Abstract
A keyboard device includes a base plate, plural keys and a membrane circuit board. The keys are connected with the base plate. The membrane circuit board is arranged between the keys and the base plate. At least one film layer of the membrane circuit board includes at least one elastic vibration absorber corresponding to a keycap, a stabilizer bar or a reinforcement element of the corresponding key. While the keycap is moved downwardly relative to the base plate, the sound resulted from the collision between the keycap, the stabilizer bar or the reinforcement element and the membrane circuit board. Consequently, the operating comfort to the user is enhanced.
Claims15
A keyboard device, comprising:
- plural keys, wherein each of the plural keys comprises a keycap, and at least one specified key of the plural keys comprises a stabilizer bar and a reinforcement element, wherein the stabilizer bar is pivotally coupled to the corresponding keycap, and the reinforcement element is disposed on a bottom surface of the corresponding keycap;
- a base plate, wherein the plural keys and the stabilizer bar of the at least one specified key are connected with the base plate;
- and
- a membrane circuit board arranged between the plural keys and the base plate, and comprising plural membrane switches corresponding to the plural keys and comprising at least one elastic vibration absorber corresponding to the keycap, the stabilizer bar or the reinforcement element of the at least one specified key, wherein while the at least one elastic vibration absorber is collided by the keycap, the stabilizer bar or the reinforcement element of the at least one specified key, the at least one elastic vibration absorber absorbs kinetic energy of the keycap, the stabilizer bar or the reinforcement element of the at least one specified key.
