• intros：{"brand_intro":"天鹅是中国老牌口琴制造商，成立于1980年，总部位于上海。品牌曾为多家国际品牌代工，积累了丰富的制造经验。天鹅在2010年后转型自主品牌，主打中低价位市场。SW-1248是其首款可替换簧片半音阶口琴，旨在用亲民价格普及可维护设计。天鹅的品控理念强调\"稳定压倒一切\"，虽然创新速度不及新兴品牌，但产品故障率较低。品牌在二三线城市及老年乐手中拥有较高知名度，被誉为\"口琴界的永久自行车\"。","product_intro":"SW-1248是天鹅的中端半音阶口琴，定位家庭娱乐与社区乐团。核心卖点是\"低价半音阶+可换簧片\"，填补了300元价位段的空白。琴身采用不锈钢盖板与铜合金簧片，音色偏温暖，适合演奏经典老歌与民歌。与东方鼎T008S相比，SW-1248为半音阶结构，音域更广，但做工精细度略逊。标配12孔48音，附赠简易收纳盒与替换簧片工具。适合预算有限但希望体验半音阶口琴的业余爱好者。","key_specs":{"簧片材质":"铜合金，耐用性一般","盖板材质":"不锈钢，防锈性能好","琴格材质":"铜合金，重量较大","调性":"C调","孔数":"48孔（半音阶）","适配人群":"业余爱好者、中老年乐手"}}
