• intros：{"brand_intro":"金音（Jinyin）是中国知名管乐器品牌，成立于1984年，总部位于河北衡水。作为国内最早生产小号的企业之一，金音以\"高性价比\"和\"本土化服务\"著称，产品远销欧美。品牌拥有自主研发的活塞镀铬工艺，在耐久性上媲美进口品牌。金音的品控理念强调\"让每个中国孩子买得起好乐器\"，通过规模化生产降低成本，同时保持音准合格率在98%以上。创始人张金生原是衡水乐器厂技工，后下海创办金音，被誉为\"中国小号之父\"。","product_intro":"JYTR-200是金音学生小号的主力型号，定位为预算有限的初学者及学校批量采购。核心卖点：全黄铜材质，音色厚实；不锈钢活塞，耐腐蚀且顺滑；配备可调节指环，适应不同手型。相比雅马哈YTR-2330，JYTR-200价格低近40%，但音色略偏暗，高音区阻力稍大。适用场景：学校音乐课、业余考级、社区乐团。附赠硬质号箱和清洁布，性价比突出。","key_specs":{"材质":"全黄铜（管体及喇叭口）","重量":"约1.3kg","管径":"11.73mm（标准管径）","喇叭口直径":"125mm","表面处理":"金漆或镀银可选","适配人群":"预算有限的初学者、学校乐团批量采购"}}
