'Spica' is an old brand (which still exists) for portable radios. It was the first to use transistors and AA batteries, which gave it a practical size to carry everywhere. It was manufactured by Sanritsu Electric Co. Ltd. from Japan from 1955, and was exported to a large number of countries, which gave it its international fame. However, its main buyer was the USA, which influenced the origin of the brand as it resembles the English speaker (spica "speaker, speaking, speaker"), which also has its Latin etymology in spicare ("vocear, highlight to the ear" ), by spica, ae ( "spike, peak, which protrudes") .
