Abstract
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.
Claims20
A phonograph player for playing a phonograph having a groove, the player comprising:
- a body portion coupled to a motor, the motor configured to drive a drive wheel;
- the body portion further coupled to a head-shell;
- the head-shell rotatable relative to the body portion and configured to hold a needle cartridge, thereby allowing the needle cartridge to rotate relative to the body portion;
- the head-shell configured to activate a variable sensor, the variable sensor configured to govern a speed of the motor;
- the variable sensor calibrated such that rotation of the head-shell results in altering the speed of the motor;
- and
- wherein the sensor is further calibrated such that rotation of the head-shell as the needle cartridge follows the groove on the phonograph results in the drive wheel maintaining the body portion at a constant RPM relative to the phonograph.
A phonograph player for playing a phonograph having a groove, the player comprising:
- a body portion having a battery, a motor and a drive wheel;
- a head-shell clip coupled to the body portion, the head-shell clip rotatable relative to the body portion and configured to hold a head-shell, thereby allowing the head-shell to rotate relative to the body portion;
- a light emitter and a sensor located on opposing sides of a light slot;
- the head-shell clip having an angled block for gradually obscuring the light slot;
- the sensor calibrated such that rotation of the head-shell clip results in altering the speed of the motor;
- and
- wherein the sensor is further calibrated such that rotation of the head-shell clip as the phonograph player follows the groove on the phonograph results in the drive wheel maintaining the body portion at a constant RPM relative to the phonograph.

- a light emitter and a sensor located on opposing sides of a light slot;
- the head-shell clip having an angled block for gradually obscuring the light slot;
- a head shell wheel anchored between a head-shell guide and a head-shell wheel guide, the head-shell held firm and configured to move with the head-shell clip as it rotates;
- the sensor calibrated such that rotation of the head-shell clip results in altering the speed of the motor;
- and
- wherein the sensor is further calibrated such that rotation of the head-shell clip as the phonograph player follows the groove on the phonograph results in the drive wheel maintaining the body portion at a constant RPM relative to the phonograph.
