RCA to headphone/speaker adapter - does it exist?

Hello!
Now, maybe I'm crazy, but I recall having an audio adapter three years or so ago that allowed me to connect the audio RCA cables from, say, a DVD player or a game console into it, and it also had a female headphone/speaker slot. I used it to hook my dvd player and consoles directly to my speakers. Unfortunately, I don't have it anymore...

I'm looking for something like this again - either the same type of adapter, or perhaps a combination of two might have the same effect. I'm currently living in a very small dorm-like room with a roommate and very thin walls (as a result, the dorm has a 24 hour per day "quiet rule"). However, I'd still like to listen to my video games... but the small television I'm stuck using doesn't have the headphone jack.

Any advice would be greatly appreciated. Thank you very much!
