<p>An apparatus e.g. a mobile phone (10) with a first axis of rotation (90), includes a surface (70) , upon which the apparatus may be supported, and a motor (200). The motor has a rotor shaft with a second axis of rotation. The motor is activated to alert a user of the apparatus to an event. The motor is positioned within the apparatus such that the second axis of rotation is substantially parallel to the first axis of rotation (90), and activation of the motor produces a turning moment, causing the apparatus to rotate about the first axis (90).</p> |
