Abstract

A handphone is configured to receive a first audio signal of a telecommunication conversation from a telecommunication device and send a second audio signal of the telecommunication conversation to the telecommunication device. A modulated ultrasound frequency audio signal that is directional is created from the first audio signal of the telecommunication conversation. The modulated ultrasound frequency audio signal is output via a loudspeaker. A direction of the modulated ultrasound frequency audio signal is controlled by a physical object and a location of the loudspeaker.

Claims

1. A system comprising:

an audio device having a main enclosure with a display and including a first transducer;

an ultrasonic loudspeaker;

a waveguide extending from the main enclosure to the ultrasonic loudspeaker and placing the first transducer in communication with the ultrasonic loudspeaker.

2. The system of claim 1, wherein the waveguide includes an acoustically reflective surface.

3. The system of claim 1, comprising a band extending from the main enclosure and having the waveguide disposed within the band

6. The system of claim 1, further comprising a reflector positioned in the main enclosure and configured to direct energy from the first transducer to the waveguide.

7. The system of claim 1, further comprising a second transducer positioned between the waveguide and the ultrasonic loudspeaker.

8. The system of claim 1, wherein the main enclosure is associated with a ring.

9. A wearable communication device comprising:

a receiver for receiving audio information;

a pre-processing module connected with the receiver for modifying the received audio information;

a modulation module connected with the pre-processing module for modulating the pre-processed audio information;

an amplification module connected with the modulation module for amplifying the modulated audio information; and

an ultrasonic loudspeaker connected with the amplification module to receive and to emit the amplified audio information.

10. The device of claim 9 further comprising a main enclosure having disposed therein the receiver and the pre-processing module and further comprising a transducer disposed within the main enclosure.

11. The device of claim 10, further comprising a waveguide connected to the main enclosure for transmitting the amplified audio information to an ultrasonic loudspeaker positioned external from the main enclosure and configured to emit the amplified audio information.

12. The device of claim 11, further comprising a band including the waveguide.

14. The device of claim 12, further comprising a reflector configured to reflect energy from the transducer into the waveguide.

15. The device of claim 14, further comprising a second transducer positioned between the ultrasonic loudspeaker and the waveguide.

17. The device of claim 9 further comprising a channel splitter and a low frequency loudspeaker, wherein the channel splitter splits the amplified audio information into a first channel and a second channel, the first channel in communication with the ultrasonic loudspeaker and the second channel in communication with the low frequency loudspeaker.

21. The device of claim 9, further comprising a motion sensor.

23. The device of claim 9, further comprising a light source providing a directional beam, the directional beam corresponding with a path of amplified audio information emitted by the ultrasonic loudspeaker.
