Abstract
A speakerphone system is provide, comprising: at least one mechanical vibration sensor (MVS) adapted to convert mechanical vibrations in a speakerphone enclosure (enclosure) to a mechanical vibration error signal, and output the same as an MVS output signal; at least one microphone (mic) adapted to convert an input sound acoustic signal into an input sound electrical signal and to output the same as a mic output signal; and circuitry adapted to subtract the MVS output signal from the mic output signal and output the resultant signal as a speakerphone output signal.
