ABSTRACT:
For use in geophones to support either the coil or the permanent magnet, a spring formed from a disc, said spring having an outer ring, an inner ring, and three legs connecting the outer and inner rings. The legs are equidistant from one another and substantially equal in length. The inner edge of each leg lies on an arc having a radius at least 1.25 times greater than the distance from the center of the spring to the inner edge of the leg at the point where the leg joins the inner ring. For each leg, the straight-line distance between the points where a leg joins the inner and outer rings is equal to or greater than the distance from the center of the spring to an outer edge of the outer ring.
