Here’s a rather strange but pretty design. The Green Voice concept speaker is powered by a paper battery and uses empty recycled PET bottles to function. It’s a strange design, but you can’t deny that it serves as a good form of modern decoration that can be used to keep you entertained while helping you ensure your home looks modern. The use of different bottles will help you get different designs with the speaker, which helps to differentiate it from the rest.
