1. A vehicle comprising:
- a micro-electromechanical sensor attached to a door and in communication with a processor; and
a speaker in communication with the processor;
whereinoperation of the door toward a closed position is measured by the micro-electromechanical sensor to define a corresponding door acceleration, the processor determines a corresponding door-operating event based on the corresponding door acceleration and the speaker delivers a corresponding audio signal in response to the corresponding door-operating event, wherein the audio is a noise-canceling signal that is inversely defined by a door noise signature of the corresponding door-operating event, wherein the noise-canceling signal is defined by the processor after the corresponding door-operating event is determined;
wherein the corresponding door-operating event is a closure of the door.

Abstract
A vehicle includes a three-axis accelerometer attached to a door and in communication with a processor. A speaker is in communication with the processor. Operation of the door toward a closed position is measured by the accelerometer to define a corresponding door acceleration. The processor determines a corresponding door-operating event based on the corresponding door acceleration and the speaker delivers a corresponding audio signal in response to the corresponding door-operating event.

8. A method for operating a speaker for a vehicle, the method comprising steps of:
-
positioning a micro-electromechanical sensor on a portion of a door of the vehicle, wherein the micro-electromechanical sensor is a three-axis accelerometer; operating the door from an open position toward a closed position; measuring a rotational movement of the door, wherein the micro-electromechanical sensor measures the rotational movement; communicating the rotational movement of the door to a processor; determining a corresponding door-operating event, wherein the processor uses the rotational movement of the door to determine at least one of a door position, a rotational speed of the door, a vertical deflection of the door and a target resonance of the door; determining a corresponding audio response, wherein the processor evaluates the door-operating event and communicates the corresponding audio response to the speaker disposed within the door; and delivering the corresponding audio response, wherein the speaker emits a corresponding audio signal that is indicative of the corresponding audio response, wherein the processor is operable to define a maintenance state, wherein during the maintenance state, the corresponding door-operating event is defined by the vertical deflection of the door moving into the closed position, wherein the corresponding audio signal during the maintenance state is defined by the vertical deflection of the door in relation to a baseline vertical deflection. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method for operating a speaker for a vehicle, the method comprising steps of positioning a micro-electromechanical sensor on a vehicle door;
measuring a door acceleration as the vehicle door moves into a closed position; communicating the door acceleration of the vehicle door to a processor; determining a corresponding door-operating event based upon the door acceleration; determining a corresponding audio response based upon the door-operating event; and delivering the corresponding audio response to the speaker, wherein the speaker emits an audio signal indicative of the corresponding audio response, wherein the corresponding audio signal is a noise-canceling signal that is inversely defined by a door noise signature of the corresponding door-operating event, wherein the noise-cancelling signal is defined after the corresponding door-operating event is determined, wherein the corresponding door-operating event is a closure of the vehicle door. - View Dependent Claims (17, 18, 19)
