MULTIMICROPHONE CONFERENCE SYSTEM WITH AUTOMATIC MICROPHONE SELECTION

摘要

A modified speakerphone conference system with a plurality of microphones employs a comparator in combination with logic circuitry that selects the microphone with the greatest output and connects it to the speakerphone input while simultaneously disconnecting the others. In the absence of other inputs, a microphone that has control retains control despite pauses. Control can be seized, however, by any microphone with an overriding signal. Switching and the transmission of background noise are both minimized.
