This paper reports on the results of our investigation into a loudspeaker system which provides a superior unidirectional radiation pattern in the speech frequency range. Our system is composed of the primary loudspeaker, the secondary loudspeaker, one sensing microphone, the unique sound reflector and the signal processor. The unidirectional radiation pattern is realized by composite sound of both loudspeakers.
