Abstract
The present disclosure relates to a transducer assembly including a transducer having a movable member, and a servo-loop controller configured to compensate for effects of a disturbance on the transducer assembly by adjusting a bias voltage applied to the transducer. A servo-loop controller having a smaller bandwidth for out-of-band disturbances than for in-band disturbances and configured to control the bias voltage based on a feedback signal generated by a sensor that detects an effect of the disturbance on the transducer assembly. The transducer assembly can be implemented as a microphone or a speaker among other sensors and actuators.
