How do you add a headphone socket to the speaker wires so that the speakers disconnect when the headphones are plugged in?

== Each speaker is driven by a pair of wires coming from the amplifier. One wire is "live" and the other wire is "ground". There are two little contacts in the headphone socket which connect the amplifier's live outputs to the headphones when the headphone jack is inserted. When the headphone jack is removed the contacts reconnect the outputs to the speakers. So it's important to connect the "live" side of each of the speaker lines to these switches - not the "ground" wires which should stay connected to the speakers! Because headphones usually have a much higher impedance than speakers the headphones will draw a lot less power from the amplifier but that won't do it any harm so there is no need to add any extra resistors in the leads. == Connect it to one side of the speaker line. You'd better have a resistor in the lead going to the earphone.

this happened to me. the speakers on my Laptop wouldn't work but when i plugged in my headphones, it worked fine. what i recommend is for you to take a pair of headphones and plug them into a slot with a microphone icon that is usually next to your headphone slot. ! it worked for me!! best of luck!

Is FM radio on chocolate touch free?
Yes, the FM Radio is free! But you have to plug in headphones to make the radio work because the LG Chocolate Touch uses the wires of the headphones as an antenna. However, you still have the option of listening through the phone's speakers instead of the headphone's speakers... as long as some sort of headphones are at least plugged into the headphone slot (even broken headphones would work! as long as there is still wire going into the phone's headphone slot)! Very fun phone! Source: I own a LG Chocolate Touch VX-8575

When you plug your headphones into your computer it reads it as a speaker and nothing plays out of them?
It likely that you plugged your headphones into the wrong jack. There should be a jack for your headphones on your computer that has the head-phones label on it, not the one with speakers or for a microphone.
Why aren't your headphone's working they are plugged in and full volume but you can hear it out of your laptop?
Well it could be because of your headphones or your computer could be using the wrong output it depends. Check that you are using the correct socket. Plugging external headphones or speakers into the socket, should switch the internal speakers off. This isn't happening, so something is fundamentally wrong. Consult your users manual. It could be under software control in your sound settings.

What does speakers and headphones look like?
you can tell its a speaker if its a box or shell, and one end has a grate or mesh covering, there will be a wire coming out of the side opposite to the grill. this wire needs to be plugged into your amp, computer, or sub woofer, depending on your PC audio setup, for more information, contact your PC manufacturer, or try www.fixya.com. Now onto headphones. you can recognize headphones by their distictive "U" shape. there will be bulbus ends on this "U" shape and on the inner part will be soft cusions. you want to invert this "u" so it looks like "n", then place the cusions over your ears so as to sit comfortably and completely cover them. plug the wire into a hole of the smae size with a picture of the headphones themselves near it, or the word "headphones". In all cases, a plugged in speaker or headphone will sound out if you play a song, etc. while plugged in.
