    摘要： An electromechanical energy converter (1) is provided that can convert mechanical vibration energy into electrical energy. For this purpose, the energy converter (1) has a housing (2) in which a coil (12) and a permanent magnet (15) are disposed moveable with respect to each other, the coil (12) lying within the magnetic field of the magnet (15). To fully utilize the entire field intensity of the magnet (15), flux guides (18) are disposed at the poles of the magnet (15) that divert the magnetic flux lines (17) substantially in the direction of the coil (12).
