<p>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 (4,7) 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. </p> |
