One of the hardest things to do in the morning, especially after a goodnight's sleep, is waking up-which oftentimes lead to tardiness at work or in school. This is primarily the reason behind the invention of alarm clocks. These devices today come in a variety of kinds and models that range from analogue designs to radio alarm clocks.
To awaken people from sleep is the primary function of alarm clocks. Nonetheless, they are also used today to remind users of a task to be done or an occasion that needs to be attended to. These purposes are served by alarm clocks by creating a loud, often annoying, sound at the preset time of the user. To stop the noise, some alarm clocks require to be held on the handle, while other types are designed to stop after a few moments if unattended, and then ring again after a given time.
It was in 250 BC when the Greeks invented the first alarm clock called the "water clock". This alarm was made from a mechanical bird that is placed near a river. The bird releases a loud whistling sound when the rising water in the river reaches a certain preset point. Among the notable people who used this clock was Greek philosopher Plato who utilized the clock as a signal of the beginning of his lectures at dawn. Over time, various additions were incorporated to the water clock to improve its functionality. Among these, noteworthy are the elaborate systems as well as the dial and pointer time added by Hellenistic engineer and inventor Ctesibius to the clock. The improved clock of Ctesibius is also the precursor of today's modern alarm clocks. Today, alarm clocks come in a variety of types with radio alarm clocks among the most popular.
The market today is encumbered with a variety of types of alarm clocks. Three of the major types of alarm clocks commonly used today are cellphone alarm clocks, radio alarm clocks, and atomic alarm clocks. A cellphone alarm clock is a built-in function of a mobile phone. With mobile phones among the most important gadgets today, cellphone alarm clocks are also among the most used types of alarms. With the various functionalities of mobile phone, cellphone alarms can be programmed with various noises and funny sounds to signal the user's preset time.
Just like analogue alarm clocks, radio alarm clocks on the other hand are designed with modern radio technology to signal a preset time. Nonetheless, modern radio alarm clocks also feature other information such as date and temperature, radio, CD player, and a host of other functions depending on the clock's model and brand. With such added functionalities, the user is given the option to choose the way the clock would alarm at the setup time. Lastly are atomic alarm clocks. These clocks are controlled by a satellite to signal the time setup by the user.
It seems impossible to try to get by without having one to help you wake up in the morning to get to the office or to school on time these days as the modern world depends too much on alarm clocks. No matter what your preference may be, may it be a radio alarm clock or an atomic alarm clock, there will always be one for you.
