Built-in miniature radio antenna

摘要

A miniature radio antenna formed integral with a molded plastic housing comprising a body 1 and a cover 2. The antenna 1', 1'', 2', 2'' includes sheets, foils or films of electrically conductive metal or coats of conductive paint laid on the inside surfaces of the opposing housing sections, or conductors embedded therein. The antenna is free from adverse acoustic effects due to resonant vibrations in sympathy with a speaker mounted in the housing, and the housing may be molded into any desirable external shape, including fully rounded corners, without increasing the size.
