• intros：{"brand_intro":"金宝（Jinbao）是中国河北的管乐器制造商，成立于1998年，以\"高性价比\"著称。品牌专注于学生级与中级乐器，采用机械化生产与人工质检结合的模式，年产量超10万支。金宝的G调单簧管在国内市场占有率极高，尤其受中小学乐团欢迎。创始人王金宝原是乐器厂技工，品牌品控强调\"耐用性\"，所有乐器经过72小时连续吹奏测试。虽然技术积累不如国际大牌，但价格仅为进口品牌的1/10。","product_intro":"JB-200G是金宝G调单簧管的入门型号，定位学生与初学者。核心卖点：1）ABS树脂管体，轻便耐用（约650g）；2）17键镀镍按键，手感适中；3）附赠吹嘴、哨片与便携包。相比雅马哈YCL-650G，价格仅为1/4，但音色与做工有差距。适合预算极低但想尝试G调音色的用户，尤其适合小学乐团合奏。","key_specs":{"材质":"ABS树脂","按键系统":"镀镍镍银，17键5环","音域":"约2.5个八度（E3-B5）","吹嘴":"金宝原装吹嘴，开口0.90mm","适用人群":"初学者、小学乐团、业余爱好者"}}
