title: Note: Improving the performance of a geophone through suspension system configuration.
abstract: A suspension system of classical geophone was developed, adopting multiple pairs of leaf springs as a substitute for one pair. The finite element analysis was used as the solving means, and the results indicated that the geophone performance with developed suspension system was more favorable than that with conventional suspension system. First, the operating broadband of the improved geophone was wider than that of the conventional geophone. Second, the distortion of output signal for a geophone was slightly reduced, which was usually enlarged with improving the ratio of spurious resonant frequency to natural frequency.
