Abstract: In an embodiment an apparatus includes a graphical display panel and a loudspeaker. The panel has a display layer for displaying images and defines a plurality of apertures penetrating through at least the display layer. The loudspeaker includes a diaphragm arranged substantially parallel to the display layer. Sound from the loudspeaker diaphragm is directed outside a host device through the apertures. The speaker may be an electret or a piezo-electric speaker for thinness. There may be apertures on an opposed side of the host device housing to achieve a dipole pattern which is directed and gives acoustic privacy to the user, or a rear acoustic cavity for a monopole pattern which more broadly disperses the sound. One illustrated embodiment is selectable between monopole and dipole. Size and total area of the holes determines acoustic resistance and so a method is described to determine those from physical parameters of the display panel.

Abstract translation: 在一个实施例中，装置包括图形显示面板和扬声器。 面板具有用于显示图像的显示层，并且限定穿透至少显示层的多个孔。 扬声器包括基本上平行于显示层布置的隔膜。 来自扬声器隔膜的声音通过孔径被引导到主机设备外部。 扬声器可以是驻极体或用于薄的压电扬声器。 在主机设备壳体的相对侧上可以存在孔，以实现对用户定向并给予声学隐私的偶极图案，或者更广泛地分散声音的单极图案的后声腔。 一个所示实施例可在单极和偶极之间选择。 孔的尺寸和总面积决定了声阻，因此描述了从显示面板的物理参数确定的方法。
