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.
