MPEG-1 or MPEG-2 Audio Layer III,[4] more commonly referred to as MP3, is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.

Any type of computer with sound output can play an mp3 file. Bluetooth is merely a type of sound transfer from the player to the speaker or headphone.
If you want to use a computer, you are just going to have to use a computer. Google.com is the main search engine for everything. You can search for "google advanced" to get instructions on how to narrow search results, but in most cases you will get a link to what you want in the first or second page. Go to google.com and type "mp3 player loudspeaker" for a start.
How do you find a MP3 player that plays out loud, and that ear pieces are not needed to play the sound. Thanks!
