Chronomégaphone

From Wikipedia, the free encyclopedia
Illustration of a theater from the rear right of the stage. At the front of the stage a screen hangs down with the projected image of a tuxedoed man holding up a text and performing. In the foreground is a gramophone with two horns. In the background, a large audience is seated at orchestra level and on several balconies. The words "Chronomégaphone" and "Gaumont" appear at both the bottom of the illustration and, in reverse, at the top of the projection screen.

The Chronomégaphone, designed for large halls, was a compressed air gramophone which employed compressed air to amplify the recorded sound.[1] It was used by Gaumont for the presentation of some of their early sound films.[2]
