A waveguide is provided in communication with the at least one auxiliary motor and in sonic resonance with sound produced by the auxiliary motor to amplify and/or to modify the audible sound. ## Claims ### Claim 1 A system for a vehicle, comprising: at least one auxiliary motor configured to mechanically operate a vehicle component based on receiving a motion control signal; wherein the at least one auxiliary motor is configured to produce an audible sound based on receiving an auditory control signal, and wherein the audible sound generated is a noise-cancelling sound. ### Claim 2 (depends on 1) The system of claim 1, further comprising a waveguide in communication with the at least one auxiliary motor to amplify and direct the audible sound. ### Claim 3 (depends on 2) The system of claim 2, wherein the waveguide is part of an electromagnetic shielding for the at least one auxiliary motor or related circuitry. ### Claim 4 (depends on 2) The system of claim 2, wherein the waveguide is configured to resonate a sound produced by the at least one auxiliary motor to amplify the audible sound. ### Claim 5 (depends on 1) The system of claim 1, wherein the noise-cancelling sound is for canceling out or reduce a sound perceivable at or around the vehicle. ### Claim 6 (depends on 5) The system of claim 5, wherein a sensor is provided to detect the sound perceivable at or around the vehicle. ### Claim 7 (depends on 1) The system of claim 1, further comprising a controller configured to output the auditory control signal and the motion control signal. ### Claim 8 (depends on 7) The system of claim 7, wherein the controller is configured to output the auditory control signal to cause the at least one auxiliary motor to produce the audible sound to cancel a noise produced by the at least one auxiliary motor. ### Claim 9 (depends on 7) The system of claim 7, wherein the controller is further configured to detect the sound perceived at or around the vehicle. ### Claim 10 (depends on 9) The system of claim 9, further comprising a microphone to detect the sound. ### Claim 11 (depends on 1) The system of claim 1, wherein the at least one auxiliary motor includes at least one motor selected from a group comprising: a seat motor, a sunroof motor, a door latch motor, a liftgate motor, a power-operated swing door actuator motor, and a window regulator motor. ### Claim 12 (depends on 5) The system of claim 5, further comprising a controller configured to detect a noise signal of the sound and generate a noise compensation signal for transmission to the at least one auxiliary motor to produce the audible sound. ### Claim 13 (depends on 12) The system of claim 12, wherein the produced audible sound is out of phase with the sound to destructively interfere with the sound. ### Claim 14 (depends on 5) The system of claim 5, further comprising a controller configured to output the auditory control signal while outputting the motion control signal, wherein the noise generated by the vehicle component is cancelled when the controller is outputting the auditory control signal. ### Claim 15 A system for a vehicle, comprising: at least one auxiliary motor configured to mechanically operate a vehicle component based on a motion control signal and to produce an audible sound; and a controller configured to output at least one of the motion control signal and an auditory control signal to actuate the at least one auxiliary motor to produce the audible sound to cancel noise generated by the actuation of the at least one auxiliary motor. ### Claim 16 (depends on 15) The system of claim 15, further comprising a sensor for sensing a noise signal for cancellation by the audible sound. ### Claim 17 A method of generating an audible sound in proximity to a motor vehicle, comprising: sensing a sound signal; transmitting an auditory control signal to an auxiliary motor of a vehicle component mounted to the motor vehicle; and producing the audible sound by the auxiliary motor in response to receiving the auditory control signal, wherein the audible sound is a noise cancelling sound. ### Claim 18 (depends on 17) The method of claim 17, wherein the noise cancelling sound is generated by the auxiliary motor to destructively interfere with the sound signal. ### Claim 19 (depends on 17) The method of claim 17, wherein the noise cancelling sound is out of phase with the sound signal. ### Claim 20 (depends on 17) The method of claim 17, further comprising: transmitting a motion control signal to the auxiliary motor of the vehicle component during transmitting the auditory control signal; and mechanically actuating the vehicle component by the auxiliary motor in response to the motion control signal, wherein a sound generated during mechanically actuating the vehicle component by the auxiliary motor in response to receiving the motion control signal is eliminated or reduced by the audible sound produced by the auxiliary motor in response to receiving the auditory control signal.
