Ring-and-spring microphones, such as this Western Electric microphone, were common during the electrical age of sound recording c. 1925–45..

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 groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side.
Thomas A. Edison invented the phonograph, the first device for recording and playing back sound, in 1877.After patenting the invention and benefiting from the publicity and acclaim it received, Edison and his laboratory turned their attention to the commercial development of electric lighting, playing no further role in the development of the phonograph for nearly a decade.
The first cylinders were wrapped with tin foil [2] but the improved version made of wax was created a decade later, [3] after which they were commercialized. In the 1910s, the competing disc record system triumphed in the marketplace to become the dominant commercial audio medium. [4]
Prior to this point, the earliest known record of a human voice was thought to be an 1877 phonograph recording by Thomas Edison. [ 7 ] [ 14 ] The phonautograph would play a role in the development of the gramophone , whose inventor, Emile Berliner , worked with the phonautograph in the course of developing his own device.
The Victor Talking Machine Company was an American recording company and phonograph manufacturer, incorporated in 1901. Victor was an independent enterprise until 1929 when it was purchased by the Radio Corporation of America (RCA) and became the RCA Victor Division of the Radio Corporation of America until late 1968, when it was renamed RCA Records.
The LP (from long playing [2] or long play) is an analog sound storage medium, specifically a phonograph record format characterized by: a speed of 33 + 1 ⁄ 3 rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the "microgroove" groove specification; and a vinyl (a copolymer of vinyl chloride acetate) composition disk.
