Historical Context
The International Radio Corporation was incorporated in Delaware in 1922 and was based in Newark, New Jersey.
The company produced a radio speaker (known as the Richtone) as well as radio condensors. The Richtone used ten graduated chambers to stimulate soundwave vibrations and project the sound through a curved projector.
The company appears to have been short-lived as there is no record of any real commercial success.
