• intros：{"brand_intro":"威音是中国本土乐器配件品牌，成立于2005年广东汕头，专注中低端市场。品牌以\"高性价比\"著称，采用非洲进口乌木与国产精密五金件，成本控制能力极强。创始人陈伟明原是提琴厂工人，因发现进口尾绳价格虚高而创业。品控上，威音实行\"全检制度\"，每根尾绳出厂前需经过拉力测试和音色试听。目前是国内中小学乐团、琴行渠道的销量冠军，市场份额占国内中提琴尾绳市场的35%。","product_intro":"WY-VT2023 定位入门级教学用尾绳，主打\"耐用与稳定\"。核心卖点：整块乌木雕刻成型，无拼接，减少开裂风险；标配4颗黄铜微调螺丝，防锈处理；表面手工打磨至800目，触感细腻。适用场景：学生练习、业余考级、乐团合奏。竞品对比：相比进口品牌（如Pirastro），价格仅为1/3，但音色厚度和微调精度稍逊；相比同价位国产竞品（如金音），乌木密度更高，寿命长2年。","key_specs":{"材料":"非洲乌木（整块雕刻）","重量":"18克（含微调）","适配琴型":"14-16英寸中提琴","微调系统":"4颗黄铜微调，防锈镀层","表面处理":"手工打磨至800目，哑光","适用琴弦":"尼龙弦/钢弦通用"}}
