POWER GENERATOR

摘要

The invention relates to an power generator comprising: a block (70) made of magnetostrictive material, and a unit (90) comprising a succession of first permanent magnets (112-115) along an alignment axis (110), one first permanent magnet being a permanent magnet which has an aspect ratio of 1/10 to 10 and in which most of the field lines that loop back by means of the block of magnetostrictive material and said first permanent magnet in a first position do not pass through another first permanent magnet. The first permanent magnets are arranged relative to one another such that the magnetic field induced inside the block (70) of magnetostrictive material by any one of said first permanent magnets is parallel and in the opposite direction of the magnetic field induced in this same block by the first permanent magnet that follows immediately afterwards along the alignment axis.
