Mini-Jack, nice to meet you
Welcome to the iCover blog! Do not argue with the fact that multi-functionality - one of the priorities declared in the development of models of modern mobile devices. But, despite the progress made in this direction, the good old audio jack, which is present in the vast majority of smartphones, is still most commonly traditionally used for its intended purpose - to connect a headset and listen to music and audio books. Perhaps not everyone knows that the mini-jack has other possibilities of use that may be very useful for us.
The first, easiest way to expand the possibilities of an audio jack is to double its efficiency by connecting an external splitter. This option will allow you to listen to the audio or watch a movie at once to two users, “equipped” with personalized sets of headphones.

The solution presented in the illustration is as compact as possible. However, the rigidity of the monolithic structure requires the user to be especially careful and have some dexterity in handling.
As a safer and more comfortable option, a splitter with a short connecting wire can be used.
The return to the somewhat “retired” technology of the infrared port used in many new models of smartphones for controlling home electronics was perceived ambiguously. Yes, and how to be the owners of those models in which the IR transmitter is not provided initially, but there is no possibility to change the device yet? For them, the engineers came up with compact universal IR adapters, which are inserted just into the audio jack of a smartphone on Android or iOS. And in order for such an adapter to “live” and allow using your device to comfortably control virtually any home electronics and home appliances, just download and install a special companion application for the OS used on the smartphone. The range of the useful signal of low-cost infrared adapters, on average, 9-12m.
Another option for the useful use of the audio jack is the instant access and activation of some frequently used functions or capabilities of the device - a voice recorder, a flashlight or, for example, a tablet camera that does not have a separate mechanical button to release the shutter. In such and similar cases, the smart button (smart key) inserted into the mini-jack and activating the priority function at the right time with one click will become a simple and convenient way out.
When purchasing a smart button model, note the compatibility requirements for your device. After installing and customizing the appropriate application, everything is ready for operation. Feel free to insert the button into the socket and use when necessary.
Fans of midnight and nighttime Selfie using mobile gadgets will probably need a flash. But it may not be in the device by definition, or at least on its front panel. The way out of the situation will be a miniature detachable LED flash inserted into the audio jack of the device as needed.
One of the advantages of this solution is that the flash works from its own built-in battery and does not consume the battery charge of the main device. At the same time, the low power consumption of the LED flash will allow you not only to take pictures from the bottom of your heart, but also to replenish your home video collection.
For a symbolic price today, you can pick up a stylish, compact and efficient model with the ability to adjust the brightness level, without problems and discomfort to carry it in your jacket pocket, purse or bag.
Despite the absence of any kind of “intellectual” load, the button inserted into the audio output jack of a smartphone or tablet will perfectly cope with the responsible mission of protecting the connector from dust.
The fair sex will be able to choose for themselves a miniature button with a rhinestone or jewelry, and will gladly accept this elegant accessory as an original and, if not an arch-expensive, but certainly useful and successful gift.
