GEOPHONE WITH TUNABLE RESONANCE FREQUENCY

摘要

An illustrative geophone with tunable resonance frequency includes a first inductive assembly including an inductive coil having a first magnet arranged therein, wherein the first magnet and the first inductive coil move relative to each other, and a second inductive assembly including a second inductive coil having a second magnet arranged therein, wherein the second magnet and the second inductive coil move relative to each other. A coupling element couples a movable element of the first inductive assembly with a moveable element of the second inductive assembly. The first inductive assembly employs tunable damping to modify a resonant frequency of the second inductive assembly.

1. A geophone, comprising:
a first inductive assembly including a first inductive coil having a first magnet arranged therein, wherein the first magnet and the first inductive coil move relative to each other; a second inductive assembly including a second inductive coil having a second magnet arranged therein, wherein the second magnet and the second inductive coil move relative to each other; and a coupling element coupling a movable element of the first inductive assembly with a moveable element of the second inductive assembly, wherein the first inductive assembly employs tunable damping to modify a resonant frequency of the second inductive assembly.
