Abstract
The invention discloses a portable table with an amplifying circuit. The portable table comprises a table top and table legs, wherein four magnetic seats are arranged on the table top and attract the table legs onto the table top through magnetic force. The table top is made of a hose, and the rigidness of the hose can be adjusted by adjusting the magnetic force on the hose through the magnetic seats. A pressure sensor is arranged on the table top and transmits signals converted by an analog to digital (A/D) converter to a singlechip which adjusts the magnetic force on the hose through the magnetic seats according to the signals transmitted by the pressure sensor. The amplifying circuit is electrically connected between the pressure sensor and the singlechip. The table legs are fixed on the table top through the magnetic force, so that the installation is convenient. The magnetic force is adjusted through the bearing pressure of the table top, so that the table legs can bear large pressure, and the purpose of convenient installation and large bearing weight can be achieved. Therefore, the portable table with the amplifying circuit has the advantages of being convenient to install and large in bearing weight.
