Seesaw type double-coil magnetic generating device

A seesaw type double-coil magnetic generating device comprises a permanent magnet, an iron core, a coil and a soft magnetic material, wherein one end of the permanent magnet is connected to the middle of the iron core, and the other end of the permanent magnet is connected to the middle of the soft magnetic material. The coil is wound on the iron core. The coil is wound at two ends of the iron core, and the permanent magnet, the connected iron core and the soft magnetic material form a seesaw structure. The seesaw type double-coil magnetic generating device overcomes the shortcomings that numerous magnetic generating devices with a generator serving as a representative are complex in structures and large in sizes, can convert short-stroke translational mechanical energy into electric energy, is pollution-free and particularly suitable for application occasions of the micro-energy harvesting fields such as switches, keys and vibration environments, and is one of ideal energy solutions for micropower wireless sensor networks. The seesaw type double-coil magnetic generating device is wide in applied range, low in cost, small in size, free of pollution and simple in structure.
