Columbia Grafonola

The Columbia Grafonola is a brand of early 20th century American phonograph made by the Columbia Graphophone Company. Introduced in 1907, Grafonolas are internal horn alternatives to the same company's external horn Disc Graphophones.[1][2]

Until late 1925, all record players reproduced sound by purely mechanical means and relied on a so-called "amplifying" horn to efficiently couple the vibrations of the stylus and diaphragm to the space occupied by the listeners. In 1906, the Victor Talking Machine Company, Columbia's arch competitor, introduced a line of models in which the horn and other hardware were concealed within a cabinet made to look like fine furniture rather than a mechanical device. They named the new style a "Victrola". It quickly proved to be very popular and successful. Other makers, adopting the distinctive suffix, introduced their own "-ola" internal horn machines, such as Edison's Amberolas and Columbia's Grafonolas. They were soon outselling the external horn models.[3]

At first, like nearly all other early record players, all Grafonolas were driven by a spring motor that the user had to wind up with a crank before playing a record or two. In 1915, Columbia began to introduce electric-motor-driven models, as a majority of urban areas had been wired to electrical grids. The electrified Grafonolas supported both alternating and direct currents from 110 to 220 volts. Electrified Grafonolas never gained the popularity enjoyed by the spring-motor-driven versions due to substantially higher prices and lack of electrical service in rural areas.[4]
