A voice-controlled electronic device that includes an axisymmetric device housing having a longitudinal axis bisecting opposing top and bottom surfaces and a side surface extending between the top and bottom surfaces. The device can further include a plurality of microphones disposed within the device housing and distributed radially around the longitudinal axis; a processor configured to execute computer instructions stored in a computer-readable memory for interacting with a user and processing voice commands received by the plurality of microphones and first and second transducers configured to generate sound waves within different frequency ranges.

Input devices having a thin profile and good comfort and feel are disclosed. In embodiments, an input device includes a sensor layer configured to effectuate a key press upon application of an activation force, and a collapsible layer coupled to the sensor layer. The collapsible layer may be configured to collapse in response to a collapsing force that is substantially equal to the activation force. When the collapsible layer collapses, the sensor layer may simultaneously effectuate the key press in response to application of the collapsing force.

It is provided a multi-purpose analogue device (1) for tracing curves and geometric transformations comprising a first guide (3) defining a first translation axis (3a) and movable on a tracing plane along a predetermined direction perpendicular to the first axis (3a), a second guide (4) integral to the first guide (3) defining a second translation axis (4a) perpendicular to the first axis (3a), a connector (5) configured to be connected to the guides (3, 4) and comprising a third guide (50) defining a third translation axis (5a), constrained in a compliant way and roto-translatable with respect to the second guide (4), a first slider (6) constrained in a compliant way to the first guide (3), movable along the first axis (3a) and including first movement means (60) configured to allow movement of the first slider (6) in the plane along a movement direction (6a), and support means (61) configured to track a mark on the plane or to support in contact with the plane tracking means, wherein the connector (5) further comprises a fourth guide (51) defining a fourth translation axis (5b) and integrally constrained or integral, to the third guide (50) such that the translation axes (5a, 5b) are mutually perpendicular so as to allow for at least a first and second configuration in which the first slider (6) is also constrained in a compliant way respectively to the third guide (50) and translatable along the third axis (5a) or also to the fourth guide (51) and translatable along the fourth axis (5b).
