The Chronophone is an apparatus patented by Léon Gaumont in 1902 to synchronise the Cinématographe (Chrono-Bioscope) with a disc Phonograph (Cyclophone) using a "Conductor" or "Switchboard". This sound-on-disc display was used as an experiment from 1902 to 1910. In January 1911, the industrial exploitation started at the Olympia . Chronophone would show Phonoscènes (an early forerunner of music videos ) and films parlants ("Talking Films") almost every week from 1911 until 1917 at the Gaumont Palace , "the Greatest Cinema Theatre in the World", previously known as the Paris Hippodrome.
4-784: A later version of the Chonophone was known as a Chronomegaphone . A Chronophone is preserved in the collection of the Musée des Arts et Métiers , another is in the collection of the George Eastman Museum , and a Chromomegaphone is owned by Gaumont . In the United States , the early rival of the Chronophone was the Cameraphone, which included a Graphophone with a type of mechanical sound amplifier known as

Chronomegaphone Compressed air gramophones were gramophones which employed compressed air and a pneumatic amplifier to amplify the recorded sound. One of the earliest versions was the Auxetophone , designed by the Anglo-Irish engineer Sir Charles Parsons . It
12-400: The flow of a stream of compressed air . The basic principle of the valves used in these devices was to pass the stream of compressed air through two partially overlapping combs. The sound vibrations to be amplified were applied to one of the combs, causing it to move laterally in relation to the other comb, varying the degree of overlap and so altering the flow of compressed air in sympathy with
16-616: Was capable of producing sufficient volume to broadcast public music performances from the top of the Blackpool Tower , and was said to be loud enough to cause people to vacate the front rows of seats in an auditorium. The Auxetophone was sold in the United States as the Victor Auxetophone . A pneumatic amplifier was realised by using a sensitive valve, which required little force to operate, to modulate
