Abstract
The privacy-preserving energy-efficient speaker implementations described herein improve user privacy while a user is listening to audio and can reduce the energy necessary to output the audio. This can be done by using parametric speakers and/or traditional loud-speakers. Signal splitting and masking can be used to improve user privacy. Additionally, a signal modulation technique which significantly reduces power requirements to output an audio signal, especially in the context of using parametric speakers, can also be employed.
