• intros：{"brand_intro":"星海钢琴集团有限公司（Xinghai Piano Group）成立于1949年，是中国最早的乐器制造企业之一，原为北京钢琴厂，后拓展民族乐器业务。星海品牌以\"国民乐器\"为定位，主打高性价比普及型产品，年销量超50万件。其核心优势在于规模化生产和严格的质量管理体系（ISO14001环境认证）。创始人团队曾参与研制新中国第一架钢琴，品控理念强调\"安全、耐用、易上手\"。星海三弦是许多中小学音乐课和老年大学的标配，市场保有量极大。","product_intro":"星海XH-3X-100初学普及型大三弦定位入门市场，面向零基础学生、老年爱好者及预算有限的用户。核心卖点：采用复合板材（桐木+杨木）降低成本，但通过结构优化保证基础音准；琴杆使用桦木，轻便易握；蒙皮采用合成皮（仿蟒皮），耐用且不受温湿度影响。适用场景为音乐课堂、家庭练习、社区活动。与乐海入门款相比，星海琴更轻（约3.5kg），且价格更低（1800元），但音色质感明显逊色。竞品对比中，其最大的优势是\"皮实耐造\"，适合儿童和初学者。","key_specs":{"面板材料":"复合板材（桐木+杨木），成本低、重量轻","琴杆材料":"桦木，密度约0.65g/cm³，轻便易握","蒙皮材质":"合成皮（仿蟒蛇皮），耐候性强、无需保养","琴弦配置":"星海定制钢弦，张力低，按弦轻松","琴体总长":"约120cm，共鸣箱直径约34cm","适用人群":"零基础学生、老年爱好者、预算有限的初学者"}}
