History of Loudspeakers - Speakers
In 1877, German, Ernst Siemens patented
the first loudspeaker on Dec. 14, 1877. Englishmen, Sir Oliver Lodge received
the second patent for a loudspeaker on April 27, 1898. This was all before
music was electrified.
In 1924, two General Electric researchers,
Chester W. Rice and Edward Washburn Kellogg patented the modern, moving
coil, direct radiator, loudspeaker, which become the prominent design for
all loudspeakers The Rice and Kellogg loudspeakers were sold to consumers
under the name of "Radiola'' loudspeakers beginning in 1926, and were superior
to anything previously invented by lowering sound distortion and raising
audio quality for the consumer.
In 1958, the first box-enclosed loudspeakers
were invented by the Cabesse, a French company.
An excellent history of loudspeakers
written by Dr. Steven E. Schoenherr.
A 1925 research paper written by
Chester Rice and Edward Kellogg at General Electric established the basic
principle of the direct-radiator loudspeaker with a small coil-driven mass-controlled
diaphragm in a baffle with a broad midfrequency range of uniform response.
