Section of telephone, after Bell

Paris 1880? Ducretet

The patent for the invention of the telephone is in the name of Alexander Graham Bell (1847-1922). His telephone horn could both record sound and reproduce sound. The sound of a voice sets a membrane, to which a small magnet is attached, into vibration. In a coil the vibrating magnet generates an induced current, which is led through a wire to a receiver. In the receiver a reverse process sets a membrane into vibration, which reproduces the recorded sound. This French demonstration model was made by Eugene Ducretet (1844 -1915), an instrument maker specialized in electric devices. In 1880 the device was acquired through the Haarlem instrument maker Friedrich Wilhelm Funckler (1832-1886,) who worked a lot for the Teylers Museum.
