‘电铃’ literally means ‘electric bell’ — a device that produces sound when an electric current passes through it. The first character, 电 (diàn), means ‘electricity’ or ‘electric’, and the second, 铃 (líng), means ‘bell’. Together, they form a compound noun referring specifically to bells powered by electricity, commonly found in schools, offices, apartments, or door entry systems. Unlike traditional hand-rung bells or mechanical chimes, 电铃 relies on electromagnetism to vibrate a metal clapper or produce a tone electronically.

This word is neutral in register and widely used in everyday contexts — for example, to signal class changes, office break times, or door announcements. It’s not used for musical instruments or decorative bells; those are usually just 铃 or 铃铛. In modern usage, 电铃 may also refer to the electronic chime in intercoms or smart home devices, though more technical terms like 门铃 (doorbell) or 警报器 (alarm) may be preferred depending on function.
