Abstract:
1. A portable electronic device comprising: a first housing; a speaker coupled to the first housing; a first shaft coupled to the first housing, the first shaft capable of rotating about a first axis; a second housing; a microphone coupled to the second housing; a second shaft coupled to the second housing, the second shaft capable of rotating about a second axis, wherein the second axis is substantially parallel to the first axis; a link connecting the first shaft and the second shaft, wherein the link enables the first shaft and the second shaft to rotate in opposite directions; and a cam having a first slot and a second slot, wherein the first shaft is inserted through the first slot along the first axis, and the second shaft is inserted through the second slot along the second axis, the cam includes a first profile around a periphery of the first slot, the first profile including a peak and a valley and a second profile around a periphery of the second slot, the second profile including a peak and a valley, the first shaft includes a first tab offset from the first axis, the first tab movably coupled to the first profile so as to move the cam with respect to the peak and the valley of the first profile and the second shaft includes a second tab offset from the first axis, the second tab movably coupled to the second profile so as to move the cam with respect to the peak and the valley of the second profile, wherein the cam slides along the first shaft and the second shaft in response to rotation of the first shaft and the second shaft, wherein the first tab rests on the first peak, and a limit to which the first shaft can rotate is provided by the link, providing a stable angle when in a flip-open position.
