• intros：{"brand_intro":"乐海品牌介绍同第一款产品，此处补充：入门教学款是乐海针对学生市场推出的高性价比产品线，延续了品牌\"专业音质平民化\"理念。该系列采用简化电路设计，但核心拾音器与高端款同源，确保音色底线。乐海在河北肃宁建有全产业链工厂，从竹材处理到电子组装一体化，成本控制能力行业领先，因此能以680元价格提供专业级拾音体验。","product_intro":"乐海LH-DB-02定位学校教学与零基础入门，核心卖点是\"即插即用\"与\"防啸叫设计\"。管体采用全ABS材质，重量仅150克，内置简易调音表与节拍器功能。相比敦煌便携款，乐海这款更注重课堂使用场景，音量旋钮带防误触设计，且提供6个月免费换新服务。竞品中，其音色纯净度与耐用性突出，但缺少蓝牙等智能功能。","key_specs":{"管体材料":"ABS工程塑料，抗摔耐造","拾音系统":"压电陶瓷（简化版），信噪比≥70dB","输出接口":"3.5mm耳机/6.35mm音频","电池续航":"AA电池×4，连续使用20小时","适用人群":"中小学生、老年大学学员、零基础爱好者"}}
