ABSTRACT:
In various embodiments, a speakerphone may comprise multiple (e.g., 16) microphones placed in a circular array around a central speaker. Each microphone may be mounted to the speakerphone through a microphone support. The microphone support may be made of a flexible material and have various features designed to minimize interference to the microphone (e.g., from the speaker and/or vibrations external to 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).
