Seismic generator, has bearing spring connected with magnet and loading magnet with spring force during movement of magnet in direction of coil arrangement, where spring force acts opposite to movement direction of magnet

摘要

The generator has a permanent magnet (23) arranged in a retaining housing (1) in a movable manner, and a flat coil (14) penetrated by magnetic field of the magnet. The flat coil extends in a coil plane, where the magnet is supported in a movable manner at a right angle to the coil plane. A bearing spring (17) designed as a flat plate is connected with the magnet, and loads the magnet with spring force during movement of the magnet in the direction of the flat coil, where the spring force acts opposite to movement direction of the magnet.
