What is the difference between a mechanical mouse and an ordinary mouse?
The mechanical mouse was cheap at the time, and the manufacturing cost of the optical mouse can be controlled very low now. Generally speaking, the technology is mature, and the optical mouse is better used instead of the mechanical mouse. After the increase in output, the optical mouse does not have a small ball at the bottom of the mechanical mouse.
Only the keyboard is mechanical, which is more durable than ordinary keyboards. The sound is louder than ordinary keyboards. Ordinary keyboards are cheap. If you are afraid of water, you need to deal with it correctly, otherwise it may be scrapped, but the price is more expensive.
According to the principle, the mouse can be divided into two categories: mechanical mouse and optical mouse.
The advantages and disadvantages of optical mouse and mechanical mouse:
(1) Mechanical mouse, also known as wheel mouse, is mainly composed of rolling ball, roller and grating signal sensor. The mouse is connected to the host through the ps/2 port or serial port. Four wires are generally used in the interface, which are power, ground, clock and data. The optical mouse completely got rid of the ball-roller mechanical structure of the mechanical mouse, and replaced it with a high-precision optical sensor (Optical Sensor), thus getting rid of the shackles of the mouse pad, and can be used on a variety of surfaces (except for reflective surfaces) .
(2) The optical mouse does not have the scroll wheel of a mechanical mouse, so the dirt on the desktop will not be rolled into the mouse when it is used, so that the mouse is no longer a place to hide dirt;
(3) The closed structure of the optical mouse allows the mouse to remain sensitive and smooth after long-term use, and the mouse life is greatly extended;
(4) The disadvantage of the optical mouse is that the resolution is relatively low. Typical resolution: 1000dpi, normal range 800-2500dpi. An optical mouse is a hardware device that detects the displacement of the mouse by infrared or laser, converts the displacement signal into an electrical pulse signal, and then controls the movement of the cursor arrow on the screen through program processing and conversion. The photoelectric sensor of the optical mouse replaces the traditional roller ball. This type of sensor needs to be used in conjunction with a special pad with a striped or dot pattern.
