摘要： A reflective loudspeaker array is cooperatively operable with an acoustically reflective planar surface to provide a constructive combination of direct and reflected sound waves that produces a uniform sound field. The uniform sound field provides a controlled sound field in the vertical and horizontal direction, and also provides uniformity from distances close to the reflective loudspeaker array to far way. The direct and reflected sound waves are advantageously and constructively combinable to generate a focused beamwidth of sound waves. The reflective loudspeaker array includes a plurality of loudspeakers coupled to a surface of the reflective loudspeaker array. The surface may be formed to include at least one curve with a radius of curvature. The reflective loudspeaker array may be placed adjacent an acoustically reflective planar surface such that a frontal plane of a loudspeaker adjacently located closest to the acoustically reflective planar surface is aligned perpendicularly, and a frontal plane of a loudspeaker spaced away from the acoustically reflective planar surface is not aligned perpendicularly.
摘要翻译：反射式扬声器阵列可与声学反射性平面表面合作地操作，以提供产生均匀声场的直接和反射声波的建设性组合。均匀的声场在垂直和水平方向上提供受控的声场，并且还提供距离反射式扬声器阵列很近的距离的一致性。直接和反射的声波有利地并且可建设性地组合以产生声波的聚焦波束宽度。反射式扬声器阵列包括耦合到反射式扬声器阵列的表面的多个扬声器。表面可以形成为包括至少一个曲率半径的曲线。反射式扬声器阵列可以放置在声学反射性平面表面附近，使得与声学反射性平面表面最接近的扬声器的正面平面垂直排列，并且与声学反射性平面表面隔开的扬声器的正面是不垂直对齐。
