• intros：{"brand_intro":"Larsen 成立于1950年的丹麦，最初以制作大提琴琴弦闻名，后拓展至低音提琴配件。品牌以\"北欧极简工艺\"著称，核心优势在于使用航空级铝合金与碳纤维复合材料，大幅降低螺丝重量（仅8g）。创始人 Hans Larsen 是一位机械工程师，他将精密轴承制造技术引入琴弓螺丝领域，首创\"自润滑螺纹\"设计。品控理念强调\"轻量化与强度平衡\"，所有产品均通过-20℃至50℃环境测试。","product_intro":"Larsen 低音提琴琴弓螺丝定位中高端市场，主打轻量化与防滑性能。核心卖点是其阳极氧化铝材质与特氟龙涂层，旋入时阻力极小，且不会刮伤弓尾库木材。适用于4/4低音提琴弓，尤其受女性演奏者欢迎（重量仅为传统黄铜螺丝的60%）。与Pirastro相比，Larsen 更注重减重与手感，但极端湿度下螺纹寿命略短。","key_specs":{"材质":"7075航空铝合金+特氟龙涂层","螺纹规格":"M6×0.8mm 自润滑螺纹","适配弓型":"4/4低音提琴弓","表面处理":"阳极氧化+特氟龙","重量":"约8g","产地":"丹麦"}}
