description A diaphragm sensor for a touch pen comprises an elastic deformation element, a strain gauge, a force transmission part, an outer cylinder and a center retaining part. The strain gauge is arranged on the elastic deformation element, the geometric center of the lower surface of the elastic deformation element is vertically provided with a force transmission piece, and the force transmission piece is fixedly sleeved with a center retaining part; the outer edge of the elastic deformation element and the outer edge of the center maintaining component are fixedly connected with the inner side wall of the outer cylinder. The pressure sensor assembly adopts a diaphragm force measuring structure, the pressure generated when the pen point of the touch pen is in contact with a writing flat plate or a panel is converted into a resistance change or tiny voltage electric signal, the corresponding electric signal is output by detecting the strain of the strain gauge pasted on the diaphragm, and the pressure of the touch pen
