Abstract: In various embodiments, a speakerphone may comprise multiple (e.g., 16) microphones placed in a circular array around a central speaker. The microphones may be mounted vertically in the speakerphone with their respective diaphragms substantially parallel to the top surface of the speakerphone. The centrally mounted speaker may be coupled to a stiff internal speaker enclosure. The speaker enclosure may be made of a stiff, heavy material (e.g., a dense plastic) to prevent the speaker vibrations from excessively vibrating the speakerphone enclosure (which may affect the microphones). The speaker enclosure may also include a raised rim and ridges to increase its stiffness.
