1. A computer-implemented method comprising:
detecting, by one or more computer processors, a contextual need for sound generation on a rollable display device, wherein the rollable display device comprises an array of micro-speakers mounted on one or more microfluidics panels and a plurality of embedded piezoelectric strips;
identifying, by one or more computer processors, one or more environmental parameters associated with an environment surrounding the rollable display device;
determining, by one or more computer processors, a rolling profile associated with the rollable based on the detected contextual need and the one or more identified environmental parameters, further comprising:
deriving, by one or more computer processors, the rolling profile to mimic acoustic properties associated with one or more nearest neighbors utilizing a K nearest neighbor (kNN) classification analysis based upon one or more historical audio emitting devices;
initiating, by one or more computer processors, a roll of the rollable display device by applying an electric field based on the determined rolling profile to the plurality of embedded piezoelectric strips within the rollable display device; and
adjusting, by one or more computer processors, an output direction of each micro-speaker in the array of micro-speakers utilizing the respective microfluidics panel.
