• intros：{"brand_intro":"卡马是中国乐器品牌的后起之秀，成立于2009年，以\"让音乐触手可及\"为理念。品牌早期专注于吉他制造，后拓展至打击乐器领域。卡马拥有全自动数控生产线，品控严格遵循ISO 9001体系，其沙锤产品以\"高性价比\"著称。创始人张先生原是吉他教师，因发现学生买不起进口沙锤而决定自主研发，坚持\"同等品质，价格减半\"的定价策略。","product_intro":"KM-500是卡马的旗舰沙锤，定位预算有限的舞台表演者。核心卖点：外壳采用高密度桦木（多层压合），音色接近天然木质感；内部填充钢珠+塑料珠混合，兼顾清脆与柔和；手柄采用人体工学曲线设计，握持舒适。适用于校园演出、社区活动、乐队排练等场景。相比敦煌，卡马音色更现代；相比进口品牌，价格仅为1/3-1/4，但做工精细度稍逊。","key_specs":{"外壳材质":"多层桦木（高压压合）","填充物":"钢珠+塑料珠混合（比例3:2）","手柄材质":"桦木+哑光漆面","重量":"单只约150g","适用人群":"学生乐队、业余爱好者、预算有限的舞台乐手","产地":"中国广东"}}
