The vibrator you are talking about was used in older radio's to convert DC
voltage into AC Voltage for the tube circuits to operate.
The new replacement for the old vibrator is a device call solid state and
they do not hum.

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.

Don't hold me to this, but I think what this might be referring to is what
they called back in the late 60's or early 70' as a reverb unit. 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.
