Summary: | The invention relates to vibration detection, in particular to a frequency amplification device and a portable low-frequency vibration detector, and the device comprises a swing part, a first input end of which is used for sensing mechanical vibration generated by a vibration source, and a first output end of which is used for outputting swing motion with the same frequency as the vibration source; the inductance coil is arranged at the first output end of the swing part, the inductance coil is provided with N mutually independent turns, and the first output end is located between the positive electrode and the negative electrode of the magnetic field; when the swing part swings for one cycle, the at least M turns of inductance coils can sequentially cut magnetic induction lines generated by the magnetic field source twice, and a current section is generated once every cutting; n > = M > = 2, and N and M are natural numbers; the first energy conversion device and the first energy rotating shaft device are ele |
