Abstract
A keyboard device includes a light guide plate, a base plate, plural keys and plural surround-type soundproof elements. The base plate is located over the light guide plate. The plural keys are connected with the base plate. The membrane circuit board is arranged between the plural keys and the base plate. The plural surround-type soundproof elements are aligned with the corresponding keys. Each surround-type soundproof element is disposed on the light guide plate, the base plate or the membrane circuit board. While one of the plural keycaps is depressed and moved downwardly relative to the base plate, a sealed space is defined by the corresponding keycap and the corresponding surround-type soundproof element.
Claims20
A keyboard device, comprising:
- plural keys, each of the plural keys comprising a keycap;
- a base plate, wherein each of the plural keys is connected with the base plate;
- a membrane circuit board arranged between the plural keycaps and the base plate, and comprising plural membrane switches corresponding to each of the plural keys;
- and
- plural surround-type soundproof elements, each of the plural surround-type soundproof elements being aligned with a corresponding one of the plural keys, and disposed on the base plate or the membrane circuit board, wherein while one of the plural keycaps is depressed and moved downwardly relative to the base plate, a sealed space is defined by the depressed keycap and a corresponding surround-type soundproof element.
A keyboard device, comprising:
- plural keys, each of the plural keys comprising a keycap;
- a base plate, wherein each of the plural keys is connected with the base plate;
- a membrane circuit board arranged between the plural keycaps and the base plate, and comprising plural membrane switches corresponding to each of the plural keys;
- a light guide plate located under the base plate, wherein when a light beam is received by the light guide plate, the light beam is guided upwardly to the plural keys by the light guide plate;
- and
- plural surround-type soundproof elements, each of the plural surround-type soundproof elements being aligned with a corresponding one of the plural keys, disposed on the light guide plate and penetrated upwardly through the base plate and the membrane circuit board, wherein while one of the plural keycaps is depressed and moved downwardly relative to the base plate, a sealed space is defined by the depressed keycap and a corresponding surround-type soundproof element.
