Ear radio
First Claim
1. A self-contained, fully operational radio receiving device adapted in size and configuration for implacement and retention at the entrance to an ear canal, said device being self-supported by surrounding ear cartilage which defines a casement support chamber, said device further comprising:
- a casement having an outward and an inward housing as viewed in relation to casement position at the ear canal;
radio circuitry contained within the outward housing and positioned on an integrated circuit chip, said circuitry including (i) signal receiving means comprising a cylindrical antenna core positioned for axial orientation toward the ear canal for receiving radio transmissions, (ii) demodulating circuitry including an rf resonant circuit for selecting a desired transmission frequency and (iii) amplifying and filtering circuitry for producing a clear radio signal;
a power source coupled to the circuitry for powering circuit operation; and
speaker means contained within the inward housing of the casement and coupled directly to the amplification circuitry for receiving and converting said audio signals to audible sound, said speaker means being structured for directional orientation toward the ear canal;
said casement having maximum outside width dimensions smaller than the greatest distance across the casement support chamber at the ear canal entrance and no greater than approximately 3/4 inch, said casement having a length from distal sides of the inward to outward housing of less than approximately one inch.

Abstract
A self-contained, fully operational radio device adapted in size and configuration for implacement and retention at the entrance to an ear canal, said device being fully self-supported by surrounding ear cartilage, thereby eliminating any need for connecting wires or other radio circuitry. The device includes a casement having an outward and an inward housing for containing the respective radio circuitry and speaker means for the radio device. A battery is also contained within the outward housing for powering the radio system. The maximum outside dimensions of the radio device and enclosed radio circuitry are less than 3/4 of an inch in diameter and one inch in length. Various functional controls are provided for convenient operation of on/off, frequency selection, and volume level.
