Who invented gramophone

Alexander Graham Bell and his associates at the Volta Laboratory set out to best Thomas Edison’s original phonograph. They were convinced of the profit-making potential of an improved device—especially one that could capture more clearly the speaking voice for business dictation. They originated wax cylinder records, and developed a machine to record and play them, the graphophone. Listening at Work Inventors and investors saw recorded sound not as a source of entertainment, but as a tool for business. And new corporations looked to “talking machines” to increase efficiencies in their ever-growing managerial departments. But the devices enabled new workplace hierarchies, with male managers upstairs recording dictation that female typists downstairs played back and put to paper. Volta Labs Recordings, 1880-1885 The inventions of Alexander Graham Bell—most famously the telephone but also methods of recording sound—have allowed people to hear each other’s voices for more than 130 years. Until now, no one knew what the inventor himself sounded like. The Smithsonian’s National Museum of American History, through a collaborative project with the Library of Congress and Lawrence Berkeley National Laboratory, has identified Bell’s voice for the first time. In the museum’s collection from Bell’s Washington, D.C., Volta laboratory, which includes 200 of the earliest audio recordings ever made, was a loose piece of paper discovered by researchers to be a transcript of a recording.

Learn how Alexander Graham Bell went to revolutionize telegraphy but instead invented the telephone Alexander Graham Bell, (born March 3, 1847, Edinburgh, Scotland—died August 2, 1922, Beinn Bhreagh, Cape Breton Island, Alexander (“Graham” was not added until he was 11) was born to Alexander Melville Bell and Eliza Grace Symonds. His mother was almost deaf, and his father taught A History of Everyday Technology in 68 Quiz Questions One of Bell’s students was While pursuing his teaching profession, Bell also began researching methods to transmit several A group of investors led by Gardiner Hubbard wanted to establish a federally chartered telegraph company to compete with Western Union by contracting with the Post Office to send low-cost telegrams. Hubbard saw great promise in the harmonic telegraph and backed Bell’s experiments. Bell, however, was more interested in transmitting the human voice. Finally, he and Hubbard worked out an agreement that Bell would devote most of his time to the harmonic telegraph but would continue developing his telephone concept. Graphophone By that time, Bell had developed a growing interest in the Volta Laboratory, an institution devoted to studying Bell undertook two other noteworthy research projects at the Volta Laboratory. In 1880 he began research on using Bell’s other major undertaking was the development of an electrical bullet probe, an early version of the metal detector, for surgical use. The origin of this effort was the shooting ...

In 1887, Emil Berliner (1851–1921) invented the gramophone, the mechanical predecessor to the electric record player. Later, with the shellac record, he developed a medium that allowed music recordings to be mass produced. As a smart businessman, the German-American knew how to market his patents and founded one of the first major record labels. Emil Berliner (1851-1921) was the inventor of the gramophone and the shellac record. The German-American's first significant invention, however, was the carbon microphone, which he developed at the same time as Hughes and Edison. He sold his patent in 1877 to Alexander G. Bell in a lucrative deal, who used it as a component of the Bell telephone. The sale made Berliner financially independent, and as a result, he was able to found his own research laboratory. Berliner's inventions: In 1887, Emil Berliner obtained the US patent for the gramophone and the associated record. The mechanical predecessor to the electric record player was born. A major improvement to his speech device, which was filed for patent in 1887, was the zinc record. Unlike the Edison cylinder, the sound track here is created using the lateral recording process on the recording medium. The early gramophone had a horn made of papier-mâché, which is firmly connected to the tonearm and the sound box. The hand crank is used to set the record in motion, which produces the sound. In the first decade of the 20th century, large horn gramophones were considered modern. Lat...

Wave Theory Machine Theory of Waves In 1806 the Physicist Thomas Young (1773-1829), expounded his wave theory, a part of which was a means of displaying sound as wavy lines on a drum. Young was more concerned with the nature of sound than a possible recording medium. (see picture) Early Origins in Dictation Machines The first recording machine is at present attributed to the Frenchman Ed Ouardd-Leoan Scott De Martinville (1817-1879) who invented his Phonautograph in 1857. It could transcribe sound onto a blackened glass plate and, later, onto blackened paper on a drum. He had no means of playing it back (in 2008 his sounds were reproduced optically and In 1877 Thomas Edison developed a machine that, for the first time in history, recorded speech and played it back (see picture). It was based on machines that recorded Morse code but, instead of dots and dashes, a stylus was attached to a diaphragm and the vibration up and down inscribed on a cylinder covered in tin foil. The idea was patented in 1878. The machine did not become popular as the recording medium was not suitable for extended use and would need to be replaced each time. Edison with the first Phonograph In 1886, in Washington DC, Charles Sumner Tainter and Chichester Bell, cousin of A.G. Bell the inventor of the telephone, patented an improved Phonograph called the In the early 1890's Tainter, Bell, and Edison's companies turned to the more profitable line of music. Arcades for coin-in-the-slot phonographs spran...

History of Gramophone - Who invented Gramophone? History of sound recording and playback became forever change in 1850s with the discovery of first Phonautograph by the hands of French inventor Édouard-Léon Scott de Martinville, and his lifelong quest to obtain more knowledge about spoken and written human language. His efforts soon became obsession of two famous American inventors - Thomas Ava Edison and Alexander Graham Bell, whose competition in the fields of electricity, telegraph, and telephony soon gave birth to the new generation of this sound processing devices that are today called gramophones. Edison's monumental discovery of Phonograph in 1877 enabled users to freely record and playback any sound, but his reliance on the tinfoil paper as an information storage medium was criticized for being ineffective, had to use and very fragile. Because of that, Alexander Graham Bell and his workers at Volta factory started experimenting, and came to conclusion that cylinder made out from wax could much withstand repeated use, perform better with recording and playback, have capacity for longer playback, and was easier to manufacture than Edison tinfoil design. Because Edison patented only recording and reproduction from tinfoil medium, Bell did not have problem patenting his much superior wax based design, and from that point his " graphophones" became a standard in a world of sound processing. Another very important fact that enabled the rise of its popularity was the abil...
