With the clear danger of aging myself, I also recall that prior to the 60's and 70's there was a "vibrator" in radios that was a mechanical relay type device that converted the 6v DC to AC to run it through a transformer to increase the voltage for some purposed in the radio. That went away with transistor radios and with 12v along with other technological advances.

This was usually mounted in the trunk or where ever you found room and was connected to your radio, 8 track or both and created a delay between the front and rear speakers giving a echoing type sound to simulate stereo. I remember one of my friends installed one of these units in his at the time new Pontiac Tempest. It really didn't sound too bad for the time. Something different that didn't last very long.
