In my Laptop there is only 1 Audio Jack and I am Forced to use a Audio jack splitter for the mic then the mic works but my built in speakers of the laptop don't work and then I hv to wear Headphones which is irratating so is there a way i can use the mic and also use my built in speakers
Nope--I don't think so. When you plug in the plug, this is detected by the HW and the internal speakers are automatically disabled. Annoying. The way to know for sure is look at Settings/Sound. I expect what you will see there is that for the output device you can select is speaker/headphone. In other words, you can't route to just one or the other.
