Inductive keyboard device

An inductance type keyboard device comprises a circuit board, an annular inductor and keys. The circuit board is provided with an assembling area, and the assembling area is provided with holes. The annular inductor is arranged in the hole, and the annular inductor surrounds to form an axial induction channel. The key comprises a key cap and a magnetic part, the key cap is arranged above the assembly area and located at the height position, the magnetic part is connected to the key cap, and the position of the magnetic part corresponds to the position of the axial induction channel. Wherein the key cap can move from the height position to the direction of the circuit board, and in the moving process of the key cap, the key cap drives the magnetic part to axially move in the axial induction channel of the annular inductor. 一种电感式键盘装置包括电路板、环状电感及按键。电路板具有组装区，组装区具有孔洞。环状电感设置于孔洞内部，环状电感环绕形成轴向感应通道。按键包括键帽与磁性件，键帽设置于组装区上方并位于高度位置，磁性件连接于键帽，且磁性件的位置对应于轴向感应通道的位置。其中，键帽可由高度位置朝电路板的方向进行移动，且键帽于移动的过程中，键帽带动磁性件于环状电感的轴向感应通道中轴向位移。
