• intros：{"brand_intro":"东方鼎（East Top）是中国本土高端口琴品牌，成立于2008年，总部位于江苏。品牌专注于半音阶口琴和布鲁斯口琴的研发，拥有多项簧片热处理专利技术。创始人张东升原为乐器厂技术员，因不满国产口琴品质而创立品牌，提出\"让世界听见中国音色\"的愿景。东方鼎在品控上对标日本铃木和德国和莱，但价格仅为进口品牌的1/3，被用户称为\"国产半音阶之光\"。","product_intro":"ET-12-48C是东方鼎的旗舰级半音阶口琴，定位进阶演奏者和专业乐手。核心卖点：12孔48音全半音阶覆盖，可演奏任意调式；专利\"双簧片独立调音\"技术，确保每个音精准；树脂琴体搭配不锈钢盖板，防冷凝且手感温润。相比同价位进口产品（如和莱CX-12），东方鼎在音色厚度和动态范围上更胜一筹，尤其适合爵士、古典和流行乐演奏。","key_specs":{"孔数":"12孔，48音（含升降半音），覆盖4个八度","调性":"C调，通过按键切换半音","材质":"树脂琴体+不锈钢盖板+铍铜合金簧片","重量":"约160g，略重于复音口琴","适用人群":"进阶演奏者、专业乐手、考级学生"}}
