Product Overview
As along ago as 1856 an instrument was made which was capable of automatically registering sounds, but it was left to Edison, 20 years later, to introduce the first complete phonograph (record player). This consisted of a grooved metal cylinder covered with tin foil, on which the sounds were registered, and afterwards reproduced by means of a steel needle. A conical mouthpiece was attached to concentrate the reproduced sounds. - There is a border around the image. Image size is correct. Many sizes available.
