alarm clock
An alarm clock or alarm clock is a clock that makes a sound ring at a person's specified date and time. These clocks are mainly intended for people to wake up in the morning to start the day. Sometimes it is also used to announce the schedule. To stop the sound, press the buttons or knobs around the clock, and if you keep any clocks still, the sound stops after a few minutes. Traditional analog alarm clocks have special clock hands that specify the time. The traditional alarm clock has two pieces of paper on the watch, but the digital alarm clock sounds different. The alarm clock, which simply returns to the battery, sounds loud enough to wake you up, while the new alarm clock speaks, laughs, and sings. An alarm clock called clock radio has a radio that makes radio broadcasts at set times.
