    Phonograph in the cast metal case of complex shape of dark red color with artistic frames on the top and side surfaces is installed on a varnished wooden base. A button that switches the mechanism and a crank with the black handle for the spring winding are on the right hand side. The golden colour inscription “Edison” is transferred on the front side. Two cast supports, cylinder and carriage with the sound box drive mechanisms are on the top panel.

    The carriage, limiting the load on the cylinder rests on the vertical cast bar in front of the cylinder. The brand name is on the bar. The handwritten inscription is on the left. An oval aperture with a gearshift lever for playing 2-minutes or 4-minutes cylinders is in front of it. The screw head and handwritten inscription are on the left. A rubber tube with conical horn connects the sound box with diaphragm and stylus. Rotary mechanism is mounted on the diaphragm surface - the turret with two styluses for playing 2-minutes and 4-minutes cylinders. Stylized image of a horn with a trademark and a loop with a chain for hanging on the bracket are on the horn upper part. The shaft is connected to the spring motor through the transmission mechanism. A nameplate with the inscriptions is on the rear panel. When the mechanism is turned on, the cylinder rotates, the carriage with the sound box moves along the shaft axis. The stylus, put in the groove, causes the membrane to vibrate in time with the profile of the groove, the vibrations are amplified by the horn, and the phonograph reproduces the recorded sound. Music media: phonograph cylinder.
