The mouse is one of the standard fitting of computers, and one of the indispensable products in life also. The early mouse inserted a lot of sensors internals, therefore it’s heavier, but with the development of the science technology and the enhancing of production processes,the mouse now is more and more small and lightweight. But this kind portable mouse greatly effected the using feels for the game players. Because most game mouses need to precisely locate, which is derived from the continuous improvement of the optical identify chips. But different people has different “feels” caused by their subjective thoughts to the mouses. And because the people’s grasping  intensity of the mouses is different, some people like to handle it mildly, some people like a little heavier. Therefore, if the user believe that this mouse does not have the "feel" for himself, then the mouse precisely located will be gone.

 

In this case, to increase the mouse counterweights can be a good solution to this "hard to please" problem. According to different needs of individuals, to increase the different weight counterweights. That is to adjust the center of gravity of the mouse by increasing counterweights to ensure the stability of the mouse. Currently, the tungsten alloy mouse counterweights are mainly used in gaming mouse.

 

The embedded mouse counterweights are divided into two types: fixed type and regulated type. The purpose is to allow the game players have a good feel when using the mouse to play games, and will not feel that the mouse is very empty. Regulated type mouse counterweights compared to the fixed type will be more popular, because users can adjust the counterweights autonomously to satisfy himself by increasing or decreasing the weight of embedded counterweights. General mouse counterweights are made of iron pieces, but for some more stylish designed (holes hollow) mouse, the hand sweat will corrode the iron pieces when using for a long time. If using lead counterweights, because it’s a toxic material, which can harm the human bodies as time goes by. Based on this, tungsten alloy as a high density, non-toxic and environmentally friendly materials can be appropriately used to make the gaming mouse counterweights.
