电铃

• 拼音: diàn líng
• 汉字拆解: 电 = 雨 + 申 (electricity); 铃 = 钅+ 令 (small bell, chime)

含义

Electric bell; a bell powered by electricity, typically used as a doorbell, school bell, or alarm signal.

Refers to any electrically operated bell used for signalling in schools, offices, factories, and residences. The sound of a 电铃 is often associated with institutional life — class changes, shift begins, or the ring of a doorbell. Less common in modern smart-home contexts where digital chimes are preferred.

例句

• 访客按下门廊电铃后，屋主可通过室内对讲机核实来访者身份，再决定是否开门迎客。(After a visitor presses the doorbell, the homeowner can verify the visitor's identity through the indoor intercom before deciding whether to open the door.)
