VIBRATION MOTOR AND PORTABLE TERMINAL DEVICE USING SAME

WIPO Patent Application WO/2010/026709

A1

A vibration motor (100) is provided with: a multilayer substrate (10) having a first planar coil (12a) and a second planar coil (12b) arranged with a space therebetween; a permanent magnet (20), which has a magnetic pole surface facing the planar coils and is arranged movably on the planar coils in the planar coil arrangement direction; and a movement control section (not shown in the figure) which reciprocates the permanent magnet (20); and plate springs which are arranged on the both end sections of the planar coil arrangement and urge the permanent magnet (20) in the moving direction when the permanent magnet (20) is reciprocated.  The movement control section controls to generate a thrust force due to an attracting force and a repulsive force between the permanent magnet (20) and the planar coil, by making a current flow in the planar coils, and the permanent magnet (20) is reciprocated in a state where the permanent magnet is tilted from an upper surface (10a) of the multilayer substrate (10).
