摘要： A method for substantially eliminating the effect of mechanical vibration on an audio input to a speakerphone system is provided herein, the method comprising: receiving mechanical vibrations and an input sound acoustic signal at a microphone (mic); converting the received mechanical vibrations and input sound acoustic signal into an input sound electrical signal, and outputting the same as a mic output signal; receiving mechanical vibrations at a mechanical vibration sensor (MVS); converting the received mechanical vibrations into a mechanical vibration error signal, and outputting the same as an MVS output signal; and generating a speakerphone system output signal by subtracting the MVS output signal from the mic output signal.

摘要： An audio/video receiver configured to limit the power delivered to its speakers based on real time calculations. First, power delivered to the speakers is limited to the power rating of the speakers during short durations. Second, a secondary longer time constant Root-Mean-Square (RMS) detector limits sustained power to the speakers for a predetermined fraction of the peak power rating.
