Simple Front Headphone Sockets My Lian Li PC-50 came with two front USB ports under a flap, but no front audio ports. I've recently started online gaming, so a headphone and mic socket on the front would be very useful, all that reaching around the back to plug in the headphones was really annoying. So I've modded a headphone and a mic port into the front, and wires go through the case and out the back into the sound card. Plugging in the headphones kills sound to the speakers. I'll go through how I made the headphone socket, but the mic socket's made in a similar but simpler way. The mic lead is basically just an extension lead mounted in the front panel. -------------- Parts One 3.5mm stereo jack plug. I got it from Maplin. It's a FJ99 and cost 99p. Two 3.5mm PCB mounting stereo jack sockets. Again, from Maplin. They are FK20W and cost 99p each. This magic socket has 5 pins on the reverse. Without a jack plugged into it, the signal goes in through the wire from the sound card, then straight out again down the other wire to the speakers. If a jack is plugged in to the socket it physically breaks the connection to the speakers, while letting the signal go to the headphones. I also needed a few metres of headphone cable. I butchered an old headphone extension lead, but any cable with three cores should do. -------------- Making the wire 1) Wire up the mini jack to the end of the cable, making note of which connection goes to the tip, centre ring and outer ring. 2) Plug the jack into the sound card. Run the cable where you want it to go, through the case to where the port in the front will be. Then cut it to length. 3) Wire up the socket. a) The outer ring on the mini jack is ground and solders to the single middle pin. Use the clear top on the socket to work out which pins you need to solder the other two wires to. b) Then wire the cable that will go to the speakers on to the socket. Again, the ground is soldered to the single pin. The left and right wires go onto the remaining two pins. Again, check to see which ones are correct. 4) Wire up the other socket to the free end. This will be where you plug in the speakers. Just wire it up the same as the first stage of part 3. 5) Wrap the sockets in electrical tape to stop any shorting on the case. There you go, one cable ready to install. The socket with two wires going to it mounts in front of the case, the other one (red) is for the rear. -------------- Socket Mounting Drill a suitable size hole in the front of your case and mount the socket screwing it up tightly. The grey wire is my mic lead. Run the cables through the case. Drill a hole in the rear of the case for the speaker socket. Mod a blanking plate and pass the wire through the back of the case and plug it into the sound card. -------------- End Result Ta da!
