This loudspeaker was supplied by Western Electric as part
of its early broadcasting equipment. The cone is external
and operated by a pin link to a moving vane type movement.
Previous loudspeakers were essentially a single headphone
coupled to a horn of the sort used on acoustical
The moving coil cone speaker of the type well known today
was invented by Edward W. Kellogg of the General Electric
research lab. Because it requires an enclosure to work
properly it was not immediately popular. Kellogg also worked
on the sound on film system developed at GE. This was
aquired by RCA when the company was formed and marketed as
the RCA Photophone System. Teh existence of this system, a
rival of the Western Electric method, was one reason RCA
invested in RKO. Western Electric had the motion picture
market sewn up and RCA was looking for a way of exploiting
their system. Until about 1935 RKO was the only major studio
using RCA equipment. When the first WE licensing contracts
expired Warner Brothers chose RCA probably because they were
bitter about the way Western Electric / ATT killed Vitaphone
and because RCA had a better deal as far as royalties. Over
the next couple of decades RCA found its way into more and
Western Electric stuff sounded better but WE also wanted
an excessive footage royalty.
Gee-Whiz, what obscure stuff I have stuffed into my brain.
