  • Publication number: 20060185498
    Abstract: The present invention relates to a method for manufacturing a keyboard using silicon rubber and a keyboard so manufactured. The method for manufacturing the keyboard according to the present comprises the steps of forming sheets from silicon rubber, forming the sheets into a top pad with keys integrally formed thereon and a bottom pad bonded to a bottom surface of the top pad, painting the keys through a silk-screen printing method, and boding the top and bottom pads with silicon liquid rubber in a state where a flexible printed circuit board is interposed between the pads. The keyboard of the present invention is configured in such a manner that a plurality of the painted keys are arranged on a top surface of the top pad and the flexible printed circuit board is interposed between the top and bottom pads so that the flexible printed circuit board is electrically contacted to produce a desired sound from a speaker of a controller when a user strikes the keys.
