- Bell & The Invention of Artificial SoundE1
Bell & The Invention of Artificial SoundAlexander Graham Bell is famous for his invention of the telephone. In 1876, his device was the first ever to be able to reproduce sound. Before its invention, nothing existed capable of taking sound waves and replicating them. Bell's invention marks the beginning of our journey through time. This series, of which this video is the first, will be taking you step-by-step through the history of sound reproduction. We begin today with the Telephone. - Edison's Impression: Laying Sound into a GrooveE2
Edison's Impression: Laying Sound into a GrooveBell's invention, the telephone, was the first device capable of reproducing sound. But it couldn't record it. Thomas Edison's invention of the phonograph brought us the first device capable of capturing sound to be played back later. How did Edison figure this out? By combining one of his earlier ideas with the ideas in the telephone, Edison was able to bring a revolutionary product to market (well, sort of). This week, we're exploring how Edison thought up his device. - Emile Berliner's Fix: Flatten the Cylinder to a DiscE3
Emile Berliner's Fix: Flatten the Cylinder to a DiscThomas Edison's cylinder phonograph was fantastic, no doubt. Can you imagine what it would've been like to hear the first artificial sound? But Edison's mind for the accurate doomed his cylinder, because the cylinder as it turns out is a really stupid shape for this sort of a thing. Emile Berliner threw accuracy to the wind with his disc phonograph, assuming people would rather deal with an easier and cheaper phonograph than a more "scientifically correct" one. Boy was he right. We explore Berinler's idea of storing sound in a different way on a different shape in this episode of Technology Connections. - The Vacuum Tube and the Invention of RadioE4
The Vacuum Tube and the Invention of RadioIn today's episode of technology connections, we take a look at the vacuum tube. This simple device had tremendous implications for sound reproduction. We explore how vacuum tubes revolutionized radio, and why they were necessary to make radio practical.
