  • Teleconferencing device having acoustic transducers positioned to improve acoustic echo return loss
    Patent number: 6275580
    Abstract: A teleconferencing terminal for hands-free full duplex audio telecommunication systems is provided which limits the amount of acoustic coupling between the terminal's microphone and loudspeaker. A directional microphone is positioned equidistantly from two loudspeakers such that audio signals emanating from the loudspeakers are acoustically coupled by the microphone at substantially equivalent audio levels. The terminal loudspeakers are impedance matched and connected in phase opposition with respect to each other so that signals emanating from the loudspeakers in the vicinity of the microphone are destructively canceled.
