• intros：{"brand_intro":"天鹅（Swan）是中国老牌口琴制造商，成立于1982年，总部位于江苏。品牌以\"全民口琴\"为理念，产品覆盖低端至中端市场，年产量超百万支。天鹅拥有多项专利，包括\"双簧片共振技术\"和\"防漏气吹嘴设计\"。其品控体系严格，每支口琴出厂前经过音准和漏气测试。创始人李工原是国营乐器厂技术员，下海后创立天鹅，坚持\"让每个中国孩子买得起口琴\"。SW系列是其半音阶口琴的入门主力。","product_intro":"SW-1248是天鹅的入门级半音阶口琴，定位学生和业余爱好者。核心卖点包括：黄铜座板（成本低）、ABS树脂琴格（防潮）、以及简易吹嘴设计。适用场景为学校音乐课、家庭娱乐和初级自学。与东方鼎T12-48相比，SW-1248价格更低，但音色偏薄，高音区易破音；与Hohner CX-12相比，其气密性和耐用性差距明显。适合预算极度有限或仅需临时使用的用户。","key_specs":{"调性":"C调（标准半音阶）","琴格材质":"ABS树脂（轻便）","簧片数量":"48个（3个八度全半音）","盖板材质":"不锈钢（薄板冲压）","适配人群":"完全初学者","重量":"约170g"}}
