(接2011年35卷8期第19页)4.1非线性电-力系统电-力系统中的电学与力学状态变量决定了输入功率转换成热的量。图5中的等效电路考虑到了电动式扬声器主要的非线性机理,如:与音圈位移x有关的力因数Bl(x),劲度Kms(x)以及电感Le(x)。
(Received 2011 Vol. 35, No. 8, Page 19) 4.1 Nonlinear Electric-Force Systems The electrical and mechanical state variables in electro-mechanical systems determine the amount of input power converted to heat. The equivalent circuit in Figure 5 takes into account the main non-linear mechanisms of the electrodynamic loudspeaker such as the force factor Bl (x), the stiffness Kms (x) and the inductance Le (x) associated with the voice coil displacement x.
