• intros：{"brand_intro":"星海（Xinghai）是中国老牌乐器品牌，成立于1949年，总部位于北京。前身为新中国第一家乐器厂，曾为人民大会堂定制乐器。星海以'让音乐走进千家万户'为使命，产品涵盖钢琴、管乐、弦乐等。其大号硬箱由北京工厂生产，采用国产ABS塑料和珍珠棉内衬，主打经济实惠。星海品控稳定，通过ISO 14001环境认证，在三四线城市和学校市场占有率极高。品牌历史悠久，承载几代音乐人的记忆。","product_intro":"星海XH-TC01大号硬箱定位入门级市场，专为学生和业余爱好者设计。外壳采用国产ABS塑料，内部珍珠棉衬垫，适配4/4大号。核心卖点：超低价、轻量（约5.8kg）、简易锁扣。适用于学校存放、家庭练习和短途搬运。相比沃克，星海价格更低但防护性更差；相比杂牌箱，星海做工规范，售后有保障。是预算极度有限用户的入门选择。","key_specs":{"外壳材料":"国产ABS塑料，抗冲击性一般","内部衬垫":"珍珠棉，防震效果中等","重量":"约5.8kg，最轻之一","适配尺寸":"兼容4/4大号，内部空间较大","锁扣":"单塑料锁扣，易损坏","防水等级":"无防水设计"}}
