Radio receiving means
Abstract
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.
