Analog area speaker panel with precision placement and direction of audio radiation

摘要

A speaker includes an outer frame, a stretchable membrane material enclosed at least in part by the outer frame; a plurality of movable actuator devices disposed perpendicular to and on one side of the membrane material, each one of the actuator devices being connected to one side of the membrane material. The speaker also includes a controller configured to control creation of one or more radiating speaker elements at any selected instance in time and at corresponding one or more locations at the membrane material by controlling movement of a selected one or more of the movable actuator devices.

1. A speaker comprising:
an outer frame; a stretchable membrane material enclosed at least in part by the outer frame; a plurality of movable actuator devices disposed perpendicular to and on one side of the membrane material, each one of the actuator devices being connected to one side of the membrane material; a controller configured to control creation of one or more radiating speaker elements at any selected instance in time and at corresponding one or more locations at the membrane material by controlling movement of a selected one or more of the movable actuator devices; and an internal frame disposed in proximity to the membrane material, wherein the internal frame is controlled such that portions of the internal frame surrounding the corresponding one or more created radiating speaker elements at any selected instance in time become rigid, thereby damping any vibrations that may originate from the one or more created radiating speaker elements.
