    • An audio device incorporates a plurality of acoustic drivers and employs them to form either a first acoustic interference array generating destructive interference in a first direction from the plurality of acoustic drivers or a second acoustic interference array generating destructive interference in a second direction from the plurality of acoustic drivers in response to the orientation of the casing of the audio device relative to the direction of the force of gravity. An audio device incorporates a first acoustic driver having a first direction of maximum acoustic radiation and a second acoustic driver having a second direction of maximum acoustic radiation, where the first and second directions of maximum acoustic radiation are not in parallel, and where the audio device employs the first acoustic driver or the second acoustic driver in acoustically outputting a sound of a predetermined range of frequencies in response to the orientation of the casing of the audio device relative to the direction of the force of gravity. An audio device incorporates first acoustic driver at least partially overlain by a first acoustic reflector to define a first effective direction of maximum acoustic radiation and a second acoustic driver at least partially overlain by a second acoustic reflector to define a second effective direction of maximum acoustic radiation, wherein when the audio device is positioned in a room such that the direction of maximum acoustic radiation of the first acoustic driver is substantially perpendicular to the direction of the force of gravity, the first effective direction of maximum acoustic radiation is bent more towards a listening position at which a listener is expected to be located than the first direction of maximum acoustic radiation and away from a floor, and the second effective direction of maximum acoustic radiation is bent more towards the listening position than the second direction of maximum acoustic radiation and away from a wall.
    • 音频装置包含多个声学驱动器并且使用它们来形成从多个声学驱动器产生在第一方向上的相消干涉的第一声学干涉阵列或从多个声学驱动器产生在第二方向上产生相消干涉的第二声学干涉阵列 响应于音频设备的壳体相对于重力方向的取向的声学驱动器。 音频装置包括具有最大声辐射的第一方向的第一声学驱动器和具有最大声辐射的第二方向的第二声学驱动器,其中最大声辐射的第一和第二方向不是平行的,并且其中音频装置 响应于音频设备的壳体相对于重力方向的取向,使用第一声学驱动器或第二声学驱动器以声学方式输出预定频率范围的声音。 音频装置包括至少部分地由第一声反射器覆盖以限定最大声辐射的第一有效方向的第一声驱动器,以及由第二声反射器至少部分地覆盖以限定最大声辐射的第二有效方向的第二声驱动器 ,其中当所述音频设备定位在房间中使得所述第一声学驱动器的最大声辐射的方向基本上垂直于所述重力方向时,所述最大声辐射的所述第一有效方向更倾向于倾听 预期听众所在的位置比最大声辐射的第一方向远离地面,并且最大声辐射的第二有效方向比最大声辐射的第二方向更倾向于向收听位置弯曲 从墙上。
