The phonautograph is the earliest known device for recording sound. Previously, tracings had been obtained of the sound-producing vibratory motions of tuning forks and other objects by physical contact with them, but not of actual sound waves …

2008年4月4日 · Audio historians have found a sound recording that predates Edison's phonograph by nearly 20 years. The "phonautograph" was patented in 1857 by Edouard-Leon Scott de Martinville; the device...

2020年3月1日 · The phonautograph was coined after the daguerreotype which is considered as the prototype of the first camera. It was patterned with the human ear, working on vibrations with a vibration membrane called the eardrum to facilitate and process these vibrations.

This invention (patented on March 25, 1857) called Phonautograph paved the way for the future inventors who introduced to the world not only better capable sound recording devices, but also sound reproducing devices.

2017年7月17日 · Edouard-Léon Scott de Martinville invented sound recording 20 years before Thomas Edison invented the phonograph. Sound had been invisible and transient since the beginning of time. Scott’s phonautograph recorded it and made it both visible and perm­anent. It was a technological breakthrough, ahead of its time.

French typographer Édouard-Léon Scott de Martinville invented the phonautograph, a machine to make a visual record of sound waves traveling through the air. First patented in 1857 and revised repeatedly, his design would influence the direction of sound studies.

Leon Scott's phonautograph, invented as far back as 1857, had demonstrated that ambient sound waves could be traced as a visual image through the vibrations of a bristle on a sheet of soot-covered paper, known as a phonautogram.

The result of his work was first sound recording device known to man - Phonautograph. Created in 1857 after three years of work, phonautograph consisted of cone-shaped speaking horn with flexible moving diaphragm connected to his smaller end.

The phonautograph made sounds both visible and permanent. It was one of the first instruments to graph natural phenomena, and as such it was used in laboratories and universities for decades. It informed the nascent field of acoustics.

Edouard-Leon Scott de Martinville was born in France in 1817. As a printer by trade, he was able to read accounts of the latest scientific discoveries and became an inventor. On March 25, 1857, he received French patent #17,897/31,470 for the phonautograph.
