Radio hat from the year 1949
"A radio in the form of a hat. The American Merri-Lei Corporation
of Brooklyn NY has just brought out a radio receiver in the
form of a hat. It is a 2-tube single-loop battery device with
a 1S5 tube and a 3V4 tube connected as an "Ultraaudion". The
frame aerial can be rotated and there is a knob mounted between
the two tubes for tuning. The circuit can is housed
in the crown of the hat.
There is a built-in earphone for listening. The
1.5 and 22.5 volt batteries can be are carried in the coat pocket
and connected with the "Radio-Hat" by a short lead. ... Extensive tests
carried out in New York show that the sensitivity of this type of device
is sufficient for the reception of local stations."
