Wireless communications headset system employing a loop transmitter that fits around the pinna
First Claim
1. A communications system comprising:
- a loop transmitter comprising a coil of wire; and
an earplug to insert into an ear of a user, the earplug comprising;
a receiver including a wire; and
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 near the a pinna of the user'"'"'s ear, and an audio electrical signal is introduced into the coil of wire of the loop transmitter, a magnetic flux is created which is inductively coupled to the 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.

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