The music you will be listening to with such a speaker when you are at the seaside, lake or in a forest on vacation may play louder than your mobile phones speaker can produce.
The idea is a little crazy and interesting but as for me it is cool because I’ve never seen such an unusual portable speaker made from a lighter. It is quite pity that the battery failed us..
In general, nowadays you can easily purchase portable speakers for a cell-phone as the price is low and the supply is big. However, it’s far more interesting to make it by yourself.
Never mind soon we will order the same one from China the one we will order may even be more efficient and we will be able to enjoy listening to music with full volume on.
