First Claim
Patent Images
1. An apparatus, comprising:
- a first microphone array in a first horizontal plane comprising more than two microphones equally spaced around a perimeter of a base of the apparatus;
a curved neck that includes a bottom portion that is coupled to the base and off a center from the base and a top portion that is coupled to a head, wherein the curved neck extends and curves upward from the base toward a centerline extending perpendicularly from the center of the base; and
a second microphone array in a second horizontal plane that is part of the head, wherein the first horizontal plane is different from the second horizontal plane; and
a camera included in the head that is pointed upwards and captures images reflected off from a reflective surface on the head and the reflective surface on the head is located above the camera.

Abstract
A camera speakerphone having a microphone array may be used for videoconferencing. Example microphone array designs described herein may be used to perform Sound Source Localization (SSL) and improve audio quality of captured audio. In one example, an omni-directional camera speakerphone includes a base having a speaker and at least one microphone. A neck is coupled to the base which is coupled to a head. The head includes an omni-directional camera and at least one microphone.
