    Abstract: A portable computing device having a substantially non-conducting outer housing and alternative electrical grounding and audio system architectures is disclosed. The device can be a laptop computer having a main logic board, a keyboard assembly, an audio source positioned below the keyboard assembly, and an equalizer electrically coupled to the audio source, with each of these components being electrically coupled to a universal grounding structure. The audio source emits sound waves that are propagated through the keyboard assembly and between gaps between keyboard keys and the outer housing. Settings for the equalizer can be selected to account for sound absorption and amplification characteristics of the sound waves along these sound transmission paths. The universal grounding structure includes a plurality of separate ground components that are electrically intercoupled, each being substantially smaller than the overall portable computing device, and also includes an electromagnetic interference shield around the main logic board.

    Abstract translation: 公开了一种具有基本不导电的外壳和替代的电接地和音频系统结构的便携式计算设备。 该装置可以是具有主逻辑板，键盘组件，位于键盘组件下方的音频源以及电耦合到音频源的均衡器的笔记本电脑，其中每个部件电耦合到通用接地结构。 音频源发出通过键盘组件传播的声波，以及键盘键和外壳之间的间隙。 可以选择均衡器的设置以考虑沿着这些声音传播路径的声波的吸声和放大特性。 通用接地结构包括电互相耦合的多个单独的接地部件，每个独立的接地部件均小于整个便携式计算设备，并且还包括围绕主逻辑板的电磁干扰屏蔽。
