Patent ID: 7606376

Claim:
An automotive audio controller for receiving an audio signal from an audio source and providing a filtered audio signal, the audio controller comprising: a non-sonic excitement sensor attached to a surface on or within an automobile, the non-sonic excitement sensor configured to detect a non-sonically induced excitement level of the surface; a power estimator coupled to the non-sonic excitement sensor, where the power estimator is configured to receive the detected non-sonically induced excitement level, the power estimator further configured to convert the detected non-sonically induced excitement level into a vibration power value that is indicative of the non-sonically induced excitement level detected by the non-sonic excitement sensor; and a dynamic filter coupled to the power estimator, where the dynamic filter is configured to receive the vibration power value, and the dynamic filter is further coupled to the audio source, where the dynamic filter is further configured to receive the audio signal; and where the dynamic filter is configured to generate a filtered audio signal based on the audio signal and the vibration power value, and the filtered audio signal is amplified to generate a driving electrical signal for a speaker.
