In a phonograph, a device containing a sounding diaphragm and the needle or stylus that traverses the moving record, for reproducing the sound.

Also called the "Sound Box", this is the device that, well, "reproduces" the sound waves from the physical grooves in the recording media. A steel needle or gem stylus vibrates in the groove and this vibration is transferred to a diaphram (paper, mica, glass, etc.) that creates sound waves. On a disk machine, these waves then travel down the tone arm to the horn where the sound eminates. On a cylinder machine, the horn is usually mounted directly on the reproducer.
