Abstract
The invention discloses a keyboard, including at least one key, wherein the key comprises a keycap, a base, a side wall, an airbag, and a key switch; the side wall is in a sealing state, extends upwards from the base surface and is connected with the keycap; the airbag is arranged on the base; the key switch is sealed in the airbag and used for generating a key signal when in enclosure; and a sealing cavity body filled with liquid is formed among the keycap, the base, the airbag and the side wall in a sealing state. By using the key, as the keycap, the side wall and the base are designed into a whole, the force conduction is realized by the internal liquid pressure, therefore the noise generated by mechanical contact when the key is knocked can be removed; by being sealed in the airbag, the key switch is led to be completely isolated with the outside world, and truly waterproof function can be achieved.
Description
Technical field
The present invention relates to the input technology of electronics or communication products, be specifically related to a kind of keyboard.
Background technology
At present, waterproff keyboard and noiseless keyboard commonly used mostly are the film tactile keyboard, and the film tactile keyboard is a kind of of Mechanical Contact formula keyboard, and its key switch is a conductive contact, rely on conductive contact to be communicated with and produce push button signalling.
Waterproff keyboard has been set up the water guide channel on the basis of general thin tactile keyboard, make the low amounts of water that enters keyboard can dredge and flow out keyboard, can not contact with key switch; Another part waterproff keyboard makes key switch be isolated from the outside by good seal isolation mechanism.
But the inventor finds that the former only can derive keyboard with low amounts of water, when toppling over big water gaging to keyboard or when immersing keyboard in the water, just inevitably key switch is contacted with water, causes the keyboard circuit short circuit; The latter uses the mechanical structure seal isolation, and sealing technology is had relatively high expectations, and makes the cost of water-tight equipment also higher, and mechanical seal still can not make the long-time immersion of keyboard and the phenomenon that is not short-circuited.
And noiseless keyboard adopts elastomeric material to make button, pedestal, and adopt metallic silicon to make contact point, reduce the noise that key tap produces, but when knocking keyboard, the Mechanical Contact of the elasticity keycap of the keycap of button and the pedestal of keyboard, button and pedestal etc., still can produce noise, make keyboard only the noise that key tap produces can be decreased to 20～30dB.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of keyboard, has reached the purpose of the noise of waterproof and the generation of elimination key tap.
For achieving the above object, technical scheme of the present invention is achieved in that
