键盘双模是可以使用无线连接功能,也可以通过无线蓝牙技术连接到电脑中,相比于有线键盘,无线键盘要方便很多,在有效连接范围内都可以使用,不需要担心连接问题。
键盘的分类:
1、机械式:顾名思义,组成机械式键盘的按键,为独立的微动开关,每个开关各控制不同的讯号;而依照微动开关不同,又可区分为单段式与两段式2种。机械式键盘是最早被采用的结构,一般类似金属接触式开关的原理使触点导通或断开。
2、薄膜式:薄膜式键盘内部是一片双层胶膜,胶膜中间夹有一条条的银粉线,胶膜与按键对应的位置会有一碳心接点,按下按键后,碳心接触特定的几条银粉线,即会产生不同的讯号;就如机械式键盘的按键一样,每个按键都可送出不同的讯号。
3、电容式:电容式键盘是基于电容式开关的键盘,原理是通过按键改变电极间的距离产生电容量的变化,暂时形成震荡脉冲允许通过的条件。
双模键盘就是可以使用无线连接功能,也可以通过无线蓝牙技术连接到电脑中;相比于有线键盘,无线键盘要方便很多,在有效连接范围内都可以使用,不需要担心连接问题。

The dual-mode keyboard can use the wireless connection function or connect to the computer through wireless Bluetooth technology. Compared with the wired keyboard, the wireless keyboard is much more convenient and can be used within the effective connection range, so there is no need to worry about connection problems.
Classification of keyboards:
1. Mechanical type: As the name suggests, the keys that make up the mechanical keyboard are independent micro switches, each of which controls a different signal; and according to the different micro switches, it can be divided into two types: single-stage type and two-stage type. . The mechanical keyboard is the first structure to be adopted, and it is generally similar to the principle of a metal contact switch to make the contacts turn on or off.
2. Membrane type: The inside of the membrane keyboard is a double-layered film with silver powder lines sandwiched in the middle of the film. There will be a carbon core contact at the position corresponding to the film and the button. After pressing the button, the carbon core contacts a specific A few silver powder lines will generate different signals; just like the keys of a mechanical keyboard, each key can send a different signal.
3. Capacitive: Capacitive keyboard is a keyboard based on capacitive switches. The principle is to change the distance between electrodes by pressing the button to change the capacitance, temporarily forming the conditions for the oscillation pulse to pass.
