Claim 14:
15. A computer readable storage medium having a motor signal compensation program stored thereon, the motor signal compensation program being executable by at least one processor to perform a method for compensating a signal of a motor, the method comprising:
acquiring an original signal and nonlinear parameters of the motor;
calculating a compensation signal for the original signal according to the acquired nonlinear parameters; and
loading the calculated compensation signal into the motor to excite the motor to vibrate wherein
the nonlinear parameters comprise an electromagnetic force coefficient b, a spring stiffness coefficient k and a damping Rm, and the functions of the nonlinear parameters with respect to a vibrator displacement x are expressed as follows:

b(x)=b0+b1x+b2x2+ . . . +bnxn 

k(x)=k0+k1x+k2x2+ . . . +knxn 

Rm(x)=R0+R1x+R2x2+ . . . +Rnxn 

where n is an arbitrary positive integer, and b0˜bn and k0˜kn, R0˜Rn are nonlinear parameter coefficients.
