    • A system for enhancing sound includes a support structure and one or more panels forming a panel structure. The panel structure defines a first and second portion of an oblong enclosure, both forming an approximated double ellipse profile, comprising a material having a sound reflective surface, and held by the support structure. The first portion extends between a first area proximate a first speaker driver and a second area proximate the listener. The second portion extends between a third area proximate a second speaker driver and a fourth area proximate the listener. The two portions are shaped such that sound waves emitted laterally from the first and second speaker drivers are reflected and focused toward the listener as spatially localized three-dimensional surround sound without electronically manipulating the sound signals and while reflectively reducing the effect of crosstalk.
    • 用于增强声音的系统包括支撑结构和形成面板结构的一个或多个面板。 面板结构限定了长方形外壳的第一和第二部分,两者都形成近似的双椭圆轮廓,包括具有声音反射表面的材料,并由支撑结构保持。 第一部分在靠近第一扬声器驱动器的第一区域和靠近收听者的第二区域之间延伸。 第二部分在靠近第二扬声器驱动器的第三区域和靠近收听者的第四区域之间延伸。 这两个部分被成形为使得从第一和第二扬声器驱动器横向发射的声波被反射并聚焦到收听者作为空间定位的立体环绕声,而无需电子地操纵声音信号,同时反射地减小串扰的影响。
