Abstract
Techniques described herein generally relate to generating an audio signal with a speaker. In some examples, a speaker device is described that includes a membrane and a shutter. The membrane can be configured to oscillate along a first directional path and at least one frequency effective to generate an ultrasonic acoustic signal. The shutter is positioned along the propagation of ultrasonic acoustic signal and configured to modulate the ultrasonic acoustic signal such that an audio signal is generated.
