摘    要:作为一般讨论,曾有专文介绍含磁液磁路系统中,音圈的静力学特性和动力学特性.在研究含磁液的磁路(磁回路)系统中音圈的运动时,是将磁液看作为不可压缩黏性液体的,这种不可压缩黏性流体就是通常所谓的牛顿流体.一般情况下,磁液可认为是牛顿流体,但是,它在高磁场、低粘度、磁液中磁性粉末具有一定大小分布等的情况下,会表现出非牛顿流体的特性.因此,着重介绍了磁液的非牛顿特性对音圈运动特性的影响.

关 键 词:磁液  非牛顿液体  音圈  运动特性

Abstract:The mechanical features of the voice coil, both static and dynamic, were introduced generously in other reviews concerning magnetic paths with magnetofluid. When studying the motion of the voice coil in magnetic.pathsor circuits containing magnetofluid, we generally consider magnetofluid as incompressible and viscous, that is the Newtonian fluid. However, it may perform non-Newtonian characteristics when the magnetic field strength is high, the viscosity is low and the magnetic particles are of a certain range of volume and distribution. Therefore,this artccle particularly introduces the influence of non-Newtonian properties of magnetofluid on the motion of the voice coil.
Keywords:magnetofluid   non-Newtonian fluid   voice coil   dynamic characteristics
