Wireless communications headset system employing a loop transmitter that fits around the pinna
First Claim
1. A communications system comprising:
- a battery-free wireless earplug for insertion into an ear of a user, comprising;
i) a receiver comprising a wire having two ends and a length there between formed into a loop having a plurality of turns, such that magnetic flux passing through the loop is converted into an electrical voltage on the ends of the wire;
ii) a speaker coupled to the wire of the loop in the receiver, the electrical voltage on the ends of the wire driving the speaker to produce sound; and
iii) an earshell for insertion into the ear of the user, the receiver and the speaker being located within the earshell with the speaker mounted to direct sound into the user'"'"'s ear canal;
such that when the earplug is placed in a user'"'"'s ear and the receiver is subjected to a magnetic flux from an audio signal introduced into a loop transmitter outside of the ear of the user, the magnetic flux from the loop transmitter drives the speaker to provide sound into the user'"'"'s ear.

Abstract
A wireless communications headset system for double hearing protection systems that eliminates the problems associated with typical wireless communications systems. The system employs a magnetic-field coupled wireless link from a loop transmitter to a magnetic field receiver. Current through the transmitter wire loops generates magnetic flux which passes through a communications earplug. The earplug has a receiver for converting the magnetic flux to electrical voltage, and this voltage is used to drive a speaker within the earplug. The transmitter can be easily installed into aviation headsets. The loop transmitter has an open center sized so that it fits around the pinna of the human ear enabling a close position to the communications earplug. This close position is advantageous if an efficient system is desired.
