The magnet set is installed in the installation chamber via adsorption, the magnet set includes a circular magnet 3 which adopts a neodymium-iron-boron material and a cylindrical magnet 4 which is installed in the circular magnet 3 and which adopts a neodymium-iron-boron material, and magnetic poles at a lower end of the circular magnet 3 and of the cylindrical magnet 4 have opposite polarities. An inner surface of the circular magnet 3 is continuously provided with grooves and bulges which serve as first strengthening structures configured to reinforce connection strength between the circular magnet 3 and the cylindrical magnet 4. An outer surface of the cylindrical magnet 4 is continuously provided with grooves and bulges which serve as second strengthening structures configured to reinforce connection strength between the circular magnet 3 and the cylindrical magnet 4. A gap is formed between the circular magnet 3 and the cylindrical magnet 4, and the gap is filled with gel, in this way, the gel enters grooves of the outer surface of the cylindrical magnet 4 and grooves of the inner surface of the circular magnet 3, respectively, thereby strengthening connection strength between the circular magnet 3 and the cylindrical magnet 4. The lower end of the cylindrical magnet 4 is provided, in a matching manner, with a rounded magnetic conductive sheet 6 which adopts a process of double-sided grinding, the lower end of the circular magnet 3 is provided, in a matching manner, with a circular magnetic conductive sheet 5 which adopts a process of double-sided grinding, and the rounded magnetic conductive sheet 6 and the circular magnetic conductive sheet 5 form a magnet protection structure which protects the magnet from being damaged.

The magnetic installation base has a stronger adsorption capacity, and tests prove that the adsorption capacity can reach 580 N. When under vibration, the to-be-tested object will vibrate along with the acceleration sensor, and a piezoelectric element inside the acceleration sensor will generate electric signals and then output the electric signals.
