It USES two 15-inch bass and a 1-inch high drive coil.
它运用了两个15英寸低音和一个1英寸高音线圈驱动器。
Therefore the magnetic field analysis as for the drive coil is necessary.
因此,对于驱动线圈的磁场分析是必要的。
GMM is surrounded by the drive coil in the closed area of GMA, so it is difficult to realize temperature control.
超磁致伸缩执行器中超磁致伸缩材料处在驱动线圈围成的封闭型区域内,因而其温控较难实现。
