在音响装置中,磁带走速稳定与否直接关系到音质的好坏.目前国内外大多数录音机均采用电子稳速电路来保证带速的稳定,故研究简单,实用的电路,提高稳速指标很有必要. 本文通过一典型实例,提出稳速电路的简便设计计算方法.并通过调试使设计电路的稳速指标达到国家等级标准(转速误差△n<±1.5％,瞬时抖晃率△W<0.3％).所提出的设计计算方法可供设计与维修人员参考.

In the audio device, the stability of the tape is directly related to the quality of the sound quality. At present, most of the domestic and foreign recorders use electronic steady speed circuits to ensure the stability of the lead. Therefore, it is necessary to study a simple and practical circuit. It is necessary to improve the stability indicator. This article proposes the simple design calculation method of the steady -speed circuit through a typical example. Level standard (speed error △ n <± 1.5 %, instantaneous shaking rate △ w <0.3 %). The design calculation method proposed for design and maintenance personnel reference.
