First of all, the magneto-optic fretting of the mouse may be relatively unfamiliar to everyone. Therefore, this article is intended to bring you to understand the magneto-optic fretting and to understand the advantages and disadvantages of magneto-optic fretting. I recently started with Fuller's G90 mouse, which costs 99 yuan. It is positioned as an entry-level gaming mouse. Magneto-optic fretting is the only bright spot. So I asked two questions for this mouse first.
1. What is magnetostrictive motion in the end?
2. What are the advantages and disadvantages of magneto-optic fretting?
Familiar with the mouse structure of the small partners know that micro-motion is a mouse click trigger switch, to a certain extent, determine the mouse's click feel and life. Everyone familiar with Omron, Kaihua, and Cherry has its own mouse micro switch, and the types are quite abundant. Once the mouse double-clicks and clicks to confirm the problem, it can be solved by changing the jog. Today, we must take everyone’s knowledge of magneto-optic fretting. Please see below. You can see that with a complete set of springs, magnets, molds, and optical coupling switches to form a mouse "trigger system", this is the magnetostrictive micro-motion. Magneto-optical represents optical coupling switches and permanent magnets. In fact, micro-motion has no practical significance, but it simply replaces the role of traditional mouse micro-motion.
After dismantling the Fuller G90 mouse, the structure of the left and right keys magneto-optic micro-movement mold is still relatively complicated compared to the traditional key column. The left and right button assembly is somewhat similar to the large Logitech mouse button tension system of the past two years. The connection of the G90 through the spring is indeed to eliminate the key empty key process. Solved a big problem in the mouse world.
The yellow circle in the picture is the photoelectric switch on the PCB. After the mouse is powered on, the photoelectric switch will emit light. This switch is like the current popular mechanical keyboard optical axis trigger switch. When it is used to the mouse, it becomes the mouse button trigger switch.
In addition, the button assembly, the spring lever, the permanent magnet, and the permanent magnet are restored to the original position by the magnetic force. It is more sensitive than conventional micro-motion springs (at least when new mice are used, it is not known whether the magnetic properties of permanent magnets will stand the test of time). At this yellow circle, there are units that control whether light passes or not. I don’t know if the light is passing through the trigger switch when the left and right keys are pressed, or the switch is triggered when the light passes through the state when the left and right keys are pressed. This is actually the same, and can be achieved through the kernel's calculation settings. Effect.
After the introduction of "Magnetic Micro Motion", let us talk about its characteristics.
Advantage 1: Solve the problem of empty key path
Fuller's G90 mouse magneto-optic micro-motion, the biggest advantage is to solve the problem of the empty key path, which is what all the mouse are trying to achieve, including my above mentioned Logitech, through the complex key tension system To solve, the cheapest G302 mouse also has a price of nearly 200 yuan, not to mention the high-end G303, G403 and so on. (The following figure shows the key column structure of Logitech G303)
Advantage two: Theoretically, the life of the left and right mouse buttons is improved.
Because the life of the keys does not depend on the metal shrapnel and contacts in the mouse's fretting, it uses optical coupling switches, magnets, and spring levers to work together. It should be said that the physical wear of the keys is quite small.
Advantage three: Buttons rebound quite quickly
Instead of relying on traditional micro-moving shrapnel, the magnetic force of the permanent magnets is used to control the rebound. This makes the keys rebound very quickly. In the intense RTS games and MOBA games, they can take the lead and win the battle.
Disadvantage 1: The button sound is too loud!
The key sound may actually not be too much attention in the fierce game, but it is because of the sound that it always feels that the trigger is not fast enough to form a psychological obstacle. Or at night, it may disturb the roommate’s study break. Therefore, the key sound is the biggest drawback of the Fuller G90.
So I set out to start the transformation. The so-called failure is the mother of success. After some detours, I finally found a solution that was fairly OK.
1. First apply some lubricating grease on each contact of magneto-optic micro-movement. (Reducing the sound does not help much, but the reduction of the button strength has played a minor role)
2, attached to the layer of double-sided adhesive on the spring lever (played around a rubber, to reduce its vibration, but the effect is not obvious, PASS out)
3. Finally, a combination of a child bumper strip and double-sided tape was used to place a “small device†for reducing vibration on the spring lever and the side of the ABS plastic wall. Take a look at the picture below, successfully knocking the key click of the magneto-optic fretting to the level of ordinary mouse fretting. (It must be tried many times here, it must not be a great resistance to the spring lever, but it cannot touch the lever, so it is better to touch it slightly)
Disadvantage 2: The intensity of the keys is emphasized.
In fact, the traditional micro-motion is also the size of the button strength, but this Fuller G90 magnetic micro-motion use, still feel a bit biased, I may use Omron's 10M, 20M fretting used to. Still want to do a tuning of their button strength. The problem was solved by applying some lubricating grease on each contact of magneto-optic micro-motion.
At present, the magneto-optic micro-motion of the mouse is still a relatively new thing. The interested partner can purchase the Fuller G90 mouse and try it out. Finally, attach the purchase address.
