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.
Claims25
A wearable communication device comprising:
- a receiver, wherein the receiver receives audio information;
- a pre-processing module connected with the receiver, wherein the pre-processing module modifies the received audio information;
- a modulation module connected with the pre-processing module, wherein the modulation module modulates the modified audio information;
- an amplification module connected with the modulation module, wherein the amplification module amplifies the modulated audio information;
- a channel splitter connected with the amplification module, wherein the channel splitter splits the amplified audio information into a first channel and a second channel;
- an ultrasonic loudspeaker connected with the channel splitter, wherein the ultrasonic loudspeaker receives and emits the amplified audio information from the first channel;
- and
- a low frequency loudspeaker connected with the channel splitter, wherein the ultrasonic loudspeaker receives and emits the amplified audio information from the second channel.
A device comprising:
- a receiver, wherein the receiver receives audio information;
- a pre-processing module connected with the receiver, wherein the pre-processing module modifies the received audio information;
