Super Antenna for smartphones in 5 minutes! Master OK

You just do not laugh once, it is better then if you want. This hit the result of today's boredom. It has long been thought how to do without the antenna for the radio, if there are no headphones at hand. Headphones on my work in the way, and without them, the speaker it does not work. Builders and young people will understand me for sure.

Reference. Radio through the speaker in most smart phones only works with headphones.

I was not sure what will work, but decided to try out the "difficult" option - plug in connector (usually "Jack") 3.5 mm trimming wiring. If it is interesting that came out of it, look at a short video of the experiment, it is lower. But here in order tezisno

Going principle, the details can be modified

In the interior of the cabinet with the tool dug up a piece of two-wire 2h1.5 mm (cross-sectional area of ​​1.5 square meters. mm). Cut from it of 10 cm. I approached it, but I recommend and others to try. If a solid wire, cut off from him two pieces of equal length as I do not mind.

We clean the insulation on one somewhere 1.5 cm, and then the second, only a little more at least 3 centimeters. At one bends the wire in half, but the photo he is blue. And the second is left as is, only a little roll up veins.

Overriding step - manufacturing antenna.

To get trained aerial two wires are twisted as in the photo below. Note that stranded helix on top of the blue wires bare wires do not touch the veins of the second wire. Check this point. Better to stranded wire ended at 0.5 cm from the end insulation. So not exactly closes.

It remains to insert, twist the antenna into the connector and check. Insert more comfortable turning in a spiral, so that the stranded wire is not crawled. If the thickness of the wire is chosen correctly, will normally twist. Now we check the performance of nanotechnology in practice, including the receiver.

As seen in the picture radio play, it remains only to switch it from the headphone mode to speaker mode. Well, screaming at all! At this point, the video was shot in a lively and there is clearly seen as insert twist. Sometimes you need to put it a little deeper, but just work.

This ingenuous idea will appeal not only to young people but to everyone who encountered a problem in incorporating radio FM-receiver, a conventional mobile phone or somewhere else.

Try it, beyond its budget probably will not work, but the pleasure of trifling affairs exactly get, and that's OK!
