Abstract
The invention discloses a portable table with an amplifying circuit. The table comprises a table top and table legs, wherein four magnetic seats are arranged on the table top and absorb the table legs on the table top through magnetic force, a hose is adopted on the table top, the rigidity of the hose can be adjusted through adjustment of magnetic force on the hose by the magnetic seats, a pressure sensor is arranged on the table top and sends signals to a single chip microcomputer (SCM) after conversion through an A/D converter, the SCM adjusts the magnetic force on the hose through the magnetic seats according to the signals of the pressure sensor, and the pressure sensor and the SCM are electrically connected with the amplifying circuit. The table has the advantages that the table legs are fixed on the table top through the magnetic force, the installation is quite convenient, the magnetic force for the table legs is adjusted according to the load-bearing pressure on the table top, so that the table legs can bear large pressure, and the bearing capacity is large.
