Abstract
An AMPG device for generation of electrical energy, including a bobbin, at least one magnet, and at least one spring member. The magnet is arranged to be movable together with the spring member. The device is arranged so that when exposed to an acceleration component in a possible path of mobility of the first magnet, the first magnet will, due to its association with the spring member, move in an oscillating manner in relation to the bobbin, so as to generate electrical energy. The device is arranged to at a limiting position of the mobile magnet's path of mobility a spring member with an equal or higher spring constant than the remainder portions of the magnet's mobile path acting on the magnet. An AMPG device assembly includes several AMPG devices. A method to optimize the electrical output of the device adapts the device to the frequencies appearing in the application where it shall be used.
