ABSTRACT:
A generator for charging the battery of a portable instrument such as a portable telephone, a player or the like, includes a permanent magnet in the form of a bar mounted freely in rotation about a pivotal axle corresponding to its median axis, within a magnetic circuit which is the core of a winding, the permanent magnet carrying a weight adjacent one of its ends, this assembly being mounted in the instrument such that, during movement of the portable instrument, the magnet unbalanced by the weight, pivots about its axle and relative to the magnetic circuit, which induces, in the winding, a current used to charge the battery of the instrument.
