Hook-UP HDTV AND Computer to Computer speakers ?

Looking for a little help please. I have my computer hooked up to a nice set of Boston computer speakers with a subwoofer. Model BA635. Is there a way to also hook-up my HGTV that is right near my computer so I can get the sound of both the tv & computer coming out of the same speakers (not at the same time of course.)?
I read this some where but still don't understand the hook-up.
You need a mini jack splitter (1 male/ two female inputs) Plug the mini jack into your base speaker. Then get two male to male mini jack cables. (length up to you). Connect one cable from base speaker into back of the Tv headphone input. Connect the other cable from the base speaker into your computer. You will be able to use speakers for TV and conputer without having to touch cables again.
Any help ?
Thanks

It's just a basic "Y" splitter. It should have 1 female jack, and 2 male jacks. One male jack lugs into your PC, other male jack plugs into headphone jack on your tv. Male jack from speakers plugs into female jack.

Simple "Y" splitter will result in the low output impedance of one output shorting out the low output impedance of the other, greatly reducing the signal levels....and might even cause DAMAGE.

You need an Audio Input Switch that can be connected to the L/R (WHITE) RCA Output Jacks on your HDTV (may require an Adapter Cable) and plug into the (Green, Female) mini-jack output of your computer. The switched output of the switch needs to connect to the (Green, Male) mini-jack input CABLE from your Boston BA635 Computer Speakers. There is no other way for the BA635 to accept external signal input:
http://ec1.images-amazon.com/media/i...L000010448.pdf

I was surprised I couldn't find a 2-Input Switch with ALL 3.5-mm mini-jack Inputs/Output.....which would (PRESUMABLY) only require ONE Dual RCA (Male) to 3.5-mm (Male) Adapter Cable for connection to HDTV's Audio Output:
http://www.amazon.com/Parts-Express-...+to+3.5mm+male
Perhaps you can find one...but beware there are several OUTPUT Switches to switch between Computer Speakers and Headset....I can't vouch as to whether they are suitable....or NOT.

Here is ONE EXAMPLE of a (moderate cost) Audio Switch with BOTH RCA and 3.5-mm inputs:
http://www.amazon.com/TC-716-Stereo-...jack+%2Bswitch
You'll ALSO need a Dual RCA (Male) to 3.5-mm (Female ) mini-plug Adapter Cable to connect the Switch Output to the Computer Speakers (Green) Mini-Jack Cable:
http://www.amazon.com/Male-3-5mm-Ste...1V75HPFQ5AWWMW

ALTERNATIVELY, you can use a very inexpensive ALL RCA Audio Switch such as the following EXAMPLE:
http://www.amazon.com/3-Way-Switch-S...a+audio+switch
Which will require one Adapter Cable with 3.5-mm (Male) mini-plug on one end and Dual RCA (Female) on the other to connect an Input to the PC:
http://www.amazon.com/Parts-Express-3-5mm-Stereo-Cable/dp/B0002KR1OG
And a second Adapter Cable with 3.5-mm (Female) mini-plug on one end and Dual RCA (Female) on the other to connect the Switch Output to the Cable Input on the Computer Speakers:
http://www.amazon.com/dp/B000I23TTE/...SIN=B000I23TTE

Thanks for all the info. I will have to diagram this out on a piece of paper to understand it better but I think I know what you mean.
THANKS for all the help.

I don't see how this is going to plug into my computer ? Wouldn't I need one of each one of these and the other cable you showed ??

WOW....that is strange...I can SEE the right link in my above post, even after I changed to a shorter version, but it goes somewhere ELSE....try the fol. link (6-ft Belkin cited above also works):
http://www.amazon.com/Parts-Express-.../dp/B0002KR1OG
It's 5-ft cable with Dual RCA (RED/WHITE) Male connectors on one end and a 3.5-mm (Male) mini-jack on the other that plugs directly into the (Green) Audio Output on the PC. Cheap, FREE shipping with no minimum charge required.

Too many options swirling around in my head, I GOT IT WRONG.....above "ALTERNATIVE ALL RCA SWITCH" Post #5 is now correct, where I added:
And a second Adapter Cable with 3.5-mm (Female) mini-plug on one end and Dual RCA (Female) on the other to connect the Switch Output to the Cable Input on the Computer Speakers:
