Embodiment Construction

[0018] According to the control device for dynamically adjusting the volume of the system by using the mouse wheel 200 provided by the present invention, please refer to figure 1 To illustrate its main components, which include:

[0019] (1) Press signal receiving unit 100 : used to receive a press control signal provided by the mouse when the mouse wheel of the mouse is pressed.

[0020] (2) Scrolling signal receiving unit 110 : used to receive a scrolling control signal provided by the mouse when the mouse wheel scrolls.

[0021] (3) Functional truth table 130 : storing volume control commands corresponding to the control signal and the scroll control signal. The function truth table also stores the values ​​of the pressing interval time parameter, the starting parameter value and the scrolling amount parameter value. Among them, the parameter value of the press interval time specifies the interval time of effective press times of the mouse wheel, and the start parameter v...
