Disclosed is a pattern coil type vertical vibrator including: a housing; a magnetic circuit unit placed in the internal space of the housing, and including a magnet perpendicularly placed and a yoke for fixedly receiving the magnet therein; spring members provided with upper ends fixed to the housing and lower ends fixed to the magnetic circuit unit for vertically and elastically supporting the magnetic circuit unit; a vibrating unit, including a weight assembled with the yoke of the magnetic circuit unit, vertically vibrated together with the magnetic circuit unit through the spring members; and a pattern coil, printed on an upper surface of a base for closing a lower surface of the housing, to which power is supplied, so that the pattern coil is interlinked with a magnetic field generated from the magnet and generates force just upwardly when the power is supplied to the pattern coil.
