Compared with the prior art, the utility model discloses an obtain the 9V power in the middle of the signal line of mouse, make the triode switch on through first resistance, then make field effect transistor switch on, make the utility model discloses a 9V DC power supply carries the USB plug, improves electric current signal intensity from this to carry high sensitivity, have the value of popularization and application.
Description
Technical field
The utility model relates to a kind of computer mouse, particularly relates to a kind of high sensitivity computer mouse optical signal amplification circuit.
Background technology
Mouse is a kind of input equipment of computing machine, point wired and wireless two kinds, is also the indicator of calculator display organization coordinate setting in length and breadth, " mouse " (Hong Kong and Taiwan make slide-mouse) of gaining the name because being similar to mouse.The standard address of " mouse " should be " Genius mouse ", and English name " Mouse ", the use of mouse is to make the operation of computing machine more simple and efficient, replaces that loaded down with trivial details instruction of keyboard.And optical mouse of the prior art weakens signal by the impact of data line, cause reaction insensitive, therefore, there is room for improvement.
Summary of the invention
The purpose of this utility model is just to provide a kind of high sensitivity computer mouse optical signal amplification circuit to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises mouse and USB plug, be connected with signal amplification circuit in the middle of the cable of described mouse and described USB plug, described signal amplification circuit is made up of to the 3rd electric capacity, light emitting diode, voltage stabilizing chip, field effect transistor, triode and diode to the 4th resistance, the first electric capacity battery, the first resistance.
Particularly, described battery is 9V, described first resistance is 100 Ω, described second resistance is 400 Ω, described 3rd resistance is 500 Ω, described 4th resistance is 2k Ω, described first electric capacity is 300uf, described second electric capacity is 470uf, described 3rd electric capacity is 100uf, described voltage stabilizing chip model is REG1-7805, described field effect transistor model is IRF9540, described triode model is PN100, described diode model is IN4004.
The beneficial effects of the utility model are:
The utility model is a kind of high sensitivity computer mouse optical signal amplification circuit, compared with prior art, the utility model adopts and obtain 9V power supply in the middle of the signal wire of mouse, triode ON is made by the first resistance, then make field effect transistor conducting, make 9V direct supply of the present utility model be transported to USB plug, improve current signal strength thus, thus raising sensitivity, there is the value applied.
Accompanying drawing explanation
Fig. 1 is circuit structure theory diagram of the present utility model.
