在工作重点转移的新形势下,我厂为使手风琴的生产逐步实现标准化、通用化、系列化,改变过去的对号入座的装配工艺等问题,在近几年设计70贝司手风琴的基础上,吸取国内外样机的优点,进行了多次研究试验,自行设计了整体结构贝司机。制品经过两年多的试奏,证明机械性能稳定,噪音小,灵敏度较高。 Under the new situation of shift of work emphasis, in order to gradually standardize, generalize and serialize the production of accordion, and to change the past assembly process of condemnation, we draw on the basis of the design of 70 bass accordion in recent years. The advantages of prototype at home and abroad, conducted a number of research experiments, designed their own overall structure of the bass machine. After more than two years of trial products, mechanical stability, low noise, high sensitivity.
