RADIO RECEIVING MEANS
First Claim
1. Radio frequency receiving means comprising;
- an earpiece assembly having a generally tubular portion insertable in the ear canal;
said tubular portion including an outer metallic portion which contacts the wall of said canal of a user when said assembly is inserted in the ear canal;
said assembly including a transducer with two electrical terminals;
said transducer being mounted on said assembly for the transmission of sound therefrom and through said tubular portion and into said ear canal;
a pair of receiving terminals;
means connecting said metallic portion to one of said receiving terminals;
a lead extending from said assembly and having one of its ends connected to the other one of said receiving terminals; and
quickly attachable and detachable means connected to the other end of said lead, metallic or insulator means connected to said attachable and detachable means whereby the user'"'"''"'"'s body may serve either as ground or an an antenna, respectively.

Abstract
Radio receiving means involving an earpiece assembly which incorporates a transducer for conforming electronic signals into audio energy and which also incorporates a conductive ring for making good conductive connection to the person'"'"''"'"'s ear so that the user himself may serve as an antenna depending upon prevailing radio reception conditions. The earpiece assembly also incorporates a small casing in which a diode is mounted, the diode, transducer and conductive ring being interconnected to a pair of receiving terminals, one of which may be an elongated wire terminating in a clip for releasably fastening to an insulated or metallic element. The diode and transducer are connected in parallel in the simplest form. In some instances an additional diode may be used with the diodes being connected in series with each other and in parallel with the transducer with the diodes being so poled to obtain a circulating current through the transducer. In other modifications, a capacitor may be incorporated either in series with the diode or in series with the transducer for some frequency activity.
