Board card test method, terminal, test tool and system thereof

The invention discloses a board card testing method, a terminal, a testing tool and a system thereof, and relates to the technical field of loudspeaker testing, the testing tool establishes connection with the terminal through a board card, and the testing tool comprises a pressure head module and a pressure detection module, the pressure head module is provided with a first position capable of moving to be in contact with the pressure detection module and a second position capable of moving to be separated from the pressure detection module; the method comprises the following steps: when a test instruction is received, controlling a pressure head module to move to a first position; controlling the pressure detection module to output a generated pressure value to the terminal, so that when the terminal determines that the received pressure value is not less than a minimum value of a preset pressure range, the terminal outputs a stop instruction representing that the pressure head module stops moving to the te
