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; and
b) an earplug for insertion into an ear canal of a user, comprising;
i) a receiver comprising a loop of wire; and
ii) a speaker coupled to the loop of wire of the receiver;
such that when the earplug is placed in a user'"'"'s ear canal and the loop transmitter is placed around the pinna of the user'"'"'s ear, and an audio 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.

11. A communications headset comprising a pair of earmuffs for surrounding the user'"'"'s ears, linked by a resilient headband, each earmuff comprising:
-
a) a loop transmitter mounted within each earmuff, comprising a coil of wire having an open center sized to fit around a pinna of a user'"'"'s ear; and b) an earplug for insertion into an ear canal of each ear of a user, comprising; i) a receiver comprising a loop of wire; and ii) a speaker coupled to the loop of wire of the receiver; such that when the earplug is placed in a user'"'"'s ear canal 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 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 (12, 13, 14, 15, 16, 17)

18. A battery-free wireless earplug for insertion into an ear canal of a user, comprising:
-
a) a receiver comprising a length of wire having two ends and a length therebetween 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; b) a speaker coupled to the ends of the wire of the loop in the receiver, the electrical voltage on the ends of the wire driving the speaker to produce sound; and c) a molded earshell having a body and an eartip for insertion into the ear canal of the user, the receiver and the speaker being located within the earshell with the speaker mounted to direct sound into the eartip; such that when the receiver is subjected to a magnetic flux from an audio signal introduced into a loop transmitter outside of the ear canal of the user, the magnetic flux from the loop transmitter drives the speaker to provide sound into the user'"'"'s ear. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
