Apparatus and methods for reducing noise audible from a speaker

摘要

A method and apparatus for reducing speaker noise involves producing a control signal indicating whether or not audio program content is imminent in an audio signal operable to be transmitted to a speaker and transmitting the control signal for use by a speaker controller. The speaker controller receives the control signal and the audio signal or a speaker drive signal and provides the speaker drive signal to the speaker in response to the control signal indicating that audio program content is imminent and ceases to provide the speaker drive signal in response to the control signal indicating that audio program content is not imminent.
