A speaker assembly includes a wedge-shaped acoustic waveguide and an audio driver. The wedge-shaped acoustic waveguide includes: a first face including a slot opening formed therein; a second surface joined to the first surface at an edge, the second surface being inclined at a first angle with respect to the first surface; and a surface disposed opposite the edge and connected between the first face and the second face. The audio driver is coupled to the second face such that the audio driver is inclined at a first angle relative to the first face. The first face is oriented to face a first direction and the audio driver is oriented to face a second direction. A pressure level of acoustic energy emitted by the audio driver is greater in the second direction than in the first direction. A vehicle includes a passenger compartment, a strut extending upwardly at a first angle relative to the passenger compartment, and a speaker assembly mounted on the strut.
一种扬声器组件,包括楔形声波导和音频驱动器。楔形声波导包括:第一面,包括在其中形成的缝隙开口;第二面,在边缘处与第一面接合,第二面相对于第一面倾斜第一角度;以及表面,设置为与该边缘相对并且连接在第一面和第二面之间。音频驱动器耦合到第二面,使得音频驱动器相对于第一面倾斜第一角度。第一面被定向为面向第一方向,并且音频驱动器被定向为面向第二方向。音频驱动器发出的声能的压级沿第二方向比沿第一方向要大。车辆包括:乘客舱、相对于乘客舱以第一角度向上延伸的支柱、以及安装在支柱上的扬声器组件。
