The invention discloses an omnidirectional vector electrostatic levitation geophone, comprising: a regular tetrahedron hollowed-out structure, and an inner hollowed-out base and an outer hollowed-out base that are provided inside and outside the regular tetrahedron hollowed-out structure and at equal distance from the regular tetrahedron hollowed-out structure, and have the same structure as and different size from the regular tetrahedron hollowed-out structure; the regular tetrahedron hollowed-out structure has a solid part and a hollowed-out part of each surface thereof, the solid part is a quadrangle divided from angular bisectors of two angles on each surface and an isosceles triangle that abuts the solid part by a surface central point, and the hollowed-out part is two triangles that are divided from the angular bisectors of the two angles and abut each other by a surface center. In the invention, a spatial full-vector detection structure is designed, a completely new omnidirectional vector geophone technology is realized, thereby completing detection of full information including frequency, amplitude, phase, vibration direction of the seismic wave field, especially divergence and curl of a wave force field.
