The invention relates to the field of passive power generation devices, in particular to a toggle-type magnetic power generation device, which comprising a coil, a magnetic core, a coil bobbin and a coil support. A through groove allowing the magnetic core to penetrate through is formed in the coil bobbin. The coil is wound around the outer surface of a side wall of the through groove and corresponds to the magnetic core. An opening allowing part of the coil bobbin to be embedded therein is formed in the coil support. The opening is formed in the coil support and allows part of the coil bobbin to be embedded therein, so that the number of turns of the coil is increased under the precondition of maintaining the existing size, thus improving the power generation capacity and the stability of the electrical performance of the magnetic power generation device.
