Today the most commonly used geophone is the magnet-electrical velocity geophone, also called the moving-coil geophone, moving-coil geophone is one of important link in the seismic exploration.

目前最常用的地震检波器是磁电式速度型地震检波器，又称动圈式检波器，动圈式检波器的测试是地震勘探中一个重要的环节。

It was devoted to the relative damping measurement for overdamped geophone with a moving coil of constant velocity.

对动圈式恒速度型过阻尼地震检波器相对阻尼系数的测量方法进行了研究。
