• intros：{"brand_intro":"科宾是中国乐器配件品牌，隶属广州科宾乐器有限公司，成立于2005年。品牌主打\"高性价比\"，专注学生级与入门级琴套市场。科宾采用国产高密度牛津布与EVA泡沫内衬，成本仅为进口品牌的1/5。虽无核心技术突破，但凭借\"够用且便宜\"的策略，在国内电商平台销量领先。创始人陈科宾原是琴行老板，因客户常抱怨进口琴套太贵而创立品牌。","product_intro":"KB-600 是科宾的畅销款，定位学生与业余爱好者。核心卖点：加厚（4cm）EVA内衬、防水牛津布、可折叠设计。对比Gewa，防护性差但价格仅1/4。用户评价\"对得起价格\"，适合日常练习或短途搬运。缺点是拉链易卡顿，且背带缝线不牢。","key_specs":{"材料":"600D牛津布（防水涂层）","内衬":"4cm EVA泡沫","重量":"2.5kg","适配尺寸":"3/4 或 4/4","背负系统":"双肩背带+手提带","附加功能":"外部小物袋"}}
