Patent ID: 7482543

Claim:
A signal generating module, adapted for an electronic apparatus having a housing and a circuit board disposed in the housing, the signal generating module comprising: a processor, disposed on the circuit board; an arcuate elastomer, disposed in the electronic apparatus, and comprising a first movable contact and a second movable contact, wherein a portion of the arcuate elastomer is exposed out from the housing; a first fixed contact, fixed to the electronic apparatus, corresponding to the first movable contact; a second fixed contact, fixed to the electronic apparatus, corresponding to the second movable contact; a first pin, secured to the circuit board, coupled to the processor, and coupled to one of the first fixed contact and the first movable contact; and a second pin, secured to the circuit board, coupled to the processor, and coupled to one of the second fixed contact and the second movable contact, wherein when no external force is applied on the arcuate elastomer, the first movable contact stays isolated from the first fixed contact, and the second movable contact stays isolated from the second fixed contact either; and when an external force is applied on the arcuate elastomer and the elastomer is deformed, the first movable contact comes in contact with the first fixed contact, and/or the second movable contact comes in contact with the second fixed contact so that the processor generates a control signal by evaluating signals transmitted from the first pin and the second pin.
