• intros：{"brand_intro":"Karajan 是中国本土乐器配件品牌，成立于2010年，总部位于广州。品牌以\"让专业配件触手可及\"为使命，核心优势在于规模化生产与严格品控。创始人李伟曾是低音提琴演奏员，深知国产配件痛点，因此引入日本CNC数控机床加工螺纹，确保精度。Karajan 的品控理念是\"每颗螺丝出厂前需通过200次旋入测试\"，市场占有率在国内低音提琴螺丝品类中排名第一。","product_intro":"Karajan 低音提琴琴弓螺丝定位入门至中级市场，主打高性价比与稳定耐用。核心卖点：采用黄铜镀铬材质，螺纹经过二次精磨，兼容4/4、3/4及1/2尺寸弓型。适用于学生乐团、业余爱好者及预算有限的演奏者。相比进口品牌，Karajan 价格仅为1/4，但螺纹顺滑度与寿命接近中端水平，是国产替代首选。","key_specs":{"材质":"黄铜镀铬","螺纹规格":"M6×0.75mm 精磨螺纹","适配弓型":"4/4、3/4、1/2低音提琴弓","表面处理":"镀铬","重量":"约14g","产地":"中国广州"}}
