The present invention relates to a haptic actuator. A vibrator comprises a first magnet and a second magnet which are disposed so as to be spaced apart from each other at one end of the longitudinal direction of a coil member; a third magnet and a fourth magnet which are disposed so as to be spaced apart from each other at the other end of the longitudinal direction of the coil member; a first magnetic body mounted on one end of the transverse direction of the first magnet and the third magnet; a second magnetic body mounted on the other end of the transverse direction of the second magnet and the fourth magnet; and a first weight and a second weight which are mounted respectively on the first magnetic body and the second magnetic body, wherein N pole is formed in a direction at which the polarities of the first magnet and the second magnet face each other and S pole is formed in a direction opposite to said direction, N pole is formed in a direction at which the polarities of the third magnet and the fourth magnet face each other and S pole is formed in a direction opposite to said direction, and the lines of magnetic force diverging from the N poles of the first magnet, the second magnet, the third magnet and the fourth magnet converge on the coil member. |
