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.

Electric arm lifting and turntable's auto-stop assembly of record player
09997175 · 2018-06-12 · ·

An electric arm lifting and turntable's auto-stop assembly of a record player is revealed. A record player is disposed with a power-driven turntable, a rotatable and movable arm disposed on one side of the turntable, a lift mechanism used for pushing against and moving the arm upward, and a sensor. The arm is moveable over the turntable. The sensor is arranged at an arm rotating shaft of the arm and used for sending a signal while detecting that the arm is moved to a lift point over the turntable. The lift mechanism is activated to move the arm upward and the turntable is stopped simultaneously for protecting a needle on the arm while the sensor detects that the arm has been moved from the turntable to the lift point.

SYSTEMS AND METHODS FOR REDUCING AUDIO DISTORTION DURING PLAYBACK OF PHONOGRAPH RECORDS USING MULTIPLE TONEARM GEOMETRIES
20170256281 · 2017-09-07 ·

Systems and methods are disclosed relating to electro-mechanical devices and related computer control and audio processing systems intended to optimize playback fidelity of phonograph records. Said recordings are manufactured by a process that employs a cutting head assembly driven in a straight path from the outer to the inner-most radius of the recordable surface. However, most record turntables device that are used to play back phonograph records rely on a stylus transducer attached to the end of a pivoting arm. Instead of the linear path followed by the original cutting head, said tonearm traces an arc across the surface of the recorded disk resulting in playback distortion proportional to error in alignment of said stylus relative to the tangent of the groove. This invention addresses this deficiency and produces an optimal audio quality of playback of phonograph records.
