Methods and systems are provided for ultrasonic emitter based audio devices. An example audio device may comprise one or more ultrasonic emitters. The audio device may generate audio outputs that comprise ultrasonic signals, with the ultrasonic signals emitted using the one or more ultrasonic emitters. The directionality of emission of the ultrasonic signals may be based on a position of a listener and/or a location of the at least part of the listener's body relative to the audio device. The ultrasonic signals and/or the positioning of the one or more ultrasonic emitters may be adjusted based on the position of the listener and/or the location of the at least part of the listener's body to optimize the directionality of emission of the ultrasonic signals. The position of the listener and/or the location of the at least part of the listener's body may be determined in real-time, such as using sensory information.
