• intros：{"brand_intro":"金贝（Jinbei）是中国新兴口琴品牌，成立于2015年，专注布鲁斯（蓝调）口琴细分市场。品牌核心优势是\"免调音+蓝调音色优化\"，通过调整簧片弧度与盖板共振腔，模拟经典蓝调口琴的\"沙哑感\"。创始人李金贝是蓝调乐手，因找不到平价蓝调口琴而自主创业。金贝品控采用\"双盲测试\"，每批产品由专业乐手盲听打分，合格率仅85%。JB-16是其爆款，被乐手称为\"国产蓝调神器\"。","product_intro":"JB-16是金贝免调音布鲁斯口琴，定位蓝调爱好者与进阶玩家。核心卖点：10孔20音布鲁斯调音、磷青铜簧片（音色粗犷）、免调音设计（出厂即蓝调味）。适用场景：蓝调即兴、乡村音乐、口琴独奏。竞品对比：相比和莱Marine Band（约500元），JB-16价格更低，音色更\"脏\"（蓝调特色），但做工精细度稍差；相比东方鼎T12，JB-16的布鲁斯调音更专业，但全音阶适应性弱。","key_specs":{"簧片材质":"磷青铜，音色温暖带颗粒感","音域":"3个八度（C4-C6），20音布鲁斯调音","调音方式":"免调音，蓝调音色优化","盖板材质":"不锈钢拉丝，防锈","重量":"约160g，便携","适用人群":"蓝调爱好者、中级乐手"}}
