Abstract: Techniques described herein generally include methods and systems related to a speaker device comprises a planar oscillation element configured to generate an ultrasonic acoustic signal, a shutter element, a first comb drive, and a second comb drive. The shutter element is configured to cover an opening that is positioned to receive the ultrasonic acoustic signal to modulate the ultrasonic acoustic signal such that an audio signal is generated. The first comb drive is coupled to the shutter element and configured to displace the shutter element in a first direction and the second comb drive is coupled to the shutter element and configured to displace the shutter element in a second direction.

Abstract: Techniques described herein generally include methods and systems related to a MEMS-based audio speaker system configured for generating an audio signal. The speaker system includes one or more apertures in the speaker system positioned to receive the ultrasonic carrier signal and one or more movable and over-sized obstruction elements that are configured to modulate the ultrasonic carrier signal and thereby generate an audio signal. Because the movable obstruction elements are configured to overlap one or more edges of the apertures when in the closed position, modulation depth of the generated audio signal can be substantially improved or otherwise varied.
