摘要： 57 A spring for use in geophones to suspend coils within a magnetic field assembly. The spring is formed from a disc and comprises an outer ring, an inner ring and three legs connecting the outer and inner rings, which legs are formed by removing portions of the disc in a predetermined pattern. The inner edge of each leg (7) lies on an arc having a radius at least 1.25 times greater than the distance from the center (9) of the spring (4) to the inner edge of the leg (7) at the point (11) where the leg joins the inner ring (6).
Preferably each leg (7) is wider at its ends (10, 11) than it is in its middle (12).摘要翻译： 用于地震检波器的弹簧，用于在磁场组件内悬挂线圈。 弹簧由圆盘形成，包括外圈，内圈和连接外圈和内圈的三条腿，通过以预定图案去除盘的部分而形成这些腿。 每个支腿（7）的内边缘位于圆弧上，该圆弧的半径至少比从弹簧（4）的中心（9）到支腿（7）的内边缘 11）其中腿连接内环（6）。 优选地，每个腿（7）在其端部（10,11）处比在其中间（12）处更宽。

摘要： A geophone spring system for suspending a reference mass which comprises first means (2,3,5) for centering the reference mass both laterally and along its axis and second means (4,7i for centering the reference mass laterally and for providing a heavily damped compliance in a radial direction to prevent the first means (2,3,5) from being stressed beyond its elastic limits.
