英语自学网

　　A ringback tone is an audible indication that is heard on the telephone
line by the caller while the phone they called is still in use. It is normally a
repeated tone, designed to assure the calling party that the called party's line
is ringing.
        　　Ringback
tone(接通回音)指电话处于正常使用状态时，打电话的人从听筒中听到的声音提示。这种声音一般都是一个重复的音调，目的只是提示打电话的人，对方的电话正在接通中。
        　　Ringback music, also called personalized ringback tone, is a piece of music
heard by the caller instead of the traditional telephone ring signal when a
telephone call is placed.
        　　Ringback music(“个性化接通回音”)则是打电话时，传统的电话提示音被音乐所取代，于是成为了我们所说的“彩铃”。
