Without getting technical, it's the same way as they did on the old Commodore 64, and the IBM XT & AT, (if you recall these computers did not have "sound blaster" type audio abilities), It's a very old technique. You basically have a tone that is generated and this tone is then modulated by the audio data content. In the C64's case it was 1 or 2 KHZ (very very low quality) (a rapid pulses of beeps). I suspect the audio generation in Teal Movie is similar. A Visor is comparable to a MacSE or MAC II, so it has a bit more power but lacks the audio hardware the basic Mac's have and is in the same boat at the C64 or original IBM XT or AT.
