Abstract: A technique for joint production of vibration and sound is provided. According to an example embodiment, the technique is provided by an apparatus including a unit for jointly producing vibration and sound to reproduce an input audio signal provided as input thereto, the unit 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 the sound through the at least one outer surface of the padding and a unit for regulating perceivable intensity of vibration in dependence of at least one characteristic of the input audio signal.

Abstract: The invention relates to a seat arranged for enhanced sound perception via vibration including a padding and a sound reproduction assembly (20), which includes at least one vibration source (26), at least one elastic element (16, 21) and at least one frame structure (18, 22), which sound reproduction assembly is at least partially arranged inside the padding. The elastic element/-s (16, 21) are nonhomogenous element/-s and located in contact with the frame structure (18, 22) and the vibration source (26) and configured to provide elastically and mechanically tuned mounting and that the elastic element/-s are configured to create at least lateral vibration to the surface of the seat.

Abstract: An apparatus for comprehensive perception of sound, preferably a cushion, where vibration and sound is produced with a mechanical device wrapped inside a padding, wherein (a) the device radiates sound by generating mechanical vibration directly to the padding that can be felt and listened on the outer surface of the padding, (b) the device radiates airborne sound through the padding, (c) in order to avoid acoustical and mechanical resonances, the padding includes an acoustically denser and lossy layer and a layer that is acoustically less dense and porous, and (d) the device includes at least one board, and the vibration of the boards is generated using at least one vibrating mechanical actuator.
