Abstract: A system that includes a direct digital speaker volume control device configured to be coupled to a direct digital speaker. The direct digital speaker include many pressure producing elements being adapted to generate a sound at a sound pressure level (SPL) and at a given frequency in response to an input signal, without using digital to analog converter. The direct digital speaker inherently exhibits a frequency response throughout its entire frequency range. The direct digital speaker volume control device includes a module for providing few filters each having a distinct cutoff frequency such that each filter exhibits no attenuation below its cutoff frequency and an attenuation response above the filter's cutoff frequency. And a selector for selecting one of the filters according to a selection criterion that depends on a desired volume and frequency of generated sound, and applying the filter to the input signal for generating a filtered signal that fed to the speaker.

Abstract: An actuator array for generating sound, the actuator array comprising at least one actuator device, the at least one actuator device including:
(a) a first latching electrode (4010) and, optionally, a second latching electrode (4050);
(b) a flexure (4030) interposed between the first and second electrodes (4010, 4050), the flexure (4030) 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 towards the first and second electrodes (4010, 4050) in response to an electrostatic force generable by applying a voltage between the first and second electrodes (4010, 4050) and the flexure (4030);
wherein the first and second electrodes (4010, 4050) comprise partial annular openings facing the peripheral flexible elements of the flexure (4030).
