FIELD: physics.
SUBSTANCE: exemplary geophone with a tuned resonant frequency comprises the first inductive assembly including an inductor with the first magnet mounted therein, wherein the first magnet and the first inductor are movable relative to each other, and the second inductive assembly including the second inductor with the second magnet installed therein. The second magnet and the second inductor are movable relative to each other. The communication element connects the movable element of the first inductive assembly with the movable element of the second inductive assembly. The first inductive assembly uses adjustable damping to change the resonant frequency of the second inductive assembly.
EFFECT: high accuracy of the obtained data.
