Phonograph

phonograph is an instrument that plays recorded sound. The sound Phonograph was recorded on a grooved disc called a phonograph record. The phonograph was often referred to as the ‘talking machine The phonograph has a rotating record and a needle-like structure called a stylus. Phonograph records are dises that store sounds, which can be replayed
The phonograph, invented in 1877, was a popular device for playing recorded sound. However, since the 1980s, it lost its popularity and is now rarely used
Phonautograph
Phonautograph was a mechanical sound recording device. It was invented by the French
inventor, Edouard-Leon Scott de Martinville. Edouard-Leon Scott received the patent for his
phonautograph on 25 March 1857. Sound was collected by a horn. The horn had a diaphragm at its end that vibrated when sound passed through it. A bristle attached to the diaphragm recorded the movement of the sound on a blackened paper. The device, however, did not play back the recorded sounds
Disc record gramophone


The disc record gramophone was invented by a German-born American scientist, Emile
Berliner. He received the patent for the disc record gramophone on 8 November 1887
Berliner’s gramophone was the first record player to use discs. The disc was used to record
sound. The gramophone had a sensitive needle that moved along the grooves in the record. The needle picked up the vibrations, which were ther converted to sound by the microphone.
Gramophone records
Gramophone records are flat circular discs with spiral grooves. These records can be played on a phonograph. The first records were made of glass and zinc. Later, they were made from plastic.
Paleophone
The paleophone was the first proposed instrument to record and replay sounds. It was designed by M. Charles Cros, a French inventor, in 1877, Cros proposed making a device that would have a diaphragm on which sound would be engraved and replayed. But before Cros could construct a working model of the paleophone, Edison invented the phonograph in the United States.
Microphone
The first microphone was invented by Emile Berliner in 1876. Berliner invented the microphone to act as a voice transmitter in phones. Later, he used it in his gramophone to convert sound into electric signals. The sounds were then amplified and recorded.
Phonograph
Thomas Alva Edison invented the first phonograph in 1877. The phonograph recorded sound on a tinfoil sheet wrapped around a grooved cylinder with a stylus. The stylus moved up and down and recorded the sounds as indents on the tinfoil. There was a hand crank
attached to the cylinder in order to turn it during play also while recording. Using his phnograph Edison recorded and played back human voice for the first time. Edison happened to hit upon the idea of developing a phnograph when he was working on improving the telephone and the telegraph. The first words that Edison recorded were ‘Mary had litle lamb, its fleece was white as snow, and everywhere that Mary went, the lamb was sure to go Edison demonstrated his phnograph to the American Academy of Sciences in Washington in 1876. Edison established the Edison Speaking Phnograph Company in 1878.
