• intros：{"brand_intro":"雅马哈（Yamaha）创立于1887年，最初以钢琴和管风琴制造起家，现为全球最大的乐器综合制造商。创始人山叶寅楠从修理风琴起步，奠定了\"工匠精神\"的基因。雅马哈在电子乐器领域拥有合成器、电钢琴、电子鼓等完整产品线，其数字信号处理（DSP）技术全球领先。DT-50是雅马哈针对入门级电声三角铁市场的产品，延续了品牌\"高性价比、稳定可靠\"的品控理念。雅马哈的品控体系要求每批次产品抽检率超过30%，并承诺两年质保。","product_intro":"DT-50定位为家庭练习和中小型演出用电声三角铁，价格亲民。核心卖点：采用雅马哈自研的\"动态拾音膜\"，可模拟三种经典三角铁音色（维也纳式、法式、现代式）；内置节拍器和蓝牙音频接收功能，方便练习时跟伴奏。相比罗兰RT-1000，DT-50缺少MIDI输出，但胜在操作简单、即插即用，适合初学者和音乐教师。竞品卡西欧CT-30仅支持单一音色，而DT-50的音色切换旋钮设计更人性化。","key_specs":{"拾音技术":"动态电容拾音膜，支持三种音色预设","材质":"不锈钢三角铁本体，表面镀铬处理","接口":"6.35mm输出、蓝牙5.0音频输入","电源":"内置锂电池，续航8小时","重量":"280g，轻便易携带","适用人群":"音乐爱好者、中小学音乐教师、业余乐队"}}
