Abstract:
1. An apparatus, comprising: a first key configured to be manually actuatable by a user, the first key having a mechanism operative to mechanically generate vibrations in the first key that propagate outwardly from the first key along first, second, and third detection axes that are perpendicular to each other, in response to actuation of the first key; a key-actuation detection circuit coupled to the first key and configured to detect actuation of the first key, the key-actuation detection circuit including an inertial-sensor circuit configured to detect the vibrations propagating from the first key along the first, second, and third detection axes and to supply first, second, and third detection signals in response to the detection of the vibrations acting along the first, second, and third detection axes, respectively; a casing on which the first key is arranged; a board coupled to the casing and rigidly coupled to the inertial-sensor circuit in a manner that enables the inertial-sensor circuit to detect the vibrations that propagate through the casing from the first key along the first, second, and third detection axes in response to actuation of the first key; and a compliant-support device mounted between the casing and the board, the compliant support device configured to support the board in a resting position and to enable the board to move along the third detection axis with respect to the casing, wherein the first key includes a first mechanical-coupling element configured to exert a pressure on the board asymmetrically with respect to the second detection axis in response to actuation of the first key and cause the board to be inclined and rotate about the second detection axis.
