1. A head-mountable device comprising:
a frame supporting an optical module;
a temple component supporting a first electronic component;
an earpiece supporting a second electronic component; and
a hinge configured to allow the earpiece to rotate relative to the temple component and about an axis of rotation, the hinge comprising:
a cam comprising a ramp;
a follower; and
a spring element biasing the follower against the ramp of the cam;
a wire operatively connecting the first electronic component to the second electronic component and extending through the cam, the follower, and the spring element,
wherein the hinge is configured to allow the earpiece to rotate relative to the temple component and between:
a stowed position with the earpiece collapsed toward the frame;
an open position with the earpiece extended away from the frame; and
a head retention position with the earpiece biased away from the frame and beyond the open position, wherein the hinge is biased to require a first maximum torque when transitioning from the stowed position to the open position and a second maximum torque when transitioning from the open position to the head retention position, the first maximum torque being greater than the second maximum torque.
