1. A portable communication system comprising:
- an infrared transmitter apparatus, wherein the infrared transmitter apparatus comprises;
at least one infrared light emitting device,modulation circuitry operable to convert a signal to one or more constant width electrical pulses to drive the infrared light emitting diode to transmit one or more corresponding constant width infrared pulses, anda transmitter housing enclosing the modulation circuitry and upon which the at least one infrared light emitting device is mounted; and
an infrared receiver apparatus, wherein the infrared receiver apparatus comprises;
an infrared light detection device to detect the one or more corresponding infrared pulses and generate one or more electric signals representative of the detected infrared pulses,a speaker,demodulation circuitry operable to convert the one or more electric signals representative of the detected infrared pulses to an audio signal to power the speaker to produce a sound output, anda receiver housing enclosing the speaker and the demodulation circuitry and upon which the infrared light detection device is mounted, wherein the receiver housing is formed to be self-supported entirely by the ear of a user.

Abstract
A portable communication system provides a universal transmitter that mechanically couples to a communication device having a sound output, e.g., a cellular phone handset, and which transforms the sound output into infrared signals, e.g., pulses, for transmission to a wireless receiver, e.g., a behind the ear or in the ear receiver.
