学校铃声, 校钟
a mechanical or electronic device used to signal the start and end of classes or periods in a school day
A school bell is a device used to signal the start or end of classes, breaks, or other scheduled activities in a school. It is often placed in a central location, such as near the office or in hallways, to be heard by all students and staff. When rung, the bell alerts everyone to follow the school’s timetable, such as transitioning from one class to another or signaling the beginning or end of the school day. School bells are typically loud enough to be heard throughout the building or campus.
