Abstract
A method for generating sound with a motor, including: generating a motor-driving signal having an audio signal component; applying the motor-driving signal to the motor, wherein the motor-driving signal drives the motor to generate a sound corresponding to the audio signal component; applying a bandpass filter to the motor-driving signal to generate a filtered motor-driving signal; and applying the filtered motor-driving signal to a speaker to present audio content consistent with the sound generated by the motor.
