If Amazon’s alarm clock isn’t your cup of tea, however, then there’s probably another cutting-edge device for you. Light sleepers may require a little background noise throughout the evening, while deep sleepers need louder alarms to wake them in the morning. There are even alarm clocks that utilize lighting technology instead of traditional alarm functions, thus allowing for a steady, gradual sunrise in your bedroom. People are finicky about their sleeping gadgets, but, fortunately, one of these alarm clocks can probably match your lifestyle and budget. And who knows? You just might finally become a morning person.
In a master clock system, electricity is used to give direct impulses to the pendulum, which in turn causes the clock’s gear train to move, or to lift a lever after it has imparted an impulse to the pendulum. In various modern master clocks the pendulum operates a light count wheel that turns through the pitch of one tooth every double swing and is arranged to release a lever every half minute. This lever gives an impulse to the pendulum and is then restored to its original position by an electromagnet. The pulse of current that operates the electromagnet can also be transmitted to a series of distant dials, or slave clocks, advancing the hands of each through the space of a half minute. Thus, a master clock can control scores of dials in a large group of buildings, as well as such other apparatus as time recorders and sirens.

The primary purpose of a clock is to display the time. Clocks may also have the facility to make a loud alert signal at a specified time, typically to waken a sleeper at a preset time; they are referred to as alarm clocks. The alarm may start at a low volume and become louder, or have the facility to be switched off for a few minutes then resume. Alarm clocks with visible indicators are sometimes used to indicate to children too young to read the time that the time for sleep has finished; they are sometimes called training clocks.

The pendulum is a reliable time measurer because, for small arcs, the time required for a complete swing (period) depends only on the length of the pendulum and is almost independent of the extent of the arc. The length of a pendulum with a period of one second is about 39 inches (990 mm), and an increase in length of 0.001 inch (0.025 mm) will make the clock lose about one second per day. Altering the length of a pendulum is therefore a sensitive means of regulation. The alteration is usually carried out by allowing the bob to rest upon a nut that can be screwed up or down the pendulum rod.
For convenience, distance, telephony or blindness, auditory clocks present the time as sounds. The sound is either spoken natural language, (e.g. "The time is twelve thirty-five"), or as auditory codes (e.g. number of sequential bell rings on the hour represents the number of the hour like the bell, Big Ben). Most telecommunication companies also provide a speaking clock service as well.

“The alarm is loud with a lower frequency melody which I like since I have high-frequency hearing loss. Guaranteed to wake anyone up when the alarm goes off which is super important to me, especially if I’m using the alarm clock to wake up to catch a flight. … When the alarm goes off, press the large snooze bar on the top to have the alarm go off again in five minutes. Pressing the snooze bar on top at anytime also lights up the numbers and bars on the clock’s face, but the hands are a bit hard to see in the dark since the hands don’t light up. When the alarm on/off switch is turned to the off position, there’s a cute voice that says ‘Good Morning!’ which brings a smile to start the day. We love this clock so much, we plan to buy more to give as gifts. We’re sure the recipients will love it as much as we do.”
