Abstract
A compact portable radio is provided, comprising a disk-like body. The radio has the usual circuitry for detecting and amplifying a radio (AM or FM) signal, an earphone assembly comprising a speaker adapted to be received by the ear of the listener and secured to a head band adapted to partially encompass the head of the listener and a wire for conveying the amplified radio signal to the speaker, and volume control. The disk-like body is provided with storage space for storing the wire and also the head band and at least a portion of the speaker. Such storage space provides a facile way of keeping the wire and earphone assembly from becoming tangled when the radio is not in use.
