    • 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.
    • 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。

    • Sound processing systems have been developed that create a surround effect without quality degradation experienced by known sound processing systems in non-optimum listening environments. The sound processing systems may include matrix decoding systems that manipulate input signals prior to converting them into a number of output signals so that the output signals are a function of a greater number of input signals. These sound processing systems may also or alternately include a bass management system that from the input signals preserves the low frequency components of the input signals in separate channels. Both the matrix decoding systems and bass management systems may also produce additional signals. Further, the matrix decoding and bass management systems may be implemented separately or jointly in vehicular sound systems.
    • 已经开发了声音处理系统,其创建环绕效果,而不会在非最佳聆听环境中由已知声音处理系统所经历的质量降级。 声音处理系统可以包括在将它们转换成多个输出信号之前操纵输入信号的矩阵解码系统,使得输出信号是更多数量的输入信号的函数。 这些声音处理系统还可以或者可选地包括低音管理系统,其从输入信号中将输入信号的低频分量保持在单独的声道中。 矩阵解码系统和低音管理系统都可以产生附加信号。 此外,矩阵解码和低音管理系统可以在车载声音系统中单独地或共同地实现。
