When you set an alarm on a digital clock, a signal is sent to activate the alarm when the correct time is reached. This signal of one hertz is then used to drive the clock's timekeeping mechanism.Īs the clock receives the correct number of signals to pass either a second, minute or hour, signals are sent to an electronic chip that converts the time into a display on the clock's screen. After the clock receives this signal, it is converted to a new signal of exactly one hertz (one signal per second). This oscillator sends a regular fast repeating signal to a receiver within the clock's circuitry. This is normally powered by either mains electricity, a battery, or kinetic energy. The clock mechanismĭigital clocks usually use a quartz crystal oscillator to keep time. While some people may be familiar with the fact that analog clocks have gears that turn the hands and keep time, fewer people are familiar with how digital clocks work. This allows the alarm mechanism to activate and rattles the hammer between the bells. However, when the alarm is switched on, the spring is released when the clock's hour hand reaches the position of the alarm hand. When the alarm is not in use, a spring prevents this mechanism from activating. Within the analog clock is a mechanism that causes the hammer to rattle between the bells. Often smaller and a different color, this hand is there to set the time for the alarm. On the front of an analog clock, there is a hand that is different from the other hands of the clock. Nowadays, many analog clocks are powered by electricity and work like digital clocks. These kept the time accurate by regulating the speed of movement of the gears. Attached to the gear mechanism was an escapement wheel and an oscillator. Inside the mechanism was a spring which, when it was wound up, slowly released itself to power the gears. Traditionally, analog clocks called wind-up alarm clocks were powered by being wound up. Inside an analog clock is a set of gears that move the hands of the clock around. On top of the clock are two bells with a hammer between them that goes back and forth when it's time to wake up. The clockface sits on small legs, usually on the bedside table.
