17. 号角扬声器
号角的主要目的是提升扬声器辐射效率,同时控制指向性
有些翻译为号筒
"号角扬声器"直接翻译成英文为 "Horn loudspeaker",它是一种扬声器设计,主要用于提高声音的效率和方向性。号角扬声器利用一个声音导向器(或称为号角),将声音从一个小空间扩散到一个大空间。该设计已经存在已久,广泛用于各种公共地址系统,例如在体育场馆、大型活动和紧急警告系统中。号角扬声器的主要优点是其高效率和方向性。由于号角的设计,声音能够更好地集中并向特定的方向发送,使其在远距离上保持清晰度。![](https://public.fangzhenxiu.com/fixComment/commentContent/imgs/1691254888071_on746q.jpg?imageView2/0)
