Make speakers for your own phone
Who has not got a video with sound on his mobile phone at home? In the trade I have now discovered that there are wooden racks that are open at the front and how a loudspeaker works.
But first I wanted to try it myself. That's why I cut a slot in an empty and washed-out yoghurt cup (250 g) and put the phone in such a way that the phone's speaker is in the cup. The sound was amazingly louder and fuller.
So that the whole thing does not fall over, I glued a substructure together by means of a cardboard with adhesive tape. You can, you do not have to.
Anyone who wants can make the cut in the cup almost on the ground and put the phone in there at night. The alarm clock is then louder.
Ingeniously simple. Just awesome.
