The invention relates to a vibration detection structure comprising a light source assembly and a receiving sensing assembly arranged above the light source assembly; the light source assembly comprises a first grating electrode, a second grating electrode is arranged above the first grating electrode, and a light-emitting block is arranged between the first grating electrode and the second grating electrode; the vibration detection structure is not only high in sensitivity but also is not easily interfered with by an electromagnetic field, the structure is simple, the vibration detection structure can be made into a sensor or a vibration detection device with smaller size and can be applied to application fields of complex electromagnetic environment and narrow space, on the other hand, the vibration characteristic can be adjusted by changing the temperature of a heating plate, so that the vibration frequency to be monitored is changed, the optical characteristic is stable, and the self-recovery function is
