ST. CHARLES, ILL.,, Feb. 9.-tP-A
loud speaker, different from any
heretofore familiar to radio. has been
developed here. 1t il based on the
principle OF a condenser
The speaker, the result Of the ef-
forts OF Colin Kyle, a former Cali
fornia school teacher, consist of
two metallic plates separated Ky
special dielectric named -KyIite"
after the inventor. The unit is
flooded with loT-current, high-volt-
age electrical energy 20 provide

The method il similar to that Of
charging an electrical condenser.

and u cola tube as a rectifier. The
current drain Is only three TO four
milliamperes. The polarizer is built
into the speaker.
In discussing the speaker, Mr..
Kyle said that it gave 'the most
direct conversion OF electrical energy
to sound Of n development To date"

high and low voice ~frequencies with

No moving parts are required, he
explained. The output from q receiv-
er is delivered directly 20 the dia-
phragm or plates of the speaker
without passing through coils in mag
netic fields. The entire surface of
the diaphragm receives the impulses
and vibrates in phase with every
other portion Of the surface. There
Is no hum.
Mr.. Kyle said that the design and
shape of the speaker, to which he re-
ferred as athe condenser type may

place shield or n screen Because
Of its thinness, il lends itself TO many
unique designs. In adapting ii to q
radio receiver, he said that IL could
be placed in the front panel or in the
cover. He said that the speaker
would function with any type OF
amplifier or output tubes, adding
that its "sensitivity is easily ap-
parent in comparison with standard
makes"
The units Of the speaker are made
In sections. approximately ~ by 70
inches. From three 70 six sections
sre put into each speaker, six seem

ley laboratories here. where Mr.. Kyle
has been working Oh the problem
since last February.

for several years. Recently a de-

demonstrated in this country. u
