多元件定向声阵列
摘要：
一种音频系统，包括左输入声道信号、右输入声道信号和分立中央输入声道。电路从该左输入声道信号和该右输入声道信号去除相关内容，并且在该中央输入声道信号中插入该相关内容以提供修改的左输入声道信号、修改的右输入声道信号和修改中央输入声道信号。由定向扬声器辐射该修改的左输入声道信号以使得在朝向收听区域方向中的辐射比在其他方向中的辐射更小。由定向扬声器辐射该修改的右声道输入声道信号以使得在朝向收听区域方向中的辐射比在其他方向中的辐射更小。
摘要（英）：

An audio system including a left input channel signal, a right input channel signal, and a discrete center input channel. Circuitry removes correlated content from the left input channel signal and the right input channel signal and inserts the correlated content into the center input channel signal to provide a modified left input channel signal, a modified right input channel signal, and a modified center input channel signal. The modified left input channel signal is radiated by a directional loudspeaker so that radiation in a direction toward a listening area is less than radiation in other directions. The modified right channel input channel signal is radiated by a directional loudspeaker so that radiation in a direction toward a listening area is less than radiation in other directions.
