| description | The invention relates to a strain generating device which is characterized by comprising a protection box which is a shell with an opening in the top; a mounting hole is formed in the wall of the protection box; the magnetic circuit module extends into the opening in the top of the protection box and is suspended in the protection box in a suspended state; the magnetic circuit module is fixedly connected with the free end of the cantilever beam; the driving coil is wound on the surface of the magnetic circuit module; the aviation socket is embedded in the mounting hole, the aviation socket is electrically connected with the driving coil through a wire, and Ampere force is generated between the driving coil and the magnetic circuit module in a power-on state so as to drive the free end of the cantilever beam to swing. The strain generating device can provide steady-state sine excitation for the free end of the cantilever beam, so that the fixed end can generate strain with specified magnitude, the vibration fr |
