"Megaphone" MP3 player

3D model description

Simple MP3 decoder board connected to horn speaker.
The goal was to demonstrate horn audio amplification using different horn shapes.
Don't expect superior audio quality but it's ok for making bathroom activities more comfortable :-)

MP3 decoder can play music from a microSD card or from a flash disk.
