    摘要： The invention provides a speakerphone having a low-profile housing having an upward-oriented speaker on an upper surface of the housing and a downward-oriented microphone on a lower surface of the housing. The lower surface of the housing is domed, for example, a parabolic dome, enabling a low opening distance between the housing and a support surface on which the speakerphone rests, in turn, enabling a low housing profile. The speaker is retained by an elastic rubber cup member.

    摘要翻译： 本发明提供了一种扬声器电话，其具有在壳体的上表面上具有向上定向的扬声器的低轮廓壳体，以及在壳体的下表面上的向下定向的麦克风。 外壳的下表面是圆顶形的，例如抛物面的圆顶，使得壳体与扬声器电话所在的支撑表面之间的较小的开口距离进而能够实现低的外壳轮廓。 扬声器由弹性橡胶杯构件保持。
