Abstract
A record player capable of playing phonographic records that may be played in a scratch style by a user. The record player includes a tonearm that is rotatably supported at or near an end of the tonearm by a structure having both horizontally and vertically fastening points to the tonearm. The fastening points are configured to receive a user activated tension adjustment element. A user may advance or retreat the tension adjustment element to selectably control the positioning, or relative tension in the tonearm such that any record skipping due to undesirable tonearm pressure is controlled, or to achieve a specific sound.
Claims14
A record player adapted to a scratch performance operation for outputting a sound by directly rotating a phonographic record in a forward or backward direction by a finger operation of an operator, comprising:
- a turntable driven to rotate around a first rotation core;
- a tonearm, having a first end and a second end, which is supported so as to be capable of horizontally swiveling around a rotating second rotation core positioned outside said turntable, said tonearm including a needle proximal the first end for tracking a record groove of said phonograph record as viewed from a plane;
- a sensor which is proximal the second end to detect a sound signal by said needle for tracking said record groove of said phonograph record and,
- a tonearm suspension system proximal the second end,
- wherein the tonearm suspension system includes a vertical tension control element configured to control movement of the tone arm in a vertical plane at the location of the vertical tension control element, the vertical tension control element being a center of rotation in the vertical plane for the tone arm and a horizontal tension control element configured to control movement of the tone arm in a horizontal plane at the location of the horizontal tension control element, the horizontal tension control element being a center of rotation in the horizontal plane for the tone arm.
A suspension system for a tonearm of a record player, comprising,
- a yolk configured to moveably receive an end of the tonearm;
- a vertical tension control element integral to a portion of the yolk, the vertical tension control element including a vertical bearing element and a vertical gimbal element adjacent one another, the vertical tension control element being configured to control movement of the tone arm in a vertical plane at the location of the vertical tension control element and the vertical tension control element being a center of rotation in the vertical plane for the tone arm;
- a tension adjustment system threadably engageable with the vertical gimbal element and configured to selectable engage the vertical bearing element;
- and,
- a horizontal tension control element integral to a portion of the yolk, the horizontal tension control element including a horizontal bearing element and a horizontal gimbal element adjacent one another, the horizontal tension control element being configured to control movement of the tone arm in a horizontal plane at the location of the horizontal tension control element and the horizontal tension control element being a center of rotation in the horizontal plane for the tone arm;
- and,
- a tension adjustment element threadably engageable with the gimbal element and configured to selectable engage the horizontal bearing element.
