Methods and systems are provided for ultrasonic emitter based floor audio units. An example floor audio unit may comprise one or more ultrasonic emitters and may be placed on or near a floor. The floor audio unit may generate audio output that comprises ultrasonic signals, and may emit the ultrasonic signals using the one or more ultrasonic emitters, where the one or more ultrasonic emitters may be configured to emit the ultrasonic signals upward. Further, directionality of emission of the ultrasonic signals is based on a position of a listener and/or a location of the listener's head relative to the enclosure of the floor audio unit. 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 listener's head to optimize the directionality of emission of the ultrasonic signals. |
