本文从定轴转动唱臂工作中存在的循迹误差出发,讨论了循迹误差角对唱片放音的影响。定量地分析了由于误差角的存在所引起的非线性失真,并在这基础上讨论了从减小这一失真影响出发的音臂传统设计方法。文中对许多资料在各种不同情况下给出的设计公式作了详细的分析推导。文未列举了设计实例。本文对从事唱机生产、设计的工程技术人员有一定的参考价值。
This paper starts with the tracking errors existing in the work of turning the arm of the fixed axis, and discusses the influence of tracking error angle on the release of the record. The nonlinear distortion caused by the existence of the error angle is quantitatively analyzed. On this basis, the traditional design method of the arm of the sound arm, which is based on the reduction of the distortion, is discussed. The article gives a detailed analysis and derivation of the design formulas given in many different situations. The text does not list the design examples. This article engaged in record player production, design of engineering and technical personnel have some reference value.
