Phonograph playing vehicle
10872621 · 2020-12-22 ·

A phonograph player includes a body with a motor configured to drive a drive wheel and also having a head-shell. The head-shell rotates relative to the body and holds a needle cartridge. The head-shell is also configured to activate a sensor governing motor speed. The sensor is calibrated for rotation of the head-shell to alter motor speed, and such that rotating the head-shell results in the body portion maintaining a constant RPM relative to the phonograph. The sensor may be a light sensor, and the apparatus may include a head-shell clip for holding the head-shell. Preferably, the head-shell holds the needle cartridge in a trailing configuration, and a housing at least partially cover the body.
