Abstract:
According to an example embodiment, an apparatus for active cancellation of sound and vibration is provided, the apparatus including sound and vibration generation components for jointly producing vibration and sound under control of a driving signal provided as input thereto, the components being arranged inside a padding to generate mechanical vibration that is perceivable as a vibration and sound on at least one outer surface of the padding and to radiate a sound through the at least one outer surface of the padding, a feedback unit for providing feedback information that is indicative of acoustic energy of sound and vibration inside the padding, and a drivert for generating the driving signal in dependence of the feedback information so as to reduce energy of ambient sound and vibration induced inside the padding due to one or more external sources of sound and vibration.
