Abstract
A power generator for a Digital Cassette Cartridge, which is put into a cassette player for playing back the digital audio files stored in the Digital Cassette Cartridge. The cassette player contains a reel shaft for driving the power generator of the Digital Cassette Cartridge. The power generator includes two gears, a magnetic object, a coil and a power supply. The first gear is coaxially engaged with the reel shafts. The second gear rotates as the first gear rotates. The magnetic object is coaxially mounted and is conjointly rotatable with the second gear. The coil produces an alternating current source when the magnetic object rotates. The power supply receives the alternating current and converts the alternating current to a direct current source.
