An alarm clock was purposely designed to create an awareness of a specified time that was set earlier in the day or the previous days. They are mostly used to wake people from short naps or a night’s sleep. Other people also set an alarm to alert them of a particular schedule and it helps you be on your feet without getting late to your scheduled program. They are different types of alarm clocks that use sound while others use light or vibration. You will have to press a button or handle to stop the sound or light that comes from the alarm clock.
A day has 24 hours and we always follow a program from the time you wake up until the time you retire. The alarm clock also follows the 24 hours schedule and will ring at the exact time you set the alarm. It helps us manage our time well by keeping one focused despite all the distractions around us. There are moments when the due-list of work is so long that you are buried deep in one ask and forgetting the other. Setting an alarm can be useful when you are working on a tight schedule because you need to manage your time well.
There are many types of alarm clocks and some are also found in watches and mobile phones. Others include an analog alarm clock, digital alarm clocks, clock radios and a progressive alarm clock. The classic analog alarm clock has an inset dial or an extra hand that is used to specify the time of activating the alarm.
The traditional mechanical alarm clocks have single or dual bells that ring by the help of a mainspring. This mainspring powers a gear that propels a hammer to rock back and forth between the interior sides of a single bell or the two bells. The back encasement of the clock can also act as the bell in other models.
The electric bell-style alarm clock is mostly used in schools. It is activated at the set time by an armature which turns the circuit on and off consecutively powered by an electromagnetic circuit. The digital clock is quite different and can produce other sounds. The novelty alarm clocks can speak or play sounds of nature while the simple battery-powered alarm clocks make a beeping or buzzing sounds.
Clock radios can be set to play at different times and you will be alerted by the music that originates from the radio. A progressive alarm clock has different alarms that can be set for different times and play the music of your choice. The technology is incorporated in the modern televisions, digital watches, and mobile phones.
