Abstract

An input device includes a device body, a cable, and a piezoelectric structure. The cable is connected to the device body. The piezoelectric structure is disposed within the cable. When the piezoelectric structure is energized, it deforms, causing the cable to bend. Furthermore, the input device may include a plurality of electromagnetic structures spaced apart within the cable. When at least two adjacent electromagnetic structures are energized, they magnetically attract each other, shortening the cable length. With this design, the input device allows users to freely control the cable bending and / or change the cable length according to their operating habits, thereby effectively improving operational comfort.

Claims

1. An input device, comprising: a device body; a cable connected to the device body; and a piezoelectric structure disposed in the cable; wherein, When the piezoelectric structure is energized, it deforms, causing the cable to bend.

2. The input device as claimed in claim 1, wherein the piezoelectric structure includes a piezoelectric layer, a passive layer, a first electrode and a second electrode, the piezoelectric layer and the passive layer being bonded to each other, the first electrode being located on one side of the piezoelectric layer and the second electrode being located on one side of the passive layer.

3. The input device as claimed in claim 1, wherein the bending angle of the cable varies with the voltage applied to the piezoelectric structure.

4. The input device as claimed in claim 1, wherein after the piezoelectric structure is de-energized, the piezoelectric structure recovers, allowing the cable to bend freely.

5. An input device, comprising: a device body; a cable connected to the device body; and a plurality of electromagnetic structures spaced apart from each other in the cable; wherein, When at least two adjacent electromagnetic structures among the plurality of electromagnetic structures are energized, the at least two adjacent electromagnetic structures attract each other magnetically, thereby shortening the length of the cable.

6. The input device as claimed in claim 5, wherein each of the electromagnetic structures includes a coil and a magnetic core, the coil being wound around the magnetic core.

7. The input device as claimed in claim 5, wherein the cable comprises a plurality of wires, an insulating layer and a sheathing layer, the plurality of electromagnetic structures are disposed on the plurality of wires, the insulating layer covers the plurality of electromagnetic structures and the plurality of wires, and the sheathing layer covers the insulating layer.

8. The input device as claimed in claim 5, wherein the plurality of electromagnetic structures are divided into a plurality of electromagnetic groups, the plurality of electromagnetic groups corresponding to a plurality of segments of the cable; when the i-th electromagnetic group in the plurality of electromagnetic groups is energized, the length of the i-th segment in the plurality of segments corresponding to the i-th electromagnetic group is shortened, where i is a positive integer.
