A touch pad, comprises a housing comprising a vibration device, a cover, a capacitive sensing layer electrically connected to a processor and a pressure sensing layer arranged in the housing, also electrically connected to the processor. The capacitive sensing layer is positioned between the cover and the pressure sensing layer. The processor is configured to utilize a signal output from either the capacitive sensing layer or the pressure sensing layer to activate the vibration device.

Touch pad

An electronic keyboard comprises a plurality of keys and a housing comprising a cavity. The cavity accommodates a circuit board, a pressing layer and at least one pressure sensor arranged therein. Each pressure sensor is provided between a lower portion of the cavity and the circuit board, the pressing layer is moveably connected to each of the keys and the circuit board is provided between the pressing layer and the lower portion. Each pressure sensor is connected to the circuit board, and a force-receiving surface of each pressure sensor aligns with a projection area of the corresponding one of the keys.

Electronic keyboard

A button structure has a base having a slot and a sensing element inserted into the slot. A pressure concentration element is fixedly connected by bonding to the sensing element and a key cap is mounted to the base. The key cap has a core member fixedly connected to a lower surface of a top plate of the key cap. The lower surface of the core member can be brought into contact with the pressure concentration element on application of a pressure to an upper surface of the top plate, such that the applied pressure is transmitted to the sensing element through the core member and the pressure concentration part. The sensing element is a piezoresistive film sensor.
