Abstract
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.
