Horn Loaded Cell Phone Amplifier

The wood shop in my rather large retirement community makes and sells a TON of these every year, especially around Xmas. Looking it over with a new eye since thanks to BFM I now have a gnat's knowledge of what "Horn-loading" means and BINGO! It's nothing more than a horn. This constantly amazes people - we have them play music on their phone then drop it down into the rectangular slot and BAM - 5X volume increase.
