Claim:
1. A digital pen apparatus that captures pen strokes and audio, the digital pen apparatus comprising: a substantially cylindrical body; and components disposed in the substantially cylindrical body, wherein the components include a microphone, wherein the components are arranged and fixed within the substantially cylindrical body such that a weight distribution associated with the components causes the substantially cylindrical body to orient the microphone for reception of ambient sound when the substantially cylindrical body is placed on a supporting surface, wherein the weight distribution associated with the components is configured to cause the substantially cylindrical body to roll to an orientation of the microphone for reception of the ambient sound when the substantially cylindrical body is placed on the supporting surface with the microphone in a different orientation, wherein the ambient sound is received by the microphone primarily via the supporting surface rather than via air coupling when the substantially cylindrical body is placed on the supporting surface, and the weight distribution associated with the components orients the microphone toward and in contact with the supporting surface, wherein the weight distribution associated with the components is configured to position a center of gravity of the components below a central axis of the substantially cylindrical body when the substantially cylindrical body is placed on the supporting surface, wherein the microphone and the center of gravity are positioned on a same side below the central axis such that the microphone is oriented downward toward and in contact with the supporting surface, when the substantially cylindrical body is placed on top of the supporting surface, for reception of the ambient sound via the supporting surface rather than via the air coupling, wherein the components further include a heat sink and a counterbalance element, wherein the heat sink is positioned on a same side as the center of gravity, and wherein positioning the center of gravity below the central axis is independent of the counterbalance element.
