Abstract
An electromagnetic energy transducer configured to convert mechanical energy into electrical energy comprises two magnetic elements including a permanent magnetic element and a soft-magnetic element and an electrical coil. The permanent magnetic element and the soft-magnetic element are arranged to form a magnetic circuit and one of the two magnetic elements is movable in relation to the other of the two magnetic elements. The electrical coil surrounds a part of the soft magnetic element. The movable magnetic element is held in a first position by a spring force and moved into a second position by applying an external mechanical force exceeding the spring force, and at the first position the magnetic flux within the soft magnetic element is different than the flux at the second position.
