I made this speaker for my girlfriend’s birthday. It’s basically a combination of a tin can enclosure, a 3D-printed cover and the necessary electronics. Intead of a built-in battery I included an internal mount that can hold small powerbanks with the help of two plait gums.

In retrospect the tincan is probably not an ideal enclosure as it seems to act as a big antenna that picks up noise and feeds it into the audio signal. Apart from that, did you ever hear someone say “that speaker sounds like a tin can”? Well it’s in fact true that it does not produce perfect sound
