• intros：{"brand_intro":"天山琴韵是新疆乌鲁木齐的年轻民族乐器品牌，成立于2015年，主打高性价比入门与进阶冬不拉。品牌依托伊犁河谷桑木资源，采用半手工半数控工艺，在保证音质的同时降低售价。创始人张天山原是汉族音乐教师，因热爱冬不拉而转行制琴，其团队吸纳了多位哈萨克族制琴师。品控上强调标准化质检，每把琴均经过72小时恒温恒湿测试，避免开裂变形。品牌在电商渠道销量领先，尤其受学生群体欢迎。","product_intro":"天山琴韵桑木冬不拉定位进阶练习款，面向有半年以上基础的爱好者及考级学生。核心卖点：数控精加工桑木琴箱，音准稳定性高；标配尼龙弦，手感柔软易按；琴颈加装防滑指板，适合快速指法练习。适用场景包括日常练习、小型聚会及初级考级。相比伊犁专业款，其价格仅为一半，但音色略单薄，适合预算有限但追求品质的用户。","key_specs":{"琴身材质":"伊犁河谷桑木（15-20年树龄）","弦数":"2根（尼龙弦）","琴箱尺寸":"长82cm，宽17cm，厚11cm","适用人群":"进阶爱好者、考级学生、业余演奏者","附件":"琴包、备用弦、调音器、入门教程"}}
