Patent ID: 11871194
Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 12:
13. A computer system comprising:
one or more computer processors;
one or more computer readable storage media; and
program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the stored program instructions comprising:
program instructions to detect 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;
program instructions to identify one or more environmental parameters associated with an environment surrounding the rollable display device;
program instructions to determine a rolling profile associated with the rollable based on the detected contextual need and the one or more identified environmental parameters, wherein the program instructions further comprise:
program instructions to derive 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;

program instructions to initiate 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
program instructions to adjust an output direction of each micro-speaker in the array of micro-speakers utilizing the respective microfluidics panel.
