Safe Case for Ultrasonic Voice Masking

Abstract

In some embodiments, an apparatus that uses ultrasonic signals to mask voice-band signals is provided. The apparatus includes a controller configured to set parameters for ultrasonic signal(s). The apparatus also includes signal generator(s), coupled with the controller, configured to generate electrical signal(s) based on the parameters. The apparatus additionally includes ultrasonic speaker(s), coupled with the signal generator(s), configured to output a first set of ultrasonic signals based on the one or more electrical signals. The apparatus further includes a housing that at least partially supports the controller, the signal generator(s), and the ultrasonic speaker(s), where the ultrasonic speaker(s) output the ultrasonic signal(s) to interfere with voice-band signals recorded by microphone(s) of electronic device(s) placed at least partially inside or near the housing.
