n.低音喇叭；豎琴的一種

This also is why the account that sound box of type of a few be born wants to design sackbut in upper part. 這也是為什么一些落地式音箱要把低音喇叭設(shè)計(jì)在上方的原因。

From instruments with wonderful distant names like Sackbut, xxx, shawm and xxx to 21st century computers and synthesizers. 我試試補(bǔ)充一下樂(lè)器名。還是有兩個(gè)查不出來(lái),我再查查。別的方面，就要請(qǐng)高手們斧正啦。
