嗨,大家好。在这个项目中我还是个新手。我想让我的da14580-dev套件B使用扬声器或蜂鸣器播放声音。有人能帮我吗?< / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords /声音”“=“skos:概念”属性=“rdfs: label skos: prefLabel”声音数据类型= " " > < / > < / div > < div class = " field-item古怪”> < a href = " / resource-keywords / da14580”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > da14580 < / > < / div > < div class =”field-item甚至“> < a href = " / resource-keywords /扬声器”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >议长< / > < / div > < div类= " field-item奇怪" > < a href = " / resource-keywords /噪音”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >噪音< / > < / div > < div class =”field-item甚至“> < a href = " / resource-keywords /音乐”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >音乐< / > < / div > < / div > < / div > < div class = "字段field-name-field-device
