1. A touch button having multiple control functions integrated thereon, comprising: a first conductive part; a second conductive part; and a touch part,
wherein the second conductive part partially surrounds the first conductive part, a portion of the first conductive part is exposed from the second conductive part, a gap exists between an unexposed portion of the first conductive part and the second conductive part, and the first conductive part is movable relative to the second conductive part; and
the touch part comprises a touch member and an elastic member wherein the touch member is configured to transfer pressure to the exposed portion of the first conductive part through the elastic member, wherein the elastic member wraps the exposed portion of the first conductive part and is positioned above the second conductive part,
wherein a touch input received by the touch part causes a capacitance change between the first conductive part and the second conductive part in one of a plurality of preset directions, and each preset direction corresponds to a different control instruction detectable by the touch button.
