A system is provided for simultaneously providing mechanical motion driven by a rotatable drive shaft, and for generating electrical voltage by electrical generating means having a rotor driven at a desired speed. The system includes, as an essential element, a prime mover comprising a windable driving spring, the spring including an inter- connecting drive train for separately drivably connecting the spring to the rotatable drive shaft and to the rotor of the electrical generating means. A speed governor is pro- vided for controlling unwinding of the spring so as to cause the spring to drive the rotatable drive shaft and the rotor of the electrical generating at their restive prede- termined desired speeds. In one embodiment of this inven- tion, the system is part of an audio cassette player. Such audio cassette player includes a conventional audio play- back head located in a signal pick-up station, a rotatable drive shaft for driving an audio cassette tape progres- sively through such signal pick-up station to permit the head to receive signals from the tape, and an amplifier electrically-connected to the head to receive signals from the head. The rotatable drive shaft of the system is the rotatable drive shaft for the driving of the audio cassette tape, and the electrical power is provided for the ampli- fier means.
