Summary:The invention provides a keyboard device which comprises a circuit board, a first key and a second key, and the circuit board is provided with a magnetic sensing switch and a processor. The first key is arranged above the circuit board, the first key is provided with a first side, and the first side is provided with a first magnet. The second key is arranged above the circuit board, the second key and the first key are arranged side by side, the second key is provided with a second side, the second side is provided with a second magnet, and the magnetic sensing switch is located between the first side and the second side. Wherein the magnetic sensing switch outputs a first voltage according to the approaching of the first magnet, and the processor outputs a first trigger signal corresponding to the first key according to the first voltage. The magnetic sensing switch outputs a second voltage according to the approaching of the second magnet, the second voltage is different from the first voltage, and the proc
