隨著數(shù)字產(chǎn)品的普及，個性化的定制服務也在走向每一個普通人。打電話時，我們聽到的不再是單調(diào)的“嘟嘟”聲，而是悅耳動聽的音樂。電話簿里不同的人來電，我們聽到的電話鈴聲(ringtone)也會不同。今天，我們就來說說“彩鈴”在英文中的說法。

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)指電話處于正常使用狀態(tài)時，打電話的人從聽筒中聽到的聲音提示。這種聲音一般都是一個重復的音調(diào)，目的只是提示打電話的人，對方的電話正在接通中。

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(“個性化接通回音”)則是打電話時，傳統(tǒng)的電話提示音被音樂所取代，于是成為了我們所說的“彩鈴”。
