Key structure for electronic product

摘要

A key structure in an electronic product includes a housing. The key structure includes a pressing portion, a printed circuit board (PCB), a key, and a sensor. The key and the sensor are both located on the PCB and electronically connected with each other. When the pressing portion is pressed, the key structure acts as a mechanical key. When the pressing portion is simply touched, the key structure acts as a touch key.

主权项

1. A key structure configured in an electronic product, the electronic product comprising a housing, the key structure comprising:
a pressing portion located at an outside surface of the housing; a printed circuit board (PCB) received in the housing; a key electrically connected to the PCB and positioned opposite to the pressing portion, the key comprising a trigger portion and a conductive cover; a conductor located between the conductive cover and the pressing portion; and a sensor electrically connected with the conductive cover; wherein when a first area of the pressing portion corresponding to the trigger portion is pressed, the key structure acts as a mechanical key; and when a second area of the pressing portion corresponding to the conductive cover is touched, the sensor receives a signal of a change of capacitance transmitted by the conductive cover, and the key structure acts as a touch key.
