SPEAKER APPARATUS AND METHODS USEFUL IN CONJUNCTION THEREWITH

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 one or more actuator devices, each actuator device comprising:
(a) a first electrode and a second electrode; (b) a membrane interposed between the first and second electrodes, the membrane comprising a peripheral flexure and a central portion configured to travel back and forth along a respective axis towards the first and second electrodes in response to an electrostatic force generable by applying a voltage between at least one of the first and second electrodes and the membrane; wherein at least one of the first and second electrodes comprises at least one partial annular opening facing the peripheral flexure of the membrane.
