STERLING 'BABY' LOUDSPEAKER HORN, 1923

Designed to replace Headphones on early Wireless sets, before loudspeakers had been perfected because of problems with a strong enough magnet.
The coil is a high enough impedance to connect directly to the output valve of the set. The terminals on the units would carry high voltages, and yet no insulation was thought necessary.
