Abstract
A keyboard including a substrate and a key structure is provided. The key structure is disposed on the substrate and includes a keycap, an antenna, and a sensor. The keycap is disposed on the substrate, and a length of the keycap is greater than a width of the keycap. The antenna is disposed on a back surface of the keycap facing toward the substrate. The sensor is disposed below the keycap and is electrically connected with the antenna.
Claims18
A keyboard, comprising:
- a substrate;
- and
- a key structure, disposed on the substrate and comprising:
- a keycap, disposed on the substrate;
- an antenna, disposed on a back surface of the keycap facing toward the substrate;
- a sensor, disposed below the keycap and electrically connected with the antenna, wherein the antenna is closer to a top surface of the keycap than the sensor is, and the top surface faces away from the substrate and is opposite to the back surface, wherein the sensor comprises a proximity sensor, and the antenna serves as a sensing antenna of the proximity sensor that is being conducted;
- and
- an electronic assembly, disposed below the keycap and electrically connected with the sensor, wherein the sensor converts an operation mode of the electronic assembly in response to a change sensed by the antenna.
