Twin turntables were illustrated in the BBC Handbook in 1929, and were advertised for sale in Gramophone magazine in 1931. [3] There was an obvious need for such a setup when the normal music format was 78rpm records that played for five minutes at most and a classical symphony came in a box which might contain ten discs or more.
A phonograph, later called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910), and since the 1940s a record player, or more recently a turntable, is a device for the mechanical and analogue reproduction of sound.
The first direct-drive turntable was invented by Shuichi Obata, an engineer at Matsushita (now Panasonic), [11] based in Osaka, Japan. [9] It eliminated belts, and instead employed a motor to directly drive a platter on which a vinyl record rests. [ 12 ]
1877 : The microphone was first invented by David Edward Hughes, despite Thomas Edison being granted the patent. Hughes discovered that electrical currents varied when sound vibrations were passed through carbon packed into a confined space. His first broadcast was of scratching insects.

In a direct-drive turntable the motor is located directly under the center of the platter and is connected to the platter directly. It is a significant advancement over older belt-drive turntables for turntablism, since they have a slower start-up time and torque, and are prone to wear-and-tear and breakage, [5] as the belt would break from backspinning or scratching.
