Abstract:
In combination, a computer, and a volume control knob for controlling said computer, said volume control knob comprising:a primary control device with a resilient member, said primary control device being rotatable in a first direction, and rotatable in a second direction that is opposite to the first direction, and being pushable; and a secondary control device with at least one chip mounted thereon, and being rotatably engaged with distal ends of the resilient member, wherein when said primary control device is rotated in the first direction, said primary control device engages said chip to generate a first control signal to increase a volume of said computer; wherein when said primary control device is rotated in the second direction, said primary control device engages said chip to generate a second control signal to decrease the volume of said computer; wherein when said primary control device is pushed, said primary control device engages said chip to generate a third control signal to mute the volume of said computer; and wherein said resilient member returns said primary control device to an original position after being rotated in the first direction, after being rotated in the second direction, and after being pushed.
