Current, the crucial question that restricts development of our country electroacoustic parts of an apparatus is the special component shortage with high content of high grade science and technology, basically be the research lag of pair of special material and treatment craft. Accordingly, electroacoustic enterprise should continue to execute " on class grabs from the spare parts " guiding principle, rise and perfect the industry that with specializationing cooperation is a feature to organize a structure. Encourage conditional assembly enterprise, withhold keen-witted and capable component to develop development power, produce oneself have a part only, go after the individuation of the product. Should introduce adequately, study, use foreign loudhailer new assembly, new material, new technology, new technology, production gives high grade component; The acoustics, electricity that should involve from loudhailer, mechanical come with all aesthetic many sided integration analysis, the design makes spare parts of high quality scales; Should make spare parts enterprise pays attention to loudhailer of relevant field qualified personnel introduce, wait like major of high polymer chemistry, papermaking, quicken the class on spare parts.
