1974年我厂开始研制电影同步录音机用扬声器。电影同步录音机是我国赶超世界先进水平的新产品,所用扬声器也应赶超世界先进水平。我们根据电影同步录音机的技术要求,在四机部和省市领导的关怀下,在厂党委和革委会的直接领导下,经过全厂职工
In 1974, our factory started to develop loudspeaker for movie synchronous recorder. Film synchronous recorder is our country to catch up with the world’s advanced level of new products, the speakers should also catch up with the world advanced level. We are based on the technical requirements of the film synchronous recorder, with the care of the four machine department and provincial leaders, under the direct leadership of the Factory Party Committee and the Revolutionary Committee, after all plant workers
