Wireless Communications Headset System Employing a Loop Transmitter that Fits Around the Pinna
First Claim
1. A communications system comprising:
- a) a loop transmitter comprising a coil of wire having an open center sized to fit around a pinna of a user'"'"'s ear;
b) an earplug for insertion into an ear of a user, comprising;
i) a receiver comprising a loop of wire;
ii) a speaker coupled to the wire of the receiver;
such that when the earplug is placed in a user'"'"'s ear and the loop transmitter is placed around the pinna of the user'"'"'s ear, and an audio electrical signal is introduced into the wire of the loop transmitter, a magnetic flux is created which is inductively coupled to the loop of wire of the receiver and converted into an electrical voltage, the voltage driving 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.

10. A communications headset comprising a pair of earmuffs for surrounding the user'"'"'s ears, each earmuff comprising:
-
a) a loop transmitter mounted within each earmuff, comprising a coil of wire; and b) an earplug for insertion into an ear of a user, comprising; i) a receiver comprising a loop of wire; ii) a speaker coupled to the wire of the receiver; such that when the earplug is placed in a user'"'"'s ear and the headset is put on the user'"'"'s head such that the loop transmitter within each earmuff is placed around the pinna of the user'"'"'s ear, and an audio electrical signal is introduced into the wire of the loop transmitter, a magnetic flux is created which is inductively coupled to the loop of wire of the receiver and converted into an electrical voltage, the voltage driving the speaker to provide sound into the user'"'"'s ear. - View Dependent Claims (11, 12, 13, 14, 15, 16)
