Edison's phonograph. 19th-century artwork of the phonograph developed in 1877 by US inventor Thomas Alva Edison (1847-1931). This device both recorded and recreated sounds using a foil-wrapped cylinder (upper right). Sound waves made the receiver vibrate, leaving a trace on the foil as the cylinder was turned. The recorded sound could then be recreated by attaching listening tubes (bottom) to the receiver, adjusting the position of the needle to the start of the trace, and rotating the cylinder. Distorted but recognisable sounds were produced. This wood engraving dates from circa 1888.
