Wireless speaker Smartphone - No Wifi, no Bluetooth , no cabels

I bought a Intempo wireless speaker for my phone. The speaker itself was not expensive, it cost 8 euros ... and for that money I will not let this kind of gadgets go. I tried it ... and to my surprise, the speaker gives a great sound. Technical specifications are unfortunately not mentioned, yet I found it worthwhile to show this speaker on Youtube (Excuse my writing, english is not my main language).
