本文第一部分已经讨论了唱机重放过程中必须考虑的几个主要因素。我们将这些因素分成两类,即在理想条件下和音槽调制放音有关的因素;放音时产生实际问题的因素。阐述在理想条件下拾音头性能的技术规范,包括频率响应、分离度、循迹能力和失真。实际问题主要有调制电平太高、唱片翘曲、结构噪声、拾音头——音臂谐振、静电、唱片和唱针上污物的积聚。所有这些问题都会对音质产生严重的和决定性的不良影响。拾音头的设计目标有两个。首先,必须使之在理想条件下具有最大的放音能力。这 The first part of this article has discussed several key factors that must be considered in the playback of a phono player. We classify these factors into two categories, namely, the factors that are related to the sound modulation of the sound tank under ideal conditions and the factors that cause actual problems when sound is released. Describe the specifications for pickup performance under ideal conditions, including frequency response, resolution, tracking capability, and distortion. The actual problems are mainly the modulation level is too high, the record warpage, structure noise, pick-up head - acoustic arm resonance, static electricity, record and stylus on the accumulation of dirt. All of these issues have a serious and decisive adverse effect on sound quality. Pickup head design goals have two. First of all, you have to have the maximum playback capability under ideal conditions. This
