US Patent 10051354 Apparatus for comprehensive perception of sound

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.
