Dolls Dance to Radio Music (Mar, 1932)
Dolls Dance to Radio Music
FROM Germany comes the latest radio novelty. It is a platform upon which a group of dolls dance to the tune of music issuing from your radio receiver.
The device is a mystery until you understand the dance platform is caused to vibrate by means of a small needle which connects with a headphone, as illustrated in the accompanying drawing.
This headphone is connected up with your radio receiver, so that the same current sounds the music and excites the dancers. The effect of the contrivance is extremely fascinating.
