Disclosed is an active sound generation apparatus using a motor, the apparatus including a target sound generating signal generator configured to select the target sound and to generate a current command signal for driving the motor to generate the target sound, a current sensor configured to sense phase current of the motor, a motor controller configured to generate a voltage command for driving the motor to generate the target sound and to control driving of the motor based on a current command signal generated by the target sound generating signal generator, the phase current of the motor sensed by the current sensor, and a counter electromotive force compensation value of the motor, and a radiated noise generator configured to generate the target sound using vibration generated from the motor driven by the motor controller.
