ABSTRACT:
A miniature radio and two speakers, one for each ear, are releasably attachable to a pair of spectacles. The speakers are remote from the radio and connected to it through speaker wires. In a first embodiment, a truncate primary tube releasably engages a trailing end of each spectacle ear piece, and the radio is clipped to one of the primary tubes. All but the opposite ends of the speaker wires are housed within an elongate, flexible tube that interconnects the respective free ends of each truncate primary tube to one another. The elongate, flexible tube has exit openings at its opposite ends, and the opposite ends of the speaker wires extend through the exit openings and through respective auxiliary tubes that are secured to the primary tubes that engage the respective ear pieces of the spectacles. In this way, the spectacle ear pieces do not contact the opposite ends of the speaker wires when the ear pieces are inserted into the truncate primary tubes. In a second embodiment, the exit openings are eliminated and the speaker wires are housed between a pair of flaps that extend from the elongate, flexible tube. The opposite ends of the speaker wires enter the respective auxiliary tubes directly from the opposite ends of the flaps. In further embodiments, the elongate, flexible tube may be a flexible rod and the flaps are replaced by a tube.
