有预定要求的设计或改进工作可以提供理论指导。最后讨论了用设定额外参数值来代替在相关约束条件下求解不定方程组的一种实用方法。

Eighteen possible situations that all the other main parameters of a loudspeaker be deduced by its three known parameters are proposed. All the eighteen groups of solution which obtained by Matlab software, are given in detail. The results can be a theoretical guidance for loudspeaker designing or improving when some parameters are preset. An alternative practical method of supposing additional parameter value is discussed finally in case the solution should be obtained by solving indeterminate equations under related restraint conditions.
