• intros：{"brand_intro":"Wittner 成立于1895年德国，是历史悠久的乐器配件品牌，以\"精准机械\"著称。创始人Carl Wittner原是钟表匠，将精密齿轮工艺引入弦乐器配件。品牌核心优势在于\"模块化设计\"，所有配件可互换升级。Wittner尾绳采用尼龙与黄铜组合，品控通过ISO 9001认证，是入门到中级市场的销量冠军，全球年销量超50万套。","product_intro":"Wittner Ultra系列尾绳定位\"高性价比全能款\"，采用尼龙纤维与黄铜调节螺丝，支持微调长度（±5mm）。核心卖点是\"免工具安装\"，适合学生和业余爱好者。适用于日常练习、考级及小型演出。相比Pirastro和Larsen，Wittner音色中性均衡，缺点是高端声学性能不足，但价格仅为前两者的一半。","key_specs":{"材料":"尼龙纤维 + 黄铜调节件","长度":"可调范围 260-280mm（适配4/4）","重量":"15g（标准重量）","适配琴型":"4/4大提琴（3/4/1/2/1/4可选）","张力等级":"可调（通过螺丝调节）","声学特性":"中性音色，无明显染色"}}
