• intros：{"brand_intro":"Wittner 是德国专业弦乐器配件品牌，成立于1895年，以生产拉弦板、弦锁、腮托等精密五金件闻名。品牌核心优势在于航空级铝合金加工技术，产品重量仅为传统黄铜件的1/3。创始人Wilhelm Wittner原是钟表匠，将钟表齿轮工艺引入弦锁制造，实现了0.01mm级调音精度。品控理念强调\"每个零件需通过2000次疲劳测试\"，是众多制琴师的首选配件品牌。","product_intro":"此款为独立弦锁配件，非琴弦套装，可替换原装拉弦板。核心卖点：采用7075航空铝合金，重量仅12克（传统黄铜件约35克），能显著提升琴体共振。内置4个独立微调旋钮，支持每根弦独立调音。适用场景：对音色灵敏度有极致要求的专业演奏者，或老旧琴需减重升级。竞品对比：比Böhm同类产品轻20%，且耐腐蚀性更强。","key_specs":{"主体材质":"7075航空铝合金，强度高且耐腐蚀","重量":"12克（含4个微调旋钮）","微调精度":"0.01mm/格，支持双向调节","适配琴型":"4/4标准小提琴，兼容多数拉弦板接口","表面处理":"阳极氧化黑色/银色，防刮耐磨"}}
