The First Ring Tone (Apr, 1956)

Telephones Will “Ring” With Musical Tones
Telephone users will welcome the news that the Bell Telephone Laboratories is experimenting with a new device that will eliminate the b-r-r-r-ing of present-day instruments. The gadget, using transistors, will produce pleasant musical tones resembling those of a clarinet. Sound emanates through the louvred area at the base of the set, shown in the photo with a white background.
This device requires less than 1 volt for operation; the ordinary telephone bell needs about 85 volts. A full-scale field trial of the new equipment is expected to provide enough technical data and customers’ reactions to help determine its future.
