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.
Claims20
A method for generating sound with a motor, comprising:
- 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.
A system for generating sound, comprising:
- a motor having a rotor;
- a speaker;
- and
- one or more processors configured to:
- generate a motor-driving signal having an audio signal component;
- apply 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;
- apply a bandpass filter to the motor-driving signal to generate a filtered motor-driving signal;
- and
- apply the filtered motor-driving signal to the speaker to present audio content consistent with the sound generated by the motor.
A mobile platform, comprising:
- a motor controller configured to generate a motor-driving signal having an audio signal component;
- a speaker;
- and
- a motor being coupled to the motor controller, the motor having a rotor;
- wherein the motor controller is configured to:
- apply the motor-driving signal to the motor to generate a sound corresponding to the audio signal component;
- apply a bandpass filter to the motor-driving signal to generate a filtered motor-driving signal;
- and
- apply the filtered motor-driving signal to the speaker to present audio content consistent with the sound generated by the motor.
