Things to Consider Before Buying Clock Radio!

Display

There are several characteristics of the display that must be considered when choosing a clock radio: in recent years, various measures have been developed designed to improve not only the quality of the display but also the user’s rest. Let’s see in detail all the most important features of the display of a clock radio. Clock radio display

Dimensions 

Radio alarm clocks can always boast large screens, especially when compared to classic analog alarm clocks. However, there are many different designs, some of which have a very small display, which instead leaves the room.

For example, for a larger speaker or other additional elements that can increase the number of functions offered by the device. For those looking for clock radio with a visible display, it is advisable to focus on a model that reaches at least three inches diagonally.

Brightness 

This is one of the most relevant aspects by far for many users, given that the clock radio must usually be placed on the bedside table, very close to those who sleep.

Those who are particularly sensitive to light during sleep can now look for a model that allows automatic or manual brightness adjustment. Some products offer different preset levels, even going as far as to completely deactivate the display during the night, to guarantee a better rest.

Panel Construction Technology

From this point of view, we certainly do not find a great variety. Almost all the radio alarm clocks currently on the market use led technology, which is particularly advantageous given the low costs, the good energy efficiency, and the high level of brightness that can be reached.

Touch Sensitivity

It must be said that radio alarm clocks do not normally have a real touch screen, comparable, for example, to that of a smartphone. However, some models are equipped with a display capable of detecting the touch, which makes it very quick to activate it if you want to check the time in the middle of the night or if it is turned off to save energy.

Mirror

Some displays have a reflective surface that can be used as a mirror. This is not an addition that brings particular benefits and represents more than anything else a design choice. ‘

During the day, moreover, the time display can be more difficult given the possible lack of good contrast between the background of the display and the digital numbers.

Curved Design

Also, in this case, it is a purely aesthetic element. The display is slightly curved and can offer a greater number of combinations for the realization of innovative, compact, and less banal designs compared to the old clock radios, often very bulky.

Choice of Watch Design

Some more advanced displays can also be customized according to user preferences. Usually, the clock radios able to offer this addition allow you to choose between more classic and another digital, more modern analog designs.

However, giving several fairly limited possibilities, which may, however, be appreciated by some users looking for a more versatile model. Design clock radio

Sound

The second element to consider before purchasing a clock radio is the sound quality and the ability to adjust it to your liking. The vast majority of the models available on the market have a small speaker, usually placed on the back of the body, which, however, is more than enough for a morning alarm clock.

However, given the increasing spread of smart speakers, which can also include a function identical to that performed by the clock radio, some brands have started to make their products more complete and complex.

It is possible to find some models that have a real case, able to offer much higher sound quality than the cheaper radio alarm clocks. Compared to smart devices, some users may appreciate in these models the advantage of not having a microphone always near and potentially active even when it has not been explicitly requested.

Another aspect of being evaluated is, as anticipated, the possibility of adjusting the volume. As a rule, it is always possible to raise or lower it according to your preferences. Still, there are also radio alarm clocks that offer the possibility to choose the ” incremental volume ” option.”.

Especially for the morning alarm. The moment it is activated, the radio is turned on at a very low volume, which is growing a little at a time, making waking up less sudden and sweeter.

This function is particularly useful for those who use the radio even during the day, perhaps increasing its volume and forgetting to turn it down again for the next morning’s alarm clock. Speaker clock radio

Additional Functions

By now, the clock radios are often equipped with many extra functions that make them much more complete and versatile devices than in the past.

In this paragraph, we will try to analyze the main ones, starting from the simplest and most common ones up to those that have been spreading only in recent years, but which represent an increasingly interesting addition for new users. Clock radio functions

Multiple Alarms

One of the most sought-after functions allows you to set two different alarms. It is useful both for those who share the alarm with other family members and are looking for a device capable of enforcing different times and for those who are afraid of completely deactivating the first alarm without getting up and prefer to take an extra safety measure.

Snooze

this function can be found in practically any model, even in analog ones without a radio tuner. It simply allows you to turn off the alarm for only a few minutes, making it ring again at regular intervals until it is turned off completely.

Very useful for all users who never manage to get up at the first alarm and need to repeat it several times.

Time Projection

Even this small addition has been widespread for several years now. It is a very compact projector, usually positioned next to the display and tiltable according to individual needs, which allows you to view the time on the wall of your room.

The projection, usually, does not always remain active, but is activated by a special button and lasts only a few seconds. It is an effective alternative to the display backlight, which can be much more annoying in the middle of the night in a completely dark environment.

Temperature and Humidity

Some clock radios are equipped with some additional sensors that allow to detect the temperature and, sometimes, the humidity rate of the room in which they are located.

The level of precision normally offered by devices designed specifically for this purpose cannot be expected. However, it can still be useful to have an idea of ​​the conditions of the environment in which one rests.

Charging Mobile Devices

The presence of one or more USB ports that allow the connection and charging of a smartphone or tablet have now become extremely widespread, even among the budget radio alarm clocks.

It should be considered that recharging will still be slower if compared to that carried out via the power supply connected directly to the power outlet. Still, it can be a valid alternative if it is used overnight.

Bluetooth Connectivity

some clock radio models, especially those that have a large speaker, are also equipped with Bluetooth. This allows you to use them as real Bluetooth speakers by connecting a mobile device to listen to your favorite tracks.

Aux Port

As for the connection via Bluetooth, it is integrated almost exclusively in radio alarm clocks equipped with a good quality speaker and allows connection via jack cable with external devices.

Direct Playback

Sometimes there is also a USB port that can read external storage media such as hard drives or USB sticks, directly reproducing the music files. In this case, it is necessary to check in advance which formats are supported, even if MP3 files normally ensure excellent compatibility.

Supply

One of the biggest shortcomings of the old clock radios was their dependence on the electricity grid. The problem was not so much in having to keep them constantly connected to the power supply but in the loss of the exact time and alarms set if there was even a very brief power outage.

For this reason, it was often necessary to set another alarm to be sure not to get up too late, especially on important occasions. Today, however, several options allow you to combine power supply on one side, alkaline batteries, or lithium batteries on the other, which only come into operation when the power is interrupted.

It is advisable to look for a radio alarm clock that offers the possibility of using rechargeable alkaline batteries, or a lithium battery, both to avoid continuous expenditure and to reduce the dispersion of polluting material into the environment as much as possible.

How to Use Clock Radio

How Does a Clock Radio Work

A radio alarm clock is an electronic device that, in addition to showing the time and allowing you to set the alarm at a preset time, also allows you to tune in to the radio frequencies of the radio stations present in your reference areas.

It is often conceived of a small size to allow its transport and when equipped with a battery, also for outdoor use.

How Do I Set the Time

Each digital clock radio is built with different mechanisms that allow you to set the time and on which the same calculation accuracy of the device also depends.

The most precise calculators to calculate the passage of time are those that use the resonance frequency of an atom as a reference base; then, some are programmed to tune in via radio waves and the simplest ones on the market that can be set manually.

Can the Volume Be Set

When choosing a clock radio, you should always be careful with this small information, as it could make a difference in the quality of use of a product. Not all radio alarm clocks allow you to change the alarm volume at will.

Is There Always a Need to Use Electricity

In the latest generation digital radio alarm clock models, a compartment is often created to use one or more batteries that allow it to be transported and used outdoors, but care must be taken.

However, since, on the other hand, there are models which being conceived as indoor devices, although they have a battery, they still need electricity to function.
