sackbut

n.低音喇叭；竖琴的一种

This also is why the account that sound box of type of a few be born wants to design sackbut in upper part. 这也是为什么一些落地式音箱要把低音喇叭设计在上方的原因。

From instruments with wonderful distant names like Sackbut, xxx, shawm and xxx to 21st century computers and synthesizers. 我试试补充一下乐器名。还是有两个查不出来,我再查查。别的方面，就要请高手们斧正啦。
