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 :-)

You can parametrize your own horn shape and size:

MP3 decoder can play music from a microSD card or from a flash disk.
Available cheap at eBay:
"TF Card U Disk MP3 Format Decoder Board Audio Decoding Module W/ Amplifier"

Loudspeaker used:
"1.5" inch 4Ohm 4Ω 3W Full Range Audio Speaker Stereo Woofer Loudspeaker"
