Laptop only has one speaker port and surround speakers need 3

I have just bought 5.1 surround speakers for my laptop. The speakers have 3 jack plugs but there is only one port on my laptop. Do i need some kind of 3 in 1 adapter and where can i buy one?

 

you can use a 3-1 adapter. You can get them at most electronic stores and in some electronic sections of stores such as: Wal-Mart,Lowes, Best Buy, Radio Shack, Home Depot. I hope this helps. If all Hope Fails look on line for the adapter
