Patent Images
1. An apparatus comprising:
- a head-mountable support structure;
a transducer array coupled to the support structure;
a processor configured to control the transducer array to radiate ultrasonic waves toward an ear of a user of the head-mountable support structure, wherein the processor is further configured to control the transducer array to radiate a steerable beam of ultrasonic waves; and
a touchpad coupled to the processor and configured to receive instructions to steer the steerable beam.

9. A method comprising:
-
controlling a transducer array coupled to a head-mountable support structure to radiate ultrasonic carrier waves toward an ear of a user of the head-mountable support structure; controlling the transducer array to radiate ultrasonic signal waves toward the ear of the user, wherein the ultrasonic signal waves include audio signals; producing a beam of audible sound from an interaction between the ultrasonic carrier waves and the ultrasonic signal waves, wherein the beam of audible sound is radiated toward the ear of the user; and receiving instructions, via a touchpad associated with the head-mountable support structure, to steer the beam of audible sound. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A head-mountable device, comprising;
-
a support structure; a transducer array coupled to the support structure, wherein the transducer array includes at least a first ultrasonic transducer and a second ultrasonic transducer; a processor configured to control the first transducer to radiate ultrasonic carrier waves and to control the second transducer to radiate ultrasonic signal waves, wherein the ultrasonic signal waves includes audio signals, further wherein an interaction between the carrier waves and the signal waves results in a beam of audible sound; and a touchpad configured to receive instructions to steer the beam of audible sound. - View Dependent Claims (17, 18)
