键盘2.4g是键盘2.4G无线连接模式的意思。由于其频段处于2.400GHz-2.4835GHz之间,所以简称2.4G无线技术,是市面上三大主要无线技术之一,较普遍被应用于无线键盘鼠标。
键盘的种类:
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,具有工艺简单、维修方便、手感一般、噪声大、易磨损的特性。
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。这种开关是无触点非接触式的,磨损率极小甚至可以忽略不计。
答:键盘2.4G无线连接模式。键盘2.4g是键盘2.4G无线连接模式的意思。由于其频段处于2.400GHz-2.4835GHz之间,所以简称2.4G无线技术,是市面上三大主要无线技术之一,较普遍被应用于无线键盘鼠标。
【英文介绍/For English】:
Demonstration model: Huawei MateBook X
System version: win10
Keyboard 2.4g means keyboard 2.4G wireless connection mode. Because its frequency band is between 2.400GHz-2.4835GHz, it is referred to as 2.4G wireless technology, which is one of the three major wireless technologies on the market, and is more commonly used in wireless keyboards and mice.
Types 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 earliest structure adopted. Generally, it is similar to the principle of a metal contact switch to make the contacts turn on or off. It has the characteristics of simple process, convenient maintenance, general hand feeling, high noise and easy wear and tear.
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. This switch is non-contact and non-contact, and the wear rate is minimal or even negligible.
