Abstract

The invention relates to a stylus arm of a single-point type opposite-pole magnetic-balance phonograph, belonging to the field of phonographs. The stylus arm of the single-point type opposite-pole magnetic-balance phonograph comprises a supporting arm assembly, a magnetic regulating assembly and a supporting part, wherein a centre shaft of the supporting arm assembly is provided with a drill pad; a tone arm weight is arranged on a seat casing; an oil bottle is arranged at the upper end of the centre shaft and is internally provided with a steel ring; the seat casing is arranged on a crown drill cover; the center of the crown drill cover is provided with an ultrahard drill stem; the top end of the ultrahard drill stem abuts against the drill pad; the seat casing is provided with a magnet A; the magnetic regulating assembly comprises a knob, a magnetic regulating casing, a movable bearing bracket, a bearing and a magnet B, wherein the movable bearing bracket is arranged on the centre shaft of the supporting arm assembly through the bearing, the magnetic regulating casing is internally provided with a screw on which a nut is arranged, and the magnet B is arranged on the nut. The invention has reasonable design, magnetic levitation action generation and stable equilibrium and achieves the effect of the adjustment level of a tracking acoustical pickup and a record audio track.

Description

technical field [0001] The invention relates to a stylus arm of a single-point pair magnetically balanced record player, belonging to the field of record players, in particular to a stylus arm of a single-point record player. Background technique [0002] The record player uses the stylus on the stylus arm to rub against the record to produce sound. The record is placed on the turntable of the record player. The shaking and balance of the stylus arm will be expressed through the sound played. Most of the existing technology is to improve the processing accuracy. , or install and cooperate with precision to improve the playback sound of the record player, but due to structural limitations, noise and distortion are unavoidable. Contents of the invention [0003] The object of the present invention is to avoid the deficiencies of the prior art, and provide a multi-angle adjustable, stable balance, high sensitivity, reduce resonance, avoid noise and distortion of the played so...
