Abstract
A sound-activated wake-up device generates a wake-up signal for ending a sleep-mode in response to the sound of friction between an operating platform and an input device, or the sound of touching of the input device by the user. The wake-up device includes a sound detecting unit and a signal amplifying/comparing unit, and sound filtering structures and/or circuitry so as to prevent ambient sounds from activating the wake-up device.
