• intros：{"brand_intro":"斯通威（Stoneway）是中国新兴管乐器品牌，成立于2015年，主打'互联网直销'模式，砍掉中间商，以低价高配策略抢占市场。品牌创始人李伟原是乐器厂工程师，后创立斯通威，专注于入门级小号。核心技术包括'数控冲压'工艺和'激光焊接'，虽非手工制作，但品控稳定。ST-2000R是其红铜入门型号，以'百元级红铜'为卖点，在电商平台销量极高。","product_intro":"ST-2000R是斯通威入门级红铜小号，定位极致性价比。核心卖点：红铜喇叭口（直径4.7英寸），音色略暖于黄铜；不锈钢活塞，顺滑度尚可；镀铬表面，耐磨易清洁。适用场景：初学者练习、业余娱乐。相比杰普特JTR-700R，ST-2000R价格更低（约3200元），但红铜材质更薄，音色差异不明显。适合预算极低、仅想体验红铜外观的用户。","key_specs":{"喇叭口材质":"红铜，直径4.7英寸，音色略暖","管体材质":"黄铜，镀铬表面","活塞系统":"不锈钢活塞，顺滑度一般","吹口管":"标准锥度，固定式","调音管":"第一调音管带拇指钩","适配人群":"预算极低的初学者、儿童、业余爱好者"}}
