摘要

An actuation system for generating a physical effect, the system comprising at least one array of translating elements each constrained to travel alternately back and forth along a respective axis, toward first and second extreme positions respectively, in response to activation of first and second forces respectively; and a controller operative to use the first and second forces to selectably latch at least one subset of said translating elements into the first and second extreme positions respectively.

主权项

1. An actuator array for generating sound, the actuator array comprising at least one actuator device, the at least one actuator device including:
(a) a latching electrode; (b) a flexure comprising one or more flexible elements peripheral to and integrally formed with a central portion, the central portion being configured to travel back and forth along a respective axis perpendicular to the latching electrode in response to an electrostatic force generable by applying a voltage between the latching electrode and the flexure; (c) an insulation layer separating the latching electrode from the flexure.
