ABSTRACT:
The present invention relates to a method for preventing an output device from being damaged, which comprises the steps of: dividing the output value of an output device into a plurality of areas, defining a ratio value to every area, receiving a desired output value, determining the current area where the desired output value device is located, and calculating the desired output value with the ratio value to obtain an actual output volume and output the actual output volume.
