FIELD: physics; geophysics.
SUBSTANCE: invention relates to geophysics and can be used in seismic exploration. The seismic vibrator has a rigid base with cavities on its surface, a tightening weight resting on the base and an induction-dynamic motor, the exciting coil of which is placed on the bottom surface of the tightening weight and rests on an armature plate, made of electroconductive material, mounted on the base. The armature plate has holes which link the cavities with the gap between the base and tightening weight, which reduces rarefaction of air in the gap between the armature and the exciting coil of the motor, and increases mechanical action of the base of the seismic vibrator on the ground.
EFFECT: high efficiency of the seismic vibrator.
