The MF voice coil is of copper-coated aluminium ribbon, expensively edge-wound over a polyimide former to increase sensitivity by maximising the amount of copper in the magnet gap.
中频音圈为镀铜铝带，在其聚酰亚胺成形品上有昂贵的饰边，尽可能加大铜在磁隙中的量来增加灵敏度。

This competition leads to high angular sensitivity in response to the refractive index variation of the sample solution in the gap.
由于该竞争行为，当两单栅间隙内充盈的样品溶液折射率发生变化时，体现为反射谱上较高的角度灵敏度。

Small contact gap, snap action, high sensitivity and small operating travel.
