Wireless keyboard Dell inspiron 9300 Keyboard

Wireless keyboard Dell inspiron 9300 Keyboard Dell inspiron 6400 keyboard Dell inspiron E1505 keyboard that works primarily through a wireless receiver connected to the host computer system. Keyboard and mouse usually can share a wireless receiver, but the two different channels of radio waves and, therefore, there will be no interference or can not receive / send love the offense. It is due to the wireless keyboard uses radio waves as a transmission tool, so to receive and send the results are quite good, is not vulnerable to the impact of surrounding Zhang Bi objects, even if the keyboard is not working right or the receiver is completely the opposite direction, as long as the reflex zones in the operating environment can exist in normal operation, even in the receiver pre-installed plus a set of obstructions, too, can work properly. Moreover, in addition to the use of radio waves for data transmission, are also part of the market to carry out transmission using infrared wireless keyboard. However, this wireless keyboard because of changes in transmission patterns, and its work is not only shorter distances to work effectively, but also the work of the infrared receiver, which also must be in a barrier-free status, because if the receiver before any obstacles, then the wireless keyboard are susceptible to interference caused by the work of receiving and sending of the effects of greatly reduced. IR emitter are generally need to use battery-powered, but because infrared transmitter power is very small, two pairs of ordinary batteries will be able to spend more than three months on the 7th, most of the wireless keyboard has a small red lights, When the red light when it was to remind the user needs to replace the battery of the current market among the large number of keyboard brand to launch a lot of waterproof keyboard. There are a lot of people know that there waterproof keyboard, but for How waterproof keyboard is not very clear. Today, I Jiuji you briefly tell us about some of the principles of water-proof keyboard.

Currently on the market a lot of brands have launched their own water-resistant keyboard, such as Microsoft, Logitech, BenQ, Patriot, etc.. How did this kind of will to prevent the liquid into the circuit board
game?





Above, these two images allows users to clearly understand the basic principles of keyboard waterproof design, although some water-proof keyboard, this is not the principle, we will talk about below. Waterproof keyboard on the market today rely mainly on water diversion trough structure, waterproof structure to achieve results. Under normal circumstances, waterproof keyboard will be used relatively low-cost high-pin key-bit design, interior design of a dedicated keyboard, flume, in which case the liquid outflow of in vitro relatively easy. And the keyboard is also back out the drainage holes, you can smoothly guide the fluid flow out, so as to achieve the purpose of waterproof keyboard. However, if a large number of liquid splashing into the case, believe that your keyboard is still difficult to preserve Oh Baby.
